Rough Hewn Trio – Some Live Excerpts

Posted on by
Reply

The Rough Hewn Trio –  an instrumental trio consisting of Chris Lavender on Warr guitar, Craig Bunch on drums and myself on guitar are getting back into the rehearsal cycle and gearing up for some shows this spring.  To get a feel for what the shows will be like here are some live excerpts from some improvisations we did this fall.  The live sets – will include a combination of pre-composed and improvised material.

For those of you who are interested – this session is all drums and laptops.  I’m running Pod Farm and Sooperlooper and Chris is using Guitar Rig. (an amp was used to re-amp the guitar in 1C – which had some gnarly digital distortion tho…)

Note:

mp3 playback is sometimes a little glitchy in Safari.  If it doesn’t play in your web browser – you may just have to reload/refresh the playback page.

Enjoy!

AU LAB/POD FARM 2.0/LIVE LAPTOP RIG TUTORIAL PART 6 – Dual Rig Distorted Tones

Posted on by
Reply

In previous instances – I haven’t had a whole lot of success with running both A and B channels on a dual rig – but I thought I would try to steal a tone idea from Joe Bonamassa, and give it another shot – this time running a dirty and clean tone at the same time and blending the two for a more complex tone.

This post won’t be as in-depth as some of the other AU LAB posts I’ve done as I’ve detailed a lot of the process already.

As a starting point – here’s the DIST 2 rig:

The pedal configurations are very similar to what I set up here:

The wahs and volumes are both assigned to the same pedal so that 1 pedal controls both functions.  Ditto for the distortion and the reverse delays (usually off) which I can kick in for some grand psychedelia.

In the next version of this rig – I would probably set the Mix knob of the delays to the expression pedal so I could dial in the amount of reserve delay I wanted when it was on.

As another option – you could also set the volumes independently – one to the short board volume and one to an expression pedal –which would allow you to have a clean tone and dial in the amount of distortion you wanted a la Jim Thomas of the Mermen.

EQ

One of the biggest problems I’ve had when using dual rigs in the past is a weird boosting of certain EQs.  Particularly on the low E string.  In this case what I’ve done is to cut the bass in the 80 Hz by 6db on the Graphic Eq in the signal chain.    This was an idea I got from a REALLY cool acoustic post that Bob Brozman had on his site detailing his live rig and correlating specific Eq ranges to strings.  It worked pretty well and helped tame the woof on the low E string.  There’s also a 3db boost at 750Hz and a 2db cut around 3k.

Kicking on the distortion on the distorted side take out some of the extreme low-end and compresses the low E string in a pleasing way.

The Tube Screamer settings I’m using are:

Drive 24%

Gain 66%

Tone 13%

Another thing that has helped with this is splitting the Stereo send.  I’ve panned these to 27% on either side.

Here’s the mixer setting:

Another important note – this is running out mono to an amp – so that will further affect the sonic split.  I’m running the rig in stereo because I like the sounds of the effects in stereo better than mono – but ultimately this is going down to a mono signal.

Here are the Silver Marshall Model Settings:

In live use – the Atomic is really bass heavy – so I’ve cut out a lot of the bass here and typically have it at 3-5 depending on how the room sounds.

Gaining Perspective

Another problem that comes up with laptop guitar – or modeling in general is that it’s really easy to overdo it on the gain.  When I got my first distortion pedal – I remember turning all the knobs up 100%.  It took a while to get to where I started experimenting with eq and gain staging to try to get some saturation – but keep the overall definition.  The use is gig specific –  If the sound requires a lot of gain and sludge – then I go for that – but in general – I definitely try to scale it back a bit.  I can always add an overdrive or distortion pedal if I need to increase the amount of gain – .

And the clean settings:

The volume is a constant adjustment issue here. (also note the eq differences from the settings in the AU lab tutorial).  Here – I’m just trying to find some good mix of dirty with a bit of clean for clarity.

Here is a short example of the tone – this uses the clean channel from the fender and the dirty channel from the Marshall.  This was just the setting with the same AU lab settings in the AU lab posts – recorded directly in AU lab.

One thing I realized after I tracked this is that the feedback on the Tube echo is set a little too high.  I usually leave them both around 4 so it gets a little verb/slapback sound.

I have the tube drive on the Fender off for this example but can switch it on for extra gain if I need it.

In the meantime – you can download this tone here.

Hopefully this has been helpful.  I’ll be doing a post on using AU lab as an acoustic pre for live use soon.

Recycling Shapes or Modular Arpeggios for Fun and Profit

Posted on by
Reply

When improvising, I need to be able to access sounds immediately.  One tool that I use for this is Sonic Visualization (which is really a cornerstone of the GuitArchitetcure concept).  In Sonic Visualization – I associate shapes with sounds so that I can make changes, modify  or develop ideas in real-time.  Here’s one example of this in action and has some cool ramifications for application.

For the audio examples – I’ll be using a Line 6 variax AC 700 strung with D ‘addario .012 phosphor bronze strings – to show that this can be performed on an acoustic guitar.  I used the line 6 as I could record it direct into the laptop in AU lab and not have to use a microphone.

First:  Here’s an example of this approach played at tempo.

Now let’s start slowly and see how to get to that point.

Let’s say we were going to solo over an A5 chord.

Since there are only 2 unique notes (A and E), you could play almost any type of scale or arpeggio over it – but for a moment – let’s look at a minor tonality.

If I was playing straight up metal, I might just play an A minor arpeggio over it.  There’s nothing wrong with this sound – but I want to spice it up a little.

One thing I’ll do as a starting point is to extend the arpeggio. Instead of just playing an a minor triad (A, C and E) – I’m going to add a G and a B to the arpeggio creating an A minor 9 sound.  Here’s the form I’ll be using:


Some quick notes:

Fingering – basically I view this as a positional form so I’m using the 1st finger for notes on the 5th fret, 2nd finger for the E on the 7th fret, 3rd finger for the C on the 8th fret and the 4th finger on the B on the 9th fret.

Hand tension – As your playing through this shape – you want to keep your fretting hand as relaxed as possible.  The more tense your hand is – the more difficult this will be to play.

Picking – you could play this with alternate picking or all hammers – but I’m going to recommend a specific picking pattern for this arpeggio:

Notice that it starts on an upstroke and then uses all down strokes.  This picking pattern will become very useful as this process continues – but if you don’t have a lot of experience sweep (or rake) picking, you’ll need to keep your picking hand relaxed and work on getting the attacks all happening in time.

Timing – you’ll notice that this is a group of 5 (i.e a “Quintuplet” or “Pentuplet”) which means that you are playing 5 notes to the beat.  The  key here is to make sure that you are playing the notes in an even division – (i.e. the same length of time for each note and each space between the notes).

Here’s an audio example of just the arpeggio – first played slowly and then at tempo.

Note: in some browsers (Safari in particular)  the audio doesn’t always load properly in the new window.  If you just refresh the window it usually comes up the second time.

Obviously a metronome will help with consistency – but it you’re having trouble with hearing the division of 5 try the following.

Set up a metronome.

Set the click at a slow enough level that you can play 1 note per click.

Accent the first note and tap your foot to the first note only

Play each note of the arpeggio on a metronome click.

On the repeats – accent the first note and tap your foot to the first note only.  If you can – try to figure out the tempo of the first tones only (a tap tempo feature will help a lot here) and now try playing the arpeggio with only the first accent.  This is annoying to do for long periods of time – but can help a lot for short practicing cycles.

You may want to just start with this one arpeggio and work on synchronizing both hands – that alone could take some time if you’re unfamiliar with this technique.

From a performance perspective – you’re looking for uniformity of attack with regards to both timing and volume.

 

Recycling shapes

Here’s an interesting observation – If we play the same minor 9 shape we just used but this time move it to the 5th of the chord (In this case the pitch E or an E minor 9 arpeggio ), we get the notes E, G, B (which were also in the last arpeggio)but we get 2 added pitches D and F# which here act as the 11 and 13. This creates an over all A minor 13  or A Dorian sound.

Short cut #1 – when playing over a minor or minor 7th chord – you can play minor arpeggios from both the root and the 5th of the chord over it.

 

Short cut #2 – A minor 9 + E minor 9 = A minor 13 or an A Dorian sound.

Let’s look at this in notation and tab:

Notice that by using the same picking pattern –  the upstroke of the B in the first arpeggio leads right into an upstroke on the E of the E minor 9 arpeggio.  The fingering pattern is the same as before.  Once you get the A minor 9 form down – you may need to practice the transition between the A minor 9 and the E minor 9 forms.

Here is an mp3 of the transition played at two tempos.

Finally, we can repeat the same thing on the last A of the A5 chord (although the fingering pattern will have to be adjusted by a fret for the G-B string tuning).

Here’s the top A minor 9  arpeggio played by itself – first slowly  and then faster.

As before, the same picking pattern is utilized to add continuity between the forms.  You could end on the B or pick another pitch the end the form on depending on what chord you’re playing it over.  Here I’ve chosen E.

Here’s the full arpeggio played at tempo.

You say Tomato I say Major

So now that we’ve looked at a minor example let’s use a major example.

If I sharp the C and G notes of the A minor 9 arpeggio –I have an A Major 9 arpeggio – which also works over A5.

Here’s the A major 9  arpeggio played slowly  and then faster.

Here’s another interesting observation – If we play the same major 9 shape we just used but this time move it to the 5th of the chord (In this case the pitch E or an E major 9 arpeggio ), we get the notes E, G#, B (which were also in the last arpeggio) but we get 2 added pitches D# and F# which here act as the #11 and 13.  This creates an over all A major 13 augmented 11 or an A Lydian sound.

Short cut #1 – when playing over a major or major 7th chord – you can play major arpeggios from both the root and the 5th of the chord over it.

 

Short cut #2 – A major 9 + E major 9 = A major 13 (#11) or A Lydian tonality.


Since I’ve broken this process down a great deal with the A minor 9 process – I’ll just highlight the lick idea here.  You could end on the B or pick another pitch to end on depending on what chord you’re playing it over.

Here’s the full arpeggio played at tempo.

Here’s the A major 9  arpeggio played slowly  and then faster.

Taking it out

As a final idea – let’s apply this concept to extending the overall tonality.

Here’s a transcription of an improvisation working off of this idea – but using a B minor 9 for the third chord of the sequence.

First let’s look at the A5 chord again:

Now – let’s realize that instead of building these structures off of the Root – 5th – root of the chord – that we could use other tones – for example here I’m going to use the Root, the 5th and the 9th:

Here’s a transcription of an improvisation working off of this idea – but using a B minor 9 for the third chord of the sequence.

Here’s the full arpeggio played at tempo.

Here’s the  arpeggio played slowly  and then faster.

C# is obviously not part of an A minor tonality – but by sneaking it into the arpeggio sequence it gently nudges the overall tonality to me in a pleasing way.

The point is to not get too hung up on rules or shortcuts – but instead to have a series of modular sounds and approaches that you can use as the need comes up.

I’ll be posting more about these types of approaches in the weeks and (more likely) months ahead.  Just remember in general to keep your hands loose, your rhythm tight and your attention focused – but if this is your first time to the site I’ve posted a number of things on practicing in general which may be helpful to you.

I’m always looking for feed back on these posts!  If possible – please take a minute to comment or drop me a pm @ guitar.blueprint@gmail.com to let me know if these are useful to you.

Laptop Guitar Setup Or Notes From A Live Show

Posted on by
2

For the Onibaba show last night, I decided to use only the laptop rig that I’ve been working with and not use the typical Atomic/Pod X3 rig that I use.  The short of it is that from a technical standpoint – it worked without a hitch.  I don’t think that anyone noticed that there weren’t “real amps” there and tonally it fit the bill.  There were, however,  a few little quirks that needed to be sussed out.

1 The room we were playing in had very high ceilings and was really boomy.  Sounded great on acoustic instruments – but I had to be really careful of not getting washed out tone wise.

2 The midi assignments for Sooper Looper stopped working when I used the FBV express board.  The board worked fine – but I’ll probably just return it and get a breakout box instead.  The FBV Express can control about 6 functions – but ultimately I’d like to control about 10-12 functions – so I think it makes more sense to just trigger it manually.

.

No one size fits all

.

As I’ve mentioned here, there are a number of variances that occur with modeling:

“I’m in the process of working on sounds on the X3 Live for the show – and tweak PA vs. amp sounds.  One thing I’ve noticed with modeling is that there are at least 4 different scenarios for setting up sounds:

1.  Headphone patches – i.e. practicing or recording

2.  Playing through an amp at low volumes

3.  Playing through an amp at high volumes

4.  Playing through a PA.

You might think that there wasn’t a lot of variance – but the differences between these parameters are huge.  I have patches that sound mediocre at low volumes and sound really good when the volume gets goosed a bit.  Headphone patches that work well at home and fall apart live – and vice versa.”

So along this line  I knew I’d have to tweak some patches I’d been using  and make some new ones for the show.  I decided to pull some patches I liked and demo them at low volumes in my apartment and then try to fix anything glaringly wrong at the show.

.

Reverse Engineering or Start with the output

.

A while ago I mentioned I bought a back up Atomic amp from Guitar Center for $149.  The listing was for an Atomic Reactor 1×12 – but both the 50 watt and the 18 Watt are 1×12 – so what I got in the mail was the 18 watt.  Initially, I was a little disappointed – but given that you can run it on 115V OR 240V – I figured it was a good investment and that in a worse case scenario I could sell it and make my money back.

When I set up my sounds – I set them up on the 18w.  There’s no master volume knob – it just runs at 18 watts – but I could control the output with my duet and set things up at a low volume.

The Atomics in general are very bass heavy so I knew from the get go I’d have to roll a lot of the bass down and tweak other mid and high levels.

AfterI got a tone set up on a lark I decided to try to run it stereo.  I pulled out the 50 watt Atomic and there were some weird grounding issues.  While I was trying to suss that out I decided to A/B the amps – and see if there was a difference.  Suprisingly  the 18 Watt sounded MUCH better than the 50 watt.  The 18 watt does use different tubes (2 EL34’s and 1 12ax7a as opposed to the 6l6GCs and the 12AX7 in the 50 watt) – but I think that just having the amp full bore made a big difference.  The more I cranked the output volume on the Duet – the more the tone sagged in a very pleasing way.  Also the 18 watt is DEAD quiet so that solved the issue of the loud fan on the 50 watt version.  I knew the 18 Watt was loud but I wasn’t sure if it was fully going to be able to hang with drums, bass, amplified trombone and the awesome sonic terror of Vinny Golia – but it did.

.

IMPORTANT DUET NOTE: 

When setting output volume on the unit – if you choose “Instrument amp” – you get a flat volume that you are unable to control – by setting it to “Line Level” you can adjust the output with the knob on the Duet.

.

I think the Duet output went to ten – I never went higher than 5 – and at one point turned down to 3.  18 Watts was more than enough for the gig.  The drag now is I like the amp enough to sink more money into it and have I have the desire to get the amp re-tolexed.  Maybe with like a fender tweed or something.  In the meantime I used the 18 watter as a low volume template and could then tweak it further in the space as I needed to.

.

Organization is key

.

One reason to go digital is the rigs themselves they take up so little disk space you could save hundreds of them and have individual configurations for almost any situation.  This is also one reason NOT to go digital as it’s easy to get overwhelmed with options instead of narrowing it down to a few.

A great feature about POD Farm 2  is that you can create and organize folders with drag and drop ease.

For example let’s begin by looking at how I built my live setup:

First – here’s a sample patch:

.

Now if you look over to Setlists:

.

You’ll see I created a folder marked ATOMIC.

.

Tip:

If you want to control changing setlists from a Midi Controller – Just control click on the up or down arrow, in the Setlist window and then press the midi controller feature you want to use to control it

.

Within that setlist, I have a series of patches – I name them all Atomic – so I can find them easily if I have to.

.

Another Tip:

If you want to control changing Programs (i.e different patches) within a setlist  from a Midi Controller –  Go to the top of the screen – where the patch name is:

Just control click on the up or down arrow to the right of the Patch name, in the and then press the midi controller feature you want to use to control it.

I’ve set it up to be used withthe up and down arrows on the right of the shortboard.  I decided to have one  folder marked Atomic and then just scroll up and down through the folder to get to patches. You could just as easily set up multiple folders and organize patches (and if you have only 4 tones per Setlist – you could just A/B/C/D them with the shortboard and use the up and down arrows to go between setlists – just like the setup on the PODs).

When I used the pod X3 with the docking station in the Atomic – one feature I would use a lot was the dual rig feature with one rig with a speaker sim – and one with none – It gave the sound a lift in a pleasing way.  At the gig I just ran them all through the 4×12 IRs I’ve been using and it sounded fine – I may put the IRs on a bus and mix the two to see how it sounds – but this is the rig I’m using as of this post.

Clarity wise – I felt it had a noticeable advantage over the X3 – but I’ll have to do more experimenting.  In a future post – I’ll detail a Dual distortion tone I’ve been developing and discuss some more specifics with using a laptop as a guitar processor live.

AU Lab/POD Farm 2.0/Live Laptop Rig Tutorial Part 4

Posted on by
1

Welcome back!  In this post, I’ll be integrating SooperLooper into the AU LAB Live rig I’ve been building.  If you haven’t read the earlier posts about this (part 1, part 2 or part 3) you may want to read those before continuing on.

An Important note about sample rates:

From here on out – if you’re going to be incorporating other audio into the session (including looping in SooperLooper) – you’re probably going to have to set the sample rate back to 44.1 (and set the Impulse responses back to 44.1).  If I’m not looping –  I try to set the rate as high as I can, but know that it’s going to have to get bounced down to 44.1 for recording, etc.

SooperLooper:

The next step is to set up Sooper Looper to be able to loop audio.  I’m going to put SooperLooper on a bus, so I can either send audio to it or bypass it as need be.

In AU LAB – – > Sends – Select BUS 1.

A new Bus Strip will open.

Under Effects – scroll down and select Sooper Looper.

When you do this, Sooper Looper will open up in 2 windows:

The first window:

And then the GUI

A Quick Tip:

When using sooperlooper, you need to increase the “main in mon” to hear any output.

You can set up multiple stereo loops in Sooper Looper by selecting them from the SooperLooper menu.

I like to have 4-5 different loops set up.

You could do more (your limits are your system resources- but since I’m on a laptop – I want to be able to see everything (and this takes up some screen space).

Another Quick Tip:

You can set SooperLooper up for midi controls but the key binding options will help you navigate the window pretty easily as well.  They’re found under SooperLooper Preferences.

For example – you need to select an audio loop in order to record to it.  If you look at the bindings above you’ll see that select_loop_1 is currently set to “1”.

So if you’re on the active SooperLooper window and hit 1 – you’ll arm track 1. (Note the new line to the far left of SooperLooper that shows which track is armed for recording)

Make sure to save your AU Lab session.

Setting up MIDI control in SooperLooper:

In the first SooperLooper window:

Click on the arrow next to essej.net: Sooper.

Select Midi Effect Editor

Set the MIDI Source to the controller you want to use and set the Midi Channel to the channel you want to use.

Note:

If you don’t see the controller then go to Audio-Midi Setup application (or you could find it in the Application – –  > Utilities folder) and click on the MIDI tab.

To Set up specific commands in Sooper Looper, you’ll need to go to Midi Bindings under SooperLooper Prefereces:

MIDI Binding Steps in SooperLooper:

Click “Add New”.

Select a command under “Command/Control”.

Click “Learn”.

Press the midi control you want to use to control the function.

Click “Modify”.

When you get all the functions learned  – click Save.

Also make sure you save bother you SooperLooper AND your AU LAB session.  All the midi functions should be there when you reopen it – but if they aren’t and you’ve saved them in Sooper Looper – you can just “Load” them back in.

AU Lab : Transport

Here’s something pretty cool – the Window tab in AU Lab – select Show Transport

That will bring up the following window:

The MIDI Clock Source will probably default to Disabled – If you set it to Internal – you can use to tap tempo feature to synch effects or Sooper Looper  by tempo.  Pretty cool feature!

(Also in the the Window tab in AU Lab there are some other useful options particularly –  Show CPU Load – which brings up a handy visual meter to let you see how your project is doing with it’s resources.)

Additional Resources: SooperLooper

SooperLooper is an incredibly deep plug in.  It would be easy to devote a 5 part article to just the feature set and use of it – The  Sooper Looper forum is also extremely helpful with various Sooper Looper issues, and also has a specific SooperLooper AU LAB section.

Next time – I complete the rig (for now)

You can find all of the laptop guitar rig posts on the Blueprints tab on the top of the page.  Once on the blueprints page – just scroll down to the Laptop Guitar Rig section.

AU Lab/POD Farm 2.0/Live Laptop Rig Tutorial Part 3

Posted on by
Reply

Hello again.

If you haven’t read the first or the second posts about setting up POD Farm in AU Lab, you may want to review those first.

Automating Parameters with MIDI Learn:

Now let’s complete the clean guitar setup and then automate some parameters in POD Farm.

First I’m going to delete the delay and add a volume pedal.  You’ll find it under “Dynamics”.

It could just as easily go before the amp, but in this case I want to put it between the amp and the delay, so I’ve deleted the Analog delay and placed a Tube echo after the volume pedal.

Next I’ll add a wah.

And an overdrive pedal.  I’m going to have a full on distortion tone on the other channel – but this gives me another tonal option.

Across the Very top of the Pod Farm Window (labeled Audio 1: POD Farm 2 (1))

You’ll see 4 tabs underneath that window reading from left to right:

Audio1 –> POD Farm 2(1) –> Untitled –> Line:6 POD Farm 2

Select the arrow to the right of Line:6 POD Farm 2 and scroll down to Midi Effect Editor:

You’ll notice that the MIDI Source is None – which in this case means that the shortboard is getting power and sending midi, but it’s not being received by POD Farm/AU Lab.

I’ve selected the POD short board for the MIDI SOURCE, and will keep it on midi channel 1

POD Farm: Midi Learn – Volume

Now that the midi signal from the shortboard will get to POD Farm, I can use the Midi Learn function.

Let’s start with the volume pedal.

If I select the volume pedal in the signal chain a close up of the pedal will open up in the window above the signal chain.

Since I want to control the volume of the pedal  – I want to cntrl – click the level knob on the pedal.

That brings up the following option:

Choose MIDI Control – – > MIDI Learn.  Now if I move the volume pedal with my foot the level on the screen will change as well.

(If you make a mistake you can choose the “Clear” option above MIDI Learn and repeat the process.)

Note:

If you wanted to do this with a distorted amp and roll off the gain, you could select the amp and cntrl – click the Gain knob.  Even better, with the “Set min to current pos/Set max to current position” you could use the volume pedal for subtle variations in gain.

POD Farm: Midi Learn – Volume

Let’s see how this works with the Wah pedal.

First, as opposed to the volume pedal, which is always on, I want to be able to turn the wah pedal on and off.

The “secret” here is to automate the On/Off button under the “Gate” Button.

By selecting the MIDI Learn function and pressing down on the toe switch, that switch now turns the pedal on and off.

Next, with the toe switch on – I’m going to set the volume pedal to control the WAH sweep.  Just cntrl-click the actual wah switch for MIDI Learn and move the pedal.  The pedal will now control the sweep.

I like the Chrome Custom pedal, but don’t like the extreme high end, so I’m going to limit the scope of the sweep.  I’m going to turn the knob to 85% or so and then cntrl- click, but this time instead of selecting MIDI Learn, I’m going to choose “Set max to current position”.

Now when I sweep the wah it only goes from 0-85%.  This is really useful if you only want to filter a specific bandwidth.

I’ll set the Overdrive to an on off setting – the same way that I did with the wah.

That is enough for a general clean tone.  Now onto…

The Dirty Channel:

I’m going to spend a lot less time on this as I’ve already shown how to set up and automate effects on the clean side.

Here’s the default set up:

A brief note on tone:

In distorted models, you can create amps with gain structures that you could never create feasibly in the real world.  One problem I hear a lot is the desire to crank the gain and cut all the mids.  That creates a particular sound – but it’s not one that cuts through very easily.  The overdrive will boost the channel a bit in general, but it’s easier to ADD distortion live than it is to take it away.  Again, louder isn’t always better.

Basically I’m using the same Volume, Wah and delay as the clean channel above.  The only differences are in the amp and overdrive pedal (and that I’ve moved the placement of the volume pedal.)

Here’s the overdrive setttings:

POD Farm: Midi Learn – A/B Switch

The next step is to set up a midi command to be able to switch from the A to B channel.

The secret here is to click on the mixer button so the A/B Box appears in the window above the rig.

All I have to do then is cntrl-click the A/B button and select a button on the shortboard and then it’s all set.

Save your Bacon:

Hopefully you’ve saved your POD Farm patch and your AU Lab settings, but if not saving them both are very self explanatory.

Let’s start with POD Farm:

Click to the left of Default and save as

In this stage, you can also make whatever notes you want as well for later reference which is a nice feature.

Another really cool thing about AU Lab is that when you save AU lab – it saves the settings on all of the effects in AU Lab.  So save OFTEN.

That’s it for this post.  In the next post, I’ll add Sooperlooper into the rig.

You can find all of the laptop guitar rig posts on the Blueprints tab on the top of the page.  Once on the blueprints page – just scroll down to the Laptop Guitar Rig section.

AU Lab/POD Farm 2.0/Live Laptop Rig Tutorial Part 2

In the previous post, an AU Lab session (or document) was established and an A/B POD Farm patch was created.  In this post, I’m going to start modifying the patch to make it more useable.

Building the rig:

Okay first I’m going to swap out the amp. I like the Double Verb instead.

You can drag and drop amps into the signal chain, but if I click on the down arrow to the right of the AMP field – I can just scroll down to the Double Verb amp.

Here are the settings I’m using.

If you look in the left hand corner underneath the input knob on POD Farm, you’ll notice the global gate is on.  I tend to use the global gate at a low setting.  This came from a ruined session where I switched to a distorted sound that DIDN’T have a gate on it and squealed between each phrase.  Now I keep the master gate on to not worry about that scenario.

Compression:

Louder isn’t always better.

Compression has it’s place – but I try to play dynamically, so the compression is the first thing to leave the POD farm signal chain.

If you click on the compressor in the signal chain and then ctrl-click on the compressor you’ll get the following options.

Just select Delete.  If you change your mind you can drag and drop another compressor from the menu into the signal chain.

Another point to bring up, is that when I use an amp and effects – I try to use the same signal chain for all of them.  (This comes from years of playing gigs and having a bunch of effects pedals going through the same amp and reverb).

Looking at this set up, the mic pre (currently between the amp and the reverb) would be something that I would want in the channel signal chain in AU LAB instead of POD Farm – so that it was the same mic pre for any amp I’m using.

The first step is to delete the mic-pre from the POD Farm signal chain (using the same method as the compressor above).

Next (in AU LAB) in the Audio 1 channel – click on the arrow in the next available Effects field below PODfarm .

If you scroll down to Line 6, you’ll see that in addition to PODFarm, that each individual component of a PODfarm rig has been broken down into components (aka POD Elements).  This is so you can use individual effects or amps as an AU plug in which much less of a CPU hit than loading in another instance of POD Farm.

In this case choose: POD Farm Element – Preamp.  I’ve chosen Vintage UK.

Reverb:

The reverb would also be something that I would want in the channel signal chain – so that it was the same reverb for any amp I’m using.  (The other advantage is that by placing the reverb outside of POD Farm, when I change amp settings the reverb doesn’t cut off with the amp change.)

Delete the Reverb from the signal chain in POD Farm (using the same method as the compressor and the mic-pre above).

Next, (in AU LAB) in the Audio 1 channel – click on the arrow in the next available Effects field below POD Farm Element – Preamp.

If you scroll down to Line 6, choose: POD Farm Elements – Reverbs.  I’ve chosen Standard Spring.  Here are the settings I’m using.

Impulse Responses:

I use impulse responses rather than the speaker sims in Pod farm.  So the next thing I’m going to do is get rid of the speaker cabinet/microphone on Podfarm.  If I click on the CAB button – I’ll get a list of speaker cabinets and microphones used.  If I scroll to the top of the list – I’ll get “No Cabinet” which deactivates both the cabinet and the microphone.

Next, (in AU LAB) in the Audio 1 channel – click on the arrow in the next available Effects field belowPOD Farm Element – Reverbs.

Scroll down to Lernvall Audio and select LA Convolver.

Now I’m going to select to impulse responses to act as a speaker simulator.  I’ve experimented with putting multiple instances of LAConvolver  on buses and running multiple cabs, but since I want to run SooperLooper in the bus (Where I can loop guitar and any other incoming audio source), I’m going to just stick with a stereo set.

Select a channel and hit “choose” under file. In this case I’m using the free RedWirez cabinet I got as part of their birthday giveaway.

I want to use a high sample rate to get better definition so I’ve chosen 88.2 K. (or 2 times 44.1k)

I’ve chosen an SM57 on the grill and a KM84 about 3 inches behind the back of the amp.  I tend to start with the Wet gain in the center position and adjust as necessary.

A brief note:

I’ve mentioned this in other posts, but since I want to use the same speaker cab for all the amplifiers, I’m going with a 4×12 for familiarity.  Normally,  I wouldn’t match a double verb up with a 4×12, but since I’m going to be running a Marshall on the other channel, I’m going to just have to adjust the clean amp signals accordingly.

Fixing the Sample Rate:

If you notice, the plug in sample rate and the Impulse response sample rates are different.  It will work like this – but I want to use the highest sample rate I can for the most clarity.  There is a delicate balancing act that comes between high sample rates, stability and useable latency, so everything here is a compromise.

I’ll fix this with Audio Midi Set up :

First: click on AU Lab and look under Preferences.

When the preferences window opens, click on the tab marked Devices.

If you click on the expert setting arrow you’ll see something like the following:

Another  brief note:

I’ve set the CPU to 100% to avoid glitches.  I’ve also set the latency really high to attempt to keep the system stable.  Depending on the system and interface that you’re using, you’ll probably have to lower the setting to the point that you get glitching (or max out the memory) and then bring it up a little bit from there.  With the headphone out of the Duet – even with these settings the latency is suprisingly tolerable.

If I click Edit Device – that opens up the Audio-Midi Setup application (or you could find it in the Application – –  > Utilities folder)

Note:  I’ve changed the output format to 88.2.

Going back to the Audio-midi sample rate window – it shows:

An Important note about sample rates:

I’ll mention this again – but if you’re going to be incorporating other audio into the session (including looping in SooperLooper) – you’re probably going to have to set the sample rate back to 44.1 (and set the Impulse responses back to 44.1).  If I’m not looping –  I try to set the rate as high as I can, but know that it’s going to have to get bounced down to 44.1 for recording, etc.

While I’m on the preferences Tab I might as well set up recording to the external drive.  Click on the tab marked “Recording”.

Now if I click on the “Rec” button at the bottom of OUTPUT 1 in AU LAB, it will record whatever I do to the Lacie as the default location, in a 24 Bit AIFF format.

With the changes in this part of the tutorial, the AU Lab Input looks like this with some sample input:

You’ll notice that the output is a little off balance.

If you pan it to the left you’ll balance the signal out a little more. Here’s the setting with all the global FX so far.

You may want to save the AU LAB session now, if you haven’t done so already.

In the next session, I’m going to complete the clean channel effects and automate some parameters with the Midi Learn function to be able to make changes to the sounds with the Line 6 Shortboard.

You can find all of the laptop guitar rig posts on the Blueprints tab on the top of the page.  Once on the blueprints page – just scroll down to the Laptop Guitar Rig section.

Setting Up “Testing Environments” Or Multi Layered Tones In AU Lab

One site that I always forget to link to and need to do so now is the Guitar Amp Modeling Blog,  which is just a really tremendous resource.  It’s really inspiring to me to see so many people working on pushing more and more into alternate live and studio approaches to guitar.

A couple of days ago I went to the Speaker Cabinet Impulse section of the forum and found that RedWirez, a company that sells a high end collection of speaker impulses is giving away their impulses from a Marshall 1960A with Celestion G12M 25-watt Greenbacks to celebrate their birthday!  The folder is about 107 MB of impulses that go from 44.1 KhZ – 16 bit to 96 KhZ – 24 bit.

There are 17 different types of mikes used for each IR set AND there are ambient mics to capture the back of the cab at various distances, room and wall mics as well. You can go to the link for that here.

I still have the recabinet set – which at $15 for something like 2000 irs is an amazing bargain as well.

But one thing that comes up in something like this is how do you sort through all those speaker sounds?

My solution is to set up a bunch of instances of LA convolver on multiple busses in AU LAB.

In this way I can set up one bus at a time and mute the other channels to be able to a/b/c everything.

Additionally, you can set up more complex sounds by combining different IR’s.

For example here are the IR’s used in bus 1:

and bus1 is the tone.

Here are the IR’s used in bus 2:

and bus2 is the tone.

Here are the IR’s used in bus 3:

and bus3 is the tone.

And the final tone of all 3 together:

To my ears, this creates a more full bodied sound than any one channel.  Each plug in takes up more processing power – so it may be a balancing act based on resources – but since AU LAB uses so much less CPU than something like Logic, it’s easier to pull off here.

In case you’re interested – here’s the patch the sound is based on:

A quick lick – and a rig du jour update from Ho Chi Minh City

Greetings from the former/current Saigon. (Technically Ho Chi Minh City but many of the locals call it Saigon).  I had hoped to post a couple of blog updates up before I left, but instead was running around checking things for the trip. Now a jet lagged – iced coffee and soon to be bahn mi –  fueled post:

.

1 lick or 2?

So first – here is a lick that works off of the swept pentatonic idea (alternating 3 and 1 note per string ideas) that I explored in the last online lesson (you can find a pdf of that lesson here).  While the online lessons have focused a lot on pentatonics – I wanted to add the tritone to make “the blues scale” and show how this approach could be adapted.  Here is the idea ascending:

.

It’s very scalar – but I added  a couple of points of interest:

1. the little descending turn around allows you to play the basic ascending idea starting on both up and down strokes.

2.  I started on the tritone (if played over E minor) or the b3 (if played over G major) instead of the root.  If you’re playing this over G – think Bluegrass metal ; )

3.  The motion is more diagonally oriented than the strict pentatonic example but is the same basic approach.  I start the lick with my first finger and then shift positions for the D on the 12th fret of the D string and the D on the HighE.

.

Here is an mp3: Lick1

As variation – I took the same concept and applied it in a more positional approach.  Be careful with this stretch!  If it hurts stop immediately!!!

.

.

Here is an mp3: Lick 2

And finally here are the 2 licks played back to back:  backtoback 1

.

Laptop Rig

So I bit the bullet and got an apogee duet.  WOW!  It really has made a stunning difference in resolution and I suspect will help a lot with future mixes I’m working on. With that in mind I wanted to share with the rig I used for the mp3s above.

Here was the basic amp setting I used in Pod Farm 2.0.  This was based on a customtone forum patch called Electric Gypsy.  I just swapped in a tube screamer and bypassed the cab (using the Recabinet impulse responses instead).  One of the big revelations that I found in pod farm is that I could put preamps AFTER the power amp.  Adding that in to the signal chain opened it up a lot.

.

.

I blogged about using impulse responses over the cabs before.  The lie 6 cabs sound good – but to my ears the IR’s add a whole other area of depth.  Here are the IR’s I used – these were from the Modern 1960 4×12 set.  The screen shot is from LA convolver.

.

.

Finally – a screenshot of how it all lays out in AULab.  I just hit the record button in au lab and edited out the noise before and after the take in fission.

.

.

FNH Guitar –> Apogee Duet–>AULAB–>PSP Vintage Warmer–>Pod Farm 2.0–>La Convolver (w. Recabinet IRs)–>Sooperlooper

.

I’m still tweaking things – but I think that soundwise everything is improving a lot from where it was even a month ago.  Once I get an A/B set with the floorboard – I think that the laptop is going to be the rig du jour.

One last note – the macbook has is using 4 gigs of ram and was updated with a 7200 rpm Seagte internal drive. (500 gig from OWC).  My computer accepts a 4gig chip in 1 slot – so I may go up to 6 gigs – but the faster internal drive made a big performance difference in the machine. I’d say you’d really need to have that if you’re going to try to go this route.

* Note – I’ve recently posted more on this topic here which may be of interest to you.

So I’m packing, moving and simultaneously trying to get some stuff ready for the Cha’ak’ab Paaxil Festival in Yucatán, México June 3-5th.  My plan is to leave the amp here and to use a combination of Line 6 gear and a guitar to play the shows.

After playing with Wael Kakish and the Middle Eastern ensemble last night, I was able to open the package I got from Sweetwater and check out my new Line 6 FBV Shortboard Mk II.

The new board is REALLY cool.  It’s solid in it’s construction and small enough to fit in my laptop bag.  After I downloaded the FBV Control software from Line 6.   I tried to set up a SooperLooper session in AU lab.  The concept was to run the AU of SooperLooper in AU Lab and use a midi patchbay to make sure the signal was going from the FBV to the Sooperlooper session.  Here are the patchbay settings.

Had some trouble initially  but once I went into FBV control and reset some of the switches everything worked.

This probably isn’t the smartest series of codes to get everything to work – but it’s working.

The only gripe that I have is that I wish that some additional parameters in SL could be controlled via midi (i.e. 1/2 or double speed or main monitor volume for fades).  It’s easy enough to lean over and hit the keyboard – but it does defeat the purpose of ordering a 15′ USB cable.  The board itself though works like a charm.

I’m in the process of working on sounds on the X3 Live for the show – and tweak PA vs. amp sounds.  One thing I’ve noticed with modeling is that there are at least 4 different scenarios for setting up sounds:

1.  Headphone patches – i.e. practicing or recording

2.  Playing through an amp at low volumes

3.  Playing through an amp at high volumes

4.  Playing through a PA.

You might think that there wasn’t a lot of variance – but the differences between these parameters are huge.  I have patches that sound mediocre at low volumes and sound really good when the volume gets goosed a bit.  Headphone patches that work well at home and fall apart live – and vice versa.

As a result of all of these constant parameters I’ve been experimenting with Impulse Responses in Logic’s Space Designer (and LA Convoluter) and getting some encouraging results.

Impulse Responses (IRs)

In a simplified definition:  Impulse Responses (IRs) are measurements of acoustic spaces that can be loaded into applications (Like Altiverb or Space Designer) to create different types of reverberations.

I read an article about beefing up Logic 8’s guitar amp pro by replacing the speaker sims with IR’s.  That article is here.  This got me looking for all kinds of IR’s.  For those of you who want to see how this works on guitar tracks – check out the recabinet site.  There’s a really cool pdf that talks about the different IRs and the mics used to capture them.  As of this writing they’re selling a download of something like 2000 IR’s for $15 bucks.

Now I’ve been testing these at home – the difference is night and day!

It’s late while I’m posting this – but let me give you 2 simple examples.  First here is a simple rock rhythm with a plexi type setting.  This is just the AU recording of the pod with a plexi setting and the 4×12 cabinets selected.

DirtyrhythmnoIR

Now here is a another take of the same pattern and settings but with a 4×12 IR added. It’s a little brighter but the response is different as well.

DirthrhythmIR

To my ears – the second is a little more natural sounding particularly on the ascending chords.  Here’s one more example with a clean tone.  It’s subtle but noticable.  First with no IR

BluevelvetnoIR

And with the same IR as above added:

BlueVelvetIR

The non traditional guitar sounds have various degrees of success, some sound better some sound worse.  But this made a HUGE difference on the headphones.  I’ll try them through speakers later.

For those of you looking for free links here are a couple of them.  I’m in the process of downloading these myself – so no guarantees for the sounds themselves.

First some very cool non-guitar specific responses here:

Then some more guitar and bass specific IRs here. But I’m digging the redcabi.net IRs so far…

I found an AU ( LAConvolver ) that supports IRs and runs in AU lab – if I keep the wet gain at 50% it works well.

The advantages of AU lab are several (including low CPU use and that you can route audio OR midi through it) but the main advantage is that when you save the session all of the parameters in all associated plug-in’s applications are saved.  In other words – when I get it set up for use with a PA – it’s done.  No more re-inventing the wheel.  This is particularly helpful when you’ve set up a series of midi commands for Sooper Looper.

Here’s the laptop setup:

FNH Guitar -> Radial Dragster ->Pod x3 Live -> (Stereo out) ->Behringer FCA 202 (I hope to sub this out with an Apogee Duet eventually) -> Macbook Pro (Intel Core 2 Duo 2.4 Ghz – older model) ->Aulab running LAConvolver and Sooperlooper->(Stereo out) ->Behringer.

Here’s the AuLab set up – I’ve put SL on a Bus – but I since I can mix wet and Dry in SL I could have just left it on channel 1.


Here are some sample LA Convolver settings (these are both from the 4×12 greenback IR’s in redcabi.net):

And finally 4 instances of SL.

I’m still experimenting but this is the current plan.  Now to apply all of this to mainstage to get synths and percussion in the mix….

This may not make any sense.  The goal to to fit everything into 1 bag – except for a guitar and a gig bag.  Hopefully I’ll have photos soon.

Also the title of this references the passing of Ronnie James Dio.  I enjoyed his work with Rainbow and while he and Vivian Campbell had a pretty miserable falling out – their 1st 2 cds had some great moments vocal and guitar (particularly Last in Line with perhaps the quintessential heavy metal guitar solo).  Dio was 67 on hitting the stage with Black Sabbath (ok fine – Heaven and Hell) at an age many people are bed ridden.  It reminds me of my favorite quote on retirement ever:

“All I do is play music and golf.  What do you want me to retire from?” – Willie Nelson

Rest in peace Ronnie.
