ScalaG2

seanwayland

Hi there all ,
I want to remap the notes of my G2 . Ideally I could save different "scales" as patches and change between them. I can do it with " midi patchbay" , but it is crude and requires me to bring my computer to the gig . It would be great to do it on the nord . I installed the "scala" and was impressed. Excellent work . I dont really want to detune each note microtonally . I want to want notes " all over the place " to my specification .

"
I was just informed by Manuel Op De Coul, the author of Scala, that there is another type of Scala file, ".kbm", which specifies the keyboard mapping. This helps explain why the .scl files do not specify a mapping at all. My G2X keyboard doesn't even go below MIDI Note Number 12 (C which is 4 octaves below middle C), unless I am mistaken. Perhaps modifying scalaG2.py to take a .kbm file as an argument might address the usability vs. resource issue? Then we can avoid the problem of resources being unnecessarily wasted on the tuning block. As always, thank you for your efforts! "

This is posted below . Ideally I would like to be able to convert a midi file ( with my scale ) to be played over the entire keyboard . Please reply thanks .

thanks ian ,
I will look into it . I am Australian. What's with the wonbat ? Where's the kiwi ?

Hi.

I've been trying to create a G2 patch file that will play a scala tuning file in the hope that I can play scales on the G2 with unusual tuning, but I am having no luck in trying to make it work. Here's what I have tried:

The G2SCL.pch2, scalaG2.py and nm2g2.py files are inside the G2ools-1.5 folder, which is located in the Applications folder of my Macintosh HD.

If the scala file I'm trying to convert is called "Test.scl" and I open a Terminal window and type:

./scalaG2.py Test.scl

I get the response:

No such file or directory

I've never used Python files or Scala files or even the Terminal window for that matter, so this is all quite complex to me.

Can anyone help with this?

Ok, not to worry (for now). I think I've worked it out and appear to have converted my first file. Haven't tried it on the Nord yet.

The problem was that I hadn't located the g2ools-1.5 folder from the Terminal window. Once I was in the folder I typed the same command prompt and a new .pch2 file was made created.

Hi!

I try this too with no luck. This is what I do:

-windows XP PRO x84
-python-3.3.2
-g2ools-1.5

1. put the "scalaG2.py", "G2SCL.pch2", and "pythagorean.scl" in the g2ools-1.5 folder
2. open a shell (cmd)
3. located the g2ools-1.5 folder from the Terminal windows (cd C:\.....)
4. in the shell I write : scalaG2.py pythagorean.scl

After, I got this message :

"File "F:\...\G2\g2ools-1.5\scalaG2.py", line 62
print head
^
SyntaxError: invalid syntax"

Is it because I use python-3.3.2 ?

Thanks you for your help

Can I use the Scala G2 tool patch (.phc2) for interbus slot patching ? Control the pitch on a synth to another slot ?

Not working with a "NoteSend" module linked to another slot. I tried this too :

Slot1
The output cable from the Mix1-1A1 in a new "2 outputs" module (Left In) and the gate from the "Keyboard1" module in the "2 outputs" module (Right In). I select BUS 3/4 on the "2 outputs" module.

Slot2
On the synth slot I create a new "2 Inputs" module. Select Bus 3/4. Left side go to "pitch oscilator in" and right side go to the envelope AMP gate.

The pitch move like a lfo or legato mode when I play keyboard. Can I have to convert the signal before to connect it in the OSC pitch input ?

EDIT : I cleaned the patch above to make it clear. I just need a tip to dig to understand the problem. Is it an issue about interslot (DSP) latency that I can fix with a delay? Or an issue about the amplitude from the signal ?

It seems that my problem is related to the polyphony. Because everything work fine in mono.

I want to understand something else. How to increase the resolution :

I was wrong. The pitch is controlled from the Osc1, not from the Osc2. It works.

Now I want to talk about the filter. When using a non-conventional scale (or just by changing the Master Tune in the System setting) the filter is not in harmony with the oscillator pitch.

The Equal Tempered
Chromatic Scale
(where Concert A = 440 Hz)

C4 = 261.63 Hz
C#4 = 277.18
D4 = 293.66
D#4 = 311.13
E4 = 329.63
F4 = 349.23
F#4 = 369.99
G4 = 392.00
G#4 = 415.30
A4 = 440.00
A#4 = 466.16
B4 = 493.88

The filter values (Hz) from C4 to B4 :

261.6, 277.2, 293.7, 311.1, 329.6, 349.2, 370, 392, 415.3, 440, 466.2, 493.9

Now when I use another scale, the filter stay in the Tempered Chromatic Scale

But... With the G2SCL.pch2 I can build a a filter that is representative of the scale I use. I patch a pitch control signal into the FM input from a "Ftl Nord" module. Next, I insert a "Constant Value" module and I patch the 1st cable from the "LevAdd2" module into the "Constant Value" module. To fix each step to the right Hertz into the "Sequencer Controlled" module, I use a white noise module before the filter (with a BR filter type). Like this I can recreate a sine. It's easy to fix all steps to the good Hertz.

My filter is in harmony with the pitch of the scale!

Thank you varice! As you say : "Too bad that not all G2 oscillators modules have an FM input though." Same for the filters!
