I've been working on g2ools on and off since the 1.5 release. I've made many changes and improvements:

- Fixed a large number of bugs in the nm2g2 converter.

- There are several new utilities as well.

- I've decoded the USB protocol somewhat and have created a utility to load and store patches on the g2.

- Added support for the older 2.10 patch version of the nord modular 1 to the converter as well.

- A new ascii file format ".g2" was created that allows modules to be
defined in groups. It is hoped that this will replace the current python library for the nm2g2 and allow replacement of existing python code for creating convertion models. Plus, I would like to create a utility to replace modules in .pch2 files from another tool. My hope is to allow new (better sounding, lower resource usage, different implementations, etc.) modules like oscillators, filters, lfo's, and other module types to be replaced in existing .pch2 files. It can also be used to create new patches using a tool g2topch2.py. I have a sister tool pch2tog2.py that creates a .g2 file from a .pch2 file, but it's not complete. There is alot of work to be done to make them usable but it's well on it's way.

I don't quite know when I'll release a g2ools-2.0 version because my time is limited. The source reposity is hosted at:

http://github.com/msg/g2ools

Which I put changes at. It has a wiki and issue tracker for reporting bugs. I haven't updated those sections with much as I prefer to spend my time on g2ools. But I push my changes to it around once a week. github allows you to download a .tar or .zip of the repository (with the "Download Source" button). The exexcuable programs are included and run the same as the current g2ools-1.5 release.

Keep in mind this is still a work in progress. If you want to contribute, you can contact me and will discuss it.

On another note, I'm still looking at the convertion from NordLead 2 patches to the g2. I've found synthpatchconv one sourceforge.net by Ken Martinez. Currently, his code converts nl2 sysex messages to xml and then converts the xml to .pch files. I'm looking at the code to see what I can use for a .pch2 converter.

3phase also requested (I haven't forgotten) a utility to merge 2 variations from a g2 patch into a single variation using a morph. This would be useful for live play and provide the ability to switch from one variation to another without the skip in other parameters. I've thought about this and because you can only have 25 parameters used in a morph there must be a way to determine which ones to choose.

Sorry for the brain dump, I just want you guys (and girls) to know I been working on this since the release of g2ools-1.5.

Oh yeah, one request I would like to make is the "nm2g2 converter" section of the forum be changed to "g2ools utilities" because it's more then just a converter and it would be nice to have other discussion there. Can we do that?

Thanks,
q

Changed it ... any chance you'll post some info about the communications protocol? I'd be interested!

Here is the startup sequence of my g2x. The "Bo" lines are bulk transfers to the g2. The "Ii" lines are the usb interrupt reads from the g2. And The "Bi" are bulk transfers from the g2.

What I had to do to get these was to run Windows in VirtuabBox from within linux and use a program called usbmon. I can capture all the transfers to and from the g2. I've written some python scripts to decode the message into the format of the file I attached.

If you grab g2ools from gitweb from the link above, the program is called g2ctl.py. It requires libusb and the python libusb module. There may be a port of libusb and the python module to mac osx. Since my primary platform is linux, that was the simplest way to develop the tool.
As for windows, I'm not sure you could install libusb as it's a driver level application. That requires signed drivers which I doubt would or could be done with an opensource application.

Hi There Smile,
hope everything is going well..

cool that you still working on it.. I just have my G2 and NM1 running together again.. so if there is something to check..let me know...

Also cool that you still have my request in mind.. there was a similar tool for the NM1 .. and actually i liked it..

i dont know how the sorting was arranged there.. but the programmer of the Nm1 tool well might be still on the forum?

However.. just on a quick thaught it would be maybe good if prarameters that have big changes have a priority. To bad that the switches of the G2 never was updated to be able to be morphed...

Its actually bad that clavia hasnt fixed this one....

but ok..somebody that wants to have morphs maybe have to replace involved switches with crossfader arrangements first

However.. if its only me that think such a feature is interesting you shouldnt bother too much.. sometimes an easy but imperfect implemetaion is allready a good tool to achive nice fx.. maybe dont really have to work on any patch..

best regards
sven

qfingers,

i have a question. i see the builds page and i downloaded them all. if i replace all the 1.5 files with your updates, it wont run. so i would like to know - if we wanted to use the latest version of g2ools that might correct some 'off' patch-conversions, what files would we replace in the 1.5 version with your latest builds and still have it work correctly.

i am trying to get this 'AnythingBox' patch to sound as good as it does on my Micro. the G2 patch is not quite right - its not as glitchy, low-fi, and raw like the Micro version. that is why i am hoping that the converter might build it differently (more accurately):

I would click the *download* button and get the whole .tar repository. It's pretty much the same as a normal distribution except that it doesn't have a version tag on it. There are over 100 changes all over the place so really you cannot just download a couple of files.

It's fixed. My g2ools version uses a compiled version of getbits()/setbits() that speeds the conversion by a factor between 5 and 10 times the native python code. To compile this requires other OS's (Windows, MAC OSX) which I don't have access to the proper tools to build with.

If you redownload the tar.gz file again, it should be fixed. Let me know if it doesn't work.

Where's the output of the lastest version? I just downloaded it and it ran fine. Are you sure you rn the correct one? Could you run it again but via:
Code:
./nm2g2.py -d AnythingBox.pch

This will provide more debug output. I'm running python 2.6.5. The array module has not changed in any version of python I have used.

As a side note to your patch problems (I read your other post). You could try removing the modulation correction mixers. These are within the same colored modules below the main one. Those are setup to give the correct modulation gain based on tests done by 3phase. Because this patch is random in nature, it may be messing up the sound. It may not fix the problem, but it will decrease the patch process and/or memory load. Just delete the mixers and take the input connection to the mixers and apply them to the actual OSC (filter, etc) module.

3phase and I once talked about the converter able to not add modulation correction mixers in with a command-line option. But it never done. This could allow converted patches that are over 100% to possibly work.

q,

i sincerely appreciate you troubleshooting this over the net. nothing is more frustrating than trying to figure out why a program isn't working on someone else's machine. i can tell you this:

i am ANAL about my mac. it is clean and not cluttered. all the requisite files are installed. to be sure - i re-downloaded Python and it *is* 2.6.5 (but when i do 'which python' it says 2.6). i downloaded (again) the latest tar.gz of g2ools and simply changed the folder name from 'msg-g2ools-fc5f0eb' to 'g2ools-1.5x'. this folder is on my Desktop currently while i troubleshoot, as are 2 NM1 patches (AnythingBox.pch and LFOTest.pch). i then follow these instructions:

* install MacPython 2.6.5
* open Terminal and type: which python

--- mine said this:

Last login: Tue May 11 02:39:07 on ttyp1
Welcome to Darwin!
Hyde:~ Hyde$ which python
/Library/Frameworks/Python.framework/Versions/2.6/bin/python
Hyde:~ Hyde$


* copy the whole path: /Library/Frameworks/Python.framework/Versions/2.6/bin/python

* go to your g2ools-1.5x folder and open the 'nm2g2.py' file WITH IDLE

* change the first line (red text above the '# Copyright (c) 2006,2007 Matt Gerassimoff' to:

#!(your path)

mine looked like:

#!/Library/Frameworks/Python.framework/Versions/2.6/bin/python

* hit 'Apple-S' to Save

* close IDLE

---

* open Terminal and type: cd ~/Desktop/g2ools-1.5x (path to g2ools)

(hit Enter)

and then:

./nm2g2.py (patch name) for each patch you want converted like this:

./nm2g2.py Chaos001.pch (or for a folder it would be like: ./nm2g2.py ~/Desktop/Keepers/*.pch)

mine looked like: cd ~/Desktop/g2ools-1.5x

(and then):

./nm2g2.py ~/Desktop/*.pch (also tried them individually like ./nm2g2.py ~/Desktop/AnythingBox.pch

(hit Enter)


-----

this always works with 1.5. but when i download your latest version - i still get:

Hyde:~/Desktop/g2ools-1.5x Hyde$ ./nm2g2.py -d ~/Desktop/*.pch (hitting enter)
crc no _bits
no _bits
"/Users/Hyde/Desktop/AnythingBox.pch"
"/Users/Hyde/Desktop/LFOTest.pch"
Hyde:~/Desktop/g2ools-1.5x Hyde$


-----

there are quite a few file changes if i compare the guts of 1.5 to 1.5x (latest version). for instance - inside the old 1.5 folder i have:

Posted Image, might have been reduced in size. Click Image to view fullscreen.

and the newest version i have:

Posted Image, might have been reduced in size. Click Image to view fullscreen.

and inside the old g2ools/nord/g2 folder i have:

Posted Image, might have been reduced in size. Click Image to view fullscreen.

and in the newest version it is:

Posted Image, might have been reduced in size. Click Image to view fullscreen.

----

here is a link to the 1.5 version that i have that works flawlessly on my mac:

G2OOLS 1.5

thank you so much for helping. hopefully we can get it figured out.

OK, it worked fine. It's just notifying you that there is no _bits module. There is no error. That is just a message to notify you are not running with the compiled _bits.so module. This just speeds the process. Ignore the message. I can remove the message if it's confusing. It's there for me debugging.

The _bits.so is a compiled python module that allows a much faster conversion. When you take the entire nm1 collection and run the converter on it, it takes about an 1 to 2 hours. With the _bits.so, the whole conversion process is done in around a 1/2 hour. The problem is I cannot compile it for Windows or Mac OSX as I do not have the development tools to build it or the OS's to test it.

q,

you're right, sir! i wasn't even trying them for two reasons - first, when i had just downloaded the new directory and tried to just update some of the files in my old directory i got a similar message and the patches it was creating didn't work. it made them on my Desktop but when I tried to open them in the G2 Editor, it would say that the patch was broken and would not work. so i figured it was creating the same kind of broken patch and i was just deleting them without trying them.

second, in the 1.5 version of g2ools, you could see (in Terminal) all the patches being built. because it would list the modules and such in Terminal. so i was going off that too as the new version does not show you that they are built - just that bits error message. so i figured it was failing because of that too.

excellent work, sir. now if a GUI could be made for q2ools 2.0 or even more accurate conversion, i think alot of us would gladly pay for that software. thank you so much for all your hard work and dedication. it's a shame that Clavia dropped support for our gear. that decision to drop the NM1 and G2 made the G2X Engine the last piece of equipment i will ever buy from this company. they lost a consumer with their built-in obsolescence. i'm sure they lost alot of people.

What is getbits/setbits? Is this a JIT compiler that is different than psyco?

Other patches seem to work though.


What "included" dx7.pch. The only included patch is dx7.pch2. I'm not sure what patch you are referring to.

My bad, the '2' had wrapped to the other side of the screen.

Of course you realize that nm2g2.py only converts nm1 .pch files as it would be pointless to convert .pch2 files. Wink

Hi!

Quote:
I'm still looking at the convertion from NordLead 2 patches to the g2. I've found synthpatchconv one sourceforge.net by Ken Martinez. Currently, his code converts nl2 sysex messages to xml and then converts the xml to .pch files.


Has anyone seen or owned this code to convert nl2 to nm1 .pch ? This option has never been added for the G2ool?

The sourceforge look empty : https://sourceforge.net/projects/synthpatchconv/

Here is the only link where I found a little more info

Question
