Subject description: welcome to the NM2 to Csound project
Reply with quote  Mark this post and the followings unread

Hello folks!

My name is Gleb and I am one of the developers of the PCH2CSD project. Our goal is to create a converter from NM2 patches to Csound code. This should provide a nice way to emulate the NM2 and to give it a new life, incl. patch to vst export and turning some existing open editor into a NM2-like modular synth.

Our project's site is https://github.com/gleb812/pch2csd
Most recent paper on the project progress is here http://csound.com/icsc2017/proceedings/ICSC2017_paper_Rogozinsky.pdf
The github directory also contains some useful info.

Briefly, so far we are able to parse the pch2 and automatically generate the csd file with the corresponding Csound models of NM2 modules. We successfully emulated couple of basic generators, filters and other modules.

Any enthusiasts are VERY WELCOME to take part in our project. Any suggestions, questions, etc are welcome too.

Kind regards,
Gleb

Hi everyone.

Another developer here. Just want to add that we are currently working on the implementation of the NMG2 modules in Csound language. After we have the most modules implemented we will build a free VST instrument that would allow you to play your patches in DAWs by dragging “pch2” files onto the instrument GUI. Moreover, you’d be ableto edit converted patches, thus adding new features and algorithms to your sound.

If you like the idea you can help the project in a number of ways:

* Writing the Csound code. We even can to help you with learning Csound a little bit.
* Analyzing the behavior of the Nord’s modules. E.g. the ADSR here is not a typical exponent, but with some quirks. Or that oscillators start at random phase on each note trigger. Reporting on these quirks will greatly help us to improve simulations.
* Spreading info about the project — that may help us to find people who can help.

We are happy to discuss everything related to this project.

Cheers.

Hi gleb812 and ech!


I quickly explored your project in July 2017. I posted the Github link here. Then I reinterested recently, 2 weeks before the publication of the article (February 12). Are you the authors? I commented on this article in several places because I found that it lacked information.

I admire this project and your motivation! I'm happy to know that you are continuing this adventure in 2018. I noticed the lack of update on the Github link since last July.

Let me know if I can contribute. My Csound knowledge is limited at the moment, I am not too bad with python. In the past I have already studied the tool pch > pch2. AND I love my G2!


I do not know if it can help you but lately I posted 2 useful links concerning the technical details of the G2 and a topic for the module bugs and undocumented specs for each modules. I will continue to update this document.

Thank you for this post that gives an idea of the bright future of this project.

Hi Blue Hell and Wave! Thanks for your greetings.

Wave, I've sent you a PM with my contacts. I am sure there are lots of things to do, so your help is much appreciated.

If someone would like to take part, please just let me know.
