So I'm working on a project right now and I'm interested in getting some input on the project as I'd like to open source it when I finish. Its a similar idea to the Nord modular but implemented in PD, Python and C. I will try to keep this up to date as the project continues and if there is interest I would be happy to upload some of the code to git

Parts:
Python GUI for building synthesizer utilizing pyata and tkinter
PD objects for each module(VCO, VCA, ENV, MIX, VCF, MIDI, OUTPUT)
Raspberry Pi Cluster(1 conductor and 4 voices) connected via an ethernet switch a d voices ran through a passive mixer
C program for converting midi to OSC messages and sending them to each voice for polyphony as well as uploading your patch of choice

The main idea is that you build a synthesizer patch in the GUI which runs on the conductor which is converted to a PD patch. This patch is then chosen on the conductor raspberry pi when in play mode and is distributed to the 4 voice raspberry pi. All pi's are connected through a switch. This signal for each voice is sent through a passive 4 channel stereo mixer which is sent to a speaker or headphones. A midi controller is plugged into the conductor via usb and its knobs/sliders can be mapped to slider objects within the patch

Adding Modules:
A module consists of a pd object and a python array that represents the inputs and outputs and generates the module object within the application. This will allow for the simple addition of new modules as long as they adhere to the input and output specifications. I hope to add substantially more modules once I get the minimal set needed to build a basic synthesizer.

Would people be interested in something like this at all?

It does look very interesting. Would like to try it out when you release it.

@jersupereq +1
Do you have example on how it sounds?

@seed Don't think I'll be able to beat the beauty of those modules.

@EEight No sounds yet, still working on the UI, midi implementation and deployment on hardware at the moment. All of the modules are currently relatively basic but I hope to make some more complex oscillators, modulation sources, etc once the infrastructure is complete..

"Why code from scratch when you can adapt, reuse, recycle"

Small update. Things are working for the most part, still doing some debugging of the GUI and working on the distributed aspect running across the Pi's so I wouldn't recommend trying it out and expecting everything to work. The graphics have changed a bit as well. Here is the github repo if anyone is interested in checking it out. The graphics have also changed a bit. I will soon update the needed repos for running it, on the github page.
