I want to share with you the building of my first (but not last) module for my upcoming synth.
It's called additive VCO and it's based on this project : note.com/solder_state/n/n30b3a8737b1e I'm only adapting it to the AE modular format and to my needs in term of building capabilities.
As you'll see I'm getting ride of the Arduino card and integrating the 328P directly to the board with the minimal needed component, so I can keep it small enough the for the AE modular format. All my work is done with Fusion 360 and you can follow it here: a360.co/3j92FYo
Let me know if you can be interested in having the final gerber file and parts list to make one yourself, I'm open for sharing it when it's done and validated.
Here is some view of the actual status:
Don't mind the male connector for IO instead of female ones, I could not find a suitable model in the Fusion 360 library. Same for the pot which are not in the 3D part.
I have no idea, I dont know grains and if there is some kind of compatibility with the Arduino libraries.
The Mozzi library is really optimized for the Atmega plateform and used some low level function to adress the output quickly enough to generate the sound. So I guess it'll not work on grains but feel free to try
It's interesting, I was not aware of this module. As I see on the wiki page you could probably directly put this additive VCO on the grain module with a few changes in the source code. The main change is not having CV and pot control separatly for all 3 parameters.
