Hi! I just finished building a small (eurorack) module prototype and want to see if there's interest outside of my studio...
It's a super simple module which allows me to send OSC over wifi from ipad or pc to my modular. The module has 20 12-bit CV outputs, (in code) switchable from -5 to 5v or 0 to 10V. Since its 12bit, you have 410 steps per octave (on 1V/octave), which should be enough for doing basic microtonal stuff not possible with midi.
It's based on just an ESP8266/NodeMCU (which comes with wifi and is programmable via usb/Arduino ide) and a MAXIM113300 dac/adc. Total of these component should be around 30 euro.
The 113300 also allows you to programmatically switch to use the same 20 ports as adc, so as CV input. Still need to program the switching and OSC output though, but I'll save that for some time later to keep everything simple for now.
If there's enough interest I can put some effort into a write up on how to build such module yourself. Raise your hands, please. Also for the non-DIY I'm thinking of maybe productising the thing (also to fund future module ideas), but I'm not so confident being a software guy doing a hardware product. I'm open for ideas
Still need to tidy up the (Arduino) code, but it will follow shortly...
