The blue cable is sending control voltage that corresponds to the key I'm pressing (1v/octave).
The green cable is sending gate. It's 5v when a key is pressed and 0v when no key is pressed.
These two together control the synth that they're plugged into. pic.twitter.com/g7YLjtMoNS

Thea Flowers writes on Twitter about her custom CircuitPython programmable board working as a USB MIDI to CV/Gate module.
Which means that it’s *reprogrammable* on the fly. There are 6 output jacks on this board. 2 are continuous 0-10v waveforms driven by a 16-bit DAC. 4 are digital 0 or 5v signals driven by a line buffer. You can map those to all sorts of functions.
In my videos I mapped one of the DAC changes to note value. But, you can map it (or the other DAC channel) to output a (low frequency) sine, triangle, square, etc. wave. Or you can make it output a voltage that maps to the modulation wheel from the keyboard.
Or like… A thousand other things. The digital jacks can themselves output square waves, but you can also hook them up to all sorts of events. Like timers. Or when you press a certain note. Or when you turn a certain knob.
She says her goal with the software on this is to write a library that makes the main code.py easy to edit while making music. So if you need to swap out a jack’s function, it doesn’t break you from the experience of making music. So it’ll eventually be this powerful brain for my modular synthesizer.You can read the entire thread and see it in action on Twitter here.
