modular synths menu
This software attempts to find the frequency with the biggest magnitude in an audio-signal. This frequency is then transformed into a control voltage.
The sampling is performed 100x/second so that's the number of notes played per second it can recognize.
It won't work with e.g. a regular musical track of your favorite artist, it is meant for a single instrument.
The GZD contraption is meant for eurorack modular synthesizers (Doepfer A100 compatible).
The software can be found on GitHub.
