SidEx is an unfinished but somewhat usable module for controlling the Commodore 64 SID chip by converting CV inputs into MIDI sysex dumps of SID registers 50 times per second.
Currently it only runs on a patched (meaning “unofficial fork” - no pun intended) VCV Rack, but when Rack 2.0 is out, SidEx will be modified to use its official support for sysex messages.
Feedback, ideas and wishes are extremely welcome.
