General MIDI has been around for a long time, and although you don't tend to hear much of it these days, the possibilities for sound creation that doesn't use too much processing power are still there.
The Expert Sleepers General CV module give you direct CV control of the General MIDI sound chip, and the results are quite promising already.
This is a module that we actually saw first at the Superbooth show this year, however as Os has now updated some of the hardware, we thought it would be a good time to get some updates.
