Travis Thatcher shared this sneak preview of the upcoming Voice Of Saturn Synth II:

I’ve implemented 3 of the possible 6 oscillators on this one (though the old sequencer case I used will hold 5). The circuit is based around a schmitt trigger oscillator. Super simple, and easy to make a lot of them. Sorry for the horrible video quality. Just finished it and wanted to get a quick demo done.

Thatcher plans to have circuitboards available sometime this summer.
