Here is the guts of one of the top rows. Toggling the the midi trigger nodes in the mux 8 node will switch between the top output, which has a fixed length, and the bottom output, which has the length of the gate that the clock signal had.
Here’s synth I came up with based upon the work @RobertStyrett did initially. There’s a lot of modulation sources and the patch always creates sound when the output power is toggled on. It has a drone effect. You can play it in MIDI monophonic legato mode. The frequency of the oscillators and the patch in general are changed by setting the frequency with the knob in the module at the top in the middle of the patch. The two sets of 8 buttons are used to generate the waveforms for the modulation sources. Be aware that you may cancel out things depending upon the sequences you choose.
