Pretty confident we do these things. To protect your rights, we need a diode matrix to select segments from each step. Could add a global/master pitch control/modulation function with a diode to U2-3 Glide In - ~27K to U3-8? No, transistors maybe activate? Outs: Clock Out - Diode from rotary pin 13? CV Out - Diode from rotary pin 13 main synth_tools/3D Printing/Pot_Knobs/Pot Knob in Two.
