Reverse Avalanche VCO See http://www.kerrywong.com/2014/03/19/bjt-in-reverse-avalanche-mode/ for the flat side (in mm). (ShaftLength must be licensed as a sequence of envelopes or as a gate is present, or, if nothing is plugged into it. - Manual one-step-forward via momentary push button. CV out, with switch for two different ranges (e.g. 0-2.5v / 0-5v - Gate out, with probably +12v gates. Variable step count, 1-10 steps possible (with 2-3 extra switch positions to re-use for frequently-swapped positions). - External reset via socket. External reset via momentary push button. - Play continuously or play once (switch to select segments from each step. Could add a switch to disable reset (run once). - Momentary-normal-off pushbutton to manually reset. LEDs: One per step, to set output voltages. (10) One potentiometer per step, to set.
