Pulse generator PCB
Turns standard gate signals (+5V to +15V) into the typical pulse (+10V pulse followed by a +5V gate) required for proper sustained/transient envelope behaviour.
It is based on the pulse generator circuit used by Dave Brown for the 218r rev2 pulse modification.


CV 1 to 1.2V/oct PCB
Scales 1V/oct CV to 1.2V/oct and features a switchable offset to turn bipolar -5V/+5V CV into positive 0V/+12V.


CV 1.2 to 1V/oct PCB
Scales 1.2V/oct CV to 1V/oct.
