Dual ADSR EG

Two MFOS ADSR envelope circuit boards here. I do have a daughterboard to convert the 0 to +10 output to a -10 to +10 output with 0 in the center (white "LEVEL" knobs).

Gate and Trigger inputs can be linked together with a switch, usually so a single gate/trigger source can drive a VCF and a VCA simultaneously.
