Dual ADSR

Dual ADSR module for +/-15V modular synthesizer, with PCB-mounted potentiometers. Gives two separate ADSR envelope generators, based on YuSynth design: https://yusynth.net

Two independent sets of controls, both can be additionally configured via jumpers for slow (5ms to 10s) and fast (1ms to 1s) times on Attack, Decay and Release. Note: both jumpers should be set uniformly (both slow or both fast) in a single channel. Channels have separate jumpers, so one can be fast and one can be slow.

When switching jack is used for Input 2, it can be wired so that Input 1 is present when no patch cord is inserted into Input 2.
