A simple one channel envelope generator with exponential attack and decay, sustain option, and looping capability
Inputs and Outputs:
- digital in: trigger an envelope
- analog in: added to knob 2 to determine fall time
- button 1: change sustain mode between AR (Attack Release) and ASR (Attack Sustain Release)
- button 2: change looping mode between Once and Loop (Loop mode overrides sustain mode to AR)
- knob 1: rise time
- knob 2: fall time
- cv 1: a copy of the digital input
- cv 2: the generated envelope
- cv 3: the inversion of the generated envelope
