CubuSynth ADSR PCB (+Panel/Chip) for ElectricDruid EnvGen8 chip

• size: 10hp

• single Thru-Hole PCB design

• 16 pin power (uses 5V Rail / no onboard regulator)

• GATE and TRIGGER input for retriggering

• MODE CV that allows selection of normal ADSR, Gated looping, or full LFO-style Looping mode

• TIME CV for creative envelope modulation

• LEVEL CV for additional Volume / Velocity input

The ENVGEN8C PCB features its TIME CV which shortens the overall time of the whole envelope. The TIME CV makes an excellent modulation input for either envelope modulation or LFO frequency modulation.

It also adds a PUNCH input which holds the maximum level for a few milliseconds before starting the Decay stage. This is very useful for adding extra punch to short percussive envelopes.
