A small form-factor ADSR envelope generator inspired by the Korg MS-20 EG2 envelope generator. This module supports legato and retrigger modes for the hold time, normal or “Fast” Attack shapes and the optional linking of Decay time to Release time, supports options for the mid-point of the time controls from the “options” cog-wheel button and defaults the Gate In to the I/O Panel Gate if no jack is connected, for simpler patching.
