The ADSR from Synthrotek is a fully featured ADSR module in only 4HP. It contains sliders for the attack, decay, sustain, and release amounts, as well as switches for exponential or linear shape response. It has another switch for ADSR mode or AR mode, for sustained or transient envelopes. It self cycles when nothing is patched into the Gate input. The Sliders have LED monitoring for each stage, providing clear feedback on the position of the envelope. The Release stage is voltage controllable when in AR mode, as well as all stages besides Sustain when in ADSR mode.
