WMD - Multimode Envelope Expansion

The WMD - Multimode Envelope Expansion is an expansion to the precise, digitally-controlled envelope that is based on the ADSR envelope, one of the oldest concepts in analog synthesizers. However, WMD added more mdoes, more control and more punctuality to it.

Functions that will expand the Multimode Envelope:

Voltage control of Attack-, Decay- and Release times and the sustain level. the CV inputs ahev bipolar attenuators. In full clockwise position one volt at the CV input will double the rate of the segment.

End-Of-Attack, End-Of-Decay, End-Of-Sustain and End-Of-Release outputs give a pulse signal after finishing the according segment.

Retrigger input: sets a fired envelope back to zero and retriggers it.

any signal at the hold input will pause or freeze the envelope.

ADR-Timescale: CV input for simultaneous control of the Attack-, Decay- and Release parameter. This input tracks 1V/octave over approximately 2 octaves.

The Reset-On-Gate switch determines it the Multimoe Envelope will be reset when receiving a gate as long as its output it above 0V

Four LEDs show intesity of each envelope segment. The expansion module needs to be connected to the Multimode Envelope with a 20-pin ribbon cable.
