WMD - Multimode Envelope

The WMD - Multimode Envelope is a 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.

The Multimode Envelope uses an analog integrator core with digital control over positive and negative slopes. This allows for total control over the envelope shape and logic operation. Since the core is analog, the envelope is smooth and stepless, especially important for slow envelopes.

The nature of the core allows for control over its shape through a feedback mechanism, this design also allows for Voltage Control over each segment and for the entire envelope duration.

The 8 HP Multimode Envelope is small and powerful, easy to integrate into any system that needs a powerful envelope generator. Voltage control was left off so that this envelope can be easily fit into an existing modular system. Add voltage control if desired with the 6HP expansion module.
