ES16 - Extended ADSR Expanded

Complex Envelope Generator

The ES16 is a complex envelope generator using the four segment envelope normally encountered in keyboard synthesizers. This ADSR however, is designed with extra features such as voltage control of each section, an initial voltage controllable delay time, switchable slopes, and a master voltage control. Each segment may be manually set and voltage controlled, so the module may be used with or without keyboards as a versatile, programmable control voltage generator.

In addition to the normal Attack, Decay, Sustain, and Release segments, an Initial Delay time is included. This allows multiple envelopes to be initiated from a single trigger or gate, delayed with respect to one another.

Ramps for the Attack and Release segments can be switched to either linear or exponential slopes with the three-position switch. In the upper position, the Attack will have an exponential slope. In the middle position, both the Attack and Release will have an exponential slope, and in the lower position, all will have linear slopes.
