Module description

A Voltage Controlled Envelope Generator based on the CEM 3310 chip. The most versatile envelope generator published to date. An essential unit for experimental sound synthesis and the creation of realistic sound contours.

Manual control of A, D, S and R functions. Single input (TC) for simultaneous control of the A, D and R parameters. Two inverters with attenuators to allow bending of envelope contours and other novel modes of operation. Built-in timer for delay and re-triggering. Independent gate and trigger inputs. Manual gating button also available.
