MST Dual AD/ASR Envelope Generator

Dual Envelope Generator

Synthrotek is pleased to offer a complete line of eurorack synthesizer modules, power, cases and accessories in both complete units kits and panels & pcbs. We now offer a very complete analog modular monophonic voice with many accompanying utility modules. This new complete voice is the product of a collaboration with synth guru George Mattson, who now joins us in releasing our new MST (Mattson – Synthrotek) line of premium modules.

The MST Dual Envelope is a simple to use yet complex dual envelope generator. Channels 1 and 2 are both normalled to each other to cycle when the other respective channel hits end of cycle, allowing for really interesting ping-pong effects. Each channel also has an end-of-cycle trigger output with LED indicator. There’s a normal and inverted envelope out. The inverted envelope out can be further modified by the +5 offset switch, which allows the inverted waveform to travel in the positive. The + output level allows the envelope signal to go between zero and the maximum voltage rail. Attenuate the output level down for a more subtle envelope (adjust to taste).
