Envelopes/Function Generators

The Percussion Interface (PI) and PI Expander are a pair of Eurorack modules that generate gates and envelopes from acoustic drums, samplers, drum machines, and virtually any audio source. Converting microphone, instrument, line and modular signals...

Two independent envelopes in one Eurorack module, which are accurate clones of the Minimoog's envelope generators. Each unit can be used as an AD or ADSD envelope. AJH Synth stayed close to the original when designing the envelopes, even the...

In just 6HP two Minimoog circuits are integrated; the transistor noise with three timbres and the glide generator with its unique characteristic. The noise-generating transistors are hand selected and analyzed to ensure that the noise has the same...

The VC ADSR is our take on the classic ADSR: now smaller, more powerful and user friendly. The circuit is based in a dual transistor “Current Mirror” (a voltage controlled integrator) and switching logic.

Module A-140 is an envelope generator, and, since it puts out control voltages, counts as one of the modulation devices in a modular system.  As soon as the gate input receives sufficient voltage, the ADSR generates a variable voltage, changing...
