Stages by Mutable Instruments clone, built by Paton Audio.
Generate any type of modulation (including complex LFO shapes, sequences, envelopes) by grouping, chaining, looping elementary segments that perform one of three simple functions: ramping between voltages, holding a constant voltage, gliding to a voltage until the next trigger is received.
The module detects the presence of jacks on its gate inputs to group its segments: whether it is configured as a complex 6-stage envelope, or 6 individual envelopes, or 3+3, 2+4... depends simply on how you patch it. Dummy patch cables might come handy!
When used as a multi-segment envelope, a segment activation signal is produced on all secondary outputs - for example to trigger an external event when an ADSR envelope enters its decay, sustain or release stages.
In case more than 6 segments are required, up to six modules can be chained together thanks to a connector at the back of the module.
A segment, or a group of segments, can loop on itself: if the last segment of the envelope is included in the loop, the loop lasts forever. Otherwise, the loop remains active while the gate is high, then continues past the last segment of the loop. These two behaviors allow the creation of self-looping envelopes (LFOs), or the sustain stage of a good old ADSR envelope!
Even when they aren't part of any group and don't receive any gate or trigger signals, individual segments can perform interesting functions: Ramp can loop on itself and turn into an LFO, Hold can delay a CV and Step can slew it.
Now patch a trigger signal: the self-looping Ramp turns into a tempo-synced LFO, the Hold segment becomes a pulse generator, the Step segment a sample-and-hold.
We've been building for many years and make these to last. Properly tested, calibrated and covered by our 1 year warranty.
