Envelope Generator

Dual-output EG and LFO

The world's most advanced ADSR. Features 3 different EG models: 911 style DADSR/AHDSR, Synthi 100 Trapezoid with quadrature outputs, and our own ADSAR/DASAR we call the Pyramid Blaster. If it's confusing why there are multiple shapes mentioned for each model, it is because this envelope generator outputs two shapes simultaneously!

There are 4 modes of operation: Hold, Trigger, LFO A and LFO B. "Hold" means the envelope will move to the sustain stage and wait until the trigger input returns to 0V to move to the next stage. "Trigger" means the envelope will move through all time stages on a leading edge at the trigger input, "LFO A" means the envelope will free-run in a loop and restart on a leading edge at the trigger input, and "LFO B" means it will loop only while a gate signal is present at the trigger input.

Envelope Generator has 4 different time scales: X.1, X1, X10, and Tempo Sync. The Xn scales are based on the absolute time markings on the front panel dials, 1 second, 10 second, and 100 second ranges. "Sync" will tempo syncronise the stage times to musical values based on tempo information received over the STG Clock Bus connector on the back of the unit.

The stage outputs are gate outputs which last the duration of the stage they represent. Additionally the module supports full voltage control of time, sustain level, and slope curve.
