STG Soundlabs, the modular manufacturing business of Knobcon founder "Suit &Tie Guy," is now taking orders for their envelope generator, billed as "the world's most advanced ASDR," in both 5U and Eurorack formats.
The module features three different EG models: [Moog] 911 style DADSR/AHDSR, Synthi 100 Trapezoid with quadrature outputs, and STG's own ADSAR/DASAR, called 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 four 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 zero volts 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.
The Envelope Generator has four 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, one-second, ten-second, and 100-second ranges. "Sync" will tempo-sync the stage times to musical values based on tempo information received over the STG Clock Bus connector on the back of the unit.
Additionally the module supports full voltage control of time and sustain level, slope control and cv, and gate outputs for each stage via a sidecar module

Introductory pricing is $250 for the EG alone; $385 for the EG with the sidecar.
