Quadrangle

Quad cascading triggered envelope generator

The Quadrangle is quad cascading triggered envelope generator with bipolar output attenuversion. Each channel has voltage control over attack and decay/release, end of attack and end of cycle trigger outputs, and mode (AR, loop and AD). Each channel's EOC is normalled to the next gate input, resulting in interesting rhythmic opportunities. Channel 4 has a "stop" or "continuous looping" switch which allows either a "one shot" cascaded envelope or continuous cycling. The SUM output allows for longer and more dynamic bipolar envelopes perfect for interesting modulation. Users can also voltage control all of the attacks and decay/releases simultaneously when using the ALL A and ALL D/R input jacks. Massive function generation, modulation, rhythm and versatility sets the Quadrangle in a class of it's own.

Features:
-4 Cascading envelope generators
-Attenuverters for each envelope output (dial in that secret sauce!)
-Attack, Decay/Release and Loop modes per channel
-Super fast ~2 mS (Audio Rate) envelopes
-CV over Attack and Decay/Release per channel
-CV over ALL Attack and ALL Decay/Release
-Bipolar Voltage SUM output of all envelopes
-End of Attack & End of Cycle trigger outputs per channel
-Normalled EOC to next channel Gate input (broken when jack is patched)
-One Shot or Continuous Looping of all channels

Please note: If purchasing as a fully-built unit, the Quadrangle has a depth of 15mm; if purchasing a DIY version, it has a depth of 38mm.
