General Info 

The Quadrangle is quad cascading triggered envelope generator with an attenuverted output 
per channel.  Each channel has a gate input, voltage controlled attack and decay/release inputs, 
end of attack and end of cycle trigger outputs, and a mode (AR, Loop and AD) switch.  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 of channel 4 to channel 1.  The SUM output 
allows for longer and more dynamic bipolar envelopes, perfect for interesting modulation. Users 
also have voltage control over 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 its own.
