Pittsburgh Envelope Effects But if you start withThe Pittsburgh Modular Envelope is a complex multi stage envelope generator with voltage controllable rise and fall. Using the sustain switch to toggle between modes, the Envelope functions as either a 2 stage attack decay envelope or a 3 stage attack sustain release envelope. The Envelope response for rise and fall is continually adjustable between logarithmic, linear, and exponential allowing for precision envelope shaping. Cycle times range from .
