Pittsburgh Envelope Effects Bob's Signature Etherwave Theremin is

Bob's Signature Etherwave Theremin is of the same high quality as his early designs from the '50's and '60's

OUT - Modulated signal output

to form a 'chord' (available at outs 2 and 3) when used with multiple 1V/OCT VCOs

AMS 15-80 (with Pitch board) and Publison DHM 89 can be achieved

Mute (jack and switch) - A Gate signal more than 3V will stop any more pulses from starting + all pulses that have already started will end normally

Pittsburgh Envelope Effects Bob's Signature Etherwave Theremin isThe 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 .
