Pittsburgh Envelope uni vibe the System 90 Synthesizer is

the System 90 Synthesizer is a 100% eurorack compatible modular synthesizer

technology allows that phase sweep to be driven with triangle (linear)

Turning it clockwise narrows the waveshape into asymmetrical pulses

with the frequency increasing as the knob is turned clockwise

142mA @ +12V

Pittsburgh Envelope uni vibe the System 90 Synthesizer 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 .
