Pittsburgh Modular - Microvolt 3900


The Microvolt 3900 combines East Coast and West Coast synthesis philosophies in an unprecedented way. Besides standards, the oscillator offers foldable waves. The instrument’s low-pass filter and VCA can act as a low-pass gate. Modulators include an ADSR envelope, a function generator and an LFO with additional random voltage source. On top of that, utility circuits, a noise generator, a MIDI-CV interface and an arpeggiator were implemented. Thanks to 38 patch points, audio signals and control voltages can be routed flexibly.
