VCO-1 – The Oscillator One

This VCO is built on the legendary 3340 IC which has been used in many classic synthesizers such as the Roland SH-101 and the Sequential Prophet 5 amongst others. The IC has been out of production for decades but has now returned and is again available.

This VCO is modeled after the legendary 3340 IC which has been used in many classic synthesizers such as the Roland SH-101 and the Sequential Prophet 5 amongst others. The Oscillator One is built to leverage all functionality this IC has to offer and then some. The Saw shift adds a second saw wave that can be phase-shifted to the original one, as if that’s not enough, a third saw wave can also be added to further spice up the sound. A Linear Ramp waveform has also been added and provides something that has the heart of a square wave but the soul of a saw wave. In total 7 waveforms are outputted simultaneously and offer a wide variety of timbres.
