OSC3

musical oscillator trio

Melody machine

OSC3 is a trio of oscillators featuring a distinctly musical control scheme. Standard VCO controls set a "center frequency" for one oscillator, and a spread control detunes the other two up and down.

A logic output follows the "beating" of the detuned oscillators, letting you harness the frequency of the effect in the rest of your patch.

A set of spread control modes give you sounds ranging from tempo-synced choruses to key-locked chords.

The VCO controls are designed for ease of use. Octave selectors let you set the pitch range over a 5 octave span. A built-in quantizer makes it easy to create tonal melodies. With quantization enabled, the coarse tune steps in semitone increments and a counter-clockwise turn of the fine tune brings you to perfect A440 tuning, making it a breeze to tune with external gear.

Phase modulation can be applied to the two detuned oscillators, allowing for vibrato, extraterrestrial audio-rate modulation, and waveshaping by self-patching from the center oscillator output. You can also apply analog voltage control to the level of each detuned oscillator.

A pair of unconventional logic inputs provide opportunities for patching gate sequences directly into the module, freeing up utility modules that would be required to produce the same effects.
