The module can also be optionally set to output a specific pitch / note (useful for triggering drums).

Morphing VCO is a virtual oscillator that can be used as a regular oscillator (that can be mixed with your analog oscillators externally), a sub oscillator, a modulator for FM / ring-mod patches or as an audio-rate modulation for controlling anything else in your patch.
The main pitch of the Morphing VCO is controlled via the Pitch Bus.
The shape of the Morphing VCO (CCW = Square, Middle = Sine, CW = Saw) can be morphed using either the Morph knob or any signal routed to the Morph input via the Routing Matrix.
