A simple Stretch Tuning module that can also be voltage controlled, allows up to 2 cents/semitone linear stretch (and a small negative stretch) for both a mono and a polyphonic signal. The root note for the stretch can be set (using A4=A440 as the scale) and the stretch can be tied to the note (quantized) or linearly to the 1V/OCT voltage.

Also sold as part of Andrew Macaulay's Performance and MIDI Collection and included in Andrew Macaulay's Ultimate Bundle.
