The Stretch Tuning module allows mono or polyphonic 1V/OCT inputs from keyboards, sequencers, etc. to be “stretched” by up to 2 cents/semitone so that 1 octave is either more than an octave or just smaller than an octave. Some custom tunings (and orchestral tunings) use this to get a more natural feel to the music.

The stretch can be set to be around any “root note” (using A4=A440 as the scale) and the stretch can be tied to the note (quantized) or be completely linear with the 1V/OCT voltage, stretching pitch bends or vibratos.
