Also keep in mind that the Penrose will quantize ANY incoming voltages, just like any other quantizer. You could just as easily input a fixed offset voltage, controlled by a knob, and you'd be able to "play" the offset, which is useful for setting up drones and being able to then transpose those with the offset knob. But the Penrose's ability to user-define scales means that your knob-twists will ONLY fall into the designated pitched programmed into the quantizer.

This ability to "force tuning" is one thing that makes quantizers...especially scale-definable ones...super-useful for generative work.
