Digital potentiometers/DAC

A couple of questions:

1. Does anyone have any experience that they can share driving the FV-1 pot inputs using digital potentiometers or DACs? Is there a recommended method?

2. Is the internal 9-bit quantisation of the pot inputs a simple Vdd/512 formula (with hysteresis around these values)?

1. Never tried it so no suggestions but should work.

2. The DAC is actually a few more bits which are used internally to filter out any jitter and provide a stable value.
