[sdiy] 8bits, 10bits or12bits DAC for a midi2cv converter?

[Mason]

I don't suppose it would be at all possible to PWM or bit-toggle the
DAC at a suitably-high rate to get voltages in between the steps,
given a suitable base accuracy on the DAC?
The idea being you'd trade off being able to do things like audio rate
PWM on the CV in exchange for being able to microtune it.
(akin to the standard zero-order hold idea, and with a filter after
it, obviously)
