Short answer, no.
Long answer:
The miniwave uses a DAC0800LCN. Full scale error is +-1 Least SignificantBit and nonlinearity is 0.19%. Justlooking at the nonlinearity, 0.19% of 10 volts, or the full scale Miniwaveoutput, is 19 millivolts. 1 volt =1 octave, 1 semitone = 1/12 = 83 millivolts, and 1 cent = 83mV/100 = .83mV. 19mV/.83mV = 22.9 cents. So that’s the accuracy you canexpect from the Miniwave. You mayget better results, but that’s not guaranteed.
Pitch discrimination varies on thecontext. For monophonic lines youmay only be able to discern 3-8 cents of pitch resolution. For chords, where you can hear thebeating of the harmonies, pitch discrimination can be better than 1 cent,particularly if you’re using a just tuning. For equal temperament, 1-2 cent accuracyis adequate.
As a comparison, the MOTM-300 VCOpublished specs correlate to a pitch accuracy of better than 1.4 cents from 50Hz to 1600 Hz, and better than 4.4 cents from 25 Hz to 6400 Hz.

Subject: [motm] Quantizing
Another thing I worry about (thought I don't have a miniwave) is the
relative low resolution of the 8-bit setup in theminiwave... is 255
levels enough to quanitize accurately, in achromatic way? Or is it
just better for octave-octave-octave stuff? Just curious what your
experiences are, and, of course, if there are any"official" plans
for a quantizer. I agree that using a MVjust for quantizing is
probably a waste.
