Yes and no. Absolute JND (just noticieable difference) is around 3 cents 
last I recall. That means two pitches played after each other will sound 
equal if the pitch doesn't differ more than that. However, for pitches 
played together, it's much much less due to the beating. This becomes an 
issue when you detune the voices with the CV dac to, say, one octave 
difference.
