Can you comment on your statement above, if the drive is capable of micro speed stability would it not be able to maintain its
speed or for that matter a stationary dot on a wall over a 1.8 sec
period?
the speed almost does not matter within a range. our ears and brains are dramatically more sensitive to steadyness of pitch than the actual pitch. and our reality check with our senses is any sort of grain or warbling in a decay or sustain is immediately sensed as a non-linearity......not real.
so the idea of accuracy is going down the wrong path. we want steady.......and we want continuous.
are there people with perfect pitch. maybe, but not many. and different pitches typically don't sound 'wrong'. OTOH everyone can hear when a piano or horn sounds sour and it's a bummer.
there is more to music than these concepts;; but when done right this is very big.
