Subjective tests are not proof.  Mac MIDI programs such as Professional
Performer uses a resolution of hundreds of units per quarter note.  By
setting the tempo to a slow 60 beats per minute, (assuming a quarter
note per beat), it easily achieves a resolution greater than 3ms
between events.  If the Amiga, as rumored, has trouble time stamping
events with no greater resolution than 20ms, than it's accuracy
would be seriously impaired.  Small difference in timing have a
HUGE different on the feel and interpretation of recorded passages.  Just
because one Jazz player didn't notice anything amiss doesn't mean someone
playing another style of music wouldn't be bothered.  

Unfortunately, the journalists who made these accusations did not
fully explain the technical nature of the supposed problem.  Looking
at the turmoir that oversite has caused, it was very unprofessional
of them to put rumors into national publications.  I do not own
an Amiga, and cannot confirm or deny what was printed, only that
it WAS printed, and distributed over the entire United States.
