I have the MD sync'd as the slave to Cubase SX 2.2.  When recording,
the audio is late by anywhere from 350 to 1450 samples.  That's a
pretty high variance.  (If my calculation is correct, at 96KHz and
134bpm, that means it's off by as much as 1/32 note, which is
certainly audible.)  Is there any way to improve this, or is this just
inevitable because of MIDI's lack of precision?  I'm trying to avoid
correcting it all by hand, which is time-consuming.

Just to pre-empt a couple possibilities: the MD can't act as the
master clock to Cubase SX, because it only receives MIDI timecode in,
and the MD only sends MIDI clock (as far as I know).  Also, my
hardware is definitely fast enough to record without disrupting
Cubase's MIDI clock (Athlon64 3000 and a 7200rpm hard drive).

I searched the archives and found basically the same question about a
year ago that was never answered.  Anyone have new insight now?

Cheers,
Dan
