Re: [xl7] External tempo Sync Drift

Wow, that's pretty crazy!  To be honest, the only setting that might have 
anything to do with this in the XL-7, is the Base Tempo (which you already 
know).  So I'd be inclined to think this is a motu problem rather than an 
EMu one.  I know, I know, not what you want to hear, but I honestly can't 
think of anything in the XL-7 that would be causing this.  Are you sure 
you're using a quality MIDI cable?  It's a long shot, but that might be 
causing it (very unlikely though).

When you say that the XL-7 is jumping up or down a BPM or two, how are you 
determining this?  Just by looking at the front panel of the XL-7?  I 
don't think that you should neccesarily go by just that, even with a solid 
clock source, the XL-7's display tends to jump like that when sync'd 
externally.  NOw if you're hearing timing fluctuations, that's a different 
story. 

Are you using the latest drivers for your MIDI interface?  I don't think 
USB MIDI interfaces are inherently bad with timing though.  I use a 
MIDISport 4x4 with no issues what so ever, so it can be done.

as a Digital Performer sequence plays, the tempo on the XL-7 will usually 
start in-sync, then jump a few BPM's higher or lower, then return to sync 
for a few measures. then it might jump 1 BPM higher, stay there for two
measures, and then regain sync. the fluctuations are erratic, and while it 
keeps sync about 80% of the time, that other 20% can really screw up 
arpeggios, delays, and LFO's that are supposed to be tempo-synced.

the problem remains whether an empty sequence plays back (no MIDI data at 
all) or a sequence with 10 MIDI tracks and lots of CC info plays back.
