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. rEalm 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.
