...i would first find a drum machine, or kbd with midi clock out and try syncing with that....at least you could then eliminate the xl7 as being the problem. then, i would try using the mtp without the hub, and if that fails, try another cheap midi interface. those motu boxes can be a pain, and may be the culprit. deknow --- In xl7@yahoogroups.com, "wildstar_1701" <justinsamaha@y...> wrote: > hi folks. i could really use some help on this one, as it's grinding > my work to a > halt. problem summary: my XL-7's tempo drifts in relation to an > external > master tempo clock. yes, i have Base Tempo set to "ext". the XL-7 is > connected to a MOTU micro lite, connected via USB to my Mac G4, > running > Digital Performer 4.1 on OS 10.2.8. > > 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. > > i've checked, re-checked, and re-re-checked my Digital Performer sync > settings, and of course the XL-7's Base Tempo setting. maybe it's > the MOTU > interface? maybe it's USB? i've heard strange rumors about MIDI and > USB not > getting along well. maybe it's that my MIDI interface is plugged into > a USB > hub? > > i've tried searching the archive here, but haven't found anything > like this > problem. if anyone could direct me to a thread here that i've missed, > or of > anyone has some insight into this problem, you would have my eternal > gratitude. my hunch is that either i don't have DP's "transmit sync" settings > right (even though i THINK i do), or that there is a problem with USB or my > MIDI interface. > > thanks!
