erm... there is an option to set the midi output and input latency in preferences? I use it... or have I not got your drift?

you are right...just this weekend we synced live with a jomox x-base through an emagic AMT8, with no problems at all, no fluctuations, and indeed, you could compensate for midi delay, worked perfectly

as the originator of the thread i urge you to stay on topic please. this is NOT about latency compensation, its about 'unstable', 'drifting' or 'whacky' midi timing - whatever you call it and has nothing to do with latency, which is constant and can be easily compensated in every other program except ableton live.. but thats a different problem.

i would REALLY like to hear some statement from ableton about the timing problem finally... heck, it's more than 2 years that i'm waiting on a solution!

i've tested on a PC with both an emagic AMT8 and edirol UM880 midi interface...the timing sounded solid enough for my ears, i used drumpatterns to make a good comparisation...did you try another midi interface yet?

yes, i tried both with RME Hammerfall Multiface and Midiman Midisport 2x2 USB - makes no difference.

have you tried increasing your soundcard buffer (latency)? in my case the unstable midi timing gets more noticable with increased latency, e.g. at < 5ms its hardly noticable but unfortunatly i cant stay that low permanently as i'm getting audio dropouts.

you are talking about sync latency. This is adjustable. We are mostly talking about MIDI trigger latency

okay sorry. Maybe I should start my own post about trigger latency.

Although unstable sync is bothersome to us also.

i will try, for my understanding: is the trouble in the midi sync (with midi clock) or in midi note triggering?

still nothing on this. hm.

didn't read the whole topic but i seem to have the same problem here.
it seems the more cpu is used, the clock is getting more and more unstable. when i sync my esx to live, the drums on the esx seem to be shifted back and forth out of the grid. :/
so on 1% cpu usage the clock runs smooth without problems but if i increase the cpu usage to 80% the esx shuffles extremely. what the heck?!
tried it with pattern and song mode, no difference...
