I can't for the life of me figure out what the problem here is...
We have several analog drum machines (TR-707, Oberheim DMX) & synths (Juno60, Nord Lead 3) MIDI sequenced via Ableton Live, using a 5 channel MOTU midi interface.
When running on an older MacBook w/ OSX 10.4, everything runs perfectly.
I recently bought a new MacBook Pro, w Mountain Lion OSX 10.8.2 and installed the newest version of Ableton Live (8.3.1) and now things are all weird.
I'm getting a lot of 'sticking notes' when there's a bunch happening at the same time.. It can handle the drums pretty well, occasional double hits here and there. But the synth bass-lines are just gobbledygook!
There are also some midi-clocked features on some patches that are just not clocking correctly... SO ANNOYING!
is this a driver problem? I have the newest MOTU midi driver installed. hmmmm.
