Even with the 1.05 update I am still struggling a little bit to get it to work with my Live/Powerbook setup. I have a stress test live set with several arpeggios and lots of midi control data in the background (like pitch bend and modulation) and that just creates a "midi log jam" in which it sounds like the TI can't keep up with the data being sent to it. It really slows down playing the notes and then all of a sudden it will play a bunch of notes super fast to get back in sync.
Strange thing is that I could have sworn I had things working great Friday night, no 'log jams' to speak of. But then on this weekend things are getting worse again. One interesting thing is that I play the same Live set on my work laptop running windows xp and it plays it back fine. Makes me wonder if there is some 'magic' preference setting that I need to use on the powerbook or in Live so that things are better.
But at least I think I saw a glimpse of "total integreation" working on Friday night, not sure if it was real or a dream, either way it was a beautiful thing
