I have previously been incredibly frustrated about the TI. It would constantly be out of sync to the point where it was not usable for using with a DAW. I would play it with the keyboard and it would sound great, but even bouncing audio would be so far off in terms of tempo that every little sound would require manual fixing afterwards. I have a fast Mac Pro and follow all guidelines for the setup and it still doesnt work.
I recently accepted that the TI plugin is useless so now I only use it using MIDI cables with the sound coming from the Output 1. There is no more USB cable at all and I'm starting to actually use it in productions now.
