This latest beta isn't working for me either
Im on a macbook pro, osx and logic 8 with a motu ultralite.
Ive had a TI since the early days and it's worked like a charm pretty much the whole time.
unfortunately since all the v3.x os updates it has become a lemon with bad syncing/timing/arp issues...some synth lines will start playing off time or just stop outputting while others seem to play ok. it also emits a strange buzz (which sounds like the init patch) every now and then, even when not receiving any midi (ie. the VC plugin is loaded in my project but im not using it) and i need to hit panic on the TI hardware. I also get the "out of sync - press stop and play to resolve" message ALOT, even on an empty project with just one or two channels of TI.
reverting back to trusty old 2.75...think ill wait quite a while to try OS3 (which is a shame as it's got lots of nice new features)
