I always had problems with crashing, and more so with timing sync (arps, LFOs etc) to MIDI clock with the TI in Digital Performer. I stopped trying and just use the hardware (which is an awesome sounding synth!).
Just for fun I have recently tried the latest few versions of the TI plugin (AU). Having this plugin installed just crashes DP (8) on startup when it examines it.
I sure wish there was a stand-alone editor like the Virus Control plugin but that you didn't have to use as a plugin. It is such a great interface to set up multis and tweak patches. Does it work on anything other than Logic (does it work in Logic even?)
Been a big disappointment and huge time sucker ever since it's inception. Which is a shame as it is a greta idea, and the synth is fantastic.
