I purchased a PCI USB card to see whether it would perform differntly to the USB controller on my motherboard as was suggested by Access somewhere on this forum. The symptoms persist, hung notes and a few pops in the audio.

The conditions to make these bugs are:
1. Stress the PCI buss and CPU around 60% to 80%, it helps if you have a Creamware DSP system, they are notorious PCI hogs.
2. Use any of the USB features of the TI.

I don't get these stuck notes if I have a light project running with very little chance of doing full blown mixdown production.

I am thinking a separated PC for my TI is a workable option. Just feed it midi and treat it like a hardware synth. Send the audio back via analog and have a dedicated screen for Virus Control.
