Did not know if it would be proper to qoute/copy/paste from AccessMusic Forums, however, I read consistant replies to people having issues with VC and their Ti's and AccessMusic Tech Support repeatedly emphasized that TI and Virus Control required FULL BANDWIDTH of USB connection and does not work well if you are using ANY other USB connections for other devices, to include if a motherboard has firewire connections.
Someone had made a point in response to tell Access that they have NI Maschine and other peripherals running at same time with other audio interfaces with no problems ....so apparently, the Ti is a bandwidth hog with tech support stating 99.9% of problems are user's PC configuration. You Ti owners may already know that about the bandwidth but thought to pass it on. It's kind of akin to the new audio interface am considering buying to utilize my firewire 400 on DAW PC--even PreSonus interfaces can act goofy, pops, clicks, if even using an USB wireless mouse and keyboard.
Tech support recommended Ti owners to do a PC system check to see what ELSE may be in-use in path of USB connection and a "Sandra Report" for AVID DAW users.
