Richard,

Sam is using a US-122. The US-224 is an entirely different beast; control surface etc.

I would be very surprised if it used the same drivers and if '64 bit isn't the problem'.

If there were no issues amongst the US-family with drivers, then TASCAM would not have dropped the US-800 like a hot potato and kept the rest of the line alive for 2+ more years.

TASCAM anagrams into SCAT AM, and SCAM AT. I normally don't go for kicking company names around like they are turds, but in this case, I think it is deserving - though I do not fault them for not having a functioning Vista 64 bit driver.

I DO fault them for not having a usable Win 7 64 bit driver for their US-800. Instead of working on a driver, they fire-sale priced the interface and I was one of the stupid customers that should have known better. Even just using the thing to watch YouTube will disable it once the memory leak gets too big.
