I was just playing with one of those last week on Windows 7 64-bit, and I couldn't get it to work right, either. Then, I tried the original US144 (not MK II), on a customer's Win 7 64-bit system, and it worked, though it glitched if latency was low at all. In this case, the updated product seems to operate worse. Not that the US144 was trouble free on XP. I've only been hearing about their low-end stuff lately. I haven't played with a US2000, for example. The low-end stuff definitely has problems. Certainly there is better for the same money.

Please forgive me for this post, but I'm stumped right now. I'm using a Tascam US122MKII interface with Windows 7 64 bit. I've been using it with no problems with the 32 bit version of Sonar 8.5.3 with the latest CakeTalking scripts. I've been using it with the ASIO drivers and everything's been sounding great. When I installed the 64 bit version of Sonar, I've been getting those pops and clicks that occur when the buffer settings are too low. I tried switching it to a higher buffer with the ASIO drivers, and I've switched to WDM drivers and have upped the buffer there as well and haven't been able to rid myself of those terrible clicks. I've also checked the drivers that I downloaded from Tascam and they are supposedly 64 bit drivers. Does anybody have any ideas why this might be? I'd really love to check out how well Sonar runs in 64 bit, but so far can't really appreciate it as its unusable right now. Thanks a lot for any advice. JustinPLEASE READ THIS FOOTER AT LEAST ONCE!
