Zero latence on audio through USB-1 ?? HAHAHAHAHAHHAHAHAHAHHAHAHAHHAHAHAHAHAH!!
sorry.... couldn't help myself...
To add somthing constructive to this post...
Before you buy that Tascam, do yourself a BIG favor and check out the forum for those, that Tascam has at their web site. Find out if you even have the system specs that'll be able to stand using the 482. Those things seem to be very unfriendly with non Intel chipset motherboards. There's also a .pdf file you can get from their web site, that'll tell you why the Intel chipset is the only one that uses the "Proper" or "True" USB protocols.
Last I checked, Tascam doesn't seem to give a damn about making drivers that will make the 482 more compatable with AMD based systems. If this is what you use, you'll probably have to get a seperate USB card to install in your computer. Tascam also recommends which one's of those use the USB spec. that they want to cram down your throat. ( I found it funny that EVERY USB device I have, worked fine... except for theirs.)
By computer standards, the 428 is getting pretty old. While Tascam won't make drivers that are more compatable with more computers, I believe their USB devices are going to quickly become dinosaurs.
I spent about a week of jumping through Tascam's hoops, trying to make a 428 fully functional on my computer. I took it back for a refund. Looking back on it, I shouldn't have wasted more that a day on it. That's become my attitude with almost all computer hardware. It's just not worth it. There's all kinds of other products out there, that'll plug in or hook up, that work first time out.
For less than a 428 costs, I ended up getting an 'Audiophile 24/96' soundcard, and a '
Doepfer Pocket dial'. Check out the Pocket dial. Continuous rotary knobs on a unit that uses feedback data from applications, beats the crap outta sliders that'll have your application settings jumping all over the place.
