well I just route the audio out thru my 1010LT , so it won't bleed onto the vocal I'm using.. I don't sing too much.. so switching between modes e.g. asio / mme isn't too bad and I didn't want the hassle of buying a card with decent pre's etc.
although I don't use a standard on board card for all of that.
usb mic's are pretty generic, but having a headset / mic.. hmm the samson is based on a none usb mic.. so using a headset.. well depends on the quality of the mic itself.
the g-track is a very different thing from the samson mics.. if samson wanna send me a g-track, then I'll write a guide..
although you might find better luck with that thing by using asio4all as I did ask if it had native asio drivers, and I'm 70% sure it doesn't.
