Hi everybody,

I am a wannabe computer dj ;-) To do so, I have bought a serious mixer
(Pioneer DJM-600) which I want to use to mix tracks coming from my
computer's hard disk. To do so I need two soundcards (choice I'm trying
to avoid) or a multichannel one.

I am told that Terratec Phase is a good start: do you agree? Should I
buy Phase 22 or 28?

My real question is: are these cards really multichannel? I need to use
them as they would be two in one: that's to say that I can play two
(say) winamps at once, each one playing on a different output channel
that will enter my mixer separated from the other.
To do this I must be able to instruct one winamp to exit through
"device 1", and the other through "device 2" even if the two of them
are physically on the same card.
Obviously a gamer's audio card can't do this: I can play 2 different
songs on two different winamps, but they exit through the same output
already mixed.
Do these Terratec cards satisfy this need or the multiple outputs they
have are only capable of carring one and only audio stream to different
places?

I hope I have stated the problem clearly, thank you very much.
