hi recently got mixer,tried recordign mutiple tracks live when we jam but its mixes all 3 into 1 trac when played back,shouldnt it stay in seperate tracks when recording,how do i keep them in seperate channels?

thx in advance,im a newbie to all this.
Read the manual. Most of those mixer/interface combo units only mix down and send the master out to the computer via USB. This is one reason why I never like those type of units.

Onyx makes the Firewire ones which will keep tracks on their own.
