I'm in the market for some gear to get a small project studio going with intentions on recording other artists.

How do I assign a track to my Mackie Onyx 1220i mixer in Logic Pro 9? I tried choosing under I/O but I only find output 1 and 2 there.

I've run my mac with the Mackie Onyx 1220i for the last two days, and it have worked very well. Then I started Logic Pro 9 and it was very slow. After a restart, the whole machine was still slow. I unplugged the mixer and everything was back to normal. What is wrong?

So I am using a Mackie 1220i hooked up to my PC via firewire to Ableton live.

My question in brief is how do I mutlitrack? Here is more details;

When I select my audio input devices in Ableton I see 8 Mackie drivers:

Mackie CH 1-2, 3-4 and so on.
The Mackie CH 13-14 are Aux sends and 15-16 are master.
Ableton only lets me choose 1 driver at a time.
