Hi, I'm Fernando and I have a question related to the X1204 usb mixer. I was reading at the manual ant it says that the user can actually record 4 tracks simultaneously using for that purpose the ALT3-4 outputs, here's what the manual says: " ALT 3-4 OUTPUTS The ALT 3-4 outputs are unbalanced and carry the signals of the channels that you have assigned to this group using the MUTE switch. This can be used to route a subgroup to a further mixing console for example, or or it could be used as a recording output working in tandem with the main output. This means you could record to four tracks simultaneously. The icing on the cake, so to speak, is that you could connect Y-cables to these four outputs and then connect your 8-track recorder in such a way that you have 2 x 4 tracks (e.g. channel 1 feeds track 1 and track 2, etc.). In the first recording pass, you record on tracks 1, 3, 5 and 7 and in the second pass, on tracks 2, 4, 6 and 8." So I plug in my instruments in the 4 inputs and it works right, but now: How can I record those 4 tracks? I mean Which software do I need in order to record the 4 tracks? I'm using Audacity but it doesn't record the four outputs, and I think that's because I can't assign in it the channels I'm using. Then I tried with Garageband but when I got to choose the inputs it shows only 2 (input mono 1 and input mono 2) How can I assign those mute channels that come out of the ALT 3-4 outputs? Later I tried with Digital Performer and I had the same problem. Is there another software that could you recommend in order to accomplish what I want? or could you give me some instructions so I can set up right my software-hardware? Please! Thanks a lot!
