Ok, here's my deal, I want to record synth lines using a mixer going from the sound card out to tape in on mixer, tape out on mixer to sound card in. This way I can record synth lines made in the pc with soft synths and record them back in, so I can record knob movement (cutoff, etc...) in real time, otherwise most stay static and can't have a line with say fm7 with the cutoff going in and out. I hooked up a friends mixer to my pc, and had lots of trouble getting the levels right. Setting the computer and mixer to 0dB output would work, but this is way too much power going to the speakers... and they have to be set to 1 for volume : ). The problem here is that I want the signal going back into the pc from the mixer to be the same level as the signal going from the computer to the mixer> if everything isn't at 0dB the signal going back in will be much less... Is there an easier way to do this? Anyone have a different technique, or a solution for my problem?
