Hi I am using studio recorder and trying to record both my voice and the system audio of another computer. The computer that has studio recorder on is plugged into a recently purchased audio interface. I cannot seem to get both my voice and computer audio to be picked up by studio recorder. I have only 1 mic preamp and 1 instrument 2 it's called. The only way I can get it to pick up the mac is to plug in the cable into the preamp hole used for the mic. I am wondering if I need a mixer with 2 preamps, 2 mic/line inputs? I can hear both through the headphones but studio recorder only picks up what is plugged into the preamp. The mixer is a Behringer U-Phoria UM2. Any suggestions would be appreciated. Thanks. Regards Janine Sent from my iPad
