Scad, the only thing you're limited by is the capacity of your computer - Cool Edit will take up to 64 tracks. One thing to be aware of when recording more than one track at a time is the difference in recording and playback levels. You cleverly set up individual track levels so they're up where they should be, and you record it without clipping, and then when you play it all back, there's distortion because the levels of the individual tracks are being summed. Some people think it adds about 3 dB per track. So you have to cut back the playback levels to avoid distortion.
