TexRoadkill is exactly right on each statement. But, I think the manual is very lacking. For example, a BASIC function of any mixer is the ability to adjust the playback loudness levels of existing tracks when you record a new track, right? That is not in the manual. That's total bullshit. The problem is the recording monitor volume of the live overdub is way louder than the playback. This is not good. Why does this happen? Because your playback (on the headphones) of your live recording comes from TWO sources summed, from the track your recording right after the fader PLUS a defaut setting that sends it back through channels 13, 14 (the playback channels). I solved the problem by muting the channels I am recording on and raising the faders to max on the playback channels 13, 14. I never got a straight answer on this on the V-Planet site.
