Okay, why? What is the point of adjusting the master track volume rather than the computer's master volume? And what should the computer's master volume be set to during this process?
the computer's master volume shouldn't come in to play here. how are you plugging in the mic and guitar? do you have a proper audio interface/mixer, or are you using some kind of PC soundcard like a Creative Soundblaster?I think
what the manual might be implying is that if the guitar track is at a lower volume than the vocal track you could lower the volume on the vocal track and then adjust the Master track up so that you hear all tracks louder.
I'm pretty sure that the biggest portion of the problem is that you are trying to use your computer's built in sound rather than a dedicated audio interface.
Are you on a PC or a Mac?
And props for reading the manual before posting...
it's like a hipster commie pinko manifesto. Rambling. Angry. Nearly divorced from all reality; yet strangely compelling with a ring of truth.
