In reply to coinneach:
You can use the pan control to direct a track to right or left. If you want it on neither r or l you will need to mute the track.
Do you mean equalise? As in adjust the relative volumes if different frequencies in the mix? A sort of tone control? If so, yes, use the eq built in effect to a vst plug in.
If none of this makes sense it could be because A, I'm not understanding your question properly or B I'm crap at explaining myself.
Let me know if you want more help with it.
