Hi Peter: Yes, on the Tyros you can quickly & easily adjust the volume levels for all parts separately: melody (rt1,2,3), left voice, and auto accompaniment. The mic volume, multipad volume, and song volume can also be adjusted here. All these volume level balances are conveniently located on the main window screen (not in some sub menu) and easily adjusted by physical buttons directly below. Another nice touch about the way Yamaha designed their volume balance feature is that you can QUICKLY get it to pop up any time from ANY other sub menu screen you might be currently in, by just pressing the BALANCE button. Very useful.
