The Roland's (at least, the E and G-series) always have a front panel button for this function (and an FC-7 and Footswitch choice for E80/G70). For those of us that play in Pianostyle Mode, this is one of the more important buttons to have easy access to, yet alone it's general use.

The G70, BTW, has front panel buttons for transpose... no sub-menus there.
