PA800 is a great choice, especially as you don't appear to need a 76 note keyboard to play pianistically on!

One last chance for the E60.... Most of Roland's functions can be triggered with a MIDI command... perhaps a set of MIDI pedals would work?

And in the days of four variations for each style, only ONE footswitch doesn't really give you enough control, so GEM's simple three switch would still be insufficient. Toggling between two variations only takes one switch......
