I'm sure you are very set in youre way of triggering fills and variations, but I have to admit - it was no trouble adapting to using my left hand to trigger during performances. The buttons are so close to the keybad, and it only takes a split second to reach up ...... I only use 2 foot pedals. One for sustain, and one for vocal harmony on/off.

Give it a try and see if you can save yourself some setup time, expense, and bulk to carry!
