I have a piano and am disabled -- wheelchair kind of disabled: I can move my feet but not use the pedals. That task is kind of complicated.

I've considered buying some kind of a car hand-control like [this](http://i.ebayimg.com/images/i/131481763029-0-1/s-l1000.jpg), but I'm not sure if it works, and if I want to use the sustain pedal, it means I have to keep holding the controller, leaving only one hand to play music.

Are there tools or ways to solve that problem?
