Another 'Frankenstein' approach is to find an old keyboard and throw it on the floor.
Then your foot can simply tap the Space Bar key to start/stop RB Jukebox (as opposed to how Darren overcame it). Rip the other keys out of said keyboard to make it even easier for your foot, if needed.

/thinkin' outside the box
//I admit, it's an ugly foot pedal, but has worked
///or so I've heard .. of course I would never try such a thing <wink>
////Again, I'd create the SEQ files in RB and use PT for live performance, if it were me, for various reasons


Make your sound your own!
