Dude, Try this company

Im looking at buying their 58 key fully programmable keyboard. you can get a USB or PS2 version. Mine should be here in a couple of weeks. A programmable keypad is the way ahead, especially with all the bells and whistles that are in SSL. Beats farting around on the keyboard short cuts. Too time consuming, too fiddly, and too risky that you might hit the wrong combination of keys and stop the music.
Ill let you know how I get on
