I use three footswitches with my PSR2100. One is midi activated. I got a piece of linoleum and I attached the footswitches to the linoleum with velcro. Then I taped the cables together. So when I set up, I just grab the linoleum out of my keyboard case. Put the linoleum under the stand, and plug in the three cable ends. With rubber pads under the linoleum, nothing slides around. It works for me.
