Foot switch(es) or no?

I talked about it here:

Selecting songs live

Other ways I have experienced with (this on macosx): Wii remote (using Bluetooth) + Osculator (app) Roli Control Blocks, namely Live, Loop or Touch ( using Bluetooth) “Something” on the floor? I use an older SoftStep. Anyway, some device that can send MIDI note, MIDI CC or MIDI Program Change.
