This brings to mind the now discontinued(?)guitar strap on type midi keyboard controlers: the Roland AX1: http://synth.free.fr/030011.php3
& Le Key from a French company called LAG. http://www.harmony-central.com/Newp/WNAMM99/Lag/Le-Key.html

I had seriously considered purchasing one of these at one time, as they're great for walking into the audience. With both wireless mic & midi, this would provide the ultimate in flexibility & portability. The Roland was a bit flashy (bright) for my tastes. Unfortunately the Le Key $1,900 US dollars. Anyone here own or have any experience with these units?
