This is GREAT PSR2000/2100 news, as 2 pedals imho is simply NOT enough as I've grown to require utilizing 3 footpedals on my Tyros, assigning the left pedal to 'fill to self', center pedal to 'vocal harmonzer on/off', and right pedal to 'sustain'.
Unfortunately, I couldn't find a pic of the midi sustain pedal on the
http://tomscarff.tripod.com website you provided. What exactly does the midi sustain pedal look like? Is it the standard piano damper pedal variety, or does it look more like a raised footswitch?
Larry (Beaky): Would it be possible for you to take a pic of it and post it on the web?
