[PD] Looking for a pedal controller

Tue Jun 8 23:54:03 CEST 2010

Nice idea, I didn't realize that. So I went and checked the MIDI 1.0
implementation chart[1] its a cool trick, it gives another byte of
information apparently as stated here[2]:

Pitch Bend    MSB       +          LSB

Always learning...thanks :)
