This operation modifies pedal controllers hold (controller #64) and soft pedal (#67). It maps lower controller values to pedal OFF and higher values to pedal ON.
0 - 63 .................. OFF ............. 0
64 - 127 .................. ON .............. 127
Hint: Duplicated values are removed to reduce the number of pedal controller changes.
Hint: This operation is useful for PianoDisc and Disklavier players which may react with noises when many pedal controllers are used that are not pedal ON/OFF values.
