Topic: How does Range work for MIDI mapping? (RPU-3 sustain pedal problem)
I am trying to expand the range of MIDI values produced by a Roland RPU-3 continuous pedal unit in order to gain half/continuous sustain functionality. Going through my keyboard's auxiliary/expression pedal input, the keyboard only puts out a MIDI range of approximately 0-30 on pedal up/down, rather than the full range of 0-127. I expect this is related to the differences in voltages produced by a volume/expression pedal vs. a continuous pedal controller such as the RPU-3.
How does the "range" function of the MIDI mapping work? The MIDI panel under the options is not really explained at all in the user manual. After mapping a controller a MIDI controller and channel to the sustain function, one is left with changes to the range function, with acceptable input values from -1 to 1. This seems to be a weighting factor of some kind, but after fooling around with it a bit I can't seem to make that control function the way I'd like.
Thanks in advance for the help.
