i initially wrote the program and arduino code to allow adding new pedal data to an existing performance. you can, for example take a performance that had bad pedaling and replace it with better pedaling. i used the hall effect sensor connected to the piano pedal trapwork so it could sense the actual pedal movement for recording. this is the reason for all the calibration stuff in the program. if calibrated correctly, you can remove the original pedal data from the MIDI file and play it on the DKV while recording the new pedal data. since you are using the actual piano pedal, you get immediate feedback of the effect the new pedal data will produce.

The attached screenshot is of the settings I found best, but it depends on the regulation of the piano. On mine, the dampers just clear all of the strings at a midi value of 60 (I created a test file with various levels to ascertain that figure). So I set it at a max of 70 to ensure strings were undamped. At 40 all strings were fully damped. So a range of 40 to 70 minimises the pedal travel. However, the ramps of midi 64 controllers thus created still descend to 0 if time permits, so I\u2019m not quite sure what the pedal off threshold of 40 determines. It does seem to put a shoulder in the ramp at the 40 mark and affects the position of the ramp. This is always a compromise. The sustain pedal will take effect at a later point in time and will come off earlier and I think that the threshold levels are intended to position the ramps so that the sustain actuation occurs as close as possible to where the former on/off controllers occurred. It\u2019s not perfect because damper lift-off is not perfect. On my piano, which is new, the damper lift-off range is about 50 to 60.
The soft pedal is not so critical. For the soft pedal, the ramp is set to run the full range from 0 to 127, as you would expect. I\u2019m again not sure of the significance of the on and off threshold values, but these settings worked for me.
Kind regards
Geoff

Geoff, do you have an idea what would be good starting settings for MPX100II?
This is a mark II DKV, not mark II XG.

i wrote the program but Geoff did the testing and has a DKV to test on so he is the authority for appropriate settings, at least for pianos similar to his.

Wow - this looks like just what the doctor ordered to fix the noisy on/off pedaling issue. Can't wait to test it during day hours. Thanks!

i uploaded the new version of the pedal modifier program do not use the link in the last e-mail because the name has changed. go to the download page of my site spencerserolls.com and find the On Off to Gradual Pedal converter program (New) actually, this link might work from e-mail but best to visit the download page instead.

Geoff, what is the exact name of Spencer's pedal program? I could not find it...
