Yamaha CLP-430

After a lot of testing and calibrations, this velocity curve seems to work fine for me for regular playing (pop music):

Velocity = [0, 11, 24, 33, 42, 50, 59, 67, 77, 86, 93, 102, 111, 127; 0, 4, 9, 18, 30, 42, 53, 65, 76, 89, 99, 110, 119, 127]

Note-Off Velocity = [0, 10, 59, 127; 0, 32, 96, 127]
Sustain Velocity = [0, 10, 72, 117, 127; 0, 0, 64, 127, 127]
Aftertouch Velocity = [0, 127; 0, 0]

Be sure to set the CLP-430's touch to 'Medium' preset.

Cheers!
