I don't think anyone has uploaded a setting for the GP300 on this forum, but as there is more talk about these hybrids in the forums, I thought I would add my curve to the list. This curve has worked well for me, since I used the PTQ calibration tool (several times) last year.Velocity = [0, 1, 17, 43, 79, 111, 127; 0, 0, 32, 66, 96, 127, 127]
This should work well with any Casio Hybrid that uses the Bechstein action (I believe the GP400 and GP500 have identical actions to the GP300).
