Topic: Casio Privia PX-130

I am able to have the full range of velocities on my new Casio Privia PX-130 keyboard. I don't know if a non-linear curve would be better.

Velocity = [0, 127; 0, 127]

Re: Casio Privia PX-130

I tried the settings posted by BazC in Korg SP-200 and they sound very good on the PX-130. It seems that playing is much easier and flows better. Great sound.

velocity = [0, 16, 32, 48, 64, 80, 96, 112, 115, 127; 0, 6, 16, 40, 80, 107, 120, 126, 127,127]

It is a smooth "S" curve.

Re: Casio Privia PX-130

Well I think the middle of the curve ideally needs to be about 45 degree to give adequate progressivity.

Also banging on the keyboard does not seem to produce the expected volume so the right part needs to be closer to the top, but we don't want to loose progressivity and attractive harmonics in the middle or ability to play soft. All these objectives are contradictory,  here are some compromises.

Basic non-straight curve:
Velocity = [0, 107, 127; 0, 87, 127]

Very soft:
Velocity = [0, 25, 61, 99, 120, 127; 0, 8, 22, 53, 94, 127]
Very bright (no soft playing):
Velocity = [0, 17, 41, 71, 103, 127; 0, 29, 67, 103, 121, 127]

Closer to a good compromise?
Velocity = [0, 20, 40, 83, 106, 127; 0, 15, 45, 110, 124, 127]

I think Pianoteq should react exponentially to the velocity, then a straight curve might work just fine. The soft curve above tries to do that but loses the rich harmonics and makes the keyboard too soft. So an optional adjustable exponential factor seems like an useful possible addition.

Re: Casio Privia PX-130

I am using the "double hump" posted on the velocity curve software thread, and it seems to work very well with the K1 addon.

Velocity = [0, 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, 104, 112, 120, 127; 0, 5, 11, 21, 32, 43, 53, 59, 64, 69, 75, 85, 96, 107, 116, 123, 127]

Btw, I am using the PX-200, which supposedly had a very similar touch. Every setting is default on the keyboard.
