Hello all,

I'm project producer and primarily a guitarist from Germany.
Now I own an old Schimmel Piano that i would sampling.

My Problem is that I'm not a good piano player so i can't
play the different velocities (10-12) by my hands.
I'm also an engineer so i will build a machine to play this different velocities.
At this moment i don't know where I am to begin.
Should i build this with weights,springs or motors ?
Have anyone experience with this and can help me ?

For each assistance I would be very grateful.

Regards motte

P.S. Sorry for my bad english
