hebele The very cheap pedal that came with my FP-30X kit only send on/off. I went on eBay and bought a Roland DP-10 pedal, and voila, I have continous partial pedal!
I am also using Pianoteq, on a Mac. It‘s such a game changer. The built-in sampled sound in the FP-30X feels like it (to my untrained ear) mostly just changes volume with different dynamics. With Pianoteq, the change in color and timber is so clear even between mp and mf. That makes practicing fine control of dynamics and phrasing much more challenging and rewarding.
Another thing I found out with Pianoteq is the velocity curve. My FP-30X can only send MIDI value 108 (out of 127) no matter how hard I hit the keys. That means a linear velocity curve can’t produce ff, and also makes the piano sound quieter overall, which in turn makes me press the keys harder. Once I set up a custom velocity curve, the keys feels more sensitive, and not as heavy as before.
