Try aseqdump and see what kind of velocities you get when applying
various pressure to your keys.

You first need to find the alsa MIDI port number of name of your
keyboard (example form my box):
$ aconnect -io
client 20: 'LPD8' [type=kernel]
    0 'LPD8 MIDI 1     '

$ aseqdump -p 20
$ aseqdump -p "LPD8"
Waiting for data. Press Ctrl+C to end.
Source  Event                  Ch  Data
 20:0   Note on                 0, note 43, velocity 104
 20:0   Note off                0, note 43, velocity 127

Another tool which, among other things, can be used for adjusting
curves is mididings:

Information about how to use it to set your curves is here:
