This probably isn't the answer you are looking for.
If you have a manual then it is null and void
I remember old Ensoniq samplers having a weird way of handling
controllers.
I just tried looking up a manual for this one but only found ones for
sale.. (no scans into PDF format)
There is a remote possibility that there is a way of adjusting the
average velocity output via a button combination maybe even keys pressed
(I have a Roland EP-50 and for example to change the MIDI channel it is
sending.. the MIDI button needs to be pressed and then a key that
corresponds to the right channel.. it does the same thing for sending
program changes and it's a good 4 years older than your keyboard.
If you have a manual I'd be scouring it.
good luck
cheers
