I get almost the full 0-127 range out of the pedals, but the problem is
that When a pedal is ca. 80% pressed towards the top of its range, the
MIDI value output is only about 13 (~= 127 * 0.1). The remaining 114
values all seem to reside in the final 20% of the physical pedal range.
It's a bit of a pain to work with since the "useful" values in the
13-127 range are clumped so closely together, and that makes the pedal
seem overly sensitive to me.
I've read in another forum that such behavior is common among new-ish
fcb1010 versions, and is a consequence of the the mechanical translation
from the pedal position to the underlying potentiometer: since a rotary
poti is used, the actual value plot ought to follow a sinus curve, but I
haven't tested this systematically.

I'm interested! In fact, I've written such an abstraction as well,
which I'm also happy to share.
