How to account for offset mod wheel in pitch mapping formula

[a52]

A midi controller I have has a spring-loaded pitch wheel that rests at 54% instead of 50%. I've come up with some simple linear equations to fix this for most parameters, so that 54% maps to 50%. But I can't seem to figure out how the pitch mapping works. If I set the mapping formula to Input + 0.01, the channel pitch bend wheel is offset by a good 40% or so, not 1%. Also, if I turn my (physical) wheel to 100% it offsets the pitch by 2 semitones, putting the (digital) wheel at max. But if I set the pitch mapping formula to just be always 1, it turns the (digital) wheel way past 100% and the pitch is shifted by several octaves.

How big is the range for the pitch wheel? And is there some kind of scaling of the input going on beforehand?

Automating Channel Pitch always results in -+48...

Thanks, that would be much easier.

Try re-calibrating the pitch wheel on the keybo...
