FM-X Fixed Frequency (as opposed to Ratio) has a Pitch/Key ratio setting, far right bottom.
What is this rate's rate?
Is it possible to map a Fixed Frequency with this, across the keyboard, as per the keyboard's increase per key, or is it purely mathematical and unrelated to semi-tones and tones?

Translating... does that mean that setting Pitch/Key to 99 means that whatever the Fixed Frequency is set to, it maps 1:1 as tones and semitones up the keybed?

Seems that way. 99 was the old 127 and some (most) parameters adhere to the old DX7 99=max value. Some probably useless background stuff: volume doesn't map to the old 0-99 values so those need some translation between DX7 & FM-X.
Back to pitch/key: If you need less than 1:1 I imagine it's linear although hard to tell without verification. You could set to 11 and see if 9 keys up gives you a semi-tone (to check for linear response or not). And 18 keys a whole step and so on (when set @ 11).
Pitch is, for me, the easiest to resolve. And you can split your keyboard so you have maybe the bottom half of the keyboard set to fixed with Pitch/Key and the top half of the keyboard as pitched just as a reference (two different parts - different note ranges - true split).
