The Artiprog (I think we're talking about this: https://artiphon.com/) is one amazing controller. Six stacked octaves [for a keyboardist] with velocity and aftertouch for $400? Dear God, what hath thou wrought :-) I do hope they do an eight-octave version, I would miss the extreme octaves, but still, wow.

Response to pitch bend is partially a function of the soundfont loaded into fluid. There are several (lots?) that don't respond, and many that do.

I very very much doubt that Fluid responds to the pitch bend range RPN, but hey, I've been wrong before.

It does appear that Fluidsynth knows about pitch bend:

https://github.com/FluidSynth/fluidsynth/issues/154

but given that you're not hearing it happen, there may indeed be different question-beasts involved, both soundfonts' responses and/or fluidsynth options. I have done a bit of editing and study of some soundfonts ( http://polyphone-soundfonts.com ) and did not see pitch bend response in the GUIs, though I will be unsurprised to be told better.

It appears that Yoshimi and ZynAddSubFX, live synthesizers, both do pitch bend:

https://sourceforge.net/p/yoshimi/feature-requests/13/

and live synth should (theoretically) be more of a slam-dunk for pitch bending, because pitch control is not an option for the live synth, it's an absolute base-core item...whereas soundfonts themselves contain discrete note-chunks that would have to be morphed by the soundfont handler to make it happen well.
