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.
