Why not? It’s a common equipment and it’s not count as "digital device forbidden in analog studio" as you connect synth directly to it, just to make sure that your front waves are in sync
But it's not about audio jitter.
Anyway, like I said, too much speculation in this thread.
Yes, MIDI jitter can be compounded on the receiving end - but having a very tightly bound MIDI clock to the audio clock can negate a lot of those issues upstream in the first place, and that is precisely why you get a good audio interface that does this anyway.
(Disclaimer: have worked in pro audio product development for decades, have written drivers for exactly this use-case, and I have personally been in the trenches to fight the myths about Audio and MIDI jitter as a developer for a long time now..)
