Problem with MIDI export/import of lyrics

I'm trying to export a vocal part (a score with lyrics) from MuseScore 4.5.1 as a MIDI file to import into a vocal synthesizer (Dreamtonics' Synthesizer V Pro ver. 2). SynthV is interpreting the name of the part ("Baritone") as the first word of the lyrics, so the actual words are all displaced by one note. What I can't tell is whether the problem is in the MIDI file that MuseScore produces or in the way SynthV parses the MIDI file. FWIW I exported as MusicXML, and the only place "Baritone" appears is in the part-list section, though how (if at all) this relates to the MIDI file I don't know...

Is there a tool (for MacOS, preferably open-source, or on-line) to translate MIDI into readable text (i.e. commands and their data) that can be used to inspect the MIDI file? Or could someone out there take a look at my MIDI file and see if there's something funny with it?
