FWIW, I thought yours was a darn clever solution.
If you write to a file in specialFolderPath("temporary") you'll get the
file without risk of permission errors, while avoiding ever having the
file seen by the user.

Latency. For things like whole MIDI files (which will require a fairly
substantial subsystem anyway, whether it's QT or something else) it's
probably not so bad, but the desire to see multi-channel sound using
Rev's built-in soundClips is motivated by circumstances where minimal
latency is appreciated.
This post from Judy helped me appreciate such cases:

While such cases are somewhat rare as she notes there, if you need the
fastest possible responsiveness its hard to beat soundClips, since
they're already attached to the stack in memory.
The more I think about it, however, the more I find myself wondering how
satisfying it would be if it were available.
If you're writing for a machine old enough that such things matter you
need to be very prudent with RAM, so the number of soundClips needs to
be kept to a minimum.
Given that, and that older machines have so little RAM, I guess the
central question is, "What sorts of sounds would one want to play?"
While referring to HC's notation as "door bell jingles" may sound
derisive, these days when people are accustomed to richer sound design,
it's not an entirely unfair characterization to the modern ear.
For music that leaves us with MIDI as arguably the best balance between
file size and audio quality. But while MIDI files are small, the
subsystems needed to play them are not, leaving us back to pondering the
balance of responsiveness and quality.
So if not for music, then what is the anticipated usage for such an
external?
