You've lost me here. There are no patch changes. The glitch occurs
during playback when touching a region of memory for the first
time while rendering, for example a region of a wave table.
(I say "first time", but I presume it could happen whenever that
memory is paged out).
This seems like an inherent danger of using virtual memory in
a real-time system. What strategies are people using to avoid
page faults while rendering audio?

Your "host" should be calling prepare instrument before it expects a

MusicSequence / Player to actually fix this properly (which it now is:)
