BTW - The HDSP interrupts above do not represent a failure. All I did is
what you asked me to do. If you asked me to wait for a failure, we'd
have 1000's on interrupts at least, I'm sure, and I don't know how we
would identify that one did not happen.

Also, if I wasn't clear earlier, the failure is ONE stuck note. The MIDI
input keeps working, and subsequent notes work properly. (both on and
off) It's just that a single note gets stuck every 1-2 minutes.
