Thanks, will do.

Makes sense to me.

Should be, I'm calling snd_seq_event_input() in a tight loop. Hoping
this is the appropriate function to be calling, and that all the various
structures around it are initialized correctly.

It already does, in a way. Anything that has read/write permission,
direct and/or subscription, is usable. I like showing everything, it's
useful for diagnostics/troubleshooting. If user wants filtered output
they can apply that later (or perhaps I'll add it when adding the
--quiet flag). I still think the most complete/useful output should be
the default.
