Recently, I wrote about a MIDI piano losing notes.  In particular, I
wrote that

This "turns out not to be the case".  The data headed for the piano is
_not_ the same.  I got frustrated enough to plug the computer's MIDI
out into its own MIDI in and thereby spied on what it was sending.

The resets generated by seq_reset() on open (which I was not previously
aware of) appear to be responsible.  When I insert not only the delay I
refer to above but a copy of the seq_event_recs corresponding to those
resets, the piano behaves as in the "run the player twice" case.

This is discouraging; it means there probably is no fix, since the bug
is in the piano. :-(  Anyone have a bug-reporting contact at Korg?
