Julie, and all:
As I recall, from months ago, Ted (I think it was Ted) said something
about the note-on event of the subsequent note being sorted so it
inadvertently came before the note-off event of the prior note, which
would produce a zero-length note.
My recollection of this is uncertain.

Hello Aera,
Sounds like when we save or load a .rg file we may be mangling things.
I remember -- many moons ago -- that I had to put in a Engineering
Compromise (otherwise known as HACK) for notes of zero duration of
file load.
Maybe something in that logic is messing things up. I'm not in a
position currently to dig around that code, but maybe for someone that
is, this could be a helpfuls starting point.
Sincerely,
Julie S

This conclusion puzzles me, because I don't think it fits the
symptoms.
Remember that I said that the first time I played it back, it
sounded fine?
One can't be 100% sure of their recollection of an event, but this is
how I remember it.
I started recording, and was pleased to hear the different
instruments
(chords vs. melody), thinking "Ah - it's working."
After stopping the recording, I was pleased that it didn't crash on
hitting the "Stop" button (which it used to do before you fixed that
problem months ago).
Then I played-back the entire recording, and it was perfect - no
missing
chord notes (like it used to do months earlier).
So I saved the file for reference, feeling good that the problem was
fixed. My memory of events here is not clear - I may have
re-loaded the
".rg" file.
For some reason, after saving it, I decided to play it back again,
upon-which I noticed many missing chord notes, to which my
thoughts were
"What the (expletive deleted)?"
The next day I examined the results in more detail, seeing the
missing
notes in the matrix (and notation) editors. That puzzled me.
I exported the file as a MIDI file (.mid), so my onboard sequencer
could
play it. On playing it with my onboard sequencer, I noticed the
missing
chords were there, but they were not continuous notes - if they were
tied, the ties were lost.
I remember there was a prior problem you (or someone) fixed with
exporting MIDI files, where somehow the note-off event was getting
exported immediately after the note-on event of the following note. I
conclude that the fix for this earlier problem was causing it to
export
the MIDI file without the missing notes.
But the significant thing in this long-winded e-mail, is that
given the
sequence of events I observed, It appears the chord notes were
messed up
in the process of saving the ".rg" file - not in recording it.
