| In theory you will get some jitter added to your timing, since time is
transmitted over MIDI in analog rather than digital form.
However, in practice I don't think you will notice. I've never
done this myself, but I've seen a recommendation in a magazine
that you use this technique to get around the lack of
an "unmerge" feature in sequencers, so I expect it will work
satisfactorily.

711.2 | Operation a success, but patient dead.... | JAWS::COTE | Ex-Bank Officer and PROUD of it! | Wed Mar 04 1987 08:29 | 41 |
| Last night I attempted to perform this exercise with some predictable
flubs and unpredictable results.
I seguenced 2 parts. Part 1 consisted of 8 notes played on
MIDI channel 1, one measure long. This was then moved 2 track
2 on the QX. Part 2 consisted of 1 blank measure and 8 notes played
on MIDI channel 2, for a total of 2 measures. These 2 parts were
then combined. By switching between OMNI recieve, Ch. 1 recieve
and Ch. 2 recieve, I could play back both measures or either.
The MIDI thru port of the DX was then routed to the MIDI in port
of the sequencer forming an endless loop. QX out to DX in, DX thru
to QX in. I set the QX to Ch. 2 and attempted to record on track
1 while playing back on track 2. I started the record process. There
goes the 2 bar countdown and VIOLA! MIDI BUFFER FULL ON THE DX!!!
This was easy to fix. The QX has a MIDI echo feature which passes
all data appearing at the IN port to the OUT port. With this feature
enabled, the same data went round and round until the buffer pooped.
No sweat, disable MIDI echo and try again.
This time everything appeared to go fine. No buffer problems, no
clock problems. I stopped the sequencer at the end of the 2 bars.
Since I had set the sequencer to channel 2, my assumption was that
only Ch. 2 data would be recorded, leaving me with a fully merged
track 2 and 1 empty measure followed by Ch 2 data *only* on track
1...
Nope.
When setting the QX to MIDI Ch. n, *ALL* data recorded will be recorded
as that channel. F'rinstance; set the QX to Ch. 1 and load it with
data from *any* channel, 1 - 16. The QX changes it all to ch. 1!!!
What I ended up with was not a separation of the 2 channel's data,
but rather, a re-channelization of either or both. This effect
undoubtedly will have some use, but it just wasn't what I was hoping
for.

| As long as you're cleaning up editorial infelicities (now, ain't that
a nice euphemism), "viola" is the instrument, while "voila" is the
French expression.

Gahd, that was terrible wasn't it? I feel like such a twit! Here's
a spell-checked, edited, and proof-read rev. So sorry for the incon-
venience....

| "seguenced" still doesn't look right, unless you have a cold.
It sounds like the QX is always in "OMNI ON" mode; too bad.
You might be able to fix the problem with a fancy outboard MIDI
filter, but such a box would be expensive enough that you'd
probably be better off just getting a better sequencer. I think
you're stuck.

| The QX defaults to "receive all channels as sent" mode. I mistakenly
thought the "Select MIDI channel" command would allow it to only
listen to a selected channel. Instead, it remaps any data at the
IN port to the selected channel.
Dumb. Dumb. Dumb.
