RE: [xl7] Another XL-7 hanging itself

2002-02-20 by erik_magrini@Baxter.com

Yeah, I do all the things you mention already, although many times it's 
not even an issue.  I don't get stuck notes happening in same location 
each time (always random locations), so it's not a MIDI buffer overflow 
issue or anythign like that.  Plus, it can happen with only one track 
playing too, so...

Plus this is all controlled from Cubase, not the XL-7 sequencing.  After 
importing my pattern via E-Laoder, I set it up so that each XL-7 track is 
on it's own Cubase track, and basically leave it all at that with all the 
set up info still in the MIDI parts.  Then I start copying the measures to 
make my basic arrangement, until I get something workable.  At this point 
I erase all CC, AT, Vol, Pan and Sysex (everything but note data really) 
from the song, EXCEPT from the original measures at the beginning of the 
song.  That way I can play the track from the very beginning the first 
time to load the proper set up info, then I set my song start locator to 
where the "real" song begins, at say measure 17.  From that point on I 
don't have to worry about the XL-7 choking on too much midi data every 
time the original files loop.  All in all it works really well, except for 
the occasional lockup.

Sometimes lock ups are good (shoot me, I know) as they let me stretch my 
legs while it reboots, grab a beer, pack another, whatever.  Ok, they 
suck, just trying to find a positive side to the situation. :)

You can allready tell they don't expect you to use any other sequencer, 
two midi outs but only one in.  No fine tempo settings. 
You may want to slightly shift the offset time on tracks where notes are 
happening at the same time, if there is too much data you run the risk of 
overflowing the XL7's midi buffer.  This will make you lose note off 
events, timing events etc.  Also be aware that the XL7 retransmits to 
itself every time you hit start (Program changes, song position, setup 
information, whatever) so if you start/restart it cuts off the previous 
command before it has time to complete, basically corrupting midi messages 
if you do too much.  Give yourself a gap at the beginning of a song 
(preferably at a nice slow tempo like 60bpm with a tempo change at the 
begining of the actual song) to let the XL7 transmit all of it's settings.
