Another peculiar question

Another peculiar question

2003-04-21 by drewaight1

Here's a very odd Bug ive been having. 
One of my patterns has a distorted guitar chord in it. I turned the 
sustain and release knobs far to the right so that when I hit the key 
it slowly fades away, (just like a rock guitar big strum). Sounds 
great. However, after my pattern has been playing for sometime the 
sustain and release on that preset randomly revert to being short, 
ending the guitar hit where I let go of the key. It seems to be at 
random, and it also seems to be worse when other tracks are playing, 
I have tried erasing all controller messages and resaving the preset 
with the sustain and release turned up but to no avail. If anyone has 
encountered this problem, or more importantly the solution it would 
be greatly appreciated. Thanks.

Hi, this is actually a basic problem with all synthesizers not just EMU's.  When
you turn your decay all the way up the note is still on until the entire note
and decay are done playing.  So when you are playing multiple notes each of them
takes up polyphony.  You only have 128 voices (or samples) you can play at once
total, and the guitar patch may actually use 1 to 4 samples, so if you have 16
notes of guitar per bar, and you have several seconds of decay per note, by the
end of the bar you might be using anywhere from 16 to 64 notes of polyphony,
after two bars depending on your tempo this could equal 128 voices.  If anything
else tried to play, there wouldn't be any room left to play.  Synthesizers use
"note stealing" to cut out the oldest notes first to make room for the new
sounds.  So the more tracks you have the more noticable this will be.
A guitar isn't usually played like this anyway, only a few notes are actually
left open at a time, they restart the decay when you strum, and the other notes
are being changed, so realistically you have many different decay times going on
at a time. You could make a copy of the patches and save them with different
decay times, and only use a few of the full decay ones at a time mixed with the
"strum" or note pick decays.

Hope this helps,
Andre

Sound like you're just running out of voices so the chord gets cut off. Is 
this a fairly busy Pattern?

I get the same thing, though I never noticed it being a knob issue, which 
is definitely a possiblity.  Occasionally (70% of the time) when I power 
on the XL-7, the Preset on Channel 1A will show that it's dirtied.  Makes 
sense with what you say, since the Knobs default to Quick Edit mode on 
that channel upon power up.  No idea what's causing it, but I don't think 
it has anything to do with his issue (I could be wrong though).

Are you sure it's your Pattern getting dirtied, and not the Preset?

     Sometimes (especially when I first power up the XL-7), one of the 16 
knobs will suddenly send
its current value, essentially "dirtying" the pattern.  I can see this by 
the knob LED that lights
up.  Sometimes just changing to another pattern and back is how I fix 
this.  Other times, I just
switch from "Quick Edit" to "Volume" via the upper left hand button.  This 
is a hardware bug it
seems to me and may just be affecting my machine.  Perhaps this is what's 
happening to your
machine too?

     Sorry, yes it is the Preset that gets dirtied, that's why I thought it might be the problem
that was posted earlier.  If the guitar patch is on channel 1 (or the active channel on the
screen) and the beast is in Quick Edit, this might point to the problem that I mentioned.

     It seems to happen to me within minutes of powering up the beast, and only on the active
channel (by default, channel 1).  Perhaps something about the machine warming up?  It never
happens more often than that.

Mine just powers up with the Preset dirtied if it happens, it doesn't 
happen after a few minutes or anything.  Weird, oh well, easy enough to 
work around :)
