this is what is going on.....

I have a pattern where i am using a large pad faded in as a build 
into the next pattern.  the pad has a long decay on it so it caries 
over the second pattern.

What is happening is kinda odd the notes are getting cut off in 
unpredictable ways over the second pattern.  I can't imagine that it 
is a lack of synth power.  It is a bisy pattern but come on a 128 
voices is more than enough for what i am doing.

Any one know what this could be?

it is making me go Hmmmmmm

I have never had that happen with the XX-7 but it does not sound like normal
behavior.  I have seen that "bug" before in other products where they don't
handle sustains correctly across pattern changes.  Not that it should matter
but is the preset assigned to the track in question changing across the
pattern?

I also agree with you that it is not likely note-stealing.  128 is a lot.
But remember that you can have four layers and a total of three linked
presets = 12 total layers.

I have seen polyphony consumed in a slightly different situation where there
is a pad sound, with long release, sustained for almost the entire duration
of a pattern.  Each loop of the pattern would retrigger the pad and use a
new voice.  if the release was really long relative to the pattern length it
did not take too many loops to eat a lot of polyphony, especially if the
notes played are a complex chord.

Another thing to check is that none of your tracks have an unplanned sustain
pedal commands (CC-64),  I am not sure what the Emu voice allocation scheme
does if a sound with no sustain is held with the sustain pedal.  if they
don't release it it will most certainly eat voices and you'll not know of
the problem because the sound will have already decay'ed.

Yup, I've noticed that sustain sections get stolen very easily, enough
to make them useless in practice. I played with the voice allocation
parameters - no obvious effect.

Adding Preset level Chorusing eats up polyphony too.

Good point, forgot about that one.  So lets see you can press a single note
and end up using worse case... 24 voices!

Suddenly 128 doesn't look that big!
