Up!
I got the same problem writing for bras section :
2 Bb Trumpets
1 trumpets a3
1C trumpet
2 Ternor tbrnes
1 Bass trbne
On logic pro 9.1 if i Playback only the 2 trumpets => OK
the 2 trumpets and the "a3" section => OK
All the trumpets (including "C"one)=>OK
All The brasses except Bass Trbne=>OK
All the brasses=> KO i got stucked note on the VI keyboard on my slave PC randomly on trbnes or trumpets.
To sum up it's going well if i choose to playbak 3 or 4 regions but not well if I playback all.
For information I set the buffer size to 1024 (got a PCI motu 24 i/o).
This is very wierd for midi regions really seems to interfers together (althought these are not on the same midi channel) for example i tried to playback only the two Bb Trumpets all the keyswitches react well (if i look to the patch section on the VI the articulations change at the right time and the keyboard has not a single key stucked)
but
if I playback all my regions the articulation on my Bb Trumpet seems to be messed and I have keys stucked (most of the time this is always the same key wich is stucked)
Do you think this has something to do with polyphony? Buffer? The buffer on my core audio is on max and indeed if i Go back to 512 it goes worst.
I don't know what to do,
Anyway thanks for taking time reading this awfull post.
Best regards
Nicolas
