I just d/l\'ed the exs instruments for the sam horns library, and methodically performed the install steps.
To test, I brought up the mod wheel program for sustains. I am running on a dual 2ghz G5 with 2 GB of memory.
I noticed that as I played back a track where I recorded the MW off the triton, I could audibly hear the \'zipping\' of the MW action. Only after I went back into the hyperdraw viewer and replaced my simple crescendo with a \"straight line\", did the problem disappear.
It was the only track in the song, and audio is going through a motu 828 mkii.
