Audio is breaking up and cpu performance is overloading when triggering MIDI instruments such as Superior Drummer or Sampletank 2.5XL etc.
Audio recording is fine.
Triggering without the Ultralite is fine (using the computer keyboard), so I think it must be OS X's MIDI drivers or the Ultralite's.
Reloaded the Ultralite driver- v 1.4.9./ Ultralite firmware v1.1.5.
Never had a problem before.

Thanks.

OS X 10.5.5.
Powerbook G4 1.5GHZ
2GB RAM
7200rpm external

I am going to take a wild guess and say that it is probably your ultralight midi drivers. I used an M audio Oxygen 8 to trigger all kinds of midi with Reaktor 5, and Moog Modular 4 and Absynth 3 on a G4 and never had any problems. However, it just depended on how many tracks I had open as well....I often had to freeze midi tracks or other tracks with plugs to not get overloads. With my G4 I could only handle 18 to 24 tracks maximum before I would get stuttering and dropout...and this was with all the necessary tracks being frozen.
