Also note that I've had intermittent problems using the iMate on the USB port on the G4 keyboard - sometimes it works just fine, and sometimes it doesn't and had to trash the digi prefs. I recently switched the iMate to the Mac's own USB port (at Waves suggestion) and haven't had a problem since. Make sure you get the 1.8 drivers for iMate (downloadable from waves.com). ------------------ LW
