Completely delete your current AMS MIDI devices configuration (not by using the "Remove Device" option but by deleting the actual configuration). Select "Edit Configurations..." from the dropdown menu then select your current config and click Delete. Create a new one. Select "New Configuration..." from the dropdown menu, name it and save. Your 001 should show up. If it doesn't, Rescan MIDI. If it still doesn't show it's likely that either permissions are messed up or a file has been moved. Try repairing permissions. Doing what Darin recommended should work too-- but it's a bit more work-- do the above first. If none of that works, I'd reinstall PT. --- c
