I had this issue here as well. I think I trashed the AMS setup, trashed the .kext file for the MOTU and trashed the drive. Installed the latest driver. I think this was happeing on Mt Lion, Maverick, I dont think Ive had it with Yosemite or El Capitan

you can trash the apple mide setup in prefs as well. Youll have to re- do the AMS though
I think this was what was happening to me as well.

Maybe he's using a bus powered interface?? That might make it kick in later and cause the phantoms.
