Hi, why are my external Midi synths not appearing correctly in the device list in the library panel. They are setup correctly in the Mac audio midi utility and have been saved.... But in various sessions they appear incorrectly in the left-hand column. Devices are missing the right number of midi channels or they respond under the incorrect name. If I start a brand-new session everything is correct but all the older sessions appear wrong. Even if I refresh the library it is incorrect ..... is there some kind of preference that has to be deleted or something?
