Could not find a specific answer if SysEx type data can be transferred/loaded for third party Synthesizer Keyboards via SysExLibrarian application using FireStudio Mobile Audio Interface as the MIDI conduit. I know I have used Midi keyboards to transfer MIDI data to my Mac through the FireStudio Mobile interface (which uses Firewire), but wasn't certain if there would be an issue transferring SysEx block information (send/receive) with the FireStudio Mobile Audio Interface through MIDI IN/OUT connections. Thanks.
