Addtiional details in via Benedetto Schiavone:

"As is known, the two Roland grooveboxes do not officially support MIDI SysEX messages and there is no documentation relating to their implementation which is hidden
In reality, the MC-101/707 are able to receive and send such messages: they respond with a completely wrong addressing, with duplicate and incorrect data which however can be corrected and used by the software.
The editor-librarian, like the analogous versions for Fantom/0, AX-Edge and Jupiter-X/Xm, communicates in real-time and bidirectionally with the groovebox, using MIDI SysEx messages."
