You may have noticed that the alternative tunings preloaded at the factory (and available for download
here) have cryptic names on the Rev2 display, apparently limited to 8 characters, which turns out to be totally unnecessary: The MTS sysex specification allows for 16-character names, and the Rev2 is capable of displaying them fully.
Here's an updated sysex, edited with names that are more human-readable. Comments or suggested improvements welcome.
PS: More to come on support for alternative tunings on the Rev2.
