Hopefully Robert will work with Paul and the programmers to incorporate all of the changes and additions that have been made since 1996 including, but not limited to:
Scale/Octave Tuning Scale/Octave Tuning Defaults MIDI Tuning Bank/Dump Extensions Redefinition of RPN01 and RPN02 (Channel Fine/Course Tuning)

John gives a lot of different "standard" tunings here. I or someone else should try and convert these into MIDI files so that the PC and Mac frontends can download them easily to the '650. There are a lot of glaring omissions in this list such as pelog (7-, 6-, 5-, 4- and 3-tone) and slendro (4- and 5-tone) tunings (all of these represent different aspects of Balinese and Javanese style gamelan).
