If you get into any communication with Korg and Yamaha, I hope you will bring up the continuing lack of standardization of MIDI codes for most common arranger functions.

Nearly 40 after MIDI first came out, and 30 or so years since arrangers became available, it is still unconscionable that the manufacturers have not yet got together and decided on common codes for such standardized functions as Variation selection, fills and breaks/fills, Intros and Endings, Part mutes, Bass inversion and transpose.

What should, in the 21 century, be a simple task of hooking two arrangers together and have them operate as one has been made needlessly complicated by a complete lack of standardization and often, the inability for front panel controls to send any codes at all..!

It’s laziness and inertia on their part. There’s absolutely no technical reason why two arrangers should not work seamlessly as one. Please, if you get their attention, bring this up…
