Perhaps it is time to start REALLY pressuring the manufacturers to be complete in their MIDI codes to allow remote control of an arranger, and make the MIDI implementation flexible enough to route ANY Part to either Internal or External (or both!) Tones.

Then, you don't have to wait patiently (and wait, and wait, and...) for them to come out with the PERFECT arranger (which will only be perfect for YOU, anyway!). You merely combine two different arrangers into one Über-arranger that is prioritized for YOUR needs.

In fact, the return of the arranger module (that always WAS flexible in it's MIDI) would be even more welcome.

But without the codes... forget about it!

They managed to come together and standardize for MIDI in the early 80's. Let them know we need a standardized arranger control system. And make them realize this will increase their sales. Might almost double them! I would happily have two arrangers if the bloody things would just TALK to each other...
