That's not a fix for the problem, though. That's a Band-Aid over a deep wound.

So the answer to those that prefer 76 is to carry TWO keyboards around? Please!

And it's already been well documented how many compromises you need to make to integrate that second keyboard. You can't lay it out how you want from within the T4 OS, you have to do quite a lot from the 76 itself, making registration changes a far more complicated procedure.

For people happy with 61's, then yes, this DOES look like the solution to the problem. But only because you don't HAVE the problem! If arrangers generally only came in 49 note models, and you had to jump through these kinds of hoops to add a 61, trust me, you would NOT be considering this 'problem fixed'!
