lower and higher octaves -4 / +4

[fredstep]

It would be great if we could go to -3 and -4, and +3 and +4.
Perhaps the led on the arrows could change color to indicate the lower octaves.

The current maximum of -2 and +2 is quite limiting.
Especially if I want to run it with key-switching vst's like kontakt.

This is a bit strange, as doesn't the smaller/cheaper versions of Arturia Controllers, do more than +/-2 octave?  Keylab, etc?

This should be expanded.
