Bigger Virtual Keyboard?

[Pyre]

Hi all, I'm running VI with three different MIDI controller keyboards - 25 key, 61 key and 76 key. This gives me a great number of octaves to play with, far more than the seven octaves of the virtual keyboard at the bottom of the VI interface. Is there any way to add extra octaves to this, above or below? Even my little 25 key M-Audio controller can hit notes an octave outside of the virtual keyboard range at both top and bottom, thanks to its transposing abilities. I am hoping I can have a full two octaves dedicated to keyswitches, and so would like to keep these away from the big instrument ranges of things like harps, which it might impose upon with just the standard 88 keys. Many thanks.
