At Bela D Media's websit there's a demo video for the Spiritual Wind and what got my attention (apart from that the sounds are incredible) was that the keyswitching and performance was done on a very small controller, maybe 49 keys only (or less).

This is something I can't do on my MIDI controller - I would have to use the transpose button in order to reach down to the keys where the switching is done.

Do I need a particular controller or is this something I can customize for any MIDI controller (I'm using Sonar PE 6.2.1 if that helps)?
