I think they should consider developing something in the MIDI realm like this. Look at EZKeys as the general concept.
For me, the value as "WAV" files would be dramatically less, and this is the impression I get of what Craig developed.
A MIDI based tool means you can create it to sound like virtually any instrument and also easily manipulate variations. (Yes, I own Melodyne 4 studio)
It would seem such a tool could be far less cluttered than all of those Wav files to pick from. The "Wheel" in EZKeys being a good concept of general simplicity that offers any chord in basically a couple clicks.
