When playing my micro electronic set I have a master pitch dial which allowed me to vary my drum set sound from bop to Bonham. I had a different setting for each song and thought it very useful.
I don't know about this though. I want my snare drum tuned so that it sounds great and meshes with the rest of the drum set. It's very clever, and there is no doubt a few drummers for which it is just the thing. I personally have no use or interest in it.
