Just to add to what I'm saying for example...

The Ketron “Audya” has to be by far the worst name for a keyboard ever, although the Wersi “Abacus” comes a close second.

Using just numbers is safe but it kind of doesn't make things that special. Like the KORG Pa2X. It's a very suitable product identification name but it doesn't leave you with that special magic the name KORG Trinity, or KORG OASYS does. Now those are two very cool names.

Your buying a musical instrument at the end of the day and your going to pour your heart and soul of emptions into everything your going to play on it. So it deserves a special name not some generic number more suited to a Jet Fighter or a uncool part of the English language.

Cheers
