I agree completely, squeak...
It's the CONTENT, not the technology. An arranger loaded with as contemporary loops and sounds as say a MotifXS would, IMO, sell FAR better than the MoXS itself, simply because of the easier interface that arrangers have.
But because of the balkanization of keyboard lines, we get the better interface and the dated styles and sounds, and they get the cutting edge stuff but can't control it as easily... NO-ONE WINS!
Give me a MoXS with a T3 front end, I could make some hits on TODAY'S charts!
BTW, before you go overboard about the volatility of today's chart music, you have to understand the the music business is working on revenues that are close to 20% of what they were pre-Napster. There is no money for developing artists, and no way to promote artists the way that it USED to be done (and resulted in long-term hits and careers). And so, just like every other form of communication and commerce in the Internet Age, things move at a MUCH faster pace.
Food for thought...
