David Bowie always managed to use the Stylophone creatively....... Music comes from the musician, not the instrument (thank God!)
Somehow, Roland have lost their way, only using overproduced SMFs to demonstrate their arrangers, rather than what proved to be a very successful strategy in the past, and hiring very talented players to show what you can do in arranger mode.
As this thread demonstrates, you can get a lot of people impressed by a finely played demonstration of even 10yr old technology, even in the face of much more modern keyboards. The difference isn't in the keyboard, it's in the player!
Imagine what a good G70/E80 demo, done the same way as the G1000 demo, would do to the opinions of Roland's current line, which suffers from only being heard played in arranger mode by ourselves rather than a truly great player!
I had (still have, actually) a G1000 for 7 or 8 years, and I can positively say that the G70 is light years ahead of it, soundwise, but you would never know it from Roland's demos. They are overproduced to the point of disbelief, and desperately need a good realtime demonstrator to convince the doubters..........
