Well said Fran. You have nailed it on all counts.

And there is no reason arranger functionality couldn't be added to all workstation keyboards. It requires no special technology at all, it is only the onboard software. And workstations have plenty of buttons onboard that could be used for arranger control. It is simply economics that manufacturers keep arrangers and workstations separate to create 2 distinct markets. Though I am sure if Yamaha added Tyros functionailty to the Motif for every Tyros sale they lost they would gain another Motif sale. Plus it would add a lot of market appeal to the Motif as well. I guess the only difference is simply the labelling of the buttons. But that could even be overcome with multifunction labelling or clear overlays. Just a thought anyway.

Hey that is not to say that upgrading can be a good thing. Of course better technology is always a plus. But it really isn't always that important to your performance. While it is beneficial to you as a performer your audience often will never notice the difference because they are more focused on the performer than the hardware.
