I downloaded OMB last evening and tried it with my Tyros. I must be a complete idiot, because I couldn't get the OMB arranger function to work. I was able to see the MIDI messages from the Tyros appear on the OMB screen, albeit, it was displaying a Bmin for a C chord? I was able to go into the Style maker section and get the styles playing normally.

On the whole, I don't really like the OMB interface. It's just too busy with useless information. If your playing live with this thing and you look up to your Laptop computer screen with this program displayed, how are you supposed to pick out critical information quickly?

I'll keep plugging away with it, but my first impressions are not very high.
