Do I suspect a little "well I use Yamaha so therefore it MUST be a better system" theme in your post Scott????

- but maybe not, so I will let it pass...Dennis
Hi Dennis
No, I didn't intend that one is better than the other, just that the same basic idea can be accomplished on both. I could have worded that a little better I think. I'm actually considering adding a Korg to my T4.haha
It's good to hear your comparison between the Tyros and Korg. For me, rather than play by a set list, I like to have songs in categories so if I think of a song I can go directly to that genre foler. Or, if I want to play a Latin I go to that folder and pick the one that strikes me at the moment. I'm pretty much an on the fly kind of player.
Anyway, this is great info to get out there because I think most players didn't realize it existed. That was also my intention of letting Yamaha people know they could do something along the lines you're talking about.
I have emailed Michael Bedesem, the creator of Open Text to see if he thinks the Unreal Book app would work on a Yamaha.
