Scott, There is another thought here. I see three main areas;
1-Playing the keyboard.
2-learning to use the soft ware(midi files, storing, ect).
3-Learning every part of the keyboard that adds to your performance and enjoyment.

For me--IMHO---I have met with so many players that use 20% of the fantastic features in the keyboard. The keyboard was designed by a group of real professional people, they spend their days and weeks creating features that will help us perform. I try to explore and experiment with every part.

When I hear a song being played on TV, radio, or wherever, I get back to the keyboard and ask myself, "How can this keyboard create what I just listened to".

I work each section of the keyboard until I am comfortable. Then I am off to the next area. After years of searching, I am still finding new ways to use the keyboard. It is me that is growing, and I feel good about that.
The good part is that I take that knowledge and ability to the next generation of keyboard, the next model.

For those who have different needs and desires, that's just fine. How boring this world if we all followed the same drummer.

Thanks for leting me share, John C.
