1) Is it worth upgrading to 'Band in a Box 2005' from 'Band in a Box 2004'?

2) Is it possible to easily convert 'Band in a Box' styles into Yamaha format (.sty) arranger keyboard styles? Is an additional special program required to accomplish this?

3) Has anybody here actually done this? If so, how do the results sound?

4) Instructions for converting Band in a Box styles to Yamaha (.sty) styles would be greatly appreciated.

Thanks,

Scott
