Brickbo,
Likewise, one of the most important reason to getting an arranger is to be able to utilize its styles and to "arrange" its styles into a song. If an arranger is not capable of doing this or makes this process difficult, then maybe it should be called somthing else. I have done some research on this matter and the keyboards capable of doing this are the Technics kn series, the Korg i30 (thanks to you), Yamaha psr 1000/2000, and now the Tyros. All others are useless when it comes to this subject. I also have the pa80, Solton X1, Psr9000....all very limited in its ability to navigate thru the song and make changes as you like it to be.
