A while back I was at a music store near here. They had a Yamaha Clavinova of some sort...around $12,000 or something like that. The piano had arranger functions...but, near as I could tell, not even as sophisticated as my $800 DGX 650.

I can't imagine Yamaha making big changes in the TOTL arranger; if they would make any changes at all. Yamaha is not known for bang for the buck...???
