I use the SA Buttons on the wind instruments about 1/3 of the time...the wheels are just that much easier to use to add very subtle pitch offsets. The beauty of the buttons is that you can usually preset a bend or trill by pressing the button a tad before you hit the note, so it does help a bit when a chord change would otherwise make it difficult to use the wheel.

The pedal steel on the Tyros4 is pretty realistic, but the bends do seem to want to be activated at chord changes. I also like to layer two guitar patches, with only one responding to the pitchbend wheel...that way I can bend one note up to be in unison with the other.

The SA/SA2 sounds themselves (winds, strings guitars etc.) are excellent nonetheless, so I don't mind the trade-off.

I went to quite a few seminars at Yamaha Head Office in Scarborough Ontario after I completed the Electone course, where we were instructed in the ranges of the orchestral instruments, and that has proved valuable for using the arranger.
