Dear Arbaz,

YES, all Yamaha PSR's, even my quite old PSR-500, have the capability of "doing different things" (like introducing different phrases, or introducing different instruments) when chord variations (M,m,7th, etc.) are played. Very few internal Yamaha styles use this feature. I've mostly found it in converted styles from other synth manufacurers. When these styles (Roland, Technics, etc.) are converted so they can be played in a PSR you can here these introduced variations clearly. However, the effect is not very pleasing. You would not like it. Most of us try to MINIMIZE (e.g., get rid of) these features in the converted style (e.g., ELIMINATE the introduced new instruments, etc.) to make it sound better on our Yamaha PSR's.
