Hi Dnj

Good question.

Yesterday I bought an old Yamie arranger PSR5700 that seems a brandnew kbd.
I installed the old grandfather in a double Ultimate stand and made the mid conection with my Psr 2000.
Just some tips:
The grandfather made 7 or 8 years ago, is easy to operate and play, when compared with PSR 2000 with some features that I loved.
Individual buttons for each control (No pages and sub pages,and sub pages,etc)
Slide controls for each volume.
Perfect keys touch (I think that is the same of DX7 synth)= OH new PSR: whata shame!!
I always love the eletronic development but some features as individual controls are important for live musicians, IMO.
Regards
Chico
