I had a Tyros 2 and a PSR-S910.... but used the Motif ES to sequence full arrangements from scratch.

Then I went through a few for a gigging option to playback files while giving me good sounds to play along.

Roland BK-9
Korg Pa900
Yamaha PSR-970
Korg Pa4X

By far, the Pa4X sounds the best (to me) all around. The Maxx Audio stuff... better outputs... keybed feel... overall construction of the “Made In Italy” instrument... and the sounds are great!!

I love the Pa4X but I will have something else in my near future!! I wish I could keep both... best of both worlds but I need to sell things to get things... room and budget are factors. Good luck with your choice!!
