But... But..... But... If you want to loop stuff, why not make a pattern on the Genos/Tyros/PSR-S and instead of one chord just make a 4 bar chord progression?.. The PSR-SX900 is surely going to be fantastic, but i just don't see anything that sets it apart.
I’m not sure how to do what your talking about ( making a pattern) Maybe you could make a tutorial on your YouTube channel?
