after using the EQ settings above...
thank you to robbinez on the Psr tutorial site.
I loaded all my S970 Registrations and User styles with out a problem via USB of which there are two on the back....
Fired up a few songs and they played perfectly only now with a more clearer, crisp sound. There is a slight learning curve to getting familiarized to a new touch display menu but nothing for someone with Yamaha arranger experience to figure out in 15 minutes,....things are just in different places but work pretty much the same as previous models. The black menu background kind of enhances the TINY Font white lettering ....if I'm being honest after 1 hour since unboxing and setup as described above I could easily take this SX900 on stage with no reservations right now as is! ....but now the fun part in the next days will be to DIG IN Deep and really set it up for MY needs utilizing all the nice features this unit has to offer.
