Thinking of going from SX900 to Korg PA5X

[Oldden]

Have a look on Facebook . There are a couple of Korg groups on there, I know some are private so you have to join before seeing if they are any good or not.

There are some useful resources here.

I have been using the SX900 for 4 years nearly every day, and have no problems with rattling keys or buttons. I did have Yamaha supplied grease applied to the underlying keybed  (Year One under warranty ) Other than that, I'm good, until possibly the next MOTL Yamaha (or Korg) Arranger.
