Graham,

The Master EQ in OS 1.5 which should be available by the end of June should allow you to adjust the sound to your liking. It is very possible that the Pa800 you tried at the festival had OS 1.5 installed since Korg have demonstrated the new OS since Musikmesse in March. This might be the reason that your Pa800 sounds different than the one at the festival.

I don't quite understand why we have have to wait until OS 1.5 to get the Master EQ. In my opinion it should be standard on every pro keyboard these days.

Kind regards,
Tommy
