I recently added a Korg PA50 to my PSR3000. I intend to midi them together giving me a good mixture of Yamaha & Korg Voices & Styles, but first thought I would spent time getting to know the PA50.
Well the PA50 is remarkable value at half the price of 3K.
Interestingly the keybed is better quality than the 3K. The complete internals can be overwritten so there is no need to keep those styles you never use, surely this is how all keyboards should be ?.
There is an assignable slider and assignable 4 PADS to do various things on the fly. Overall this board has turned out to be better than expected considering it's full retail is £699 uk pounds. Great value for little outlay.
