Matty.You inspired me to spend an evening with my Yamaha 710. I still realize what a great little KB it is but I emphasise the little.
I know it's not in the tyros range but the amount of styles and performances from others on the psr site is wonderful.
However, I don't have a KB to listen to others play. I want to do my own thing and I feel that the pa3x allows for this.
I got very frustrated at the start trying to understand the manual but as I progressed, I realised that this learning curve was necessary to fully comprehend the instrument.
I guess what I'm saying is that no matter what KB it is, you will have to learn the operating system. Owners of tyros find them hard to manage too!
