Hello:
I know you may miss the dedicated sliders/drawbars....but in exchange, you gain more poliphony, more RX sounds, new sound engine in MOST areas, also you will NOT miss the dated Floppy disk, instead, you get access to a the fastest USB 2.0 .....with more capacity...also, more memory for the sampler if you use it.
I really like my PA800, had it since it came out, I have installed the latest OS. Works just Great!!!.
I did not own a PA1X, but, at the store where I used to work, I played a lot too, not as much as the PA800 or my T2.
