I used to own the Pa1x many eons ago and sold it solely due to the weight of the board. Lugigjg it around was a pain. Now after the s970 I bought the pa1000. First thing is the overall sound is more Live sounding. I still prefer the Yamaha styles a tad better and now I finally got the pianos on the pa1000 where I need them. I haven't been playing much but plan to do so soon. There is a definite learning curve over the Yamaha but I simply like the feeling of having more capabilities and sound customisation options and overall I feel I'm playing a more advanced instrument. Love the vocal harmony and mic sound. Spend the first 3 days singing off the songbook and the wife was really appreciative. Will post more updates as and when.
