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.
Good luck to you and your music....
keep at it in time all good things will come.
