I use the Pa4X, Audya 76, and S970 on a regular basis, and will soon add a Ketron SD40 to my Hammond SK1. I only gig about three times a week, but music is a full time adventure for me. I could easily gig with any one of them and the audience would be happy, but I selfishly play what and when I want to. This means always looking for a better style and sound for each of the perhaps 1000 or more songs I do. This, to me, is pure enjoyment and a challenge. I have a core of 150 songs on each keyboard,then add a hundred or so to each playlist. they are all different, yet the same song. Additionally, I like to go through the styles in all of the boards to give me ideas for new songs, as I am always trying to be at least somewhat relevant in this everchanging world.
