I always try to remain open minded about new equipment from any manufacturer and often try things I would never use on a gig and end up
selling whatever it is. The S950 will work just fine for my gigs.
That being said, when I changed from my Tyros 3 to my Tyros 4 I was not all that happy with my purchase for nearly 2 months until at almost all of my gigs people made comments about how great the "new" keyboard sounded. The thing is, I never told them it was a new keyboard but they apparently could hear a big difference. I know for sure I was booked at several venues in place of others because the people liked the sound of the T4.
Right now my physical situation demands I find a suitable lighter keyboard to gig with and that will not change for the rest of my life. We will see how it goes with the S950.
