Thanks everyone. It is encouraging that you liked it and I feel better about using it so much on the job.
My body isn't what it used to be. My fingers get stiff on heavier action keys. I have neuropathy in my legs and not really that steady carrying the heavier keyboards. Even though the PA4x is really no problem, this thing is REALLY light. And, I'm losing some high end hearing, just a little so far, so welcome observations on the balance and e.q.
On top of fall that it is a joy to play so far. If it gets boring, I'll switch back for a while.
