Good topic, Donny.
I'm pretty comfortable with the Tyros4, and wasn't tempted in the slightest by the Tyros5...or anything else from the other brands.
My arranger has all I need for the present and whatever comes along...it provides a good base to work from.
I have learned to dig in and maximize what I use, which in the case of the arranger, means editing and putting together new styles, as to me, that's what will make a person's arranger, and music created on it, have it's own signature. I believe the styles are the soul of the arranger. Yes, sounds are as well, but I have all the basics, like a great piano, electric pianos, guitars, saxes, strings, organs etc. and the memory expansion that lets me add more.
I honestly can't see me buying anything else for quite some time.
So, yes, I'd be happy with what I have, and more importantly, I don't think it needs anything to make my experience any better.
Ian
