hi,
actually it would be interesting to know "who" buys arranger keyboards and what percentage is the hobbyist and what percentage is the professional musician.
I'm guessing, but I would imagine the bigger marketplace may well be the hobbyist. If so, with the advent of software arrangers, keyboard manufacturers may have something to worry about.
I've been a keyboard junkie for nearly 20 years.
I've had the
Technics Kn800,2000,3000,5000,7000.
Roland E20,E86,G800,VA7, RA90, Ra95.
Korg i2,i5
Yamaha PSR6700, 9000pro, DGX305
QY10,20,700 ( not true arrangers, but I thought I'd include them anyway)

In between the Kn5000 & Kn7000 I had a 2 year break. No doubt my list would have then also included the kn6000, kn6500 and the Roland g1000 as I normally update both kn & roland when each new model came out.

Won't bother listing synths, samplers etc

In the end I finally thought what for, I can now get my arranger functions thru a piece of software. There's no shortage of styles floating around and, the software can help me create my own . The one luxury I have is a beautiful Yamaha digital piano
(without arranger functions) that I use as a controller. My junkie needs are fulfilled.

Be interesting to see what the Tyros2 is like.
Can I afford it "yes"
Will I buy it "I doubt it", it's going to have to be pretty amazing to get me hooked again.

best wishes
Rikki
