I suppose you are right Diki...of course playing the original instrument's keys and controls would influence how we play.
I still wouldn't go through the fuss and bother to have and maintain old gear...it simply isn't worth it to me. I like having the one keyboard and the one type action, and the Tyros4's sound set and semi-weighted FSX are ideal for my needs. I was even thinking of getting a weighted action synth and controller (Casio PX-5S), but, I've changed my mind, at least for now. The long term project I'm embarking on, only requires having the T4. Mine has the added memory upgrade, which has proved very handy.
We are all different in what we want (and need)...that's what makes life (and SZ) interesting.
The old gear will always have a special place in my memory, just like many other things back then, but realistically, an arranger keyboard, especially one as powerful as the Tyros4, makes far more sense (and is far more useful) to my present way of making music.
The monthly romp on the B-3 and Rhodes at the jam session is plenty enough to satisfy my jones for vintage gear. In fact, there is even an old mid-70's Mellotron (now in restoration) that will eventually be added to the jam gear, and as you know, it requires a special approach to playing...now, that'll be a hoot!

PS...Do you still have your two G-70's or has one been made redundant due to getting the BK-9? Are you using a separate amp/speaker, or going through the PA?
