The more I see and hear from Tyros2 convinces me this is an amazing keyboard !
Just visited the US Yamaha site with the short (solo) demo of Drawbar-, tonewheel-, rotaryOrgan-, or Hammond-sound including the Leslie effect....WOW !!
This comes VERY close to the original :
Depth, scanner-vibrato, warmth, percussion, Leslie speed up/down.

I sold my Tyros1 yesterday and now the real waiting starts .... I hope 4 weeks or less.
