If you use a velocity switched fast/slow organ sound, you can restrict ALL the velocities to just UNDER the fast vel level, then select the section you want as fast, and just add +1 to the velocities. It works great, and you don't get a big jump in volume when you do it. I've edited a few Roland styles to do that, as you can't use the VK organ section in a style (

) and it works well...
I haven't had a great deal of time editing and assembling style with this new one, but, being able to use SA/SA2 voices in the style parts is definitely a
big advantage. There aren't any velocity switched fast/slow organ sounds on the Tyros4 that I know of...but, I will say, that I am going to have a lot of fun with this instrument regarding making (assembling) my own styles.
Velocity control rotary for RH voices isn't anything I'd want either.
