Perhaps you could use the freeze button to freeze the tempo?
The freeze button does not work. When resetting live control values, it resets the tempo also. Freeze is only for registrations.
I would just select again the style you are playing.
Very good idea but I have to select quickly another style and back to the current style to reset the live control values. Not very easy when playing.
Another way is to store the current style in a registration. The problem is that the registration recall the style variation stored.
I don't find a simple way to reset the style parts to the default value without changing the tempo.
