The Yamaha PSR keyboards (including the Tyros) are designed so that the 4 style variation buttons can be configured (via auto fill button on/off activation) to either:

1) Immediately play the newly selected style variation (no fill preceding it)

or

2) Automatically play a 'fill in' before changing to the newly selected style variation.

I really like Yamaha's method because it makes triggering variations changes 'on the fly' (and automatically triggering fill-ins) a simple one button (intuitive) operation. On my KN5000, triggering fills-ins to precede style variation changes was rather cumbersome if I wanted to move from a style variation button which was not adjacent to one another: such as 1-3, 1-4, 2-4, etc. This required pressing TWO buttons at the SAME time

Is it possible, on either the Ketron XD9 or the 'new' Technics KN7000, to set things up so a 'fill-in' will play "automatically" preceding all style variation button changes, even changes like: variation 1 to 3 or variation 1 to 4?

Thanks in advance,

Scott
