The solution with Korg is a bad and sometimes inaccurate. Yamaha’s approach is more correct and we can act with complete precision. If we add the [High Key] parameter to this as the point where the instrument transitions to the lower octave, we have complete control. The - / + 12 concept makes sense for Right sounds, but in the Style area this rough division can only be used if the instrument is sampled in the wrong octave.
