Hello S970 fans. When I set the style playback to 'Medium', the volume changes in a middle range according to the strength of the keystroke. I have understood the lack of more detailed explanations in the reference manual in such a way that the accompaniment can be heard relatively quietly with a slight touch of the accompaniment chord and loudly with a stronger touch. Now I have however ascertained that eg with low accompaniment by stronger striking the Right1 or 2 Voices likewise a volume increase in the accompaniment occurs. Actually a strange result. Does it have to be so?
