Just been reminded of something which happened on my kn6000 which was never sorted out and same thing happens on my 7000. Using APC with technichord on block piano and play a left hand C9 chord (CDEG). The right hand produces a dischord. Try alternative fingering for the C9 i.e CEGD and same result. Try a G9 chord and another discordant sound. In all cases the screen displays the "9" chord being played,and the APC accompaniment is OK. I'm not expert enough to identify the dischord produced.
As I say this also happened with the 6000 so it would seem to be a generic Technics fault rather than a fault on the 7000.
Has anyone else experienced this?
Alright so I should play fully fingered right hand chords but I ain't no expert.
