Hi Roger, you are safe,( it's a bugger being perfect),I am most of the time.
John, I am always smiling when i play my KN7, good playing with yours.
On another note......many of the songs and styles I have collected over time have the split point at second position, (hi! Mr Norrie), which limits ME playing Rt.hand below middle C, in particular "piano".
I play all left hand chords between the two F's when rhythm is used with split keyboard, (old organ training).
Is there a particular reason for this split position???
