It is easy to figure out the minimum span needed to play all chords in all inversions. If you start on the lowest note, C1, the major would end on G, the sixth on A, then seventh on Bb, and the major seventh on B. So, to play all the variants of the C chord family on the root C, the most distant note you would need to reach is B. Notes for chords above the 7th, can be played within that first octave. For example, the PSR will recognize C-D-E-G as C9.
So, look at B1 now. If it is to be the "root", then the furthest inversion would strech out to Bb2 -- a B major seventh. If you set your left hand split to strech from C1 to Bb2, you could play all the inversions of all the chords.
If you only used major and minor chords, by this reasoning, a B major with the B1 as root would extend only up to F#2. So, with the default split point Yamaha sets, F#2, you could play all the inversions of all the chords -- if you only used simple major and minor chords.
I generally have my split point set at G#2. I can't play ALL inversions of ALL chords with that split point, but I can play ALL inversions of most chords and still have some notes below middle C for the songs that require them. If the melody goes down to G2, I have to either change the split point, or simply change the octave for the right hand and play up an octave.
