Hi Anon,
if you are not a jazz music expert and don't mind if the bass in the style is playing not exactly the root note that you want, just play the chord as you read it in sheet music.
No matter if you play 1st,2nd or 3rd inversion of the triad basic chord or the 7th chord, the keyboard will play the first inversion.
So it is really useful to play most of the chords in just one octave's gap.
Personally I use inversions of chords between the F key to F# key (the key where the split point is). There are just some rare chords that have not an inversion between those notes.
With the AI fingering mode I can get some great help while my left hand is not so... co-operative to move around in all the keybed
