A good exercise when learning new chords is to play them, after you have learned them in root position, in the other inversions, too. So, for a C chord, play CEG first, then play EGC, then GCE. Without the On Bass feature on, they will all sound the same. But with it on, they will all sound subtly different.

This will not only help you when it comes to slash chords and inversions, but with on bass off, it helps stop you from jumping your LH around so much, as a G major to a C major can be played GBD, then GCE... Your hand doesn't move, and only two fingers do, too!

Mind you, I like Donny's approach, too. It doesn't matter how messed up you get the chords - it's not WRONG, it's just 'making it your own'!
