Hello Anupam,
Not quite. I am speaking about the way a keyboard tracks the chord played with your left hand to generate the auto-accompaniment.
On higher-end keyboards such as the Genos, Tyros or PSR S, you can choose a chord detection mode where the keyboard recognises in which inversion you are playing a chord. If you select this mode, the keyboard will then be able to make a difference between a C chord spelled C E G, a C/E chord spelled E G C and a C/G chord spelled G C E.
Lower-end keyboards can’t make a difference between these chords and will always play them C E G, thus with C on the bass, even when you play them in various inversions.
On some keyboards, there was a way to “cheat” to play these chords in the correct inversion: if you played the chord with a note repeated at the octave, this repeated note would then be used as the bass note of the chord.
For instance, if you wanted to have a C/G chord, you could play your chord spelled G C E G, thus with the G repeated at the octave, and the keyboard would correctly use G as the bass note instead of the root note C. This was very handy to play songs such as a Whiter Shade of Pale by Procol Harum, where the chords in the introduction have other notes than the root note as the bass note.
Unfortunately the PSR E463 doesn’t have this “cheat mode” to play inverted chords. My DGX650 can do that, and I thought that the PSR E433 could do it as well, but I am probably mistaken...
