All other inversions are interpreted as m7. * m6 chords are only recognized in root position. All other inversions are interpreted as m7b5. * 1+2+5 chords are only recognized in root position. All other inversions are interpreted as sus4. * With augmented chords the lowest note played is assumed to be the root. * With 7b5 chords the lowest note played is assumed to be the root or b7. q FULL In this mode chords played anywhere on the keyboard are detected and used for Auto Accompaniment. Otherwise the keyboard functions normally, and the entire range is available for playing. Chord recognition is the same as in the NORMAL mode. This means you can play in just about any style anywhere on the keyboard, and the PSR-320/420 will automatically produce appropriate accompaniment. • A single note eleven notes higher than the lowest note of the chord is recognized as a melody note. • The Harmony function (page 31) has no effect in the FULL mode. 23
