• The auto accompaniment will sometimes not change when related chords
are played in sequence (e.g., some minor chords followed by the minor seventh).

The sound of the voice changes from note to note. This is normal. The AWM tone generation method uses multiple recordings
(samples) of an instrument across the range of the keyboard; thus, the actual
sound of the voice may be slightly different from note to note.
The harmony doesn’t sound. The method of sounding the harmony effect (01–26) differs depending on the
selected type. For Types 01–05, turn the Auto Accompaniment on and play it
by pressing a chord in the auto accompaniment section of the keyboard, then
play some keys in the right-hand side to get the harmony effect. For Types
06–26, turning auto accompaniment on or off has no effect. However, it is necessary
to play two notes simultaneously for Types 06–12.
