Troubleshooting
The Metronome does not sound during
recording of the User Style
Is the Drum part muted?
Release the mute on the Drum part (p. 63).
The key of the chord shown in the
screen differs from that of the sound
currently being played
Have you set the Key Transpose?
When you have set the Key Transpose (p. 60), the
key of the chord actually being played will be
changed according to what is set, but the key shown
in the screen will remain unchanged.
The progress of the chords will be
different from that of the forms
You might have selected the Style with a different beat.
If you combine a song and style with different beats,
like changing a song with 4/4 beat style into a 3/4
beat style, it cannot be played properly.
