The Synth is effective only when single notes are played. The desired
effect will not be obtained if chords are played.
If your instrument is not tuned correctly, the results may not be as you
expect. In this case, re‐tune your instrument.
If the sound is unpleasantly distorted, lower the “SYN LVL” until the
sound is no longer distorted.
