Troubleshooting
Problem
• Auto accompaniment chords are recognized
regardless of the split point or where chords
are played on the keyboard.
• Certain notes sound at the wrong pitch.
• Some channels do not properly play back
when playing back song data.
• The Harmony function does not operate.
• The microphone input signal (CVP-205 only)
cannot be recorded.
• MIDI data is not transmitted or received via
the MIDI terminals, even when MIDI cables
are connected properly.
• When a voice is changed, the previously
selected effect is changed.
• There is a slight difference in sound quality
between notes played on the keyboard.
• Some voices have a looping sound.
• Some noise or vibrato is noticeable at higher
pitches, depending upon the voice.
• Some voices will jump an octave in pitch
when played in the upper or lower registers.
• Disk save operations take a long time.
• The voice produces excessive noise.
• The sound is distorted or noisy.
• A strange "flanging" or "doubling" sound
occurs. Also, the sound is slightly different

CVP-205/203
Possible Cause and Solution
This is normal if the fingering mode is set to "Full Keyboard" or "AI Full Keyboard."
If either of these is selected, chords are recognized over the entire range of the
keyboard, irrespective of the split point setting. If desired, select a different
fingering mode (page 63).
The Scale parameter has probably been set to something other than "Equal,"
changing the tuning system of the keyboard. Make sure "Equal" is selected as
the Scale in the Scale Tune page (page 127).
Make sure that playback of the relevant channel(s) is turned on (page 77).
Harmony cannot be used with the Full Keyboard or AI Full Keyboard fingering
modes. Select an appropriate fingering mode (page 63).
This is normal; recording the audio input of the microphone is not possible.
Make sure the HOST SELECT switch is set to "MIDI" (page 147). The MIDI
terminals cannot be used for the other switch settings.
Each voice has its own suitable preset values which are automatically recalled
when the corresponding Voice Set parameters are turned on (page 135).
This is normal and is a result of the Clavinova's sampling system.
This is normal. Some voices have a pitch limit which, when reached, causes this
type of pitch shift.
This is normal. Keep in mind that it takes approximately 1 minute to save 1
megabyte of data to a floppy disk.
Certain voices may produce noise, depending on the Harmonic Content and/or
Brightness settings in the FILTER page of the Mixing Console display
(page 121).
• The volume may be turned up too high. Make sure all relevant volume settings
are appropriate.
• This may be caused by the effects. Try canceling all unnecessary effects,
especially distortion-type effects (page 122).
• Some filter resonance settings in the Custom Voice Creator display (page 91)
can result in distorted sound. Adjust these settings if necessary.
Both the Main and Layer parts are set to "ON," and both parts are set to play the
same voice. Set the Layer part to "OFF" (page 57) or change the voice for each
part (page 55).
