Yamaha PSR-1000 Owner's Manual - Page 161

Troubleshooting Problem • Certain notes sound at the wrong pitch. • Some channels do not properly play back when playing back song data. • If you experience distorted or out-of-tune sound from the Vocal Harmony feature, your vocal microphone may be picking up extraneous sounds (other than your voice) - the Auto Accompaniment sound from the PSR-2000/1000, for example. In particular, bass sounds can cause mistracking of the Vocal Harmony feature (PSR-2000 only). • Appropriate harmony notes are not produced by the Vocal Harmony feature (PSR-2000 only). • The Harmony function does not operate. • The microphone input signal and Vocal Harmony sound (PSR-2000 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 each time the keys are played. Possible Cause and Solution 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 135). Make sure that playback of the relevant channel(s) is turned on (page 78). The solution to this problem is to ensure that as little extraneous sound as possible is picked up by your vocal microphone: • Sing as closely to the microphone as possible. • Use a directional microphone. • Turn down the MASTER VOLUME or volume for each part. • Separate the microphone from the instrument's speakers as much as possible. • Cut the Low band via the 3 Band EQ function in the MICROPHONE SETTING display (page 130). • Increase the microphone input level ("TH.") in the Compressor function from the MICROPHONE SETTING display (page 130). Make sure you are using the appropriate method to specify the harmony notes for the current Vocal Harmony mode. See page 131. Harmony cannot be used with the Full Keyboard or AI Full Keyboard fingering modes. Select an appropriate fingering mode (page 62). This is normal; recording the audio input of the microphone is not possible. Make sure the HOST SELECT switch is set to "MIDI" (page 155). 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 143). This is normal and is a result of the PSR-2000/1000'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 123). • 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 124). • Some filter resonance settings in the Custom Voice Creator display (page 89) can result in distorted sound. Adjust these settings if necessary. • Is the gain of the Low band set too high in the Master Equalizer display (Mixing Console - page 127) ? (PSR-2000 only) 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 56) or change the voice for each part (page 54).
