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 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. • Even though a Registration Memory setting containing a User voice is selected, the Open/ Save display shows a Preset voice. • 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 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 62). 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 124). Make sure that playback of the relevant channel(s) is turned on (page 76). 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 144). 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 132). This is normal and is a result of the PF-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; even with the Preset voice shown, the actual sounding voice is the selected User voice. When a User voice is registered to the User drive or floppy disk, the actual registered is: 1) the source Preset voice, and 2) the parameter settings as set in the Sound Creator. When you recall a Registration Memory setting containing a User voice, the PF-1000 selects the Preset voice (on which the User voice is based), then applies the relevant parameter settings to it - so that your original User voice is sounded. 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 118). • 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 119). • Some filter resonance settings in the Custom Voice Creator display (page 88) 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 56) or change the voice for each part (page 54). PF-1000 153
