PSR-A1000
• Certain notes sound at the wrong pitch. 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 72).
• Some channels do not properly play back
when playing back song data.
Make sure that playback of the relevant channel(s) is turned on (page 69).
• The Harmony function does not operate. Harmony cannot be used with the Full Keyboard or AI Full Keyboard fingering
modes. Select an appropriate fingering mode (page 59).
• MIDI data is not transmitted or received via
the MIDI terminals, even when MIDI cables
are connected properly.
Make sure the HOST SELECT switch is set to “MIDI” (page 139). The MIDI
terminals cannot be used for the other switch settings.
• When a voice is changed, the previously
selected effect is changed.
Each voice has its own suitable preset values which are automatically recalled
when the corresponding Voice Set parameters are turned on (page 127).
• 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.
This is normal and is a result of the PSR-A1000’s sampling system.
• Some voices will jump an octave in pitch
when played in the upper or lower registers.
This is normal. Some voices have a pitch limit which, when reached, causes this
type of pitch shift.
• Disk save operations take a long time. This is normal. Keep in mind that it takes approximately 1 minute to save 1
megabyte of data to a floppy disk.
• The voice produces excessive noise. Certain voices may produce noise, depending on the Harmonic Content and/or
Brightness settings in the FILTER page of the Mixing Console display
(page 114).
• The sound is distorted or noisy. • 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 115).
• Some filter resonance settings in the Custom Voice Creator display (page 81)
can result in distorted sound. Adjust these settings if necessary.
• A strange “flanging” or “doubling” sound
occurs. Also, the sound is slightly different
each time the keys are played.
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 53) or change the voice for each
part (page 51).
