Problem
When the YPR-50 is turned on or off, a popping
sound is temporarily produced.
When using a mobile phone, noise is produced.
The sound of the voices or rhythms seems unusual
or strange.
There is no sound even when the keyboard is played
or when a Song is being played back.
Not all notes are heard when playing a number of
notes simultaneously.
The sound of the voice changes from note to note.
Possible Cause and Solution
This is normal and indicates that the YPR-50 is
receiving electrical power.
Using a mobile phone in close proximity to the YPR-50
may produce interference. To prevent this, turn off the
mobile phone or use it further away from the YPR-50.
The battery power is too low. Replace the batteries.
(See page 8.)
Check that nothing is connected to the
PHONES/OUTPUT jack on the rear panel. When a set
of headphones is plugged into this jack, no sound is
output.
Too many keys are pressed at the same time. The YPR-50
is polyphonic up to a maximum of 32 notes.
The AWM tone generation method uses multiple
recordings (samples) of an instrument across the range
of the keyboard; thus, the actual sound of the voice
may be slightly different from note to note.
