Troubleshooting - Yamaha PortaTone PSR-130 Owner's Manual

Troubleshooting

Problem
When the PSR-130 is turned on,
a buzzing sound is produced.
The sound is distorted and some-
times cuts out.
Not all notes are heard when
playing a number of notes simul-
taneously.
The sound of the Voice changes
from note to note.
18
Possible
Power is flowing into the PSR-130
Battery power is low.
There is a limit to the number of
notes that can be played at a single
time.
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.
Cause Solution
This is normal and not the result of
a defect
Replace the batteries.
The PSR-130 has a maximum po-
lyphony limit of 12 note. That in-
cludes notes that are not only played
on the keyboard but notes produced
by Style, Song, and Auto Accompa-
niment functions. Therefore, if the
total number of notes simultaneously
produced exceeds the limit, some
notes will be cut off or not sound at
all. (page 11)
