Troubleshooting - Yamaha PortaTone Owner's Manual

If MIDI note numbers higher than C#6 are received
when the DRUMS voice is selected (in either the
Remote Control or Multi mode), the corresponding
percussion sounds are produced.
C#6 = Voice "Five"
D#6 = Voice "Six"
F#6 = Voice "Seven"
G#6 = Voice "Eight"
A#6 = Click Lo
C#7 = Click Hi
Data received via the MIDI IN connector is not re-
transmitted via the MIDI OUT connector (i.e. no
echo-back) in either the Remote Control or Multi
mode.

TROUBLESHOOTING

Something not working as it should? In many cases what
appears to be a malfunction can be traced to a simple error that
can be remedied immediately. Before assuming that your
PSR-200/PSR-300 is faulty, please check the following points.
1.
PROBLEM
The PSR-200/PSR-300 speakers produce a "pop" sound
whenever the power is turned ON or OFF.
CHECK
This is normal and is no cause for alarm.
2.
PROBLEM
No sound.
CHECK
Are the MASTER VOLUME control and accompani-
ment volume levels turned up high enough?
3.
PROBLEM
Rhythm won't start or no rhythm sound.
CHECK
Is the accompaniment volume turned up high enough?
Are you sure you pressed the START button?
Perhaps the PSR-200/PSR-300 is in the SYNCHRO
START mode, so all you have to do is start playing.
4.
PROBLEM
Auto accompaniment won't function. No lower key-
board sound.
CHECK
Auto accompaniment won't function if the FINGERED
mode is selected and you're using SINGLE FINGER
type fingering or improper chord fingering.
Are you sure you're playing in the left-hand section of
the keyboard when the FINGERED or SINGLE FIN-
GER mode is selected?
The left-hand section of the keyboard will produce no
sound if synchro start is disengaged in the FINGERED
or SINGLE FINGER mode.
5.
PROBLEM
The accompaniment key changes while you're playing.
CHECK
Perhaps you accidentally pressed a key in the left-hand
range.
6.
PROBLEM
Auto accompaniment chords don't seem to change prop-
erly.
CHECK
Are you playing chords that the PSR-200/PSR-300 can
recognize (see fingering chart on page 19)?
7.
PROBLEM
The sound is distorted or intermittent.
CHECK
In this case, your batteries are probably flat and need
replacement.
