Before assuming that your PSR330 is faulty, please check the following points. PROBLEM The speakers produce a "pop" sound whenever the power is turned ON or OFF. The volume is reduced or the sound is distorted. The registration memory doesn't work properly. Recorded song data will not play back properly. The display goes bland and all panel controls are reset. No sound when the keyboard is played. Not all simultaneously-played notes sound. Auto Accompaniment seems to "skip" when the keyboard is played. Auto Accompaniment doesn't sound when started. Auto accompaniment won't function properly. No lower keyboard sound. The Harmony function will not turn on. Certain notes sound at the wrong pitch. A cartridge style or song cannot be selected or will not play properly. Operation of the sustain pedal is reversed. Individual registration or song memory data transmitted via bulk dump from an external sequencer or other device is not received by the PSR-330. POSSIBLE CAUSE/SOLUTION This is normal and is no cause for alarm. The batteries probably need to be replaced. Either replace all six batteries, or use an AC power adaptor. The R1/R2/L voice volume settings could be set too low. Make sure the voice volumes are set at appropriate levels (page 58). The Local Control function could be turned off. Make sure Local Control is turned on (page 70). You are probably exceeding the maximum polyphony of the PSR-330. The PSR-330 can play up to 31 notes at the same time - including split, dual, auto-accompaniment, song, and multi pad notes. Notes exceeding this limit will not sound. The MIDI Clock mode may be set to "on". Make sure it is turned "off" (page 70). Make sure that all accompaniment tracks are turned on, and that the they are all set to appropriate volume levels. Make sure you are using fingerings recognized by the selected fingering mode, and are playing in the Auto Accompaniment section of the keyboard. Are you sure you're playing in the Auto-Accompaniment section of the keyboard? Make sure that the Auto Accompaniment split point is set appropriately (page 27). Are you playing chords that the PSR-330 can recognize (see chord types on page 29~)? Harmony cannot be turned on when the FULL KEYBOARD fingering mode is selected or if a percussion kit voice is selected. Select an appropriate fingering mode or voice. Make sure that the scale tuning value for those notes is set to "0" (page 64). Make sure that an appropriate Yamaha Music Cartridge is properly plugged into the cartridge slot (page 55), or the cartridge contacts are dirty. Try re-inserting the cartridge. If the contacts are dirty removing and inserting the cartridge several times will sometimes solve the problem. If this doesn't work, try wiping the cartridge connectors carefully with a soft, dry cloth. Sustain pedal operation will be reversed if you turn on the power or plug in the pedal while pressing the pedal. For normal operation turn off the power then turn it back on while the pedal is not pressed. Transmit the data with no more than a 2-second break between blocks, or transmit as entirely separate data. 73
