Troubleshooting
When playing the internal sound generator
• No sound
Is the volume set to 0?
➜ Check the SPD-20 volume, and the volume of the amp system and mixer.
Can you here sound through the headphones?
➜ If there is sound through the headphones, the problem may be that a connecting cable is dam-
aged, or there is a problem with the amp or mixer. Check the amplification system and the audio
connections.
Is Layer Off selected?
➜ When Layer Off is selected, the sound from only one side is played.
Could LEVEL in the SOUND parameter group be set to 0?
➜ Set the levels to an appropriate value (p. 23).
Is INST (Instrument Assign) in the SOUND parameter group set to “oFF”?
➜ A pad will not sound if its Instrument Assign parameter is set to “oFF” (p. 22).
Is Local Control turned off?
➜ If Local Control is turned off, the pad section is disconnected from the sound generator, so play-
ing the Pads will not produce sound (p. 72).
Is CURVE (Velocity Curve) in the SOUND parameter group inappropriate?
➜ Make appropriate settings for the Velocity Curve parameter (p. 24).
• No power/Power on, but unit does not operate
Are you using the supplied AC adaptor?
➜ Other AC adaptors may not work properly. If the SPD-20 does not operate even with the correct
AC adaptor, check whether the correct AC line voltage is being supplied.
It is best to avoid connecting many devices of high power consumption to the same AC outlet, or using
an excessive number of AC outlet expansion plugs.
• The volume is too low
Is the volume turned down?
➜ Check the SPD-20 volume, and the volume of the amp system and/or mixer.
Are LEVEL in the SOUND parameter group set too low?
➜ Set the LEVEL to appropriate levels (p. 23).
Is CURVE (Velocity Curve) in the SOUND parameter group inappropriate?
➜ Make appropriate settings for the Velocity Curve parameter(p. 24).
Is SENS (Velocity Sens) in the MIDI parameter group set too low?
➜ Make appropriate settings for the Velocity Sensitivity parameter.
• The sound is wrong
Are the SOUND parameters set correctly?
➜ Modify the SOUND parameters (p. 22).
