Troubleshooting
If you perceive any malfunction, check the following sug-
gestions. If the problem persists, contact your nearest Korg
distributor.
Power does not turn on
• Make sure that the AC adapter is properly connected to the
SP-170DX and the AC outlet.
• Make sure that the power LED is illuminated.
No sound from the speakers
• Rotate the VOLUME knob on the rear panel to the right to-
ward MAX.
• The speakers will be muted if the headphones are con-
nected.
Sound is interrupted
• The preset sounds of the SP-170DX have been created by
sampling (recording) sounds of actual musical instru-
ments. When you press a key, some sounds play a single
piece of sampled data, while other sounds play two pieces
of sampled data. The SP-170DX uses two pieces of data for
most of its preset sounds. When one of these two-sample
sounds is selected (regardless of whether the damper pedal
is being pressed), the maximum polyphony is 60 notes.
However, with two Piano sounds, the maximum polyph-
ony is 120 notes. If the maximum polyphony is exceeded,
some of the notes will be lost.
The pitch or tone of the piano sounds wrong in some key re-
gions
• The SP-170DX’s piano sounds replicate the sound of an
actual piano as faithfully as possible. This means that in
some regions of the keyboard, you may feel that the over-
tones seem stronger, or that the tone or pitch seems wrong.
This is not a malfunction.
Pedal is not effective
• Make sure that the pedal cable is properly connected.
Connected MIDI device does not respond to MIDI messages
• Make sure that all MIDI cables are properly connected.
• Make sure that the SP-170DX is transmitting MIDI data on
the same MIDI channel as the connected MIDI device.
