Troubleshooting

If the SC-8850 does not function in the way you expect, first check the following
points. If this does not resolve the problem, consult your dealer or a nearby Roland
Service Station (listed at the end of this manual).
Cannot turn the power on
Is the power cable correctly plugged into an outlet and the SC-8850?
The volume level of the instrument connected to Audio
output/input jacks is too low.
Could you be using a connection cable that contains a resistor?
Use a connection cable that does not contain a resistor.
Performance is incorrect when playing back music files carrying
the General MIDI/GS logo
Is the Device ID set to 17? (p.50)
A specific Part does not sound
Is the lowest dot in the bar display off?
Parts for which this dot is off have been muted. Turn Part Mute off. (p.35)
Is the volume level of the Part turned down? (p.32)
Does the MIDI Receive channel of the Part match the MIDI Transmit channel of
the connected MIDI device? (p.145)
Some parts do not sound when you press the [VOLUME] knob
Try restoring the GS basic settings. (p.24)
Check the Prevw Velo setting. (p.63)

you press the [VOLUME] knob.
Make sure that the part level has not been lowered. (p.32)
Make sure that Part Mute has not been turned on. (p.35)
Sometimes the part mode may have been muted during operation. If you would pre-
fer not to search for the muted part, you may simply wish to initialize. (p.24)
A specific keyboard area does not sound
Has the Keyboard Range been set? (p.57)
Sound is heard but the bar indicator does not move
Is the sounding part different than the displayed part group?
If so, press [F1] – [F4] in the Part Basic screen to select the part group that is dis-
played.
Cannot select the desired sound
Are you sending an incorrect Program number? (p.41)
Are you setting the SC-8850 to SC-55 Map, SC-88 Map, or SC-88Pro Map?
