If the RD-300SX 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.
Problem
Check/Solution
Power Not Coming
On
Is the power cord properly connected? (p.
11)
No Sound
Is the volume level of the RD-300SX (p.
14) or connected device turned all the
way down?
Are all connections properly made?
• When using the RD-300SX as a stand-
alone instrument, be sure to connect
with audio cables or use headphones
(p. 12).
Are sounds audible with headphones
connected?
• If sounds are audible through
headphones, it may indicate that there
is a short in an audio cable or some sort
of amp or mixer problem. Check the
cables and equipment once again.
Is a zone level turned off with the ZONE
LEVEL sliders? (p. 24)
Is the Part setting set to OFF (p. 43)?
If the sound for a pressed key is not being
played, is the Local Switch set to OFF?
• Set the Local Control to ON (p. 46).
Are the effect settings correct?
• Check the ON/OFF settings for MULTI
EFFECTS [ON/OFF] (p. 28), MFX Zone
(p. 40) and level settings (p. 28).
Has the volume been lowered by pedal
operations or by MIDI messages (volume
messages or expression messages)
received from an external MIDI device?
No Sound for
Specific Zone
Is the zone’s volume level turned down?
• Check the ZONE LEVEL sliders (p. 24).
No Sound From the
Connected MIDI
Device
Is the device enabled to transmit MIDI
messages?
• Set [MIDI TX] to ON (p. 47). MIDI
messages cannot be transmitted if
[MIDI TX] is set to OFF.
Is the RD-300SX’s keyboard controller
section MIDI Transmit channel matched
to the connected MIDI device’s MIDI
Receive channel?
• Make the Ch settings screen (p. 47).
No Sound (With a
MIDI Device
Connected)
Is the power to all devices turned on?
Is the MIDI cable connected and plugged
in correctly?
Does the MIDI channel match the
connected instrument? (p. 47)
No Sound From the
Left Side
Is V-LINK switched on (p. 51)?
When V-LINK is switched on, the twelve
keys at the left end of the keyboard are
used to control images, and no sounds
are played with these keys.
No Sound in a
Specific Range
With certain Tones, for example Rhythm
Sets, bass Tones, Timpani, and other
Tones will not sound if a portion of the
Tone falls outside the recommended
range.
Not All Sounds Are
Played
The RD-300SX has a maximum
polyphony of 128 voices. When playing
together with a song or Rhythm along
with heavy use of the damper pedal, the
performance data may exceed the
number of available voices, and as a
result, some notes or sounds played on
the keyboard may not sound.
Tones Are Altered
Did you call up a Setup?
• When a Setup is called up, the current
Tone, effect, and other settings are
disabled, and the selected Setup goes
into effect (p. 34). Save the required
settings to a Setup (p. 35).
Did you press ONE TOUCH [PIANO]?
• When ONE TOUCH [PIANO] is
pressed, the current Tone, effect, and
other settings are disabled, and settings
for use in piano performances go into
effect (p. 18). Save the required settings
to a Setup (p. 35).
