Troubleshooting

If you experience problems, please see the relevant
item and take the appropriate measures.
Power supply
Power does not turn on
 Is the AC adapter connected to an outlet? p. 11
 Is the rear panel POWER switch turned on? p. 11

Display

The power is turned on, but nothing is shown
on the display. The microSTATION functions
normally when you play the keyboard or
perform other operations.
 Use the rear panel Contrast adjustment knob to
adjust the contrast of the display. p. 4
The power is turned on, but the display does
not work normally, or an error message is
displayed. There is no sound when you play
the keyboard, and the microSTATION does
not function normally.
 This type of problem may occur if a data writing
operation to internal memory was not completed
correctly, for example, if the power of the
microSTATION was turned off while a program or
other data was being written. If this occurs,
initialize the microSTATION's internal memory.
("Initialization" on page 63)
Can't switch modes or pages
 If you're doing any of the following, you may not be
able to change modes or switch to a different page:
 Recording or playing back a song.
In Combination, or Sequencer modes, you
can't edit the value of Timbre/Track
parameters
 Some parameters can't be edited while notes are
playing, either locally or from MIDI. If the damper
pedal is held down, or if its calibration is incorrect,
notes may be sustaining even if they aren't audible.
 Are you using a damper pedal with a polarity that
does not match the Polarity setting (Global/Media:
Controllers–PEDAL/SW)? PG p. 65
 In some cases, this problem can be solved by
executing the Global/Media mode command
HalfDmpr Calib.PG p. 66
64
Audio output
No sound
 Are connections made correctly to your amp, mixer,
or headphones? p. 12
 Is the connected amp or mixer powered‐on, and is
its volume raised?
 Is Local Control turned on?
 Turn "Local Ctrl" (GLOBAL/MEDIA: MIDI) On.
PG p. 61
 Is the VOLUME knob set to an appropriate
position? p. 2
 Is the Master Volume assigned to Foot Pedal
Assign, and is that pedal volume lowered?
PG p. 65
 If a specific oscillator doesn't sound in program
mode, is its "Play/Mute" set to Play? p. 17
 If a specific timbre doesn't sound in Combination
mode, is its "Play/Mute" set to Play? p. 29
 If a specific track doesn't sound in Sequencer mode,
is its "Play/Mute" set to Play? p. 37
 Make sure that the Status is INT or BTH. p. 29,
p.42
 Are the Key Zone and Velocity Zone set so that
sound will be produced when you play? PG p. 21,
PG p. 22, PG p. 40
 Is the Oscillator, Timbre, or Track level lowered?
PG p. 7, PG p. 19, PG p. 37
 Could the level of the Master Volume following the
total effect have been lowered? PG p. 13, PG p. 26,
PG p. 47
 Could the total polyphony be exceeding the
maximum polyphony of 80 voices?
Notes do not stop
 Is "Hold" (PROG EDIT: OSC Common) turned Off?
PG p. 5
 In Global/Media: Controllers–PEDAL/SW, make
sure that Polarity is set correctly. PG p. 65
 Even if this is set correctly, you might be able to
solve the problem by executing the Global/Media
mode command "HalfDmpr Calib."
 If the ARP ON/OFF buttons are turned on, try
turning them off.
Notes are sounded in duplicate
 Is Local Control turned Off?
 Turn "Local Ctrl" (GLOBAL/MEDIA: MIDI) Off.
PG p. 61
Noise or oscillation is heard
 When using the MIDI/Tempo Sync function to
control the delay time of an effect, noise may occur
in the delay sound. This noise is due to
