Troubleshooting
 
If the AT-15 does not function in the way you except, first check the following chart. If this does not resolve the problem, consult 
your dealer or a nearby Roland Service Station.
 
When you press the [Power On] switch, the power 
doesn’t come on
 
 
 
No sound is heard
 
 
 
 
Headphones are connected (p. 17).
When you connect the headphones, the sound is heard 
only through the headphones.
 
 
 
 
 
 
You do not have a voice selected (p. 21).
Voices that have their button indicator lit can be played.
 
 
While the [Drum/SFX] button is on (lit), you are playing 
keys in the lower manual to which no drum sounds or 
effect sounds have been assigned (p. 28, p. 103).
 
No sound is heard (when a MIDI instrument is 
connected)
 
 
The power of the connected external devices is not turned 
on (p. 96).
 
Damper Pedal does not operate
 
 
The damper pedal does not affect the Solo voice.
 
 
The damper pedal does not affect the Upper keyboard.
 
Expression Pedal does not operate
 
 
 
Pressing the expression pedal while playing back 
Atelier performance data produces a crackling 
noise
 
 
Is the expression pedal function (p. 83) set to 
“PEDAL+COMPOSER” during playback of Atelier 
performance data? 
When this setting is used, moving the expression pedal 
while playing back Atelier performance data may create a 
difference between the expression pedal information in 
the performance data and the volume as set with the 
expression pedal, which can result in this kind of sound 
being produced.
Set the expression pedal function (p. 83) to “PEDAL” 
during playback.
 
Can’t use the function assigned to the foot switch
 
 
If the Utility menu item “Regist Shift” (change 
Registrations) is “RIGHT” or “LEFT” (p. 87), the foot 
switch will be dedicated to switching the Registration.
 
When the Human Voice “Jazz Scat” is selected, 
playing dynamics do not change the sound
 
 
 
Rotary effect is not be applied
 
 
Some sounds do not allow the rotary effect to be applied 
(p. 102).
 
Even though you press only one key, a multiple 
number of notes sound
 
 
 
 
 
Automatic Accompaniment sounds odd
 
 
The keys for a chord were not pressed simultaneously. 
 
 
 
Pitch is off
 
 
 
 
 
 
While set for an octave shift (p. 27), you are playing keys 
beyond the recommended range. This does not indicate a 
malfunction.
 
Performance data cannot be played back
 
 
While the Utility menu appears in the display (with the 
exception of Channel Mute and Track Mute), playback is 
not allowed. If you wish to playback performance data, 
press the [Utility] button once again to exit the Utility 
menu (p. 78–p. 95).
 
Recording is not possible
 
 
While the Utility menu appears in the display, recording 
is not allowed. If you wish to record performance data, 
press the [Utility] button once again to exit the Utility 
menu (p. 78–p. 95).
 
Lyrics are not indicated properly in the display
 
 
With some music files, the lyrics cannot be displayed 
correctly.
 
 
If you press a button while the lyrics are being shown in 
the display, the lyrics will disappear. To recall them, 
press the [Rec] button. 
 
The recorded performance has disappeared
 
 
Any performance that has been recorded is deleted when 
the power to the unit is turned off. A performance cannot 
be restored once it’s been deleted, so be sure to save it on 
a floppy disk before you turn off the power (p. 73).
