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
❍
Power cord is not connected correctly (p. 16).
No sound is heard
❍
The [Master Volume] knob is set too low (p. 16).
❍
Headphones are connected (p. 17).
When you connect the headphones, the sound is heard
only through the headphones.
❍
The volume of each Part Balance button is set too low (p.
26).
❍
The volume is set too low on the Expression Pedal (p. 49).
❍
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

❍
The function of the Expression Pedal during recording (p.
82) or the function during playback (p. 83) has been set to
“COMPOSER.”
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.

playing dynamics do not change the sound
