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
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
❍
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.
When the Human Voice “Jazz Scat” is selected,
playing dynamics do not change the sound
❍
The Utility menu item “Initial Touch” is turned OFF (p.
87).
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
❍
Harmony Intelligence is at ON (p. 41).
❍
Chord Intelligence is turned ON (p. 88).
Automatic Accompaniment sounds odd
❍
The keys for a chord were not pressed simultaneously.
❍
When Chord Intelligence is OFF (p. 88), the chord is not
being pressed correctly.
Pitch is off
❍
Transpose is in effect (p. 48).
❍
The tuning is incorrect (p. 93).
❍
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,

❍
With some music files, the lyrics cannot be displayed

❍
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).
