Troubleshooting
If you’re having difficulty operating the GranTouch, or it doesn’t seem to work as expected,
look up the symptoms in the following table and follow the advice provided.
Symptom Advice
Cannot power up the
GranTouch (the power
indicator is not lit).
Make sure the power cable is connected to an appro-
priate AC wall outlet.
Make sure the power cable is connected to the
GranTouch AC inlet correctly.
Make sure that the POWER switch on the Control Box
is set to the ON position.
A click sound can be heard
when the GranTouch is
powered up and down.
This is normal.
The GranTouch does not
produce any sound.
Make sure that the VOLUME control is turned up (i.e.
not set to minimum).
If a pair of headphones are connected to one of the
HEADPHONE sockets on the Control Box, the piano
sound is not heard through the GranTouch speakers.
Disconnect the headphones.
A rattling sound can be
heard while playing the
GranTouch.
This may be just the sound of the keys.
Make sure that the Pedal Adjuster is set correctly (GT1
and GT2 only).
Cannot hear the reverb
effect.
Make sure that the REVERB control is turned up (i.e.
not set to minimum).
The piano sound has too
much reverb and echo.
Turn down the REVERB control.
The pitch of the GranTouch
does not match other
instruments.
To correct this, set the GranTouch PITCH switch to
match the pitch of the other instrument.
If you cannot match the pitch of another instrument
using the PITCH switch (i.e. the other instrument is
out of the GranTouch’s adjustable range), adjust the
pitch of the other instrument.
With another music source
connected to the AUX IN
connectors, the piano sound
is too loud or too quiet.
You need to balance the volume levels of your
GranTouch and music source. Use the volume controls
on the GranTouch and music source to achieve this.
The GranTouch cannot send
and receive MIDI data with
other MIDI instruments.
Make sure the MIDI cables are connected correctly.
The GranTouch sends and receives MIDI data on MIDI
Channel 1. Make sure the other MIDI device is set to
use MIDI Channel 1.
A Demo song suddenly starts
playing.
The GranTouch is still in Demo Song mode. See
page 10 for details on how to cancel this mode.
