I hear noise.
• When raising the volume using the KEY TOUCH slider, the EQ LOW/MID/HIGH sliders, the VOL-
UME slider or other controls, the levels may become excessive due to digital signal processing,
resulting in a distorted or noisy sound. This is not a malfunction. Adjust this by turning down
the levels for each section.
• When the REVERB/DELAY section is on, the sound may be distorted or noisy due to excessive
input. This is not a malfunction. Adjust this by lowering the sliders in the PART CONTROL sec-
tion and by lowering the value on the Reverb Send edit parameter.
• Some noise may occur when you change the delay effect time. This is because the delay time is
being abruptly changed and becomes non-continuous. This is not a malfunction.
• In certain electrical environments, you may hear noise due to a ground loop or other factors.
This noise may be defeated in some cases by switching the LIFT-GND switch to the LIFT side.
The sliders and buttons aren’t working or can’t be controlled.
• Panel lock might be on (the PANEL LOCK button blinks in this case).
I made a favorite by modifying its program or making other edits, but it’s no
longer there.
• You may have switched to another favorite or turned off the power before saving your favorite.
The damper pedal, expression pedal and foot switch connected to the FOOT
CONTROLLERS jacks don’t work as intended.
• Are you using the correct settings when connecting the pedals? Use the Calibration function to
adjust the polarity and variable range.
MIDI transmit and receive is not working correctly with external devices.
• Are the MIDI cables connected correctly?
• If connecting via USB-MIDI, is the USB cable correctly plugged in to the USB B port?
• Is the Grandstage X set to transmit and receive MIDI data on the same channel as the external
MIDI device?
• Are MIDI messages being transmitted and received that are compatible with the Grandstage X?
The Grandstage X is not responding to MIDI program change messages.
• The Grandstage X supports MIDI program change messages for selecting favorites. However,
the sound programs for MAIN, LAYER and SPLIT cannot be selected using MIDI program
change messages.
The KEY TOUCH slider doesn’t respond to MIDI input.
• The key touch function only works on notes that you play on this keyboard. Dynamics has no
effect on notes received via MIDI IN.
