Troubleshooting - Yamaha CBX-K1XG Owner's Manual

Troubleshooting

Even though the CBX-K1XG is easy to use, it may occa-
sionally not function as you expect it to. If that happens,
check the possible problems and solutions below before
assuming that the instrument is faulty.
(Problem)
— (Possible Cause and Solution)
No sound.
— Controller data, such as Volume, Expression and Master
Volume, may have been set to values too low to produce
sound.
— The Fixed Velocity setting may be too low.
No sound from the built-in speakers.
— Check that a set of headphones is not connected.
— Make sure that Local is set to On. (See page 32.)
No data is sent via MIDI OUT.
— Make sure that the Host Select switch is set to MIDI.
Cannot transmit data to or receive data from a computer
connected to the TO HOST terminal.
— Make sure that the Host Select switch is set appropriately. If
it is to MIDI, communication with the computer is disabled.
(See pages 10 – 11.)
When the power is turned off and on again, the settings you
made have been cancelled.
— This is normal. The CBX-K1XG has no internal memory
backup.
Sound is cut off.
— When incoming active sensing messages exceed that allowed
by the MIDI standard, the sound will automatically be cut off.
A certain function does not respond or work properly.
— The connected MIDI device may not support the relevant
function on the CBX-K1XG.
Specific functions/messages cannot be executed or sent
properly.
— While holding down C in the middle of an operation,
you may have inadvertently released C. Make sure to
hold down C for the duration of the operation.
The connected device does not respond to MIDI clock
messages, or MIDI clock messages are not sent.
— Make sure that the Tempo setting on the CBX-K1XG is set to
a value other than oFF. Also make sure that the connected
device is set properly for receiving MIDI clock messages. If
another device is connected to the MIDI IN of the CBX-
K1XG and that device is sending the MIDI clock messages,
Merge must be set to ON.
The Tempo setting has no effect.
— The Tempo setting is inactive when Tempo is assigned to the
ASSIGNABLE Wheel.
With Merge set to ON, tempo change messages sent from an
external device have no effect.
— If an external device is connected to the MIDI IN of the CBX-
K1XG, and the CBX-K1XG is sending MIDI clock messages,
the external device cannot be used to send MIDI clock
messages.
Sending a bank select message also sends a program change
message.
— This is normal. The CBX-K1XG automatically sends the
currently set program change number together with a bank
select message.
The RPN or NRPN controller number assigned to the ASSIGN-
ABLE Wheel doesn't function properly.
The RPN or NRPN direct data send function doesn't work
properly.
— Please refer to the Merge-related Notes, page 23.
Octave Shift function has no effect.
— Octave Shift cannot be changed while a key is being held
down.
The B lamp flashes, indicating a MIDI buffer full
error.
— A MIDI "loop" may have been set up. To remedy this, set the
MIDI Merge and Local functions to OFF. (See pages 30 and
32.)
— Too much MIDI data (exceeding the receive capability of the
CBX-K1XG) may have been received at MIDI IN.
An "Err" message appears in the LED display.
— The battery power is too low for proper operation. Replace all
batteries.
The keyboard is not touch sensitive.
— Make sure that Fixed Velocity is set to oFF.
The Fixed Velocity setting has no effect.
— The Fixed Velocity setting is inactive when Velocity is
assigned to the ASSIGNABLE Wheel.
Even when Touch Sensitivity is active, the effective velocity
range is narrower than expected.
— Please refer to Footnote #2 on page 32 for details on velocity
range.
The All Sound Off function has no effect.
— All Sound Off in the Group A functions only applies to the
cureently selected MIDI channel.
The rightmost five keys of the keyboard do not sound at the
expected pitch.
— When set to the highest octave range, the rightmost five keys
are set to play notes Gm4 (80) through C5 (84).
