4. Troubleshooting

Power does not turn on

•Is the power cable connected to an AC outlet?

Check the connection (see p.6)

•Is the power switch turned ON?

Make sure that the power switch is ON.

The CX-3 does not respond correctly to MIDI data from an external device

•If you are receiving MIDI exclusive messages, is the “MIDI Rx Sys Exc” parameter set to Ena?

Check the setting of this parameter.

•Does the CX-3 support the message that is being transmitted?

Operating a pedal switch or expression pedal

No sound

•Are the other devices or headphones connected

correctly?
Check the connections	(see p.6)

•Is the power of your amp or mixer turned on?

•Is the [MASTER LEVEL] knob raised?

•Is the Global mode Group 4 “MIDI Local” parameter turned On?

Check the setting of this parameter.

•Are the bars of Drawbar 1 or 2 pulled out? Pull out some of the bars.

Moving the bars does not affect the sound

•Is the setting of the DRAWBAR SELECT section

correct?

If you wish to play using the bars, select UPPER [DRAWBAR 1] or UPPER [DRAWBAR 2]. ....... (see p.8)

Percussion is not applied

•Is the setting of the DRAWBAR SELECT section correct?

If you wish to use the keys of the percussion section, select UPPER [DRAWBAR 2] in the DRAWBAR

SELECT section (see p.11)

•Is the Normal Edit mode “DB Preset’s Perc” param-

eter set to Ena?
Check the setting of this parameter	(see p.11)

•Are the percussion-related parameters set correctly? The percussion “soft” value is determined by adding

the Normal Edit mode “Percussion Normal Level” parameter value to the “Percussion Soft Offset” parameter value. If the sum is less than 0, no percus-

sion will be heard (see p.18)

Rotary speaker effect is not applied

•Is the amp selection correct?

Select either Type 1 or Type 2 for the Normal Edit mode or EX Edit mode Group 4 “Amp Type” param- eter. If you select Pre Amp, the rotary speaker cannot be used.

The CX-3 does not respond to MIDI data from an external device

•Is the MIDI cable connected correctly?

Check the connection (see p.27)

•Is the global MIDI channel set correctly? Check the setting.

connected to the rear panel does not produce the intended operation

•Have you selected Pedal 1 or Pedal 2 for the Global mode Group 1 “Prog Up Ctrl” or “Prog Down Ctrl” parameters?

It is possible to assign multiple functions to a pedal switch or expression pedal. However if a pedal switch etc. is assigned to the Global mode Group 1 “Prog Up Ctrl” or “Prog Down Ctrl” parameter, the Global setting will take priority, and the setting of Normal Edit mode or EX Edit mode will be ignored. Check the settings of these parameters.

Unexpected things occur when the CX-3 is connected to an external MIDI device

•Is there a CC# conflict?

The CX-3 can transmit most of the operations of its front panel keys and drawbars etc. as control change numbers. This means that with the factory settings, some of the control change numbers will conflict with standard MIDI devices, and when the CX-3 is con- nected via MIDI to other devices, these control changes will coincide with different functions on the other device, producing unexpected results.

Check the Global mode Group 6 and 7 CC# param- eters, and turn off unneeded parameters or change their CC#.
