Troubleshooting

■Error Indications

When an incorrect operation is performed, or when an operation cannot be carried out correctly, the VK-8 will light all of its indicators for a few seconds. Errors are divided into two categories—those that show up at power-up, and those that occur during normal operation. Please read the following explanations carefully, and take the appropriate action.

When you turn on the power

All indicators light for several seconds

Cause: The content of backup memory has been returned to the condition it was in originally, when the unit left the factory. In most cases, this occurs when the power was turned off while data was being written into memory.

During normal operation

All indicators light for several seconds

Cause 1: A MIDI cable was disconnected or broken.

Action: Make sure that the MIDI cable is connected correctly.

Cause 2: A large amount of MIDI data was received all at once.

Action: Reduce the amount of MIDI data that is being transmitted to the VK-8.

Cause 3: System exclusive data was not received correctly.

Action: Check the settings of the transmitting device, or the data that is being transmitted.
