Audio Problems
NOTE: When diagnosing audio problems, set the KME61 to play its demo sequence.
If there is no sound from your KME61, check the following:
• KME61 Volume slider moved down. Move the slider to the Up position.
• If a control pedal is plugged in, be sure it is pressed down.
• Volume control on audio system or mixer turned down.
• Signal source selection on audio system or mixer is incorrect.
• Audio cables not securely plugged in at both ends.
• Incorrect type of audio cable.
If you can hear sound but it is low or distorted, look into these possibilities:
• Audio cables not securely plugged in at both ends.
• Low voltage output from power module. Check Power Problems above.
• A received MIDI Volume or Expression message has specified a low volume.
• A control pedal is plugged in but is not pressed down.
• Input to audio system is set for low impedance instead of high impedance.
• Input trim to audio system or mixer is set too low.
MIDI Problems
If you are experiencing problems sending MIDI to an external module, check these:
• MIDI cable not securely plugged in at both ends.
• Wrong MIDI connections. To send MIDI, plug into the KME61’s MIDI Out
connector and the module’s MIDI In connector. Don’t assume; read the jack labels.
• Defective MIDI cable
• MIDI Transmit channel(s) specified by Program Mode or MIDI mode or current
setup does not match that of the receiving device.
If there are problems with the internal sound module receiving MIDI from an external device
like a computer sequencer, try these:
• Transmitting device not sending MIDI on Channel 1.
• MIDI cable not securely plugged in at both ends.
• Wrong MIDI connections. To receive MIDI, plug into the KME61’s MIDI In
connector and the source’s MIDI Out connector.
Prerecorded General MIDI (or GS or XG) sequences may not play through the KME61
correctly. The KME61 is not a General MIDI compatible sound module. These are some of the
differences between the KME61’s internal sound module and a typical General MIDI module:
