Chapter4 MIDI
MIDI is an acronym for the Musical Instrument Digital Interface, an industry standard enabling synthesizers, drum machines and other electronic musical instruments to communicate. Through MIDI, the organist can play various instruments from a single keyboard. (The type of data that may be controlled vary with the instruments connected and the depth of MIDI implementation of the manufacturer.)
Connectors
To transmit MIDI data from your XR150 to another MIDI instrument, use an optional cable to connect the MIDI OUT jack of your XR150 to the MIDI IN jack of the other instrument. Make sure that the MIDI "transmit" channels on your XR150 match the MIDI "receive" channels of the other instrument.
To receive MIDI data from another MIDI instrument to your XR150, use a MIDI cable to connect the MIDI OUT jack of the other instrument to the MIDI IN jack of your XR150. Make sure that the MIDI "receive" channels on your XR150 match the MIDI "transmit" channels of the other instrument. MIDI cables should not exceed 15' in length and can be obtained from your local authorized Kawai organ dealer.
Channels
Data cannot be exchanged if the MIDI channels of a transmitting instrument do not match those of a receiving counterpart. The MIDI channels of the XR150 are predefined. When transmitting and receiving MIDI data, the organ always assigns the MIDI channels to the keyboards as follows:
Channel 1: UPPER KEYBOARD
Channel 2: LOWER KEYBOARD
Channel 3: PEDAL KEYBOARD
Channel 10: HAND PERCUSSION
Channel 16: SYSTEM CONTROL CHANGE
The note number that appears when the data of HAND PERCUSSION is exchanged becomes smaller by 1 than the numbers on the table (DRUM ASSIGNMENT) provided on page 17.

Clock can be changed.
In this context, clock means a reference tempo. While holding down the WRITE button, press the down button to toggle the clock mode between Internal and External. When you are connected to an external instrument, select Internal to play to the tempo created by this unit; select External to play to the tempo created by an external MIDI instrument. When you set to External, three dots will appear in the display. While the unit plays rhythm to an external clock, the number of a bar and the time is displayed.
When you set to Internal, starting the rhythm on the unit will send out the MIDI start signal; stopping the rhythm on the unit will send out the MIDI stop signal.

Connection Examples
(Ex. Playing a synthesizer from a keyboard of the organ)
(1) Using a MIDI cable, connect the MIDI OUT terminal on the organ to the MIDI IN on a synthesizer. Then using audio cables, connect the LINE OUT jacks on the synthesizer to the LINE IN jacks on XR150.
(2)Play a note on a keyboard. As long as the synthesizer is configured to receive signals on Channel 1, both the XR150 and the synthesizer will play. This means that both tone colors (XR150 and the synthesizer) will play.
(Ex. Playing XR150 using an external sequencer)
(1) Using a MIDI cable, connect the MIDI IN terminal on the organ to the MIDI OUT terminal on a sequencer so that the sequencer can control the organ.
(2) Make sure that the MIDI "receive" channels on XR150 match MIDI "transmit" channels on the sequencer (Ex. Channel 10 for percussion sounds).
(3)Activate the sequencer. XR150 will start playing as well.
Note: Some data cannot be recognized by XR150. See the MIDI implementation chart at the end of this manual for information on the data that the XR150 can recognize.
Turning off the power or disconnecting the interface cable while sound is being played may cause the receiving instruments to sound continuously. Cut the power to silence the instrument.
(Ex. Playing a drum machine from the organ)
If your MIDI device has the ability to receive clock signals, rhythm tempo of the MIDI device can be played synchronously with the AUTO PLAY ORCHESTRA of the XR 150. A start/stop signal is output from XR150 when you start or stop a rhythm or automatic accompaniment. The tempo is controlled on XR150.
The unit can exchange the PROGRAM REGISTRATION data with an external device.
While holding down the WRITE button, press the up button to transmit the data. "-S-" will appear in the display and the transmission will start.
When the unit detects PROGRAM REGISTRATION data from an external device, it will start receiving the data and "-L-" will flash in the display.

TROUBLE SHOOTING
| Symptom | Check the following |
| 1. The keyboard makes no sound. | When all the lamps on the LOWER/PEDAL CONTROL BLOCK are turned off, the LOWER/PEDAL keyboards makes no sounds.When the VOLUME switches are at their minimum level, the all keyboards make no sound. Set the appropriate volume using the VOLUME switches. |
| 2. The product generates noise. | Motors, neon, or other equipment can be a source of electrical interference creating noise in the sound output. Try changing locations and plug into an outlet that is not being used by devices that draws a lot of current. |
| 3. You can hear the TV or radio sound. | This may happen when there is a broadcasting station near the organ.Consult your KAWAI dealer. |
| 4. The AUTO PLAY ORCHESTRA does not play. | Turn the lamps of the RHYTHM and ACCOMP buttons on to play AUTO PLAY ORCHESTRA. |
