2 Power Supply
e Dry batteries |
This unit can be powered by six D size (SUM-1/R20P) manganese dry cell bat-
teries. Weakened batteries will result in lower volume or poor tonal quality.
The power indicator lamp will gradually lose its brightness when battery
power weakens. At this time, change batteries or shift to one of the alter-
nate power sources mentioned below. |
Battery replacement: | | ,
4
(@) Open the battery compartment cover on the bottom of the unit and take
out used batteries. | | ee
(2) Load new batteries taking care that polarity is correct. .
* It is advisable to replace all six batteries at the same time for longer battery life. ;
* Standard battery life is approximately 6 hours. |
¢ Car battery
With the car battery adaptor (CA-5, optional), DC power is supplied from
a car battery through the cigarette lighter socket.
An AC adaptor (AD-5, optional) is required when using household current. Use
only a genuine CASIO adaptor with the same voltage rating (100, 117, 220, or 240)
as the power supply in your area to prevent component damage. Plug the AC
adaptor into the AC outlet and the cord into the unit. This will automatically
cut off the battery power supplly. ° : Be ag 3 |

Dynamic Bass System
* Refer to the general guide found on page 4-5 for exact locations of this keyboard controls and
connections.
The MT-640 equipped with Casio's innovative “Dynamic Bass System” for
rich, powerful bass response. In addition to full-range stereo speakers on
the front panel, a “super woofer” is located on the bottom of the MT-640. And
the MT-640 body is designed to act as a speaker cabinet, as bass sounds are
channeled through internal sound ducts and output through twin ports as well
as from the bottom of the unit. This results in dynamic, multi-directional bass
sounds.
+
¢ Dynamic Bass Volume Slider
You can adjust the volume of the “Dynamic Bass” sound independently, to
gain just the right effect for the type of music you're playing. |
¢ Dynamic Bass Level Indicators
The MT-640 features a linear bar indicator located on the front panel, which
shows the volume level of the dynamic bass sound.

types of chords more easily. Playing of the chords is simplified as shown

e Pressing one of the accompaniment keyboard keys produces a major
chord corresponding to that note.
¢ Simultaneously pressing any key to the right (two keys at the same time)
results in a minor chord.
¢ Similarly, pressing one more key to the right (three keys in all) produces
a seventh chord, and pressing the fourth key to the right (four keys
in all) creates a minor seventh chord.

MIDI clock messages (see 1).

11-9 Using the MT-640 as a MIDI percussion sound source
When either of the “Percussion” tones are selected as a MIDI timbre, you can
use the MT-640 as a MIDI percussion sound source. (Refer to page 9-10 for details
on percussion sound key assignments.)
When channel 4 is used as a fourth voice instead of MIDI clock message trans-
mission, try selecting one of the percussion tones for this channel. In this way,
you can create original rhythm patterns using a sequencer.
* When you select Percussion 71 for a MIDI timbre, the reception of the note number 85 through
90 causes “opened triangle” to sound.
* When you select Percussion 2 for a MIDI timbre, the reception of the note number 85 through
90 causes “typewriter bell” to sound.
11-10 Using Drum Pads in the MIDI mode ;
When the Chord/MID! selector is set to “MIDI”, percussion sounds assigned
to the channel select pads (Quijada, Voice, Wind Chime, Orchestra Hit) do not
sound. Other percussion pads operate normally, however.
e Percussion Pad MIDI Transmission
When the MT-640 is set to transmit, the percussion pads trigger transmis-
sion of the following MIDI note numbers.
HI TOM: 96 CRASH SYMBAL: 93
MID TOM: 95 HI AGOGO: 92 ;
LOW TOM: 94 LOW AGOGO: 91 .
e Percussion Pad MID! Reception
When the MT-640 is set to receive, pad sounds are triggered upon reception
of the note numbers listed above.
11-11 Additional preset tones in the MIDI mode
The following tones can be utilized when receiving MIDI program numbers 20
through 29.
