Tuning the
MIDI Guitar
Your CASIO MIDI Guitar fea-
tures built-in electronic tuning
circuitry which makes it easy to
stay in tune without the aid of
pitch pipes, external strobe tuners
or other instruments.
Also, you may need to make fine
octave tuning adjustments at the
bridge assembly if certain strings
seem difficult to tune. These
adjustments are made individually
for each string.
s The Basics
To tune your guitar
(DSelect the frequency of the
standard pitch (A4).
Before actually tuning your
guitar strings, you can use
microswitches number 8 and 9
on the back of the guitar to
select the frequency of the
standard pitch you will tune to.
This is simply a basis to work
from when you tune your guitar
— if one note is in tune you
can tune the others to ir.
As with other instruments, the
MIDI guitar uses A4 as the
standard pitch. You can specify
the frequency of A4 by turning
the microswitches ON or OFF
according to the chart shown on
the right. |
(2)Tune each string by using
the tuning indicators,
Notice that there ate two arrows
which light up when you play
an open string on the guitar,
These are the runing indicators.
One is marked “ 4” indicating
that the open string being
played is sharp, and the other is
marked “b” indicating that the
open string being played is flat.
When these indicators light
simultaneousiy, the string is 1n
tune (within +3 cents).

The microswitches and MIDI sen-
sitivity controls on the back of
the guitar are protected by black
rubber covers, These controls are
made up of precision electronic
components which may be
damaged 1f exposed to statte elec-
tricity or foreign elements, so be
sure to replace the rubber covers
after making any adjustment.
Lights ro indicate that
A: “*—— the string is sharp
> y 4 Lights to indicate that
the string is flat
If two or more strings are played
simultaneously, both the “4”
and “b” indicators will not hight.
You can tune each string by play-
ing it open or at the octave (12th
fret). For increased accuracy, you
might find it best to tune each
string open first, then check the
tuning at the 12th fret and make
any necessary fine adjustment,
(Tune the MIDI sound source
to the MG Series guitar,
la order to play totally “in
tune,” your MIDI sound source
should be tuned to the MIDI
guitar. You might also try to de-
tune one or the other for some
interesting effects.
To adjust octave tuning
* Play the string open and then
at the octave (12th fret).
e If the pitch is slightly sh
at the 12 fret, turn the cor.
responding bridge adjustment
screw slightly to the left (A)
and check open/octave tuning
e If the pitch is slightly flat at
the 12th frer, turn the corres-
ponding bridge adjustment
screw slightly to the right (B)
and check open/octave tuning
I's important to note that each
time à string's pitch is rated 550
cents over is standard tuning, the
tuner automatically “shifts” into
the next octave. © |
Because of this, if a string is dl-
ready sharp (when the “#" тай
cator 15 lit) and yon continue to -
raise ts tuning, the “bh” indicator
will fight and the “Y” mdicator
will go out, This is because you
have exceeded the 550 cent limit
and the tuner is indicating tuning
for the next octave up, ©
The Basics 6
Supplying Power
to Your Guitar
In addition to being a “normal”
electric guitar, your MG Series
guitar features MIDI circuitry
which requires electricity for
operation. Ш
To power the MIDI guitar, you
can connect an optional AC
adaptor (AD-3), or use 6 AA
(SUM-3) batteties. When you're
not using your guitar as a MIDI
controller, batteries or AC power
is not necessary.
If the power indicator on the
front panel seems dim when you
tum the „power ON, it’s probably
time to change batteries.
When changing batteries, be sure
to replace all 6 at the same time.
If battery power is too weak, your
guitars MID! functions may
operate abnormaily.

Changing Strings
Change strings whenever they
become worn or lose their brilli-
ance (hopefully before théy be-
come corroded or rusty!). You'll
find that fresh strings not only
sound better, they're easier to
keep in tune as well (once
they've gotten past the initial
“stretching” stage). They're also
easier to play than old ones,
When you've finished playing,
be sure to wipe the strings and
frets with a diy cloth to prevent
premature corrosion caused by
hand perspitation.
To change strings
(Dinsert the string through the
appropriate hole in the back of
the guitar so that it is held by
the ball end.
@With the string in proper
position over the bridge and
nut, insert the tip of the string
through the hole in the
machine head post.
(3)“Tie” the string off firmly.
(@)Holding the string fairly taut
with your right hand, wind up
the excess string by turning the
corresponding tuning knob with
the other hand (or try using a
tuning crank). .
(5)Once all strings áre in place,
tune and renine as necessary
using the built-in electronic
tuner. (See page 5 for tuning.)

The Basics 4
The MIDI guitar is capable of
MIDI performances in either
POLY or MONO modes. In the

Performance 8
Normal and
tor, you can select from either the |
NORMAL performance mode or
the CHROMATIC performance
In the normal position, you can
bend the notes of MIDI sounds
in the same way that you bend
normal guitar sounds. In the
chromatic position, MIDI sounds
bend only chromaticaliy — in
half tone increments. -_
Another interesting feature of
chromatic performance is that it
can aid you in staying in tune
when playing only MIDI sounds.
Since all MIDI sound notes are
sensed chromaticaliy in this
mode, notes played on strings
which are slightly out of tune are
“rounded” to the nearest half
tone and output “in tune.”
Naturally, the chromatic setting
only effects MIDI sounds — gui-
tar sounds are output jus as the
strings are tuned in all cases:

In the POLY mode, normal
MIDI bend is only possible on
one siring al a time. If you at-
tempt to bend two or more
strings at once, MIDI sounds
bend only chromatically.
Mixing MIDI and
Guitar Sounds
By using the MIDI/Guitar seiec-
tor, you can mix both MIDI and
Guitar sounds, or play either
sound independently.
With some MIDI timbres, you
may find it useful to mix in the
Guitar sound to pick up the tni-
tial string attack, which is a bit
delayed when output only as a
MIDI sound. Or you may want to
play straight guitar in some cases,
of even straight MIDI sounds.
By experimenting with various
MIDI timbres and mixes, you'll
be able to create a wide range of
unique sounds and effects.
To play only MIDI
e Move the MIDI/ Guitar selector
into the MIDI position.
You can control the overall
volume of the MIDI sound(s) by
using the MIDI volume control.
Note, however, that this only
works with MIDI instruments or
devices which are capable of
receiving MIDI Control Change
message number 7 (see MIDI Im-
plementation Chart).
If you're performing in the
MONO mode, with more than
one MIDI timbre, you can control
the relative volumes of all voices
by adjusting the output volume
at the MIDI sound source(s).
To play only guitar
sounds |
Move the MIDI/ Guitar selector
into the Guitar position.
You can control the overall
volume and tone of the Guitar
sound(s) by using the guitar
volume and tone controls. If the
MIDI/Guitar selector is switched
to the Guitar position, the MIDI
sound is cut off (a MIDI NOTE
OFF message is sent).
To mix MIDI and guitar
® Move the MIDI/ Guitar selector
into the GUITAR & MIDI
You can mix the relative volumes
of the Guitar and MIDI sounds
by using the guitar and MIDI
volume controls.
MIDI Sound
By using the octave selector, you
can raise of lower the octave of
MIDI sound output.
Making Program
MG Series guitars let you make
“remote” selection of MIDI
voices. You can change the select-
ed MIDI program (voice) number
from the guitar — without hav-
ing to use controls on the MIDI
sound source.
To raise or lower MID!
e In the NORMAL position,
MIDI sounds are output in the
same octave as the guitar sound
(corresponding to normal note
e To raise MIDI sound pitch by
one full octave, move the selector
to the UP position.
e To lower MIDI sound pitch by
one full octave, move the selector
to the DOWN position.
To make program
e Move the Normal/Chromat-
1c/ Program Change selector into
position. (@)
Before making 2 program change,
check to make sure that the pro-
gram change indicator is flashing,
If any strings ate still vibrating,
the Program Change indicator
will not flash. Mute the strings so
thar the indicator flashes,
e With the Program Change 1n-
dicator flashing, finger and play
the note corresponding to the
MIDI Program Number you want
to select. The indicator lights
solid momentarily during Pro-
gram Change registration.
The octave selector setting only
relates to MIDI sounds, and has
no effect on natural gutter
@ Le
If you want to change the select-
ed program number again, mute
the strings so that the indicator
flashes and then play another
note corresponding to the pro-
gram number you want to select.
e Return the selector to the
tion for performance,
Program Change numbers are as-
signed to various strings and frets
as shown in the chart shown
below (®)
Program number assignments
shown in the below chart ® are
only applicable when standard
guitar tuning 15 used
If string bends are made while
making program changes the
Program Change number i
shifted as well.

It’s important to note that MIDI
Program Change numbers are nor
synonymous with “voice” or
“program” numbers on your
MIDI sound source. Naturally,
the program or voice numbering
system for individual Instruments
are different,
MIDI Bend Range
By setting MIDI bend range, you
can establish how far up you can
bend a MIDI sound note when
switch is set to “NORMAL.”
Four different settings are posst-
ble, using microswitches 6 and 7.
The chart listed below (©) shows
an example of the relationship
between Program Change num-
bers and voice numbers when us-
ing the CASIO CZ-1 Digital
Synthesizer as a sound source.
When using other MIDI sound
sources, refer to the MIDI im-
plementation chart which was
supplied with the instrument (or
device). | {

MIDI Pickup
Ín some cases, you'll want to ad-
just the sensitivity of the MIDI
pickup, for individual strings.
When increased, NOTE ON mes-
sages are sent with only a light
touch, as are maximum velocity
messages. When decreased, the
opposite is true.
For example, differences in string
gauge or string height may cause
an imbalance in MIDI sound
À certain string or strings may
stand out, while others seem too
weak or don't sound at the same
time. These problems can be
solved by incteasing ot decreasing
MIDI pickup sensitivity.
In some cases, if you ust sound
sources which feature MIDI

Adjustments 14
Neck Curvature
Your guitar features an
adjustable bolt-on neck, and a
custom wrench (large) 15
provided so you can make your
own adjustments of neck
curvature (if necessary).
These adjustments can be rather
delicate, and are best left to
our local guitar service shop,
owever if necessary, you can
make adjustments according to
the basic rules and procedures
that follows.
15 Adjustments
To adjust neck
(DWith the guitar in normal
tuning, hold down a string at
| both the 1st and 22nd frets
(2)While pressing down the
string at both frets, slide a
playing card under the strings at
the 12th fret.
You should be able to move the
card freely in and out, without it
touching either the frets or string,
however if the distance between
the string and fretboard is over
0.5mm, adjust neck curvature by
turning the adjusting nut
clockwise (toward the 6th string).
If the playing card does not slide
easily between the string and free,
adjust the adjusting nur by
turning it counterclockwise
(toward the 1st string).
Machine Head
By adjusting the torque of the
machine head, you can prevent
strings from becoming detuned
(to some extent). ‘
Adjusting Guitar
Pickup Height
By adjusting pickup height, you
can make delicate adjustments 1n
sound characteristics. When the
pickup 1s brought closer to the
strings (raised), the sound be-
comes fuller, while when the
pickup is lowered the sound be-
comes thinner and sharper.
Adjusting Bridge
Depending on the gauge of
strings you will be using, the
style of music and the type of
sound you want to obtain, you'll
probably want to adjust string
height {distance from the fret-
board and pickups}, by raising or
foweting the bridge for each
string. A special wrench (small) 1s
provided for this purpose.
To adjust machine head
torque -
e Using a Philips screwdriver,
tighten or loosen the screw hold-
ing each tuning knob. Turn to
the left (B) to loosen torque and
to the right (À) to tighten
To adjust pickup
e Turn the screws at both sides
of the pickup(s) to lower or raise
the pickup.
As 2 basic rule, the surface of the
pickups should be between 2 and
3mm from the strings when the
strings ate held down at the 22nd
(top) fret.
To adjust bridge

of malfuncrions or damage.
“© Do not use alcohol, thinner or similar chemicals for cleaning. |
e To preserve the life of strings and frets, always wipe your guitar
with 2 clean, dry cloth after each use.
e When transporting your MID! guitar, always put it in a hard or
soft case for protection. It’s also a good idea to remove the tremolo
arm and loosen strings when transporting your instrument for long
distances. Ca
