Piayer’s Manual
Thank you and congratulations on your choice of a CASIO
MG Series MIDI Guitar. Your new MIDI Guitar lets you
take advantage of the freedom of musical expression pro-
vided by the electric guitar, while making use of the un-
limited sound creation potential of MIDI sound sources such
as digital synthesizers. To obtain optimum performance and
assure long-term reliability, be sure to read this manual
carefully before using your new MG Series Guitar.

Tuning the
MIDI Guitar
Your CASIO MIDI Guitar fea-
tures built-in electronic tuning
circuitry which makes it
stay in tune without apes
pitch pipes, external strobe tuners
of other instruments.
Also, ps0 om fraahatonig oy
lave nts at the
adjustments are made individually
for each string.
5 The Basics
To tune your guitar
(1)Select 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
s¢lect 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 it.
As with other instruments, the
MIDI guitar uses A4 as the
| standard prtch. You can specify
the frequency of A4 by ruming
' the mocroswitches ON or OFF
according to the chart shown on
the nght.
| @Tune each string by using
the tuning indicators
| Notice that there are two arrows
which light up when you play
an open string on the guitar.
These are the tuning indicators.
One is marked “ #" =
that the
played + ohn Fay
marked “b” indicating that the
open string being played is flat.
When these indicators light
simultaneously, the string is in
tune (within +3 cents).

Mixing MIDi and

By using the MIDI/ Guitar selec-
ror, you can mix both MIDI and
Guitar sounds, or play erther
sound independently.
With some MIDI umbres, you
may find it useful to mux in the
Guitar sound to pick up the tni-
tial string attack, which is a bit
delayed when ourput only as a
MIDI sound. Or you may want to
play straight guitar in some cases,
or even straight MIDI sounds.
By experimenting with vanous
MIDI timbres and mixes, you'll
be able to create a wide range of
unique sounds and ettects.
