Expanding
"Connecting Other MIDI Devices"
[Objective]
The rear panel of the GR - 1 is equipped with both MIDI IN and
MIDI OUT
connectors.
Using MIDI gives you a lot of very
practical capabilities: using the guitar to control an external
sound module, or the other way around, using the GR - | as an
additional
sound
module
for a keyboard
or sequencer.
This
section is about expanding your MIDI system.
@ What is MIDI?
MID! stands for Musical Instrument Digital Interface, a world-wide standard for data
transfer
between
digital
musical
instruments
and
computers.
A
MIDI-compatible
instrument can read and undersiand patch switching messages or performance data sent
from another MIDI instrument, even if they are completely different models or made by
different
manufacturers.
So
for example,
you
could
use
a guitar
synth
made
by
Manufacturer A to play Manufacturer B's sound module, and use them together to enter
|
data into a sequencer made by Manufacturer C.
|
The GR - 1 uses MIDI messages to transmit information about:
The
pitch of a note that has been played, and with what kind of attack (Note On
messages);
QWhen string vibrations have decayed beyond a certain point (Note Off messages);
Continuous
changes in pitch, such as from string bends, vibrato arm, slides, etc.
(Bend messages};
Patch
switching, or Tone switching when
we're talking about a multi-timbral part
1
(Program Change messages); and
|
Changes in volume and effects of all types (Control Change messages).
i
These are just a few of the many different kinds of messages.
