■ What is MIDI?
MIDI is an acronym that stands for Musical
Instrument Digital Interface, which allows
electronic musical instruments to “communicate”
with each other, by sending and receiving
compatible Note, Control Change, Program
Change and various other types of MIDI data, or
messages.
■ MIDI Messages Received by the
MU10
The MU10 is controlled by various types of
incoming MIDI messages which automatically
determine play mode, select MIDI channels,
Voices and effects, change parameter values, and
of course play the Voices specified for the various
Parts—complete with all the subtle nuances and
powerful dynamics of expression that the
composer originally intended. Below is an
explanation of the various types of MIDI messages
which the MU10 can receive.
● Key On/Key Off
Key On/Key Off messages, also called Note
messages, tell the MU10 which notes to play, the
Velocity value (depending on how hard the keys
are struck) at which to play them, and how long to
play them—i.e., when to start (On) and stop (Off)
playing each note.
● Control Change
Control Change messages let you select a Voice
bank, control volume, panning, modulation,
portamento time, brightness and various other
controller parameters, through specific Control
Change numbers which correspond to each of the
various parameters.
About MIDI
● Program Change
Program Change messages tell the MU10 which
Voice to select for each Part. You can insert
Program Change messages at any desired location
in a song. Combining Bank Select numbers let you
select various Voices from the hundreds of Voices
available in the MU10.
● Pitch Bend
Pitch Bend messages are continuous controller
messages that allow the pitch of designated notes
to be raised or lowered by a specified amount over
a specified duration.
● Channel Aftertouch
Channel Aftertouch is a pressure sensing function
which lets you control various functions by how
hard you press the keys, over the entire channel.
● Polyphonic Aftertouch
Polyphonic Aftertouch is a pressure sensing
function which lets you control various functions
by how hard you press the keys, for each
individual key.
● System Exclusive
System Exclusive messages control various
functions of the MU10, including master volume
and master tuning, play mode (XG or TG300B),
effect type and various other parameters specifi-
cally related to the MU10.
