there is a rule which is applied to ensure each device
responds accordingly.
MIDI Channel
This is a very important element of most messages. A
receiver can only respond to incoming messages if its
receive channel is set to the same channel as the one
the sender is using to transmit data. Subsequently, the
sender can address specific receivers individually. MIDI
Channels 1 through 16 are available for this purpose.
MIDI Clock
The MIDI Clock message sets the tempo of a piece of
music. It serves to synchronize processes based on time.
Modulation
A modulation influences or changes a sound-shaping
component via a modulation source. Modulation
sources include envelopes, LFOs or MIDI messages. The
modulation destination is sound-shaping component
such as a filter or a VCA.
Note on / Note off
These are the most important MIDI messages. It sets the
pitch and velocity of every generated note. The time of
arrival is simultaneously the start time of the note. Its
pitch is derived from the note number, which lies bet-
ween 0 and 127. The velocity lies between 1 and 127. A
value of 0 for velocity is similar to "Note Off".
Panning
The process of changing the signal's position within the
stereo panorama.
Pitchbend
Pitchbend is a MIDI message. Although pitchbend mes-
sages are similar in function to control change messages,
they are a distinct type of message. The reason for this
distinction is that the resolution of a pitchbend message
is substantially higher than that of a conventional Con-
troller message. The human ear is exceptionally sensiti-
ve to deviations in pitch, so the higher resolution is used
because it relays pitchbend information more accura-
tely.
Program Change
These are MIDI messages that switch sound programs.
Program numbers 1 through 128 can be changed via
program change messages.
