Introduction to MIDI |527
There are various messages, but here are the most commonly used ones:
MIDI Message CC# Meaning
Note On This message instructs an instrument to play a note on a spe-
cic channel. Notes have both a name (C4 standing for the
center C) and a number (60 being the equivalent for C4). A
Note Off message is used to say the note has been released.
Together with the Note On message, a Velocity value is always
sent. This value tells the instrument how loud the note must
play.
Pitch Bend (PB) You can generate this message acting on the joystick (X direc-
tion). The pitch is ‘bent’ up or down.
Program Change (PC) When you select a Sound, a Program Change message is
generated on the channel. Use this message, together with
Control Change #00 and #32, to remotely select Pa5X data
from a sequencer or a master keyboard.
Control Change (CC) This is a wide array of messages, controlling most of the in-
strument parameters. Some examples:
Bank Select MSB 00 This message pair is used to select a Sound Bank. Together
with the Program Change message, they are used to select
a Sound.
Bank Select LSB 32
Modulation 01 This is the equivalent of pressing up the joystick. A vibrato
effect is usually triggered on.
Volume 07 Use this controller to set the channel’s volume.
Pan 10 This one sets the channel’s position on the stereo front.
Expression 11 Use this controller to set the relative volume of a track, with
the maximum value matching the current setting of the CC07
control.
Damper Pedal 64 Use this control to simulate the Damper pedal.
Tempo
Tempo is a global MIDI message, that is not tied to a particular channel. Each MIDI
Song includes Tempo data.
Lyrics
Lyric Meta Events are intended to display text together with the music. Pa5X can
read many of the available Lyrics format on the market.
