MIDI Maestro Manual
• PC (Program Change) — Also known as a Patch Change, it is a MIDI message
that changes a patch preset on the listening device. There are 128 possible
PC commands (0-127). Unlike CC commands, PC commands do not have
values.
o
For example, a MIDI keyboard may have several patches, or sounds,
for different instruments like Acoustic Piano, Electric Piano, Marimba
etc. On this device, PC:0 could represent a patch like Acoustic Piano,
and PC:1 could represent a patch like Electric Piano.
•
PB (Pitch Bend) — A MIDI message that has a range of 0–16383 (16,384
different values) with a center at 8192. This allows for operating parameters
that need a lot of precision, like volume, pitch modulation, or wetness, for
example.
•
Note On/Off — Much like what it sounds, a Note On command starts the
playback of a MIDI note, while Note Off cuts off the sound.
o
Without a Note Off command, some sounds will never stop playing
back, or will follow their original decay rate and that can make things
sound very messy.
o
Note Off commands are not always needed with percussive sounds.
Adding the Note Off command should not cause any trouble even if
it’s not necessary. If for some reason you’d like to omit sending the
Note Off command, refer to the target device’s MIDI manual to
confirm it is necessary.
o
Middle C (aka C4) is note 60. (61 is C#, 62 is D, so on and so forth)
o
Velocity is measured from 0-127, 0 being so “soft” it probably is not
audible, 127 being as “hard” as the note can sound. Imagine the
difference between a drummer tapping a snare with their drumstick
lightly and them hitting the snare with all their force. Although
velocity and volume are related, they are not the same thing.
