Note On and
Note Off
This is the most important MIDI message. It determines the pitch and velocity of
a generated note. A note-on message will start a note. Its pitch is derived from
the note number, which can range from 0 to 127. The velocity lies between 1 and
127. A velocity value of 0 is equivalent to a note-off message.
Normalize Normalization is a function to raise the level of a sample to its maximum (0 dB)
without causing distortion. This function automatically searches a sample for its
maximum level and consequently raises the entire sample’s level until the
previously determined maximum level reaches 0 dB. In general this results in a
higher overall volume of the sample.
Panning
The process or the result of changing a signal’s position within the stereo
panorama.
Pitch-Bend
Pitch-bend is a MIDI message. Although pitch-bend messages are similar in
function to control change messages, they are a distinct type of message. The
resolution of a pitch-bend message is substantially higher than that of a
conventional controller message. The human ear is exceptionally sensitive to
deviations in pitch, so the higher resolution is used because it relays pitch-bend
information more accurately.
Program
A program is a file that contains a list of all samples to be used, and settings for
each sample (e.g., pad assignments, loop points, pitch tuning, effects, etc.)
MPC’s Program Edit Mode is where you can edit and assign samples. The
software can have a total of 128 programs in a project.
There are two kinds of programs that use samples for their sound source: drum
programs, mostly used for creating drum programs and easy and quick
assigning of samples to a pad, and keygroups programs. With keygroup
programs, you can use one sample (or more) and spread it across two or more
keys and play the sample chromatically over a keyboard. That way, there is no
need to sample every key of, for instance, a piano.
Program Change
These are MIDI messages that select sound programs. Program numbers 1
through 128 can be changed via program change messages.
