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.

Release

An envelope parameter. The term "Release" describes the descent rate of an envelope to its

minimum value after a trigger is terminated. The Release phase begins immediately after the

trigger is terminated, regardless of the envelope's current status. For instance, the Release phase

may be initiated during the Attack phase.

Resonance

Resonance or emphasis is an important filter parameter. It emphasizes the frequencies around

the filter cutoff frequency by amplifing them with a narrow bandwidth. This is one of the most

popular methods of manipulating sounds. If you increase the emphasis, i.e., to a level where the

filter enters a state of self-oscillation, it will generate a relatively pure sine waveform.

Root Key

The root key defines the original pitch of a recorded instrument or of a sample. Samples in the

MPC software contain the dedicated root key information. This information will be created

automatically during recording or importing.

Sample

When you tap the pads on your MPC, you can trigger sounds that we call 'samples'. Samples are

digitized snippets of audio that can either be recorded using the recording function of your MPC

software or loaded from the File Browser.

Once a sample is present in the MPC software, it can be manipulated in different ways. For

example, a sample can be trimmed, looped, pitch-shifted or processed, using various effects

offered by the MPC software. When you have finished editing your sample, you can assign it to

one or more drum pads to play it. Samples can be either mono or stereo.

Sample Rate

This is the frequency representing the amount of individual digital sample scans per second that

are taken to capture an analog siginal digitally. For normal CD audio recordings, 44100 samples

per second are used, also written as 44.1 kHz. The MPC offers sampling rates up to 96 kHz.

Sequence

A sequence is the most basic 'building block' of music you can compose on the MPC software.

MIDI information from the MPC’s pads, buttons, and data from your MPC hardware’s Q-Link

knobs controls (or an external keyboard) are recorded to the tracks of a sequence. Each

sequence has 64 tracks and the MPC software can hold up to 128 separate sequences at the

same time.
