Sample: When you tap the pads on your MPC hardware, 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 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 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 software offers sampling rates up to 96 kHz.

Sequence: A Sequence is the most basic building-block of music you can compose on the software. MIDI

information from your MPC hardware's pads, buttons, and Q-Link Knobs (or an external keyboard) are

recorded to a Sequence. The software can hold up to 128 separate Sequences at the same time.

The length of a Sequence can be set from 1 to 999 bars, which would be enough to create an entire Song

using only one Sequence. However, the software has a dedicated Song Mode that lets you chain

Sequences together to create a Song.

Song: The software has a special Song Mode that allows you to arrange different sections (verse,

chorus, hook, etc.) in order to build a Song. Each Song can have up to 250 parts and the software can

hold 20 Songs in its memory.

Sustain: This term describes the level of an envelope remaining constant after it has passed the Attack

and Decay phases. Once reached, the Sustain level is kept until the trigger is terminated.

Trigger: A trigger is a signal that initiates events. Trigger signals are very diverse. For instance, a MIDI

note or an audio signal can be used as a trigger. The events a trigger can initiate are also very diverse. A

common application for a trigger is its use to start an envelope.
