Glossary
Aftertouch
MIDI property controlling how much pressure is applied after sending a Note On message. See
“Channel aftertouch (ChanAft)” on page 1805 and “Key aftertouch (KeyAft)” on page 1809.
AIFF
Short for Audio Interchange File Format, the audio file format on the Macintosh platform. Files in this
format have the extension .aif or .aiff.
Archive
Silence and suppress the processing of a track. Archived tracks are not loaded into RAM, so they
can’t be unmuted in real time. Use the archive command to reduce the demand on your CPU. See
“Mute” on page 1811.
Arm
Enable a track for recording.
See “Choosing an input” on page 256.
Audio clip
A visual reference to a portion of, or an entire, recorded audio file. This is represented graphically as
a wave form which can be edited and manipulated in a variety of manners.
Audio track
An audio track is a reference point for playing and recording a single digital audio file stored on your
computer's hard drive. The inputs of the audio track are where you would like to record a signal from
and the outputs are where you would like to send this signal to monitor.
Audition
Preview audio effects before applying them to a track.
See “Basic audio processing” on page 765.
Automation
Ability to change controllable parameters over the length of a track. This is achieved by referencing
“snapshots” or “nodes” assigned to specific parameter values in relation to their position on the
timeline and is achieved with envelopes.
See “Quick automation guide” on page 946.
Bank
A means of categorizing sounds. A “bank” can store up to 128 “patches”.
Bit depth
The amount of data allocated to reproducing a sound wave of digital audio file. Closely related to the
dynamic range of the audio file. 1-bit typically represents 6dB of dynamic range when converting an
analog signal to a digital signal. Thus, the greater the bit depth, the greater the dynamic range.
