Glossary
RMS
Short for Root Mean Square. A method of measuring an average of the amplitudes that occur in a
complete cycle of a frequency. RMS is a little over seventy per cent of peak level.
RPN
Registered Parameter Numbers.
See “Controllers, RPNs, NRPNs, and Automation Data” on page 716.
Ruler
Bar showing evenly-spaced measure intervals. It appears in the Track, Staff, and Piano Roll views.
Sampling rate
The number of samples per second a digital audio file is recorded at. A higher sampling rate typically
increases the fidelity recordings, as it helps to avoid phase shifting and aliasing artifacts. A higher
sampling rate will yield larger audio files and more hard drive space used.
Screenset
A snapshot of the current layout of various views and windows in a project, including which windows
are open, their size, position, zoom level and whether they are docked or floating. You can create up
to 10 screensets per project and freely switch between screensets at any time.
See “Screensets” on page 982.
Scrub
A tool used for previewing audio. The Scrub tool allows you to playback audio faster or slower as a
useful auditioning tool.
Sensitivity (window)
Distance from a timing grid a note has to be to be unaffected, or affected less, by quantizing.
Shape
An automation envelope created in the Track view or Console view.
Size
The number of events in a track, listed in the Size column of the Tracks window. This number
changes every time you add or delete events to or from that track.
Slip editing
Non-destructive editing process that allows the start and/or end time of an audio or MIDI clip to be
trimmed by simply dragging the front or back end of the clip.
SMPTE
Society of Motion Picture and Television Engineers. SMPTE format measures time in hours,
minutes, seconds, and frames.
Snapshot
Collection of automation settings that become active at a specific time. When the Now Time reaches
that time, all of those particular settings take effect.
