Apple Logic Express 9 - Manual (Page 1288)

SMPTE ruler In addition to the standard bar/beat display, the Logic Express Bar ruler can
display time units in SMPTE format: hours, minutes, seconds, and frames, and can display
time code if a video is imported into the project.
Snap pop-up menu A pop-up menu found in the local menu of linear editing windows.
It determines the behavior of regions or events when edited; lengths and cuts will snap
to the nearest possible position (as determined by the chosen Snap menu value), for
example.
software instrument Software counterpart to hardware samplers or synthesizer modules,
or acoustic sound sources such as drumkits or guitars. The sounds generated by software
instruments are calculated by the computer processor, and played via the audio interface
outputs. Often colloquially called softsynths or softsamplers.
solo A way to temporarily highlight one or more tracks or regions or events, allowing
them to be heard in isolation.
Solo tool Click-holding individual regions or events with the Solo tool temporarily allows
them to be heard in isolation. All other objects are muted.
S/P-DIF Short for Sony/Philips Digital Interface, a standard transmission format for
professional stereo digital audio signals. The format is similar to AES/EBU, but uses 75 ohm
coaxial or optical connectors and cabling. Depending on the type of devices involved,
AES/EBU and S/P-DIF coaxial interfaces can communicate directly. Most digital audio
interfaces available today will feature S/P-DIF connectors.
split channel audio files Each channel of multi-channel audio files (stereo) are usually
dealt with together. These files are said to be interleaved. Edits to one channel will affect
the others equally. Logic Express allows you to separate these files, making them split
channel audio files, enabling independent edits to each. Also see interleaved audio file.
SPP Abbreviation for Song Position Pointer, a MIDI clock timing pulse sub-message that
indicates the current “song” (project) position. It is accurate to bars (and beats for some
devices), but is not as accurate as MIDI Time Code (MTC). If you have a choice of these
two when synchronizing Logic Express, choose MTC (see both the MIDI Clock and MTC
entries).
staff style A staff style determines the appearance of notation on a musical staff. You
can define note sizing and spacing, number of staff lines, fonts, and more for each staff
style.
