saturation A term most commonly associated with a slight tape distortion or the characteristics of tube amplifiers. It basically describes a very high gain level that causes a slight distortion of the incoming signal, resulting in a warm, rounded sound. scale A group of related musical notes (or pitches) that forms the basis of the melody and harmony in a piece of music. The most common scales are the major scale and minor scale. scan code Each key on a computer keyboard has a scan code rather than an ASCII symbol associated with it. As an example: The Plus and Minus keys on the numeric keypad and the corresponding keys above the keyboard have a different scan code, but use the same ASCII symbol. scene marker Logic Express can automatically extract information from (abrupt) transitions in QuickTime movie files, and create a marker, making the process of scoring to film much faster and easier. Such transitions in video generally indicate a scene change. Score Editor Logic Express editor that deals with standard musical notation. MIDI note events are represented as quavers, crotchets, minims, and so on. The Score Editor allows you to adjust and edit the layout of the score, and print it. score set A collection of various staff styles, staffs, and other elements shown in the Score Editor can be saved as a score set. This facility allows you to quickly switch between (and edit and print) different portions of the score, such as a brass section, in isolation to the entire score. It also simplifies experimentation with different layouts. screenset A layout of various windows, inclusive of all display parameters (zoom, position, size of each window, and so on) is called a screenset. You can swap between different screensets, much as you might swap between different computer monitors. scroll bar and scroller Gray beam at the edge of a window. A movable box inside the beam is used to select the displayed project section in the window. SDII Sound Designer II audio file format. Very similar in structure to the AIFF file format. search field In many Logic Express windows you find a field with rounded corners and a magnifying glass to the left. This field allows you to perform text searches. As examples, the search fields in the Key Commands window or Loop Browser. self-oscillation Self-oscillation is a typical characteristic of analog filter circuits. It occurs when the filter, at high-resonance values, feeds back into itself and begins to oscillate at its natural frequency. semitone Smallest interval between two pitches in the standard diatonic scale, equal to a half tone. A semitone is also called a half step or half tone. 1286 Glossary
