590 Glossary
normalize This function applies the current Parameter box settings to the selected
MIDI events (by altering the actual events themselves), and clears the Parameter
settings. When it comes to audio, a different “Normalize” function raises the volume of a
recorded audio file to the maximum digital level without altering the dynamic content.
notch filter This filter type cuts the frequency band directly surrounding the cutoff
frequency and allows all other frequencies to pass.
note number Pitch of a MIDI note, controlled by the first data byte of a MIDI note
event.
Object If capitalized, the term Object is used to refer to the graphical representation of
all elements in Logic’s Environment. These elements can be used to create and process
MIDI data in real-time, and can even be used to create processing “machines“, such as
virtual rhythm generators or step sequencers. Examples for Objects are Instruments,
Multi Instruments, Faders, Arpeggiators and others. In the Environment’s Audio layer
you also find Objects used to process audio data. These Objects are correspondingly
named Audio Objects. Also see Audio Objects.
Object Parameter box The Object Parameter box displays the properties of any
selected Environment Object. In the Arrange window this Parameter box is located
below the Toolbox and displays the properties of the selected Track’s Object.
OMF Abbreviation for Open Media Framework, also known as OMFI—Open Media
Framework Interchange. This file format, typically used for data exchange with
Digidesign ProTools software, can be imported and exported by Logic. The OMF file
format only supports the exchange of audio data (audio media and the usage of this
audio media in a song). MIDI and automation data will simply be ignored when using
Logic’s export function. option 1) Alternative function, often in the form of a checkbox,
sometimes also available as a menu entry. 2) Modifier key, in Windows terminology this
key is also known as Alt key.
oscillator A synthesizer oscillator generates an alternating current, using a selection of
waveforms which contain different amounts of harmonics.
Output Object Audio Object in Logic’s Environment controlling the output level and
pan/balance for each output on your audio interface. They are assigned to a specific
hardware output in their Object Parameter box.
pan, pan position The placement of mono audio signals in the stereo field, by setting
different levels on both sides.
Parameter box Field on the left side of Logic’s windows used to adjust the parameters
of the selected Regions or Objects.
