New users of REAPER will find the following terms helpful to know. Many are specific to REAPER, others are terms common with other DAW software. A more complete, but less friendly list of terms can be found in the Glossary
The Docker provides a tabbed viewing area for several REAPER functions (mixer, FX browser, undo, routing matrix, etc.) and is accessible through the View menu. The Docker can be detached from the main REAPER window and moved, for example, to a secondary monitor. See: Docker
Envelopes allow the automation of volume and pan for each track. Envelope changes are read and applied during recording/playback.
More info: Envelopes
A folder is a track that has other tracks as children. Folders can also contain media items and envelopes. A folder makes a bus for the children (and self), thus you can control all children's volume/pan/mute/solo by using the folders volume/pan/mute/solo.
Gluing items renders (without FX) the selected items on each track to a new single WAV file, which replaces the original items in the project (the original files are left unaltered on disk).
Items (aka "Media Items" or "Media Events") contain audio/MIDI information and reside in a Track. Items can be empty, or have one or more "Takes", one of which is visible and "active". Items are often called 'Parts' in other DAW software.
Markers, like Regions, are used to identify important sections of a song (i.e. Verse, Chorus, Intro, etc.) Unlike Regions, Markers indicate only the begining point of a section and are displayed in the Markers band of the Timeline. Markers are useful for quickly locating and playing a section.
Regions, like Markers, are used to identify sections of a song (i.e. Verse, Chorus, Intro, etc.) Unlike Markers, Regions indicate both the beginning and ending points of a section and are displayed in the Regions band of the Time Ruler. Regions are useful for relocating/duplicating existing sections of a song.
The Routing Matrix provides easy configuration of the routing of each track. REAPER offers routing to any track, folder, and hardware device.
See: Routing Matrix
A stem, in REAPER, is a TRACK that was rendered (or "bounced") from one or more other TRACKS. You can use stems to "freeze" fx on tracks, or to render each/some tracks in a mix (a "stem" as it is called) for exporting. Exporting this way is often done when sending a project to an external mixer or mastering-engineer, and should typical start at 0:00:00 on the timeline.
See: Render track to stem track
A take is a part of an item which contains a media source (audio, MIDI, or other type). An item can have multiple takes, which may refer to different recorded versions (where it gets its name), or if you wish to open a copy in an external editor, or apply fx to the item, etc, it can create the output as a new take (enabling you to go back to other takes at a later date).
When you adjust an item (splitting, adjusting its start/end times, stretching, etc), the action is performed on all takes, so that if you need to switch to a different take, the overall timing is correct.
Track Control Panel
The Track Control Panel, or TCP, is the left-most pane in the main REAPER window. The TCP displays track headers which provide access to the mute, solo, effects, routing, and envelope functions of each track.
Tracks can contain multiple media items and envelopes. Tracks appear as horizontal bars on the Timeline and as verticle bars on the Mixer. REAPER has one type of track that can be used in many ways:
- Standard Tracks: Standard tracks can hold items (audio and midi), envelopes, effects and instruments.
- Folders: Folders hold items, envelopes, and standard tracks (See Folders)
- Stems: Stems is a track rendered (see Stems)
