Glossary

When an app or manual term is unfamiliar, check the definition here. The definitions describe how each term is used in Miaou.
For a shorter first-read explanation, start with DAW Basics. For complete feature coverage, use the Feature Index.


How to Use the Glossary
If a term is confusing during a task, first decide which kind of object you are editing:
| Object type | Words you will usually see |
|---|---|
| Timeline | Track, region, clip, chord block, marker, playhead, grid, snap, split, loop, Trim Start. |
| MIDI editor | MIDI region, MIDI clip, note, velocity, Piano Roll, drum lanes, computer keyboard. |
| Audio region | Source BPM, Follow project tempo, stretch mode, fades, clip gain, tempo markers, media. |
| Mix path | Effect, send, bus, routing, Track Effects, Master Effects, sidechain, meter, full mix. |
| Project | Draft, project link, password, version, History, collaboration, export ZIP, stems, unlock. |
| Export ZIP | Download ZIP, project-mix.wav, project.json, media/, stems/, full mix. |
Then use the linked guide when you need the workflow, not only the definition.
Commonly Confused Pairs
| Pair | Difference in practice |
|---|---|
| Track vs region | A track is the horizontal lane and sound path. A region is the block on that lane that plays audio or MIDI at a time. |
| Region vs clip | A region is the timeline placement. A MIDI clip is the underlying note data used by a MIDI region. |
| Audio vs MIDI | Audio is recorded/imported sound. MIDI is notes and controls that need an instrument or drum kit to make sound. |
| Project BPM vs Source BPM | Project BPM drives the song grid. Source BPM is the original tempo of one imported audio region. |
| Follow project tempo vs BPM change | Changing BPM moves MIDI/grid timing. Imported audio stretches only when that region has Follow project tempo enabled. |
| Built-in instrument vs custom sample | A built-in instrument comes from Miaou's sound catalog. A custom sample uses one imported or recorded audio region as the MIDI sound source. |
| Generated MIDI vs manual MIDI | Generated MIDI starts from chords or sections, but it becomes normal editable MIDI. Manual edits stay until you choose to regenerate. |
| Transport loop vs region loop | Transport loop repeats playback over a range. Region loop repeats one region's source or MIDI clip for a longer visible duration. |
| Track Effects vs Master Effects | Track Effects process one source track before routing. Master Effects process the final summed mix. |
| Full mix vs stems | The full mix includes the final Master path. Stems are separate source-track exports and do not include final Master Effects/output controls. |
| Save vs Save version vs Export | Save makes the project link reopenable. Save version creates a recovery point. Export creates files for listening, sharing, or another DAW. |
| Marker vs comment | A marker names a time or section in the song. A comment is a project note attached to the work, not a separate arrangement object. |

Editing and Arrangement
| Term | Meaning in Miaou | Learn more |
|---|---|---|
| Active editor | The surface that receives edit shortcuts: timeline regions, Piano Roll notes, chord blocks, markers, automation, or track headers. | Editing Basics |
| Automation | Time-based movement of a Track Effect or Master Effects parameter. Static faders, pans, sends, mute, and solo save as mix controls. | Automation Lanes |
| Bar | A musical measure. Bars depend on the project tempo and time signature data. | Timeline Editing |
| Beat | A musical time unit inside a bar. Miaou uses beat positions for chords, MIDI, regions, markers, and generation. | DAW Basics |
| Chord block | A block in the Chord Track that stores chord root, quality, extension, bass, inversion, start, and duration. | Chords and Scales |
| Clip | The underlying MIDI note data used by a MIDI region. Duplicated MIDI regions get independent clip IDs. | Editing Basics |
| Comment | A note attached to the project or timeline context for communication or reminders. It is not a separate playable arrangement object. | Markers and Sections |
| Comp | A chosen combination of recorded take slices. In Miaou, comping is done by splitting a loop-recorded audio region and choosing takes per slice. | Takes and Comping |
| Context menu | The right-click menu for the object or surface under the pointer. It often includes paste-here, duplicate, trim, split, or delete. | Editing Basics |
| Analysis confidence | The review signal Miaou stores on analyzed Chord Track blocks to show whether a detected chord needs checking. | Analyze and Generate |
| Generated MIDI | MIDI regions created from Chord Track blocks, marker sections, or generation controls. They are ordinary editable MIDI regions. | Analyze and Generate |
| Grid | The musical spacing used for drawing, nudging, trimming, duplicating, and snapping. | Editing Basics |
| Marker | A timeline label for song structure, notes, navigation, or marker-section generation. | Markers and Sections |
| Playhead | The vertical time cursor that shows where playback starts or what time position an edit refers to. | Timeline Editing |
| Region | A block on the timeline. Audio regions point to audio media; MIDI regions point to MIDI clips. | Audio Regions |
| Region loop | A region setting that repeats the region's source or clip content until the visible region ends. | Editing Basics |
| Regenerate | Rebuild generated MIDI from its saved chord or section source. Regeneration replaces generated notes, so use it deliberately. | Analyze and Generate |
| Ruler | The time strip above the timeline. Click or drag empty ruler space to seek; use the visible loop brace for transport loop edits. | Timeline Editing |
| Selection | The object or group selected for editing. Shortcuts follow the active editor, not every visible selection. | Editing Basics |
| Snap | The rule that decides whether dragged or typed positions land on grid lines. Miaou supports absolute and relative snap modes. | Timeline Editing |
| Split | Cutting selected regions at the playhead into separate editable regions. | Editing Basics |
| Take | One recorded pass, often captured while recording through a transport loop. | Takes and Comping |
| Timeline | The main arrangement area where regions, chord blocks, markers, automation lanes, and the playhead are placed over time. | Timeline Editing |
| Trim Start | A non-destructive audio left-edge trim that hides or reveals the beginning of the source without deleting the media. | Audio Regions |
| Version | A saved recovery point for a project. Versions live in History. | Save, Share, and Export |
