Timeline Arranger

The timeline arranger is the main area where the song is composed. It consists of a collection of events, such as regions, positioned against time. Some events (such as regions) will open separate windows for further editing when clicked.


The timeline arranger is split into a top arranger that remains fixed on top and a bottom arranger below it. This way you can pin tracks you want to always be visible at the top.

Arranger Objects

The following arranger objects can exist inside the timeline.


Regions (or clips) are containers for events or data (such as MIDI notes and audio clips - see below) that can be edited in an editor. Regions can be repeated, like below.


The following types of regions exist.

Audio Regions

Audio regions contain audio clips from audio files.


Audio regions belong to track lanes and appear inside Audio tracks.


Double-clicking an audio region will bring up the Audio Editor.

MIDI Regions

MIDI regions contain MIDI notes.


MIDI regions belong to track lanes and appear inside MIDI or Instrument tracks.


Double-clicking a MIDI region will bring up the Piano Roll.

Editing Regions

The following operations apply to regions.


Regions can be repeated, and hence they have editable loop points and a clip start position in the Editor Ruler to modify the looping (repeating) behavior.

Regions can also be looped inside the timeline, by moving the cursor to the bottom-left or bottom-right edge of the region, then clicking and dragging.


Looping (loop-resizing) a region


If the region is already repeated, it cannot be resized anymore until its loop points match exactly the region’s start and end points.


Regions can be renamed by selecting them and pressing F2.

Adjusting Fades

Audio regions can have fades. Fades are gradual increases or decreases in the level of the audio signal, and their positions can be adjusted by clicking and dragging the top left/right corners of the region.


Adjusting fade out point (click & drag)


Adjusting fade out point (drop)

Clicking and dragging the grey part up or down will adjust the curviness of the fade.


Adjusting curviness

The type of fade algorithm used can also be changed by right-clicking on the fade and selecting Fade preset.

The various types of fade algorithms available are illustrated below.
