Zrythm has various editors for editing the various events in the Timeline in detail. These editors appear in the Editor tab in the bottom panel.
The Piano Roll, or MIDI Arranger, is the most commonly used editor. It can be used to edit MIDI regions, which contain MIDI notes. When a MIDI Region is selected, the Editor tab will display the Piano Roll, allowing you to edit that region.
In Zrythm, automation is also enclosed in regions (called Automation Regions). This allows automation to be repeated, much like MIDI Regions. The Automation Editor will appear in the Editor tab when an Automation Region is selected.
This is a work in progress
The Chord Editor is used for editing Chord Regions.
