Edit Tools

When working in each editor or arranger, you will most likely be using the cursor tools provided by Zrythm to create, edit and delete objects. Each cursor signifies a separate tool, and Zrythm offers the following tools.


Select/Stretch Tool

This can be toggled to switch between Select and Stretch.

In Select mode, you can make object selections and create, move, clone and resize objects. This is the most common mode and the most common operations can be accomplished by just using this.

Stretch mode is similar to the Select mode, with the exception that when you resize objects, their contents will be stretched to fit the new size.

Creating Objects

Using the select (default) tool, all objects are created by double clicking inside their corresponding arranger and dragging, then releasing when you are satisfied with the position/size.


Creating a region

Selecting Objects

To select objects, you can either click on them, click in empty space and keep dragging to make a selection, or Control-click to add/remove objects to/from the selection.

Selected objects will have brighter color than non-selected objects.

Moving Objects

Objects are moved by clicking and dragging them around. You can move regions to other tracks if the track types are compatible.


Moving a region

Cloning (Copy-Moving) Objects

Holding down Ctrl while moving objects will allow you to copy-and-move the objects to the new location.

Resizing Objects

Objects that have length, such as regions and MIDI notes, can be resized by clicking and dragging their edges.

On objects that can be repeated, such as regions, moving the cursor on the bottom half of the object will allow you to resize the object by repeating it, instead of just resizing it.


When resizing, already repeated objects can only be repeated. To resize them instead of repeat them, their length must be changed or their clip markers must be moved so that they are not repeated anymore.

Cutting Objects

You can Alt-click inside objects to break them up.

Edit Tool

This tool is used to quickly create or delete objects. While you can still create objects using the Select tool by double clicking and dragging, with the Edit tool this is accomplished by single clicking and dragging, which is more efficient when creating a large number of objects.

Holding down Control while clicking will allow you to create multiple objects in a row (where applicable) with a length specified by the snap settings corresponding to each editor.

Cut Tool

The Cut tool behaves similarly to what is mentioned in Cutting Objects, with the exception that you can just click instead of Alt-clicking.

Erase Tool

Using the Erase tool you can just click on objects to delete them, or click and drag to make a selection, deleting all objects inside it.

Ramp Tool

This tool is currently only used for editing velocities for MIDI notes. You can click and drag in the velocity editor to create velocity ramps.


Audition Tool

This feature is not implemented yet.


Where applicable, hold Shift to bypass snapping.
