Stem Export Helper

An Ableton Live extension for quickly muting/unmuting tracks and renaming them in preparation for stem exports. Save multiple named configurations per project and switch between them instantly.

NOTE: Currently the Ableton Extensions SDK does not expose any export functionality, so this cannot export for you. But it can help you mute/unmute different tracks and rename them in preparation for stem exporting.

User Guide

Opening the Extension

Right-click any audio or MIDI track in the Arrangement View and select Stem Export Helper from the context menu.

---

Session Name

At the top of the dialog is a Session field. This ties your configs to a named project so they persist across restarts of Ableton.

• Type a new name to start fresh for a new project.
• Select an existing name from the dropdown to reload a previously saved set of configs.
• The session name is required — Save and Apply are disabled until you enter one.
• When you switch to a different Ableton project (different tracks), the session field automatically clears so you start fresh.

---

Configs

The left panel lists your saved configurations for the current session. Each config stores which tracks are checked (unmuted) and any track renames.

Action	How
Switch config	Click a config in the list
Rename config	Double-click its name
New config	Click + New Config (copies current state)
Delete config	Hover a config and click ×

---

Tracks

The right panel shows all tracks in the current Live Set, grouped by their parent group track.

Action	How
Mute/unmute a track	Check or uncheck it
Rename a track	Double-click its name and press Enter
Select all	Click All
Deselect all	Click None

When you apply a config, checked tracks are unmuted and all others are muted. Track renames are written back into the Live Set.

---

Stale Tracks

If a saved config references a track name that no longer exists in the current project, a warning panel appears at the top of the track list.

For each missing track you can:

• Remap to… — select a current track to replace it. This updates the mapping across all configs in the session at once.
• Delete — remove the entry from this config.

---

Batch Rename

Click Batch Rename at the bottom to expand the rename panel. Operations apply to all checked tracks.

Field	Effect
Find / Replace	Replace text in track names
Prefix	Add text before every name
Suffix	Add text after every name

Regex mode

Check Regex to treat the Find field as a regular expression. The Replace field supports capture group references ($1, $2, …).

Common pattern shortcuts — click any pill to fill in the Find/Replace fields:

Pattern	What it does
Remove numbers	Deletes all digit sequences
Remove leading numbers	Strips numbers at the start of a name
Remove trailing numbers	Strips numbers at the end of a name
Remove parentheses	Removes (…) groups
Trim spaces	Strips leading and trailing whitespace
Collapse spaces	Replaces multiple spaces with one

---

Applying

Button	Effect
Cancel	Close without changes
Save	Persist configs to disk without touching the Live Set
Apply to Live Set	Mute/unmute tracks, apply renames, and save configs

After applying, use File › Export Audio/Video (⌘⇧R / Ctrl⇧R) to render your stems.
