Parameter Randomizer

A utility device for Ableton Live that lets you randomize and tweak parameters across multiple devices on the same track. Designed for both quick experimentation and precise control, with history, editing, and safety features built in.

Features

• Multi-device support
  Select any device on the track (instruments, effects, plugins). Switch between them without losing history or settings (currently only during the session).
• Randomization with scope
  Turn randomization on or off per parameter, so only the parameters you choose will be affected.
• Parameter edit mode
  • Define Min/Max ranges for randomization.
  • Set a Default value for each parameter.
  • Enter a specific value directly into the table.
• History per device
  Every device has its own undo/redo stack up to 100 steps. Navigate back and forth at any time. (currently not saved in Live Set - just usable during a session).
• Global lock
  Lock the device to block edits and randomization. History navigation remains available while locked.
• Bulk actions
  Apply Min, Max, or Default to all scoped parameters. Randomize all in one click. Toggle All On / All Off for scoping quickly.
• UI designed for speed
  Compact, table-based interface with inline editing. Easy to use for fast experiments, detailed enough for fine control.
• Visual feedback
  • Randomized ON = green, OFF = gray
  • Min/Max/Default show teal if unchanged, red if modified
  • Values are in gray

Planned Features

• Restore configs on project re-opening.

How it works

1. Drop the device on a track.
2. Choose a target device from the dropdown.
3. Mark which parameters should randomize.
4. Set ranges, defaults, or direct values in the table.
5. Press Randomize → explore sounds.
6. Use Undo/Redo to step through variations, or lock the device when performing.

Requirements

• Ableton Live Suite with Max for Live (Live 12 recommended).
• Works on macOS (-> not tested on Windows).

This tool is built for producers and performers who want:

• fast ways to discover new sounds
• precise control over what gets randomized
• safe history to explore without losing ideas
• a clean interface that works both for quick play and detailed tweaking
