ABLETON MIDI EDITING
Adjust MIDI velocity
and note length in Ableton sets.
Describe an edit to a small .als file while keeping pitches and note starts fixed. Confirm the range, review each change, and download a candidate.
Supported input: .als up to 300 KB · up to 256 MIDI notes · at most one MIDI clip per track.
Edits adjust velocity and duration. Note starts, pitch, tempo, audio and plugins are not edited. Ableton opening and playback have not yet been verified.
Selecting a file uploads it for inspection. Sessions are saved in this browser. Read our file-processing policy before uploading.
The sample demonstrates MIDI changes using generated XML. Your original file stays unchanged. Download important candidates before clearing browser data.
