What's new in Collab

Stem Separation

On-device stem separation powered by Demucs. Separate vocals, drums, bass, and instrumentals from any track without uploading.

• On-device stem separation using Demucs — no audio leaves your machine
• Separate any track into vocals, drums, bass, and other/instrumentals
• Separated stems are automatically organized into stem packs
• Solo and mute individual stems with color-coded waveforms
• Export separated stems as individual audio files

MIDI & Markers

MIDI piano roll visualization, color-coded markers and regions, and drag-and-drop upload improvements.

• MIDI piano roll with 128-note range, velocity shading, and multi-track colors
• Beat grid and tempo map rendering on the piano roll canvas
• Color-coded markers and regions on the waveform timeline
• Point markers and range selections visible to all collaborators
• Improved drag-and-drop upload with progress indicators
• MIDI metadata extraction (tempo, time signature, key, track names)
