Music

Loops · soundbeds · game music · vocals — all stem-separated

Music Studio delivers full sessions, not mixdowns. Every track ships with four transport-synced stems (drums, bass, keys, pads), a published BPM grid, and mastering to broadcast loudness — so a video editor can pull the hit on the beat and a game engine can swap in a 16-bar variation without re-briefing.

Drag a range on the waveform to regenerate just that section. The rest stays bit-identical. The seam-cleanliness gate runs spectral analysis at the boundary on every section edit — no audible splice ever ships.

Drag a range on the waveform → re-generate just that section. The rest of the mix stays bit-identical. Stems export as four transport-synced tracks.
Honest scope

What it does — and what it doesn’t.

No asterisks. No roadmap claims. Both columns describe shipped behaviour today.

What Music generates
  • Loops, full tracks, soundbeds, game music, instrumental + vocal
  • 4 transport-synced stems on every delivery (drums / bass / keys / pads)
  • WAV + MP3 + MusicXML notation export
  • BPM-locked extension and section regeneration
  • Mastering to -14 LUFS broadcast loudness
What it doesn’t (yet)
  • Render multi-track DAW sessions (Logic / Ableton format)
  • Clone a specific living artist’s voice
  • Score against locked picture (frame-accurate hit-marker auto-cue) — coming PR-F
  • Export per-instrument MIDI (notation only via MusicXML)
Music — one of eleven Studios

Sound that arrives mixed.

Loops, full tracks, soundbeds for video, and game music — delivered with four stems (drums, bass, keys, pads), transport sync, and mastering to broadcast loudness. Drag-select a section to regenerate just that range; the rest stays bit-identical. Most AI music tools give you a mixdown. Accentor gives you a session.

What you can do

Music verbs, shipped today.

Every item below is a real Copilot verb wired into the Studio surface. No roadmap, no asterisks.

REMAKE_SECTION
Remake Section
Drag-select a range on the waveform. Regenerate just that range — the rest stays bit-identical.
EXTEND_TRACK
Extend Track
Add time after a cursor point. Memory of the piece so far carries into the new bars.
REWRITE_SECTION
Rewrite Section
Same range, different instruction. The seam gate runs on the returned boundary.
DELETE_SECTION
Delete Section
Remove a range and close the gap cleanly. The track length updates automatically.
ADJUST_TEMPO
Adjust Tempo
Change BPM without re-rendering. Transport locks to the new grid.
SEPARATE_STEMS
Separate Stems
Split into Drums / Bass / Keys / Pads. Four transport-synced tracks, downloadable.
ADD_LAYER
Add Layer
Add an instrument layer (pad, percussion, riff). The existing mix is untouched.
GENERATE_VOCALS
Generate Vocals
Synthesize a vocal line from lyrics and a voice style. The instrumental is preserved.
EXPORT_NOTATION
Export Notation
Download the score as MusicXML or a rendered SVG via VexFlow.

DELIVERED · MUSIC · CONTINUES TO →
Every delivered track carries stems plus the transport grid — so the video Studio can pull the hit on the beat, and a game can request a 16-bar variation without re-briefing. Every production is visible from Flow, the project-wide board.
