Stems built for the DJ booth, not just the studio.
Automatic BPM & key detection
Displayed alongside every exported stem — no separate analysis tool needed before beatmatching.
Acapella-only quick export
Skip straight to just the vocal stem for mashups, without waiting on drum/bass/other stems you don’t need.
Loop-safe trimming
Stems export with clean start/end points at zero-crossings, so they loop cleanly in a live set.
Upload the track
Whatever you want to remix or mash up.
Select DJ mode
Get BPM/key detection alongside your stem selection.
Export what you need
Acapella-only for a quick mashup, or full stems for a deeper remix.
Why generic stems aren’t enough for live mixing
A perfectly separated acapella is only half the job if you don’t know what key and tempo it’s in — you can’t beatmatch or harmonically mix it against your next track without that information, and detecting both by ear under time pressure isn’t realistic when prepping a set. Pro/Studio adds Camelot wheel notation alongside standard key notation, for harmonic mixing software compatibility.
Common uses
Live mashups, bootleg remixes, transition edits between tracks in different keys, and pulling acapella hooks for a set.
- How accurate is BPM/key detection on tracks with tempo changes mid-song?
- Detection reflects the dominant tempo/key across the track; for a deliberate mid-track key change, verify by ear for the modulated section.
- Can I batch-process a whole crate of tracks for BPM/key info without pulling stems?
- Yes — DJ mode supports analysis-only exports that return BPM/key without generating stem audio.
