Scaler Music Scaler Detector

Scaler Detector: Free Chord and Scale Detection VST

Scaler Detector is the free chord-detection companion plug-in from Scaler Music. Drop any audio file in — a loop, a sample, a finished track — and Scaler Detector identifies the chords, scale and root key in real time. Use it to sample a record in the right key, remix in a producer’s scale, or write a topline that fits an unfamiliar instrumental.

What’s inside

• Audio-to-chord engine: the same proprietary detection engine that powers Scaler 3, packaged as a standalone listener.
• Standalone + VST3 + AU: run it inside FL Studio, Ableton, Logic, Cubase or by itself.
• Scale + root + chord readout: shows the full chord name (root + quality + extensions) plus the parent scale it sits in.
• MIDI export: drag detected chords out as MIDI clips for editing.

How producers use Scaler Detector

Sampled an old soul record and want to play in the same key? Scaler Detector tells you. Trying to write a hook over a beat your collaborator sent? Scaler Detector identifies the key. Mixing a vocal acapella and need the backing in the same scale? Same answer. It removes the guesswork from working in someone else’s key.

System requirements

Mac (macOS 10.13 or later, Universal Binary) and Windows (Windows 10 or later, 64-bit). VST3, AU and standalone formats.

Questions producers ask

Is Scaler Detector really free? Yes — full free release from Scaler Music, no trial period, no time bomb, no paid upgrade.

Do I need Scaler 3 to use it? No. Detector is standalone — it works without Scaler installed. If you do have Scaler 3, the two integrate.

Will it work on M1/M2/M3 Macs? Yes — Universal Binary, native Apple Silicon support.
