Basic Pitch

⬇️ Download

Converts any audio clip to a MIDI clip using Spotify's Basic Pitch neural network for polyphonic pitch detection. Runs entirely offline — no external software or internet connection required.

Features

• Polyphonic transcription — Detects multiple simultaneous notes from pitched instruments
• Works in both views — Session View (same clip slot) and Arrangement View (same position)
• Pitch bend support — Fine-grained pitch contour is captured and included in the output
• Fully offline — The ML model runs locally; no data leaves your machine
• Cross-platform — Works on both macOS and Windows

Usage

1. Right-click any Audio Clip in Session or Arrangement View.
2. Choose Convert to MIDI.
3. A progress dialog appears while the model runs. During transcription the bar runs in indeterminate mode — the neural network is CPU-bound, so processing time scales with clip length and your machine's processing power.
4. A new MIDI track is created next to the original, containing the transcribed notes.

The resulting clip is named <original clip name> (Basic Pitch) and placed at the same position as the source clip. Best results on single-instrument recordings with clear pitch content (guitar, piano, voice, bass).

Note on Arrangement clips: audio is rendered pre-FX from the timeline before transcription. Session clips are read from their source sample. Samples stored in Ableton's compressed format can't be decoded directly from Session — move the clip to the Arrangement and convert there.
