DEM0NHUB [ SKILLS FOR CLAUDE ]

midi-rip

BY @BAT — 14 DOWNLOADS — AUDIO

Extract MIDI from any audio file using Spotify's basic-pitch model. Polyphonic transcription — works on full mixes, melodies, chord stabs, vocal loops. Outputs .mid (drop into Ableton/FL/Logic), MusicXML, and a CSV of (note, start, end, velocity, pitch_bend). Use when the user asks to "rip the MIDI", "transcribe to MIDI", "get the chords from this", "convert audio to MIDI", "what notes are in this loop", or wants to pull a melody/chord progression out of a sample for a beat.

midi-rip

Audio → MIDI via Spotify's basic-pitch (polyphonic, transformer-based, way better than monophonic pitch trackers).

Basic

python3 ~/.claude/skills/midi-rip/scripts/rip.py --input loop.wav
# → loop_midi/  (loop.mid, loop.csv, loop.musicxml)

YouTube / SoundCloud URL

python3 ~/.claude/skills/midi-rip/scripts/rip.py --input "https://youtu.be/XXX"
# auto-downloads via yt-dlp, then transcribes

Tighter / looser detection

python3 ~/.claude/skills/midi-rip/scripts/rip.py --input clip.mp3 \
  --onset 0.3 --frame 0.3 --min-note 80
# --onset (default 0.5)   — onset threshold; lower = more notes detected
# --frame (default 0.3)   — frame threshold; lower = longer / more sustained notes
# --min-note (default 60) — minimum note length in ms

Drop the MIDI into your DAW

The output .mid works in Ableton, FL Studio, Logic, Bitwig, Reaper. The CSV has the same data as a plain table for analysis.

Pairs well with

  • stems → split first, then rip MIDI from the isolated melody/bass for cleaner results
  • cook-app / samplette → drop the ripped MIDI as a sample-flip starting point
  • engine-fux → similar idea, different source

First-run install

Auto-installs basic-pitch + yt-dlp. First run downloads the model (~50MB). ffmpeg expected on PATH.

Notes

  • For best results on full mixes: run stems first, rip MIDI from individual stems
  • Drum tracks won't transcribe well — basic-pitch is built for pitched content
  • Vocal loops actually work surprisingly well
