AI Audio-to-MIDI in Ableton Live
Updated May 9, 2026
Audio-to-MIDI transcription is the process of converting a recorded audio file — a vocal phrase, a guitar lick, a piano chord progression, a record-collection sample — into MIDI notes you can edit, re-pitch, re-time, and re-route to any instrument in your DAW. In 2026, the state of the art is deep-learning polyphonic transcription: models that handle multiple simultaneous notes (chords, layered parts, dense pop mixes) cleanly, where traditional pitch-tracking fails.
How do producers do this manually in Ableton?
VIXSOUND ships polyphonic audio-to-MIDI as a native action inside Ableton Live. Drag any audio clip into the chat panel, ask for the transcription, and a new MIDI track appears in your session with the notes written out — ready to be played back through your own synth, sampled, edited, transposed, or re-arranged.
How does VIXSOUND speed this up?
The whole pipeline runs locally on Apple Silicon, so the audio never leaves your Mac, and it pairs naturally with VIXSOUND's stem separation: separate first, transcribe the isolated stem second, get clean MIDI from a song that previously sounded too dense to transcribe.
Three uses producers reach for first
Use 2 · Vocal melody → MIDI
Capture a hummed melody as a synth lead
Hum the melody into your phone. Drag the recording into VIXSOUND. Transcribe. The MIDI clip is ready to be re-played through any lead patch, then quantised, harmonised, or layered as you like.
Use 3 · Stem → MIDI (chained)
From dense mix to editable parts in two prompts
Separate stems first, then transcribe the isolated bass or piano. Polyphonic transcription on a clean stem is dramatically more accurate than on the full mix — this is the workflow that unlocks transcription on real songs.

Frequently asked questions
What is AI audio-to-MIDI?
Audio-to-MIDI transcription converts a recorded audio file — a sample, a vocal melody, a guitar phrase, a piano part — into a MIDI clip you can edit. AI-powered transcription handles polyphonic sources (multiple notes at once) that traditional pitch-tracking can't, and produces clean MIDI even on messy real-world recordings.
How does this work in Ableton Live with VIXSOUND?
Drag any audio clip into the chat panel. Ask: "transcribe this to MIDI." VIXSOUND processes the audio locally, creates a new MIDI track in your session, and writes the notes there. You can then re-route the MIDI to any instrument — your own bass synth, a sampler, an orchestral patch — and edit individual notes like any other MIDI clip.
How does VIXSOUND compare to Melodyne?
Melodyne is the gold standard for surgical pitch and timing editing of pitched audio in place — it's a different tool. VIXSOUND audio-to-MIDI is for transcribing audio to MIDI quickly to re-perform with different sounds. Use Melodyne when you want to fix a vocal in audio. Use VIXSOUND when you want to flip a sampled bassline through your own synth or transcribe a record-collection riff to MIDI for a beat.
What about Ableton's own audio-to-MIDI features (Convert Drums / Harmony / Melody)?
Ableton's built-in conversion is fine for clean monophonic sources — a single guitar line, a clean drum loop. It struggles with polyphonic material (chords, dense mixes) and produces messy MIDI on real-world samples. VIXSOUND uses a deep-learning transcription model trained on polyphonic music, which is meaningfully more accurate on chord progressions, layered guitars, and pianos.
What kinds of audio work best?
Best: clean monophonic instruments (vocals, guitar, bass, lead synth), single-instrument loops, isolated stems. Good: pop song stems after separation, drum loops, simple chord progressions. Harder: heavily distorted material, very fast passages above 16ths at 180+ BPM, reverb-soaked sources, atonal music. The pattern: the cleaner and more tonal the source, the cleaner the MIDI.
What does it cost?
5 credits per transcription. Available on all plans starting at Starter ($9/mo, 500 credits/month). Studio and Ultra include unlimited stem separation, which pairs naturally with audio-to-MIDI: separate first, then transcribe the isolated stem.
