From a quick melody to a full arrangement, ToneScribe Pro handles it all with powerful on-device machine learning.
ToneScribe Pro uses an on-device machine learning model. Works anywhere — no Wi-Fi, no servers, no cloud. Your audio never leaves your iPhone.
Preview your MIDI with Piano, Strings, Synth, Guitar, Flute, and more — instantly, without leaving the app.
Automatically identifies the musical key of your audio and suggests top alternates, so you know what scale you're working in.
Save standard .mid files to your library, share them to GarageBand, Logic Pro, Ableton, or any DAW via the Files app.
All your converted MIDI files in one place. Browse, replay, and export whenever you need them.
Optimized for speed. Most tracks process in under 30 seconds on modern iPhones — no network round-trip, no waiting.
How It Works
Pick any audio file from your Files app — voice memo, recording, or music.
ToneScribe Pro's on-device machine learning model analyzes pitch, timing, and velocity right on your iPhone.
Preview with any instrument, save to your library, and share the .mid file straight to your DAW.
No accounts, no analytics, no tracking SDKs. ToneScribe Pro does not collect any personal data. Your audio is yours alone.
