AudioCipher
The text-to-MIDI chord and melody plugin with a built-in MIDI Vault
About AudioCipher
AudioCipher is a desktop app and DAW plugin (VST3, AU, standalone) that turns typed words into MIDI chord progressions and melodies, then stores them alongside audio stems in a searchable MIDI Vault. Version 4.0 combines the text-to-MIDI generator with a local file manager where you tag ideas by key, BPM, genre, instrument, and mood and drag them straight into your DAW. It is sold as a one-time purchase with no subscription.
Pros & Cons
Pros
- One-time purchase with no subscription, unlike most AI music tools
- Deterministic word-to-melody cipher gives repeatable, explainable results you can return to
- Combines idea generation and MIDI/audio file organization in one plugin
- Runs fully offline with files stored locally on your machine
- Works as VST3, AU and standalone across most major DAWs on Windows and macOS
- Drag-and-drop from the Vault straight into DAW tracks speeds up sketching
Cons
- Generated melodies are raw seeds; you still need to edit and arrange them in a piano roll
- No mobile or tablet version, and some DAWs such as Bitwig have had compatibility gaps
- Very few independent user reviews on G2 or similar sites
- No free tier or trial listed on the official site
- Small bootstrapped team, so support and update cadence depend on a handful of people
Key Features
Text-to-MIDI Generator
Type a word or phrase and AudioCipher encodes it into a melody or chord progression using a substitution cipher mapped to the scale you choose; the same word in the same key always yields the same result.
Key, Scale and BPM Controls
Pick any key, choose from 9 scales, and set the tempo before generating MIDI output.
Melody and Chord Modes
Switch the output type between single-line melodies and chord progressions, with chord extensions and closed-harmony voicing.
Rhythm Controls
Fix note durations or randomize rhythm to explore unlimited variations of the same seed word.
MIDI Vault Card Library
Store MIDI and audio files together in bundled cards so ideas and their stems don't get buried in old DAW projects.
Metadata Tagging and Search
Tag cards with key, BPM, genre, instrument and mood, then filter or search to pull up the right idea quickly.
In-App Preview and Drag-to-DAW
Audition audio and MIDI inside the app, then drag files directly onto tracks in Ableton, Logic Pro, FL Studio, Reaper, Studio One, GarageBand and others.
Bulk Import and Collection Sharing
Import and label files in bulk, and export card collections in the .AUCI format to share or back up.
Offline Local Storage
All files are stored locally and the app runs without an internet connection.
AUCI Sample Packs
Optional paid sample packs (including a Beats By Mantra collab) ship in an .AUCI format that loads directly into the MIDI Vault with metadata.
