Initial Audio is giving away a free version of Difro Melody AI, a standalone songwriting and MIDI generation app for Windows and macOS.
Below is a rundown of what the app does, what the free tier includes, and how to grab it.
What Is Initial Audio Difro Melody AI?
Difro Melody AI is a fully offline AI MIDI generator. You feed it a MIDI phrase you already have, and it spins that idea into a practically endless supply of variations. There is no cloud connection and no remote API involved – everything runs locally on your CPU or on a supported GPU.
Getting material into the app is simple: drag and drop a MIDI file, or record a performance straight into the built-in piano roll. From there, hitting Re-Imagine generates a fresh phrase. Anything you like can be dragged directly into your DAW or exported as a WAV file.
The free version ships with 10 prompt models and allows up to 50 generations per month. If you need unlimited generations, the Pro version is $49.
