MIDI Generator

What is the MIDI Generator?

Describe the music you want in plain language and the AI writes an actual note sequence: pitches, durations, and timing you can play back in the browser or export as a MIDI file. Because the output is MIDI rather than audio, every note stays editable after you download it.

That distinction matters. An AI song generator hands you a finished mixdown you cannot take apart. A MIDI file drops straight into your DAW, where you can change the key, swap the instrument, fix one wrong note, or keep only the bassline.

How it works

Your description goes to a language model that returns a structured sequence of notes organized into parts (melody, bass, chords). The browser renders that sequence with tone.js, so playback starts immediately without a round trip for audio rendering.

From there you pick a synth voice from the 40+ presets, set the tempo, shape the ADSR envelope, and add reverb, delay, or chorus. Export as MIDI to keep working elsewhere, or as WAV if you just want the audio.

What people use it for

• Getting past a blank project file with a starting melody to react to.
• Generating chord progressions in a genre you do not usually write in.
• Making royalty-free background loops for videos and streams.
• Producing practice material at a specific tempo for an instrument.
• Prototyping a game or app soundtrack before commissioning real composition.

Tips for better results

• Name a genre, a mood, and a tempo: "slow melancholy lo-fi piano, 70 BPM" beats "sad song".
• Ask for a specific part (melody only, bassline only) when you already have the rest.
• Mention a key or scale if the result needs to sit alongside existing material.
• Generate several times and keep the best four bars rather than the whole sequence.
• Export to MIDI and change the instrument in your DAW: the preset here is a preview, not a commitment.
