Jevthoven

What it does

Jev chooses instruments, harmony, and bar patterns for a composition you can refine in a piano roll and export as MIDI.

How you can use it

Start by writing a one-sentence description of your song, naming its mood, tempo, and instruments. Once a developer sets up the software, you type your prompt into the web studio to create tracks, adjust notes on a visual grid, and download standard music files.

You can test the studio for free using pre-programmed musical choices. Composing fresh, original songs in live mode requires connecting the app to a paid TypeSafe account, which charges for each musical decision it makes.
