Youphony: 1,824 MIDI patterns built from music theory
A browser-based MIDI composer lets musicians drag named scales, chords, arpeggios, and progressions onto tracks, edit every note, and export the result.
Field notes
The composer assembles arrangements from a bank of 1,824 named scales, chords, arpeggios, and progressions, placing them on tracks for further editing and playback. The page says its notes come from music-theory rules rather than a model trained on recordings, and that projects contain notes and a mix rather than stored audio. Exporting a MIDI file or stem costs 50 credits; new accounts receive 250 credits, while the site states that composing and playing will remain free.
