Riff Expander
מרחיב ריפים
Record a few seconds of a riff and get a full-length track built from it: drums, bass and chords in your key. Free and open source.
Musicians lose ideas because a five-second riff isn't a song yet. Riff Expander keeps your idea and grows it into something you can jam over.
Record or open a riff, trim the loop, and it finds the tempo and key. Pick a style and a length, and it arranges a full track around your riff: intro, verse, chorus, break and outro, with drums, bass and chords that fit. Mix the parts and download a WAV.
