Arps that create motion

Arpeggios turn static chords into rolling, hypnotic movement — a staple of trance, melodic techno and progressive house. Melodrift generates arp patterns with the rhythm and contour to keep a section evolving without you programming every note.

The output is MIDI, so you can run it through any arpeggiator-friendly synth, change the rate, or edit individual notes to taste.

Pair arps with chords and melody

Generate a chord progression first, then create an arp in the same key to sit inside it. Layer a lead melody on top and you have a full, moving arrangement built from a handful of generated parts.
