Audiomodern Riffer 4

Meet Riffer 4, the next generation of Audiomodern’s acclaimed MIDI sequencer.

For over a decade, Riffer has helped producers turn empty bars into melodies, hooks, basslines, arpeggios, and unexpected musical ideas.

Now rebuilt for a new generation, Riffer 4 gives you even more ways to create, shape, remix, and make every riff your own.

Go from silence to inspiration in seconds.

Choose a key and scale, generate a riff, then shape it exactly the way you want. Adjust its range, density, timing, and feel.

Edit individual notes, explore variations, and turn every generated idea into something uniquely yours.

Five Engines, Five Ways to Create

Riffer 4 features five purpose-built generation engines, each designed with its own musical character.

Create hypnotic sequences, memorable hooks, guitar-inspired patterns, animated arpeggios, and basslines with weight - then reshape, combine, and transform them into entirely new ideas.

A Decade of Riff Creation

Riffer was generating musical ideas long before generative tools became a category.

After 10 years, more than 100,000 users, and millions of generated riffs, Riffer 4 takes the original concept further than ever.

Whether you're starting a new track, escaping a creative block, looking for an unexpected variation, or simply want something new to react to, Riffer 4 keeps ideas moving.
