Magenta Studio: Drumify Plugin (Bass2Drum)

Drumify creates grooves based on the rhythm of an arbitrary input. It can be used to generate a drum accompaniment to a bassline or melody, or to create a drum track from a tapped rhythm. It works best with performed inputs, but it can also handle quantized clips.

We used the same dataset of drum performances as Groove to train Drumify. However, instead of learning a translation from quantized drum patterns to performances, here we map from rhythms to performances. We extract a rhythm from each performance by removing the pitches and velocities, while keeping the precise timing details. When you provide an input sequence -- be it a melody, bassline, chord progression, or drum pattern -- we extract a rhythm in the same way and have the model turn it into a groove.
