Step REC

Effortlessly create rhythm patterns using our unique Rhythm Circle System, letting your imagination soar beyond limits.

Rhythm Circle System

The principle of our system is to fractionize a circle by each type of note and visualize your music patterns allowing you to create complex rhythms without effort.

Measure

Imagine each measure like a circle and every circle represents a whole note.

Time Signature

Now split this circle by the number of beats (4/4) resulting in (4) quarter notes to complete a measure.

Fractional Visualization

Each note unit represents a fraction of the circle.

Complex rhythms

Never-ending rhythm pattern exploration (2/4, 3/4, 4/4, 5/4, 6/8, 9/8, 12/8)​, create complex and simple rhythms for your songs.

Error-proofing
