aDrum patch

It is a pattern based drum machine with random functionality. It has four parts (bass drum, snare, close hat and open hat) and each one has 8 pre-designed patterns.

Patterns can be browsed with four knobs so you can combine them and design your unique beat.

In addition it has a clock based random generator that can randomise the choice of the pattern for all the parts or for the one you select.
