AlgoRhythmia is a drum machine and random MIDI drumbeat generator. It generates patterns up to 4 measures long in any of six time signatures and at virtually any BPM. It allows the user to mutate or regenerate any or all of the drum sounds in a pattern and includes the ability to play .wav samples. It includes a library of royalty-free .wav samples and allows the user to edit the individual notes in a drum pattern. Patterns can be saved to disk or exported to a MIDI file.
