Sample player and drum machine.


Petri is a sample player & drum machine that generates its own sequences and selects up to eight random samples from a folder of your choosing. It was designed to create glitchy, IDM-inspired drum patterns very quickly. More than simply creating randomized sequences, Petri uses a series of probability algorithms that respond to however sparse or dense you would like the patterns to be, simply by dragging a slider. If you prefer, all randomization can be turned off, and Petri can instead be used as a traditional sample player with sequences input by hand using a familiar 8x8 matrix editor. With a quick-start guide built into the program, mouse-over hints over most features, and a full manual, you'll be creating patterns that rival your favorite electronic musicians in no time.
