Petri is a sample player 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.

Main Features:

• probabilistic randomization -- control how sparse or dense you want your randomized sequences to be
• randomized pitch, sample choice, sequencing, and granular playback makes creating unpredictable percussion loops an effortless walk in a serendipitous park
• load a folder of aif or wavs to populate 8 channels of sequencing
• disengage all randomization to use Petri like a traditional sample player
• familiar 8 x 8 sequence grid enables quick sequence building on the fly
• hot keys for most-used functions allow for easy live performing
• extensive mouse-over hint system, quick start guide, and full manual makes Petri very easy to learn
• signal-rate synced tempo provides accurate timing
• tap-tempo
• auto-filtering with randomization features
• preset saving
• record to disk
