Petri

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.

Key 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
