New Generative Sample Player For Mac OS X, Petri

Generative music sampler

Sineqube has introduced Petri, a new generative sample player for Mac OS X that creates its own sequences and selects up to eight random samples from a folder of your choosing.

Here’s what the developer, Kevin Holland, has to say about it:

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 8×8 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.

Petri is $30, via Sineqube. Details below.

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.

  1. No MIDI support? If this could sync to MIDI Clock and control external synths as well, It'd be a killer program. Still, as it is it looks pretty cool.

  2. Kevin,

    When controlling an external synth, it would be cool to be able to enter a list of possible MIDI Note numbers and have Petri randomly picking from them. Transmitting random MIDI CCs would be interesting as well. The random sample time could function as a random note-on time.

    Transmitting CC for the built-in filter LFO could be fun too. I'd love to be able to set up a rhythm in Petri with some S&H LFO and have those same S&H steps applied to the filter of another synth used to play pads over it.

  3. Hi ExperimentalSynth,

    I'm emailing you but wanted to respond here as well. Some interesting ideas, and similar to some that I've sketched out for separate applications. It's always a balance between adding features and bloating the program. I do appreciate the input and feedback.

    Hope you are enjoying Petri!
