Petri – Generative Sample Player


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 8×8 matrix editor.

Petri operates in demo mode until you pay the registration fee.  The program is fully functional so you can make sure it works on your system before purchasing.  The unlocked and demo versions are identical in features except that the demo mode produces a 2 second sine wave burst around every 30 seconds until you register.  Make sure you use a valid email address when buying the app, or there will be no way to send you a serial code!

How did this project use Max?

Max is responsible for Petri's existence, and the countless smiles on my face for around a decade.
