Randomizer

Apple

Randomizer is a MIDI effect plugin for Logic Pro that randomizes incoming MIDI events in real time. It allows you to apply controlled randomization to various MIDI parameters with adjustable intensity, probability weighting, and range constraints. Use it to add variation and unpredictability to drum patterns, melodies, and other MIDI-driven performances.

Key Features

01Event Type selection for targeting specific MIDI event types
02Input Range sliders with invertible behavior for selective processing
03Amount slider controlling randomization intensity
04Weight slider adjusting probability distribution of randomized values
05Output Offset slider for shifting randomized MIDI output
06Seed parameter for reproducible randomization across bounces

Things to Try

  • 01Set Seed to a specific value when bouncing multiple versions to ensure identical randomization across renders
  • 02Invert Input Range behavior by positioning the lower slider above the upper slider to randomize only values outside your target range
