Patterns are at the heart of producing hip hop, techno and many electronic music styles. With Pattern Mutator you can quickly create sequencer patterns and then mutate them—warping their pitch, timing, note order, and velocity into unlimited variations. Pattern Mutator makes it easy to get ideas going and even easier to take those ideas in new directions.

Just like in classic sequencers, you can input notes step by step or record your idea in real-time, creating a looping pattern in perfect sync with your song. Then use the Mutate parameters to set any changes you want in pitch, rhythm, velocity, and more. Once you click the Mutate button your pattern is mutated into a new semi-random variation, a new take on your idea. Click the button again and it’s a new roll of the dice and a new take on your idea. Pattern Mutator, like all Player MIDI effects, attaches to any instrument in the Reason Rack to give it musical superpowers. You can also set it up to send MIDI to external plugins or hardware devices.

When you create a mutation you like, copy it to one of eight pattern slots and switch between them in your song to build your perfect arrangement. Or go deeper by mutating the resulting mutation for even more extreme variations. You never know exactly where you’ll end up, but that’s what makes it fun.

Patterns can automatically play back in time with your song or you can trigger them from a MIDI keyboard and transpose them on the fly to turn even simple patterns into an improvised live performance.


Use Pattern Mutator to generate MIDI sequences that loop endlessly and mutate them for endless variations, too.
Fully polyphonic with both classic step sequencing and real-time recording.
Save pattern variations and switch between them on the fly.
Trigger and transpose Pattern Mutator from your keyboard to perform patterns live.
Sequence any device in the Reason Rack, or use Pattern Mutator to control your hardware or other plugins via Reason’s MIDI Out Device.

New in 1.0.1

Fixed a bug where Pattern Mutator could crash when dragging transpose with MIDI Transpose turned off.
The Step display now shows the actively playing step in all playback modes.
