The REX File Format

Rex Logo REX is the native file format of ReCycle. A REX file contains the original audio of the loop, the slices you have applied in ReCycle, and any effects or processing you have added in ReCycle. REX files are also compressed, using a non-lossy compression technique to save some precious hard drive space.

The Dr. Octo Rex and REX Files in Reason

Dr. Octo Rex Recycle The Dr. Octo Rex Loop Player is a unique machine that has become one of the cornerstones in Reason’s intuitive musical workflow. It plays loops treated by Propellerhead Software’s ReCycle and its design enables some truly creative ways to use ReCycled loops.

When you open a new ReCycled loop in Dr. Octo Rex you can load up the corresponding MIDI data in a special REX editor in the sequencer where you can move the slices around to create the beats you want. This way you can take a drum loop and rearrange it any way you want.

REX files as audio

You can also use your REX files in as audio by importing them directly onto Audio Tracks in Reason’s sequencer. When you import a REX file as audio, it is automatically stretched to fit the tempo of your Record song.
