Loading and saving Dr. Octo Rex patches

Loading and saving Dr. Octo Rex patches is done in the same way as in other patch based devices - see “Loading patches” and “Saving patches”.

Dr. Octo Rex patches can consist of up to eight separate REX loops. When you load an Dr. Octo Rex patch, the REX loop(s) will be automatically loaded in the Loop Slots with their names shown in the display(s) below each button.

•	You can also load Dr. Octo Rex patches by dragging them from the Browser and dropping on the device panel.

About the Dr. Octo Rex patch format

Dr. Octo Rex patches (.drex) contains all panel and synth parameter settings as well as references to all (up to eight) REX loops. The actual REX files are not contained in the patch but must be available separately on the computer.

About opening songs that previously used Dr. Rex devices

Songs created in earlier versions of Reason that used Dr. Rex devices will open just fine in this version of Reason. Any Dr. Rex devices will be replaced by Dr. Octo Rex devices and the corresponding REX loop will load in Loop Slot 1. The original Dr. Rex device settings will be translated as follows:

•	The panel parameter settings are automatically applied to the Dr. Octo Rex device.

This makes the loop play back and sound exactly like it did when you created it in Dr. Rex.

•	The Enable Loop Playback button on Dr. Octo Rex will be set to Off.

•	Any automation for Level and Transpose are converted to Master Level and Global Transpose.

•	Routing to CV Mod Input Level is routed to Master Volume.

•	The Dr. Octo Rex is set to “Master Keyboard Input to Slices” Mode, so that it behaves exactly like the old Dr. Rex.
