Reaper and TouchDesigner are basically ready to communicate with each other out of the box, but many people don't realize how easy this is to setup. You'll have to make sure you chose the optional "ReaRoute" add-on when installing Reaper. Good? Then drag and drop this .tox file into TouchDesigner and we can start using up to 16 different tracks in Reaper to control and infinite amount of parameters in TD, creating dynamic real-time visuals.
On the fence? This will work with the trial/limited versions of both softwares!
Further instructions are inside the ReaRouteTD containers.
