Not clear what you want to setup. You have 32 RGB strips each 2640 pixels long ?
What will you do with the strips ? Just dispose them in the space without cutting them ? In this case, you have to use the Fixture Editor (from menu Tools) to create a fixture definition of Nx1 pixels with pixel type set to RGB. Then add a fixture in your project and choose this fixture definition, and setup the right DMX address (and the correct DMX interface in Preferences / DMX Out)
