When the project deliverables call for channel-based stems (such as dialogue, music, and effects), use multiple beds to make the needed stems available to the re-renders. In this case, each stem requires a bed and associated objects. Each stem bed will need to be individually assigned to the sends along with the associated objects. Once done, input groups can be defined in the input screen of the Renderer application. In the output screen, groups of stem beds and stem objects can be selected for realtime output or offline re-rendering. Note that the Renderer input/output configuration files (.rmuio) must be saved and loaded to take advantage of this feature to match the Pro Tools session design.
