The RCS programs are designed to allow operators to create and save Scenes and setups. In the case of the M-48, you can configure your Virtual M-48 for a specific M-48 user. Save that setup in the Library. Then change the configuration of your Virtual M-48 for the next M-48 user and save its settings to the Library under a new name. Continue the Configure > Library Save process for each M-48 user. Later, you can Recall each Library setting for each actual M-48 on your Stage.
