Working with big sessions in Revoice Pro can get complex to manage. The addition of process groups in the recent 4.1 update makes this a lot easier. 

When you create one or more APT processes, you can add them to a process group. Changing the setting or the preset of one process in the group updates the settings for all processes in the group. Group playback control temporarily mutes all other audio in the session, making it simple to audition the changes made in process groups. 

In this free video tutorial, brought to you with the support of SynchroArts, see how process groups and track groups are used to manage, process, and control, different sections of a large vocal arrangement.
