Preset vs Cue in Congo
On Congo consoles, content such as stage "looks" are recorded into presets. Presets then can be put in the desired order in a sequence. Similar to using iTunes for creating playlists from songs in your library, presets can be used multiple times in the same sequence or used only once like a traditional cue stack on other consoles.
Cues are an addtional layer of abstraction that does not exist in the Congo software.
