The S4’s Internal Data Structure​

Structure Overview

Before diving into workflows on the S4, it’s helpful to understand how the device stores and organizes information. This overview explains the relationship between system settings, storage, Projects, Scenes, and Tracks, giving you a clear picture of how your work is structured internally.

System ElementDescription
S4 SystemThe S4 has 4GB of internal storage. All projects stored on the S4 can access any sample. The S4 also stores several configuration settings independently of projects, such as MIDI settings, MISC settings, and the MAIN LEVEL.
External DriveThe S4 can store samples internally, but its storage capacity can be expanded by connecting an external flash drive to store additional samples.
ProjectsA project is the primary container for stored data on the S4, encompassing all 128 available scenes. It also retains all mappings and parameter values from the PERFORM and MIX views, along with their respective sets of four modulators.
ScenesScenes are located directly below projects in the hierarchy. Each scene stores all track-related data on the S4.
TracksTracks store device settings, track-specific modulators, and buffers used in MATERIAL devices such as TAPE and POLY. The S4 provides four tracks in total.
