This tool exports Renoise song data as a .json file to be imported into Unreal Engine 4 as a Data Table. Importing into UE4 requires a customised set of Structs to interpret the file contents into the Data Table format. Unreal doesn't allow the importing of .xml files, so songs can't be loaded into it directly from a Renoise song (.xrns). This tool extracts only the data that will be useful, though exactly what that is will change over time as the tool is developed.
Exported data includes all tracks, patterns, automation, song sequencing and tempo. There's also support for Pattern Matrix track muting, sequencer text, track/column names and track colours.
