Formed in 2009, the Archive Team (not to be confused with the archive.org Archive-It Team) is a rogue archivist collective dedicated to saving copies of rapidly dying or deleted websites for the sake of history and digital heritage. The group is 100% composed of volunteers and interested parties, and has expanded into a large amount of related projects for saving online and digital history.

* What is this? sf2xrni is a Renoise tool for creating XRNI (instrument) files from a SoundFont sf2 file. * Usage $ (mono) sf2xrni(.exe) sf2-files For mono, you'll need mono 2.8 or later. When you run the tool, a directory is created to contain a set of XRNI files. e.g. for file "foo.sf2" it will create directory "foo". * Conversion Basics A soundfont file contains more than one Presets. A Preset is mapped to an XRN Instrument. A SF2 Preset contains more than one Instruments. An Instrument contains more than one Zones, and each Zone contains a SampleHeader, which is a set of information to retrieve raw sample. BaseNote is set from OverridingRootKey, or OriginalPitch. LoopMode is set from SampleModes. LoopStart/LoopEnd are set from those in SampleHeader. Resulting samples are sorted in KeyRange order and bound to SplitMap. * Dependencies sf2xrni uses a couple of libraries: - NRenoiseTools, to write XRNI files. http://www.codeplex.com/nrenoisetools - NAudio, which contains SoundFont2 file format support. http://naudio.codeplex.com/ - ICSharpCode.SharpZipLib. It is just NRenoiseTools dependency http://www.icsharpcode.net/OpenSource/SharpZipLib/Default.aspx The prebuilt assemblies are in the repo. Note that I didn't copy NAudio.dll from NRenoiseTools release binaries since 0.1.3. It is because the NAudio version in NRenoiseTools misses some required bits used by sf2xrni. I have imported it from NAudio project itself.
