DSPresetConverter

Shared converter core for turning EXS24, SFZ, and SoundFont (SF2) instruments into DecentSampler .dspreset/.dsbundle files. This is the canonical, consolidated version of code that previously existed as separate, drifting copies in DecentSampler, EXS2DS, EXS2ALL, SFZ2DS, and SF22DS.

Status

All five consumers (DecentSampler, SF22DS, EXS2DS, EXS2ALL, SFZ2DS) now build against this repo as a git submodule instead of maintaining local copies.

• Features unique to EXS2ALL (unifyDirectories, truncateLongFilenames, trimOnly, stripMissingImageReferences, _exsFilePath tracking) have been ported forward into this canonical copy.
• The loop-crossfade blend math matches DecentSampler's live playback engine, which is the now the ground truth for crossfade behavior.

Basic Structure

• Source/DSEXS24.{h,cpp} — EXS24 file reader.
• Source/DSSFZ.{h,cpp} — SFZ file reader.
• Source/DSSF2.h — SoundFont (SF2) reader/extractor (DSSF2ImporterCore).
• Source/DSPresetConverter.{h,cpp} — Converts parsed EXS24/SFZ/SF2 data into a DecentSampler ValueTree/XML, plus sample copy/loop-processing/path-rewrite utilities.
