NBSTool is a program which provides some convenient tools to work with .nbs (Open Note Block Studio) files.

---

Features

• Work with multiple files;
• Open old formats (such as .mcsp2);
• Modify header information and change between versions;
• Arrange notes by instruments;
• Import from MIDI files:
  • Only type 1 MIDI files are tested;
  • Support importing note velocity, note panning and note fine-pitch;
  • Allow importing MIDI notes as multiple successive fading-out NBS notes;
  • Can automatically expand distance between notes to fit as many note as possible.
• Import from JSON files;
• Export to other formats:
  • MIDI conversion does not support custom instruments;
  • JSON export files are useful to understand how .nbs files are stored internally;
  • Export to audio:
    • Supported formats: MP3, WAV, OGG and FLAC.
  • Export to Impulse Tracker files (.it) with custom instruments;
  • Exporting to audo and .it files requires ffmpeg to render audio. On Windows, ffmpeg have already been shipped with the program. On Linux, you need to install ffmpeg to use this feature;
  • Datapack export (this is for my personal use, currently not documented).
