**Taud Sample and Instrument Image Format (.tsii)**
Created by CuriousTorvald on 2026-06-15
This is a file format for storing sample+inst image only, intended for multiple Taud Pattern Images (.tpif) that share a same samples.
Endianness: Little
# Conformance language
Identical to **Taud serialisation format**.
# File Structure
\x1F T S V M a u d
[HEADER]
[SAMPLE+INSTRUMENT BIN IMAGE (GZip or Zstd compressed. Read 4-byte magic to determine)]
[PROJECT DATA] (optional)
[DATA BLOCKS WITH FOURCC HEADER (see Project Data section)]
Basically a specialised "interpretation" of **Taud serialisation format**. The format differs in the following ways:
* Empty song/pattern table. Number of songs is zero
* Version is always `0b10_xxxxxx`, where 'x' follows the expected Taud version
* PROJECT DATA has just enough blocks to represent instruments (ones starting with 'I' or 'S')

Basically a specialised "interpretation" of **Taud serialisation format**. The format differs in the following ways:
* Compressed size of SAMPLE+INST section is zero
* Version is always `0b11_xxxxxx`, where 'x' follows the expected Taud version
* PROJECT DATA has just enough blocks to represent patterns and songs (ones starting with 'p' or 's')
# Intended Use Case
* Converting a collection of MIDI to Taud with single SoundFont for all. SoundFont is translated into .tsii, and MIDI files are translated into .tpif
