Modern trackers often use an instruments.bin as a container for all patches—including the 15 ROM presets plus the user slot. These files are used to calibrate emulation accuracy. For example, the MAME (Multiple Arcade Machine Emulator) team distributed a specific ym2413_instruments.bin to ensure that game rips sounded identical to the arcade hardware.
But most common in retro homebrew: instruments.bin is a padded to 16/32/48 bytes for easy file loading, or indeed 6 different instruments for patch banks.
