Schism Tracker is a free and open-source reimplementation of Impulse Tracker, a program used to create high quality music without the requirements of specialized, expensive equipment, and with a unique "finger feel" that is difficult to replicate in part. The player is based on a highly modified version of the Modplug engine, with a number of bugfixes and changes to improve IT playback.

Where Impulse Tracker was limited to i386-based systems running MS-DOS, Schism Tracker runs on almost any platform that SDL 2 supports. Currently builds are provided for Linux, Mac OS X, and Windows. Most development is currently done on 64-bit Linux. Schism will most likely build on any architecture supported by GCC4 (e.g. alpha, m68k, arm, etc.) but it will probably not be as well-optimized on many systems.

See the wiki for more information.

• Stereo left/right orientation may be reversed in rare cases.
• Performance/scanning can be slow with large SD cards.

Changelog

20260524

• Happy new year!
• Fixed a bunch of performance problems causing ridiculous amounts of CPU usage.
• Fixed MIDI input when multithreading is enabled.
• Fixed a nasty memory leak in the zlib decompressor.
• Fixed import of boobiesqueezed XM files.
• Fixed buffer overrun in 24-bit video scalers.
• Fixed a possible race condition in the timer subsystem, which could result in a thread leak.
• Fixed typing of / and \ on Spanish keyboards.
• Fixed typing tab in the message editor.
• Fixed incorrect writing of AIFF files.
• Fixed copying of pattern data including instrument numbers higher than 99.
• Better import of .mod notes (thanks @0x5742).
• Properly ignore Zxx effects in NNA channels.
• Show arrows in the corners of listboxes when there are more items beyond whats displayed.
• Made the built-in FFT variable width (it will probably not work very well still if the buffer size is not a power of 2).
• Switch cursor shape when leaving a page (thanks @hotgar, #790).
• Added "Hotdog Stand" and "Acid Gas" palettes.
• Big endian ASIO formats now work.
• Added SNES BRR sample loader.
• Fixed Win95 support.
• Fixed negative coordinate wraparound.
• SDL 1.2 hardware video now uses OpenGL or hardware YUV overlays if available.
• Fixed weirdness when combining sdl12-compat and sdl2-compat.
• Removed OS/2 binary builds for now, they are hopelessly broken.
• ASIO drivers can be loaded under Mac OS 9.
• Detect AltiVec support on Mac OS 9.
• Added OpenGL support to Mac OS 9 build. it's way too slow to be considered usable, though.
• Honor gl_bilinear option in very old config files.
• Switch to SDL 1.2 on the Wii and honor current widescreen mode.
• Fix versioning being off by roughly a month.
• Force block screen keyboards on SDL 2 and SDL 3, they do not play well with Schism.
• Limited FPS to screen refresh rate. If it cannot be retrieved it defaults to 60hz.
• Plenty of other smaller things.

20251014

• AIFF exports and saves now include extra metadata like WAV and FLAC; this includes sample loops, autovibrato settings, volume, panning, and the version of Schism used to save the file. For info on how this information is stored, see the aiff_header function in fmt/aiff.c.
• FLAC exports and saves now include ENCODER metadata which stores the version of Schism used to save the file.
• Song exports in all supported formats now save the song title as metadata.
• Implemented S90, S9E, and S9F Modplug extensions.
• Implemented SSE and AVX enhanced versions of some functions, such as sample min/max, providing a huge increase in speed, especially with very large samples.
• Fix non-native-endian signed sample saving (mostly relevant for AIFF).
• Fix sample playback not working when focused on number entries in the Sample List.
• Fix loading of 7-bit Oktalyzer samples.
• Fix a nasty bug where Cxx would get ignored if paired with a pattern loop effect.
• Fix logic bug in the volume ramping portion of the player (regressed in may 2009), which caused some clicking issues with very sudden volume changes.
• Fix the built-in clipboard and system clipboard getting out of sync, especially with Alt-D.
• Fix compilation on very old GCC.
• Respect existing file mode when saving files on POSIX systems.
• Added support for zlib decompression, allowing native loading of gzip-compressed files.
• Added support for loading and saving .sbi (Sound Blaster Instrument) files.
• Reverted Zxx-related changes in 20250825, as they proved to just make things worse.
• Fixed FLAC multi-channel export.
• Fixed buffer overflow under some audio drivers when SDL 3 is used.
• Fixed position display in the info page being completely incorrect on little endian systems.
• OPL: Fix first note played when keyjazzing being ignored.
• D00: Fix a problem where a specially crafted input file could be used to hang or crash Schism.
• D00: Add detection of older D00 files.
• Windows: Combine MIDI in and out ports with the same name, manufacturer ID, and product ID as one duplex port.
• ASIO: The "default" device now tries each driver in order, rather than using the first one in the registry.
• JACK: Fix use-after-free if the JACK daemon fails to start.
• OS X: Fix a hang on older versions when trying to execute hooks (mainly affects PowerPC).
• OS X: Fix flicker between aliased and anti-aliased graphics.
• SDL 1.2/SDL 2: Fix mouse cursor getting completely warped under older SDL versions.
• SDL 1.2: Use color palettes for 8-bit video.
• SDL 1.2: Fix audio failing to initialize when using sdl12-compat in conjunction with sdl2-compat.
