WildMIDI is a simple software midi player which has a core softsynth library that can be used in other applications.

The WildMIDI library uses Gravis Ultrasound patch files to convert MIDI files into audio which is then passed back to the calling application. The library API is designed so that it is easy to include WildMIDI into applications that wish to include MIDI file playback.

CHANGELOG

0.4.6

• A lot of player cleanup and refactoring, thanks to initial work by Azamat H. Hackimov, with addition of several safeguards and minor fixes.
• Ability to choose which audio output backends to include in the build system: see the cmake script for the relevant WANT_??? options. Player's --help command line switch lists the available backends. Thanks to initial work by Azamat H. Hackimov.
• New native audio output backends for player: coreaudio for macOS, sndio for OpenBSD, netbsd (sunaudio) for NetBSD.
• Improved pkg-config file generation in cmake script (bug #236).
• Workaround a link failure on AmigaOS4 with newer SDKs (bug #241).
• Other minor source clean-ups.
• CMake project clean-ups. Cmake v3.4 or newer is now required.

0.4.5

• Fixed MUS drum channels 9 and 15 being swapped if the same file is played twice from the same memory buffer (bug #234).
• Player: Fixed save midi reading wrong argv if there are no path seperators (bug #227).
• Other code and build system clean-ups.

0.4.4

• Fixed integer overflow in midi parser sample count calculation (bug #200).

0.4.3

• New API addition: WildMidi_InitVIO(). It is like WildMidi_Init(), but tells the library to use caller-provided functions for file IO. See wildmidi_lib.h or the man page WildMidi_InitVIO(3) for details. This was suggested and implemented by Christian Breitwieser.

• Fixed a memory leak when freeing a midi (bug #204).
• Fixed slurred/echoy playback at quick tempos on looped instruments (bug #185).
