- RtMidi - a set of C++ classes that provides a common API for realtime MIDI input/output across Linux (ALSA), SGI, Macintosh OS X (CoreMidi), and Windows (Multimedia) operating systems.
- By Gary P. Scavone, 2003-2009.
- v1.0.10: (3 June 2009)
- - fix adding timestamp to OS-X sendMessage() function (thanks to John Dey)
- v1.0.9: (30 April 2009)
- - added #ifdef AVOID_TIMESTAMPING to conditionally compile support for event timestamping of ALSA sequencer events. This is useful for programs not needing timestamps, saving valuable system resources.
- - updated functionality in OSX_CORE for getting driver name (thanks to Casey Tucker)
- v1.0.8: (29 January 2009)
- - bug fixes for concatenating segmented sysex messages in ALSA (thanks to Christoph Eckert)
- - update to ALSA sequencer port enumeration (thanks to Pedro Lopez-Cabonillas)
- - bug fixes for concatenating segmented sysex messages in OS-X (thanks to Emmanuel Litzroth)
- - added functionality for naming clients (thanks to Pedro Lopez-Cabonillas and Axel Schmidt)
- - bug fix in Windows when receiving sysex messages if the ignore flag was set (thanks to Pedro Lopez-Cabonillas)
- v1.0.7: (7 December 2007)
- - configure and Makefile changes for MinGW
- - renamed midiinfo.cpp to midiprobe.cpp and updated VC++ project/workspace
- v1.0.6: (9 March 2006)
- - bug fix for timestamp problem in ALSA (thanks to Pedro Lopez-Cabanillas)
- v1.0.5: (18 November 2005)
- - added optional port name to openVirtualPort() functions
- - fixed UNICODE problem in Windows getting device names (thanks Eduardo Coutinho!).
- - fixed bug in Windows with respect to getting Sysex data (thanks Jean-Baptiste Berruchon!)
- v1.0.4: (14 October 2005)
- - added check for status byte == 0xF8 if ignoring timing messages
- - changed pthread attribute to SCHED_OTHER (from SCHED_RR) to avoid thread problem when realtime cababilities are not enabled.
- - now using ALSA sequencer time stamp information (thanks to Pedro Lopez-Cabanillas)
- - fixed memory leak in ALSA implementation
- - now concatenate segmented sysex messages in ALSA
- v1.0.3: (22 November 2004)
- - added common pure virtual functions to RtMidi abstract base class
- v1.0.2: (21 September 2004)
- - added warning messages to openVirtualPort() functions in Windows and Irix (where it can't be implemented)
- v1.0.1: (20 September 2004)
- - changed ALSA preprocessor definition to __LINUX_ALSASEQ__
- v1.0.0: (17 September 2004)
- - first release of new independent class with both input and output functionality
