This is a pure bug fix release compared to 1.1.4.

The following bugs are fixed:

  • Autotools build resulted in the wrong version number for libfluidsynth.so (reported by plcl, Takashi Iwai)
  • One symbol was dropped from libfluidsynth.so - this symbol was not part of the public API though. (reported by Alessio Treglia)
  • Windows 64 bit: Wrong prototype declaration for MIDI (reported by Graham Goode)
  • JACK: Using jack_free instead of free when needed. Note that this might require a later version of JACK than previously. (reported by Graham Goode)
  • Update Free Software Foundation address (reported by ogetbilo)

FluidSynth 1.1.4

In short

Version 1.1.4 brings:

  • Several improvements and fixes to the CMake build system, especially for Mac OS X
  • Several bug fixes to the engine, notably quite a few which could cause [FluidSynth] to sound bad in some cases.
  • API additions, that make it possible to
    • load MIDI files from memory
    • to inspect/modify MIDI events as they are being played from a MIDI file
    • to change channels between melodic and drum mode
    • and to silence all notes in one command.
  • Improvements to the CoreAudio driver
