The name fluidity would be a great variant on timidity (which in turn is a magnificent variant of audacity), but 'fluidity' is already a one-person Nintendo video game, released 6dec2010.
So the name fluadity was chosen, since it also contains Lua which is the language it uses, and has no previous meaning, is easy to pronounce, and is highly searchable.
It is intended to have a much lower latency than timidity, so as to be good for real-time work. Its command-line is leaner and easier to remember than timidity's (which is however already pretty good). But it can only use SoundFonts, and so is less configurable.
It has similar functionality to the fluidsynth command, but is even easier to use, can run as a daemon, and features a convenient default configuration file ~/.fluidsynth or /etc/fluidsynth.conf
Since version 2.0 fluadity offers the cc126 controller which sets Monophonic mode, and the cc127 controller which restores Polyphonic mode. This behaviour is not very conformant to the rarely-used MIDI-standard behaviour :-( but it is useful, and respects at least the names of these controllers.
It uses the midialsa and fluidsynth Lua modules, which in turn need the alsa and fluidsynth C-libraries and associated header-files. Because it uses the midialsa library, it feels most at home on Linux. In -d daemon-mode, it also needs the luaposix module.
Invokes Compatibility-mode. By default, the fluidsynth library:
Starts a daemon running an ALSA-midi client
called Fluadity (note: upper-case F).
This can be invoked, for example, in
In daemon mode the default configuration file is
Users can then set
Reads the configuration from the given file.
The default configuration file is
or if that does not exist then
These are also the default config files for the fluidsynth executable.
This module only recognises set, load and select commands;
see man fluidsynth
In this example, the select command chooses for channel 9, from soundfont 1 (Chaos4m.sf2) the bank 127 patch 99, which happens to be a percussion set, as you typically want on channel 9.
This is the format:
set audio.driver alsa set synth.polyphony 1024 load /home/soundfonts/Chaos4m.sf2 load /home/soundfonts/MyGM.sf2 load /home/soundfonts/ReallyGoodPiano.sf2 select 9 1 127 99
Starts an ALSA-midi client called fluadity
which it connects from (in this example) the
ProKeys and Keystation midi-keyboards.
In this mode, fluadity terminates when all its inputs disconnect.
Of course it terminates also if killed or interrupted (eg: with ctrl-C twice), but in this case it leaves a temporary file undeleted in /tmp containing all the library's stderr output.
This loads a soundfont from the command-line,
and ignores all the soundfonts in the config file.
Multiple -s options may be given.
Prints the Version
20160224 2.0 in daemon mode: interprets cc126 as Monophonic, 127 as Polyphonic 20150413 1.9 handles notes-off and sounds-off events and disconnects correctly 20150206 1.8 in deamon mode: sosped, maxnotes=20, and nested note_ons 20140904 1.7 if -s is given, use the fluidsynth.lua 1.7 syntax 20140903 1.6 if -s is given, still read the non-'load' config lines 20140903 1.5 as daemon, sighandler now works also before a synth starts 20140901 1.4 as daemon, only run a synth while there are connections 20140831 1.3 add -d daemon option 20140829 1.2 remove the TmpFile stuff, now fluidsynth understands '-' 20140825 1.1 first working version
Fluadity is available at:
Just move it into your PATH, make it executable, and if necessary edit the first line to match where Lua is installed on your system.
You will also need the fluidsynth, midialsa and luaposix modules:
luarocks install fluidsynth luarocks install midialsa luarocks install luaposix
