.SH NAME

FluidSynth \- a SoundFont synthesizer
|
|
.SH SYNOPSIS
|
|
.B fluidsynth
|
|
.RI [ options ]
|
|
[ SoundFonts ]
|
|
[ midifiles ]
|
|
.SH DESCRIPTION
|
|
\fBFluidSynth\fP is a real-time MIDI synthesizer based on the
|
|
SoundFont(R) 2 specifications. It can be used to render MIDI input or
|
|
MIDI files to audio. The MIDI events are read from a MIDI device. The
|
|
sound is rendered in real-time to the sound output device.
|
|
.PP
|
|
The easiest way to start the synthesizer is to give it a SoundFont on
|
|
the command line: 'fluidsynth soundfont.sf2'. fluidsynth will load the
|
|
SoundFont and read MIDI events from the default MIDI device using the
|
|
default MIDI driver. Once FluidSynth is running, it reads commands
|
|
from the stdin. There are commands to send MIDI events manually, to
|
|
load or unload SoundFonts, and so forth. All the available commands are
|
|
discussed below.
|
|
.PP
|
|
FluidSynth can also be used to play a list of MIDI files. Simply run
|
|
FluidSynth with the SoundFont and the list of MIDI files to play. In
|
|
this case you might not want to open the MIDI device to read external
|
|
events. Use the \-n option to deactivate MIDI input. If you also
|
|
want to deactivate the use of the shell, start FluidSynth with the \-i
|
|
option: 'fluidsynth \-ni soundfont.sf2 midifile1.mid midifile2.mid'.
|
|
.PP
|
|
Run fluidsynth with the \-\-help option to check for changes in the list of options.
