.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, andsoforth. 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.

.TP
.B MIDI ROUTER
.TP
.B router_default
Reloads the default MIDI routing rules (input channels are mapped 1:1
to the synth)
.TP
.B router_clear

Starts a new routing rule for events of the given type
.TP
.B router_chan min max mul add
Limits the rule for events on min <= chan <= max.
If the channel falls into the window, it is multiplied by 'mul', then
'add' is added.
.TP
.B router_par1 min max mul add
Limits parameter 1 (for example note number in a note events). Similar
to router_chan.
.TP
.B router_par2 min max mul add

.TP
router_begin note
.TP

.TP
router_end
.TP
Will accept only note events from the lower 8 MIDI
channels. Regardless of the channel, the synthesizer plays the note on
ch 15 (synthchannel=midichannel*0+15)
