NAME
       TiMidity	- MIDI to WAVE converter and player

SYNOPSIS
       timidity	[-options] filename [filenames ...]

DESCRIPTION
       TiMidity	is a MIDI to WAVE converter using Gravis Ultrasound-compatible
       patch files to generate digital audio data  from	 General  MIDI	files.
       The data	can be stored in a file	for processing,	or played in real time
       through an audio	device.

OPTIONS
       The following command line options are  accepted	 by  version  0.2i  of
       TiMidity:

       -o filename
	      Place  output on filename, which may be a	file, device, or HP-UX
	      audio server, depending on the output mode selected with the  -O
	      option. The special filename ``-'' causes	output to be placed on
	      stdout.

       -O mode
	      Selects the output mode from the compiled-in alternatives.  mode
	      must  begin  with	 one of	the supported output mode identifiers.
	      Run TiMidity with	the -h option to see a	list.	The  following
	      identifiers should be available in all versions:

	      -Or    Generate  raw waveform data.  All format options are sup-
		     ported.  Common formats include:

		     -OrU   uLaw

		     -Or1sl 16-bit signed linear PCM

		     -Or8ul 8-bit unsigned linear PCM

	      -Ow    Generate RIFF WAVE	format output.	If output is  directed
		     to	a non-seekable file, or	if TiMidity is interrupted be-
		     fore closing the  file,  the  file	 header	 will  contain
		     0xFFFFFFFF	in the RIFF and	data block length fields.  The
		     popular sound conversion utility sox is able to read such
		     malformed files, so you can pipe data directly to sox for
		     on-the-fly	conversion to other formats.

	      Format options
		     Option characters may be added immediately	after the mode
		     identifier	 to  change  the output	format.	 The following
		     options are recognized:

		     8	    8-bit sample width

		     1	    16-bit sample width

		     l	    Linear encoding

		     U	    uLaw (8-bit) encoding

		     M	    Monophonic

		     S	    Stereo

		     s	    Signed output

		     u	    Unsigned output

		     x	    Byte-swapped output

	      Note that	some options have no effect on some modes.  For	 exam-
	      ple, you cannot generate a byte-swapped RIFF WAVE	file, or force
	      uLaw output on a Linux PCM device.

       -s frequency
	      Sets the resampling frequency.  Not all sound devices are	 capa-
	      ble  of  all  frequencies	-- an approximate frequency may	be se-
	      lected, depending	on the implementation.

       -a     Turns on antialiasing. Samples are run through a lowpass	filter
	      before  playing,	which reduces aliasing noise at	low resampling
	      frequencies.

       -f     Toggles fast envelopes. Some MIDI	files sound better when	 notes
	      decay  slower -- it gives	the impression of reverb, which	TiMid-
	      ity doesn't currently support.

       -e     Make TiMidity evil.  On Win32 version, this increases  the  task
	      priority	by  one.  It  can give better playback when you	switch
	      tasks at the expense of slowing all other	tasks down.

       -p voices
	      Sets  polyphony  (maximum	 number	 of  simultaneous  voices)  to
	      voices.

       -A amplification
	      Multiplies the master volume by amplification%.

       -C ratio
	      Sets the ratio of	sampling and control frequencies.  This	deter-
	      mines how	often envelopes	are recalculated -- small ratios yield
	      better quality but use more CPU time.

       -L directory
	      Adds  directory  to the library path.  Patch, configuration, and
	      MIDI files are searched along this path.	Directories added last
	      will  be searched	first.	Note that the current directory	is al-
	      ways searched first before the library path.

       -c file
	      Reads an extra configuration file.

       -I number
	      Uses the program number as the default instrument.  Any  Program
	      Change events in MIDI files will override	this option.

       -P file
	      Uses  the	 patch	file  for every	program	except drums.  Program
	      Change events will be ignored.  This is useful for  testing  new
	      patches.

       -D channel
	      Marks  channel as	a drum channel.	 If channel is negative, chan-
	      nel -channel is marked as	an instrumental	channel.   If  channel
	      is 0, all	channels are marked as instrumental.

       -Q channel
	      Causes  channel  to  be  quiet.  If channel is negative, channel
	      -channel is turned back on.  If channel is 0, all	 channels  are
	      turned on.

       -F     Turns  on	 fast  panning	to accommodate MIDI pieces that	expect
	      panning adjustments to affect notes that	are  already  playing.
	      Some  files that don't expect this have a	habit of flipping bal-
	      ance rapidly between left	and right, which can cause severe pop-
	      ping when	the -F flag is used.

       -U     Instructs	TiMidity to unload all instruments from	memory between
	      MIDI files.  This	can reduce memory  requirements	 when  playing
	      many files in succession.

       -i interface
	      Selects  the  user  interface from the compiled-in alternatives.
	      interface	must begin with	one of the supported interface identi-
	      fiers.  Run TiMidity with	the -h option to see a list.  The fol-
	      lowing identifiers may be	available:

	      -id    The dumb interface	-- plays  files	 in  sequence,	prints
		     messages  according  to  verbosity	level.	The trace mode
		     shows the current and total playing time.

	      -im    The motif interface -- X Window interactive interface.

	      -ik    The Tcl/Tk	interface -- X Window interactive interface.

	      -in    The ncurses full-screen interface with  interactive  con-
		     trols.

	      -is    The  S-Lang  full-screen  interface with interactive con-
		     trols.

	      Interface	options
		     Option characters may be added immediately	after the  in-
		     terface  identifier.   The	 following  options are	recog-
		     nized:

		     v	    Increases verbosity.  This option is cumulative.

		     q	    Decreases verbosity.  This option is cumulative.

		     t	    Toggles trace mode.	 In trace mode,	 TiMidity  at-
			    tempts  to display its current state in real time.
			    For	the Linux sound	driver,	this  is  accomplished
			    through  the  use  of  short DMA buffer fragments,
			    which can be tuned via the -B option.

       -B fragments
	      For the Linux sound driver, selects the number of	 buffer	 frag-
	      ments  in	 interactive mode.  Increasing the number of fragments
	      may reduce choppiness when many processes	are running.  It  will
	      make  TiMidity  seem  to	respond	 sluggishly  to	 fast forward,
	      rewind, and volume controls, and it will throw the  status  dis-
	      play off sync.  Specify a	fragments of 0 to use the maximum num-
	      ber of fragments available.

FILES
       TiMidity	looks for the configuration file timidity.cfg at startup,  be-
       fore  processing	any options.  If it can't be accessed, and the library
       path is changed with a -L option	on the command line, then the  default
       file  will  be sought again along the new library path after processing
       all options, unless another configuration file was specified  with  the
       -c option.

       Configuration  files  define the	mapping	of MIDI	programs to instrument
       files.  Multiple	files may be specified,	and statements in  later  ones
       will  override earlier ones.  The following statements can be used in a
       configuration file:

       dir directory
	      Adds directory to	the search path	in the same manner as  the  -L
	      command line option.

       source file
	      Reads  another configuration file, then continues	processing the
	      current one.

       bank number
	      Selects the tone bank to modify.	 Patch	mappings  that	follow
	      will affect this tone bank.

       drumset number
	      Selects the drum set to modify.  Patch mappings that follow will
	      affect this drum set.

       number file [options]
	      Specifies	that the the MIDI program number in the	 current  tone
	      bank or drum set should be played	using the patch	file.  options
	      may be any of the	following:

	      amp=amplification
		     Amplifies the instrument's	volume by  amplification  per-
		     cent.   If	 no  value is specified, one will be automati-
		     cally determined whenever the instrument is loaded.

	      note=note
		     Specifies a fixed MIDI note to use	when playing  the  in-
		     strument.	If note	is 0, the instrument will be played at
		     whatever note the Note On event triggering	 it  has.  For
		     percussion	 instruments,  if no value is specified	in the
		     configuration file, the default in	the patch file will be
		     used.

	      pan=panning
		     Sets  the	instrument's  default panning.	panning	may be
		     left, right, center, or an	integer	between	-100 and  100,
		     designating full left and full right respectively.	 If no
		     value is specified, the default in	the patch file will be
		     used.   Note  that	 panning  controls  in MIDI files will
		     override this value.

	      keep={loop|env}
		     By	default, percussion instruments	have  their  loop  and
		     envelope information stripped. Strangely shaped envelopes
		     are removed automatically	from  melodic  instruments  as
		     well.  keep  can be used to prevent stripping envelope or
		     loop data.	For example, the Short and Long	 Whistle  per-
		     cussion instruments (General Midi numbers 71 and 72) need
		     to	have ``keep=loop keep=env'' specified in the  configu-
		     ration file.

	      strip={loop|env|tail}
		     Force  removal  of	 loop or envelope information from all
		     patches in	the instrument,	or strip the  tail,  i.e.  all
		     data  after  the  loop. Some third-party instruments have
		     garbage after the loop, as	evidenced by a clicking	 noise
		     whenever	the   instrument  is  played,  so  adding  the
		     strip=tail	option will markedly improve sound quality.

       NOTE: Whenever any filename ends	in one of the compiled-in  compression
       identifiers,  such as .gz, or .sht, TiMidity will pipe the file through
       the appropriate decompressor.  MIDI files often compress	very well,  so
       the ability to handle compressed	files can be useful.

       The  special filename ``-'' can be used on the command line to indicate
       that a MIDI file	should be read from stdin.
