NAME
       bsescm -	A Guile	based scheme shell for Beast and Bse.

SYNOPSIS
       bsescm [options]	[--] ...

       bsescm [options]	_infile.bse_ ...

DESCRIPTION
       bsescm is a Guile based scheme shell for	Bse, the Better	Sound Engine.

       bsescm provides a shell interface to all	procedures exported by the Bse
       library,	so scripts are able to access the full range of	 functionality
       provided	by it, from simple playback of a .bse file to full fledged au-
       tomated creation	or editing of synthesis	networks.

       Alternatively to	the linked in Bse library, the bsescm language	inter-
       face can	also talk to a remotely	running	Bse library host, for instance
       Beast.  By operating on a remotely running Bse core, bsescm can be used
       to  script  arbitrary  Bse programs. The	shell is also used directly by
       the Bse library to execute procedures on	its behalf,  this  allows  Bse
       procedures to be	written	in scheme.

       When  started,  bsescm tests whether the	first non-option argument is a
       .bse file and if	the test succeeds, attempts to play the	 command  line
       arguments as .bse files.

OPTIONS
       bsescm  follows	the  usual  GNU	command	line syntax, with long options
       starting	with two dashes	('--').

       --bse-pipe infd outfd
	      Provide the input	and output communication  filedescriptors  for
	      remote operation.

       --bse-eval string
	      Execute  (eval-string  string) instead of	going into interactive
	      mode.

       --bse-enable-register
	      Allowes registration of procedures with the Bse core.

       --bse-no-load
	      Prevent automated	loading	of plugins and scripts at startup time
	      in interactive mode.

       --bse-no-play
	      Prevent  automated  detection  and playback of .bse file command
	      line arguments.

       --g-fatal-warnings
	      Make runtime warnings fatal (abort).

       -h, --help
	      Describe command line options and	exit.

       -v, --version
	      Display version and exit.

       -n=nicelevel
	      Execute with priority nicelevel, this option only	 takes	effect
	      for the root suid	wrapper	'beast'.

       -N     Disables renicing	to execute with	existing priority.

       --bse-latency=useconds
	      Set the allowed synthesis	latency	for Bse	in milliseconds.

       --bse-mixing-freq=frequency
	      Set the desired synthesis	mixing frequency in Hz.

       --bse-control-freq=frequency
	      Set  the	desired	 control  frequency in Hz, this	should be much
	      smaller than the synthesis mixing	frequency to reduce CPU	 load.
	      The  default  value  of  approximately 1000 Hz is	usually	a good
	      choice.

       --bse-pcm-driver	driver-conf

       -p driver-conf
	      This options results in  an  attempt  to	open  the  PCM	driver
	      driver-conf  when	 playback  is started. Multiple	options	may be
	      supplied to try a	variety	of drivers and unless  driver-conf  is
	      specified	 as  "auto",  only  the	 drivers listed	by options are
	      used. Each driver-conf consists of a driver name and an optional
	      comma  seperated list of arguments attached to the driver	withan
	      equal sign, e.g.:	-p oss=/dev/dsp2,rw -p auto

       --bse-midi-driver driver-conf

       -m driver-conf
	      This option is similar to	the --bse-pcm-driver option,  but  ap-
	      plies to MIDI drivers and	devices. It also may be	specified mul-
	      tiple times and features an "auto" driver.

       --bse-driver-list
	      Produce a	list of	all available PCM and MIDI drivers and	avail-
	      able devices.

   Guile Options:
       -l file
	      Load scheme source code from file.

       -e function
	      After reading script, apply function to command-line arguments.

       -ds    Do -s script at this point (note that this argument must be used
	      in conjuction with -s).

       --debug
	      Start with debugging evaluator and  backtraces  enabled  (useful
	      for debugging scripts).

       --emacs
	      Enable emacs protocol for	use from within	emacs (experimental).

       The  remaining Guile options stop argument processing, and pass all re-
       maining arguments as the	value of (command-line):

       --     Stop argument processing,	start in interactive mode.

       -c expr
	      Stop argument processing,	evaluate expr as a scheme expression.

       -s script
	      Load Scheme source from script and execute as a script.
