       bsescm - A Guile based scheme shell for BEAST and BSE.


       bsescm [OPTIONS] [--] ...
       bsescm [OPTIONS] infile.bse ...


       bsescm  is  a  Guile  based  scheme shell for BSE, the Bedevilled Sound

       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
       automated creation or editing of synthesis networks.

       Alternatively  to  the  linked  in  BSE  library,  the  bsescm language
       interface can also talk to a remotely running  BSE  library  host,  for
       instance beast(1).  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.


       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

              Allowes registration of procedures with the BSE core.

              Prevent automated loading of plugins and scripts at startup time
              in interactive mode.

              Prevent automated detection and playback of  .bse  file  command
              line arguments.

              Make runtime warnings fatal (abort).

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

       -v, --version
              Display version and exit.

              Execute  with  priority NICELEVEL, this option only takes effect
              for the root suid wrapper ’beast’.

              Disables renicing to execute with existing priority.

              Set the allowed synthesis latency for BSE in milliseconds.

              Set the desired synthesis mixing frequency in Hz.

              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

       --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
              applies to MIDI drivers and devices. It also  may  be  specified
              multiple times and features an ‘auto’ driver.

              Produce  a  list  of  all  available  PCM  and  MIDI drivers and
              available devices.

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

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

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

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

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

       The remaining Guile options stop  argument  processing,  and  pass  all
       remaining 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.
