NAME
       jack-dssi-host - a simple JACK host for DSSI plugins

SYNOPSIS
       jack-dssi-host [-v] [-a] [-n] [-p <projdir>] [-c <cname>] [-<i>]
       <libname>[:<label>] [...]

DESCRIPTION
       jack-dssi-host is a simple DSSI host that listens for MIDI events on an
       ALSA sequencer port, delivers them to DSSI synth plugins, and outputs
       the resulting audio via JACK.
       jack-dssi-host can host up to 16 instances of DSSI synth plugins, each
       of which is sequentially assigned a MIDI channel from 1 to 16.  Plugin
       outputs (if `-a' is not specified) are connected sequentially to the
       available JACK physical output ports, wrapping back to the first JACK
       port whenever the available ports are exhausted.  Plugin user
       interfaces (UIs) are started for each instance (if '-n' is not
       specified.)  jack-dssi-host will exit when the last plugin UI has
       exited.
       As a special case, if jack-dssi-host is started with a name other than
       `jack-dssi-host', and if that name (plus an `.so' suffix) can be found
       in the DSSI_PATH search path (see ENVIRONMENT below) as a valid plugin
       shared library, and if no further command line arguments are given,
       then the first plugin in that library will be loaded automatically.
       This provides a convenient way to run a plugin by simply symlinking the
       plugin's basename to jack-dssi-host.

OPTIONS
       -v     Verbose mode.

       -a     Disable automatic connection of outputs to JACK physical
              outputs.

       -n     Disable automatic starting of plugin user interfaces (UIs).

       -p <projdir>
              The project directory to pass to both plugin and UI.

       -c <cname>
              The client name to use for ALSA and JACK.

       -<i>   Number of instances of the following plugin to run (max 16
              total, default 1).

       <libname>
              Name of the DSSI plugin shared library (.so) to load. This may
              be an absolute path to the library file, or just the filename
              itself, in which case the DSSI search path is searched (see
              ENVIRONMENT below).

       <label>
              the label of the plugin to load from the library.  If this is
              omitted, the first plugin in the library is used.

       [...]  Optionally more instance counts, plugins and labels.

EXAMPLE
       jack-dssi-host -2 lib1.so -1 lib2.so:fuzzy
       Runs two instances of the first plugin found in lib1.so, assigned to
       MIDI channels 1 and 2 and connected to the first available JACK
       outputs, and one instance of the "fuzzy" plugin in lib2.so on MIDI
       channel 3 and connected to the next available JACK output.

ENVIRONMENT
       jack-dssi-host will search for plugin shared libraries in the
       directories specified by the environment variable DSSI_PATH, which is a
       colon-separated list of directories. If DSSI_PATH is not set, a default
       search path of /usr/lib/dssi, /usr/local/lib/dssi, and (assuming the
       environment variable HOME is set,) $HOME/.dssi is used.
