As with many Linux applications DrumGizmo is available as a command line interface. This means that in addition to the gui versions of the software, you can also open up your favorite terminal and have the full potential of the virtual drummer at your fingertips by using the 'drumgizmo' command.

This is useful if you wish to use DrumGizmo in a stand-alone fashion, for instance to render a midi file to wav files. Or if you wish to make a jack connection and use DrumGizmo as a drum sampler in conjunction with an electronic drumkit.

$ drumgizmo [OPTIONS] drumkitfile

The 'drumgizmo' command currently accepts the following command line options. These options can also be found in the DrumGizmo man page:

       -a, --async-load
              Load drumkit in the background and start the engine immediately. 
              
       -i, --inputengine {dummy|test|jackmidi|midifile}
              Use said event input engine.

       -I, --inputparms parmlist
              Set input engine parameters.

              jackmidi:
              midimap=<midimapfile>

              midifile:
              file=<midifile>
              speed=<tempo> (default 1.0)
              track=<miditrack> (default -1, all tracks)
              midimap=<midimapfile>
              loop=<true|false>

              test:
              p=<hit_propability> (default 0.1)
              instr=<instrument> (default -1, random instrument)
              len=<seconds> (default -1, forever)

              dummy:

       -o, --outputengine {dummy|alsa|jackaudio|wavfile}
              Use said audio output engine.

       -O, --outputparms parmlist
              Set output engine parameters.

              alsa:
              dev=<device> (default 'default')
              frames=<frames> (default 32)
              srate=<samplerate> (default 44100)

              wavfile:
              file=<filename> (default 'output')
              srate=<samplerate> (default 44100)

              jackaudio:

              dummy:
              
       -r, --no-resampling    
              Disable resampling.
              
       -s, --streaming
              Enable diskstreaming

       -S, --strimingparms parmlist
              Parameters for controling the streaming buffers.
              limit=<size> (Limit preloaded drumkit data to the size)

       -e, --endpos
              Number of samples to process, (default -1: infinite)

       -v, --version
              Print drumgizmo version and exit.

       -h, --help
              Print command line help and exit.

       drumkitfile
              Load the drumkitfile.

$ drumgizmo  -i midifile -I file=file.mid,midimap=midimap.xml -o wavfile -O file=prefix drumkit.xml

This examples will render the midi file “file.mid” into a bunch of wav files called “prefix[channel name][#].wav”. Each wav then resembles the microphone that the drumkit was originally recorded with. You can import these into your favorite DAW (Digital Audio Workstation / sound editor) and mix it from there.

$ drumgizmo -i jackmidi -I midimap=~/DRSKit2_0_1/Midimap_full.xml -o jackaudio ~/DRSKit2_0_1/DRSKit_full.xml
