NAME
linuxsampler - modular, streaming capable sampler

SYNOPSIS
linuxsampler [OPTIONS]

DESCRIPTION
LinuxSampler is a modular, streaming capable sampler. Currently it supports the sampler formats Gigasampler/GigaStudio (.gig), SoundFont v2 (.sf2) and SFZ v2 (.sfz). The sampler is designed as backend, that is server-like console application. You will need a frontend application like QSampler or JSampler/Fantasia, which provide a graphical user interface (GUI) to control the sampler and manage sampler sessions conveniently. If you prefer, you can also control the sampler from the command line instead, for example by using the lscp(1) shell application shipped with LinuxSampler, which provides LSCP aware color highlighting, auto completion and more. Since the LSCP network interface is based on a human readable text protocol, you can also send LSCP commands by any other means to the sampler, e.g. by using telnet(1) or netcat(1). You can find examples and detailed informations about LinuxSampler's network protocol (LSCP) on http://linuxsampler.org/documentation.html#lscp_spec Various audio and MIDI driver systems are supported, like ALSA (audio & MIDI), JACK (audio & MIDI), ASIO, CoreAudio, CoreMIDI, Arts, MidiShare and MME. LinuxSampler can also be run as virtual instrument plugin. The following instrument plugin formats are currently supported: AudioUnit (AU), DSSI, LV2 and VST. You can also load effect plugins into the sampler. Currently only the LADSPA plugin format is supported for sampler internal effects. If you are using sounds in the Gigasampler/GigaStudio format, then you may also want to install the graphical instrument editor application called "gigedit", which can directly be launched by LinuxSampler, allowing to edit instruments in real-time (changes immediately being audible, without needing to reload the sound files in the sampler).

OPTIONS

--exec-after-init
    Executes the provided shell command(s) after initialization of application completed. You may use this to automatically restore a previous sampler session on startup, i.e. by sending a previously stored LSCP file via netcat(1). to the sampler.

--help
    Print command line help and exit.

--version
    Print version information and exit.

--profile
    This option is currently not supported anymore, since the respective profiling code is currently broken. Original behavior: Output benchmark messages on the console. This reflects the current efficiency as abstract BogoVoice count which is something like a theoretical limit of the amount of voices which can be rendered in the given scenario. It does not include all aspects of the sampler, that's why this value is usually higher than what you really can achieve on your box. Also note that this value is as well dependant on what instrument patch you are using and what you are playing. For a compact synthesis core benchmark, independent from drivers and instrument files, you might want to use the one coming with the sampler's source files instead (directory "benchmarks" of the source files).

--no-tune
    Disable assembly optimizations. Usually the sampler will detect CPU specific features like MMX and SSE at runtime and use an appropriate assembly optimized code in that case. With that switch you can disable this feature and force the sampler to skip the assembly optimizations at runtime.

--statistics
    Output voice and disk stream count periodically on the console.

--lscp-addr IPADDRESS
    Defines IP address on which the LSCP server should listen to (default: any).

--lscp-port NUMBER
    Defines TCP port on which the LSCP server should listen to (default: 8888).

--create-instruments-db [FILE]
    Creates a database file with the given filename which can be used by the sampler's instruments database system to maintain the user's collection of instrument libraries. When this argument is given, the sampler will just create the instruments DB file and exit. If the optional file argument is omitted, then a default location for the instrument DB file is used instead.

--instruments-db-location FILE
    Overrides the location of the database file, which the sampler shall use for its instruments database system (default: /var/lib/linuxsampler/instruments.db).

ENVIRONMENT VARIABLES

LINUXSAMPLER_PLUGIN_DIR
    Allows to override the directory where LinuxSampler shall look for instrument editor plugins.

LADSPA_PATH
    Allows to override the directory where LinuxSampler shall look for LADSPA effect plugins. Multiple paths may be given, separated by colon (":") character on POSIX systems (i.e. Linux and Mac), or separated by semi-colon (";") character on Windows systems.
