NAME
jalv.gtk3 - run an LV2 plugin with a GTK3 interface

SYNOPSIS
jalv.gtk3 [-dghmpstx] [-b, - -buffer-size=size] [-c, - -control=setting] [-l, - -load=dir] [-n, - -jack-name=name] [-P, - -preset=uri] [-r, - -update-frequency=hz] [-S, - -scale-factor=scale] [-U, - -ui-uri=uri] [plugin_state]

DESCRIPTION
jalv.gtk3 is a simple LV2 host that runs a single plugin. This version has a GTK3 interface that shows either generic controls or a custom plugin GUI.

jalv.gtk3 has one positional argument, which can be a plugin URI, preset URI, or the path to a bundle or data file that describes one. If none is given, then a plugin selector dialog is initially displayed.

The options are as follows:

-b, - -buffer-size=size
    Buffer size for plugin <=> UI communication.

-c, - -control=setting
    Set control value, for example, -c vol=1.4 where “vol” is the symbol of some control port on the plugin.

-d, - -dump
    Dump plugin <=> UI communication.

-g, - -generic-ui
    Show generic UI instead of custom plugin GUI.

-h, - -help
    Print the command line options.

-l frames
    Length of an audio block.

-m, - -minimal-ui
    Show only the plugin interface without any application extras.

-n, - -jack-name=name
    Use the given JACK client name. Note that JACK may adjust the name if necessary unless -x is also given.

-P, - -preset=uri
    Load the given preset before running plugin.

-p, - -print-controls
    Print control output changes to stdout.

-r, - -update-frequency=hz
    Set the UI update frequency. By default the screen refresh rate is used, typically 30 or 60 Hz.

-S, - -scale-factor=factor
    Override the UI scale factor.

-s, - -show-hidden
    Show controls that are normally hidden.

-t, - -trace
    Print debug trace messages. This enables the “trace” LV2 log, which is used by some plugins to print debugging output. Some extra internal error messages are also enabled. Note that this may print in the audio thread, which can cause dropouts.

-U, - -ui-uri=uri
    Load the UI with the given URI.

-x, - -exact-jack-name
    Use only the exact JACK client name given by -n or exit if it's unavailable.

ENVIRONMENT

LV2_PATH
    Search path for LV2 bundles, in PATH format.
