# jalv.qt5(1)

run an LV2 plugin with a Qt5 interface

## NAME

**jalv.qt5** – run an LV2 plugin with a Qt5 interface

## SYNOPSIS

**jalv.qt5** *plugin\_state*

## DESCRIPTION

**jalv.qt5** is a simple LV2 host that runs a single plugin. This version has a Qt5 interface that shows either generic controls or a custom plugin GUI.

**jalv.qt5** has one positional argument, which can be a plugin URI, preset URI, or the path to a bundle or data file that describes one.

This version is mainly for testing and has no options or plugin selector. For a more complete graphical version, see [jalv.gtk3(1)](/jalv.gtk3/1.md).
