Qsampler A LinuxSampler Qt GUI Interface

What's Qsampler ?

Qsampler is a LinuxSampler GUI front-end application written in C++ around the Qt framework using Qt Designer. At the moment it just wraps as a client reference interface for the LinuxSampler Control Protocol (LSCP).

LinuxSampler is a work in progress. The goal is to produce a free, open source pure software audio sampler with professional grade features, comparable to both hardware and commercial Windows/Mac software samplers. The initial platform will be Linux because it is one of the most promising open source multimedia operating systems. Thanks to various kernel patches and the Jack Audio Connection Kit, Linux is currently able to deliver rock solid sub-5 millisecond MIDI-to-Audio response.

Requirements

The software requirements for build and runtime are listed as follows:

Mandatory:

• Qt framework (core, gui), C++ class library and tools for cross-platform application and UI development
  https://qt.io/
• liblscp, C library for LinuxSampler control protocol API.

Optional (opted-in at build time):

• libgig, C++ library for loading and modifying Gigasampler and DLS files.

Downloads

Latest release

2024-06-19 - An Unthinkable Release.
qsampler-1.0.0.tar.gz

• Making up the unthinkable (aka. v1.0.0)

Previous and older pre-releases, including the change log, are also available here. You may also check out from the latest bleeding edge development source tree, using Git.

You can browse all files available for download, including binary packages, at Qsampler Files on SourceForge.net.

Installation

You'll need to install the liblscp package before you can play with qsampler. This is for LinuxSampler Control Protocol support library, which qsampler is based.

Grab the source from here: liblscp-1.0.0.tar.gz

The installation procedure is quite similar for both packages, liblscp and qsampler. For each one, unpack the tarball and in the extracted source directory:

cmake [-DCMAKE_INSTALL_PREFIX=prefix] -B build

cmake --build build [--parallel Njobs]

and optionally as root:

[sudo] cmake --install build

Note that the default installation path prefix is /usr/local .

Configuration

Qsampler holds its settings and configuration state per user, in a file located as $HOME/.config/linuxsampler.org/Qsampler.conf. Normally, there's no need to edit this file, as it is recreated and rewritten everytime qsampler is run.

Bugs

Plenty still, however Qsampler may be considered in production/stable phase already.

Support

Qsampler is open source free software. For bug reports, feature requests, discussion forums, mailling lists, or any other matter related to the development of this piece of software, please use the LinuxSampler project site or the Sourceforge project page.
