What's QmidiNet ?

QmidiNet is a MIDI network gateway application that sends and receives MIDI data (ALSA Sequencer and/or JACK MIDI) over the network, using UDP/IP multicast. Inspired by multimidicast (http://llg.cubic.org/tools) and designed to be compatible with ipMIDI for Windows (http://nerds.de).

QmidiNet is free, open-source software, distributed under the terms of the GNU General Public License (GPL) version 2 or later.

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


Optional (opted-in at build time):


Latest release

2018-05-21 - Pre-LAC2018 release frenzy.

Previous and older 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 QmidiNet Files on SourceForge.net.


The installation procedure follows the standard for source distributions. In the extracted source directory, just do:

./configure [--prefix=prefix]


and optionally as root:

[sudo] make install

This procedure will end installing the following couple of files:

Just launch prefix/bin/qmidinet and you're off (hopefully). Note that the default installation path prefix is /usr/local.


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


Plenty still, after all this is alpha software ;)


QmidiNet 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 Sourceforge project page.
