New release 2.2.2

Hi all,

a new version of llcon client/server software was just released. The version number is 2.2.2.

This version adds some useful features to the software like storing the server URLs or adding a mute and solo switch to each audio fader.

The main GUI layout was changed to make it easier to use. Also, a new LED look was introduced.

New release 2.2.0

Hi all,

a new version of llcon client/server software was just released. The version number is 2.2.0.

In this release a Jack audio interface is available under the Linux OS.

The overall audio stability is improved by using the same buffer size for network and audio in the client. This also simplifies the settings since the intermediate buffers are removed and must not be configured.
