==============================

**jack_mixer** is a GTK+ JACK audio mixer app with a look & handling similar to
hardware mixing desks. It has lot of useful features, apart from being able to
mix multiple JACK audio streams.

It is licensed under GPL version 2 (or later), check the file [COPYING] for
more information.

## Installation

To build and install jack_mixer run:

```console
meson builddir --prefix=/usr --buildtype=release
meson compile -C builddir
[sudo] meson install -C builddir
```

Please read the file [INSTALL.md] for more information and requirements.


## Using MIDI CCs to control jack_mixer

MIDI Control Change messages (CCs) can be used to control volume,
balance/panorama, mute, and solo of input and output channels.

The default controllers for added channels are chosen using a predefined
algorithm: the first free controller starting from #11, first for volume, next
for balance/panorama, then mute and finally solo.

So, if you don't delete channels, CC#11 will control the first channel's
volume, CC#12 the balance/panorama, CC#13 the mute and CC#14 the solo switch.
CC#15 will control the second channel' volume, CC#16 it's balance/panorama, and
so on.

It is also possible to set other CCs when creating a channel, or afterwards
from the channel properties dialog (accessible from the menu or by double
clicking on the channel name).

MIDI CC values (0-127) are mapped to dBFS using the current slider scale for
the corresponding channel.
