Matrix-Mixer
============

matrixmixer.lv2 is a matrix mixer :)

It is available as [LV2 plugin](http://lv2plug.in/) and standalone [JACK](http://jackaudio.org/)-application.
The jack application can run headless and be remote controlled via [OSC](http://opensoundcontrol.org/).

Install
-------

Compilation requires the LV2 SDK, jack-headers, gnu-make, a c-compiler,
libpango, libcairo, openGL (sometimes called: glu, glx, mesa), and
optionally libjack and liblo (for jack-app with remote-control)

```bash
git clone git://github.com/x42/matrixmixer.lv2
cd matrixmixer.lv2
make submodules
make
#sudo make install PREFIX=/usr
```

Note to packagers: The Makefile honors `PREFIX` and `DESTDIR` variables as well
as `CFLAGS`, `LDFLAGS` and `OPTIMIZATIONS` (additions to `CFLAGS`), also
see the first 10 lines of the Makefile.
You really want to package the superset of [x42-plugins](https://github.com/x42/x42-plugins).

The number of I/O can be set at compile time using `N_INPUTS` and `N_OUTPUTS` make variables.
The default is 8x8. Note that to change the size, a `make clean` is needed.

Usage
-----
* Click+drag or scroll-wheel on a knob to change gain
* Left-click a control to invert polarity (knob turns red)
* Middle-click on a knob to exclusively un/assigns it in the current row
* Right-click on a knob to toggle current/default value (by default matching I/O on the diagonal is set to 0dB)
