Open Sound Control interface for Allen & Heath Xone:K2
======================================================
This small program implements OSC methods for an [A&H
Xone:K2](https://www.allen-heath.com/ahproducts/xonek2/) MIDI control surface.
The program is not intended to be a general solution for MIDI<-->OSC
communication. This implements things the way I use them. If you want
something else, I gleefully encourage you to fork and modify the code.
Installation
------------
You will need the development files for ALSA and liblo installed, as well as
[Meson](https://mesonbuild.com/). Then:
```
meson setup build
ninja -C build
```
Run with `build/x1k2-midi-osc` (no arguments) or install with `meson install build`.
Potentiometers
--------------
This program implements a soft pickup mechanism, using the LED of the button
below each potentiometer to indicate whether it is currently "congruent" or
not. Orange = not congruent, adjust the potentiometer until it matches the
pickup value. Green = congruent, turning the potentiometer will adjust the
value.
Numbering (`<n>`) is from top left (1) to bottom right (12). Top right is
number 4.
* `/x1k2/potentiometers/<n>/set-pickup <val>`
- Sets the pickup value to `<val>`.
* `/x1k2/potentiometers/<n>/enable`
- Activates the potentiometer.
* `/x1k2/potentiometers/<n>/disable`
- Activates the potentiometer.
When the potentiometer is *active* and *congruent* (picked up successfully),
the program will send the following message whenever the potentiometer is
moved:
* `/x1k2/potentiometers/<n>/value-change <val>`
Faders
------
The four faders work the same way as potentiometers, except that there's no
LED to indicate pickup. Numbering is from 1 to 4, left to right:
* `/x1k2/faders/<n>/set-pickup <val>`
* `/x1k2/faders/<n>/enable`
* `/x1k2/faders/<n>/disable`
* `/x1k2/faders/<n>/value-change <val>`
Buttons
--------
The following message will be sent when one of the buttons is pushed:
* `/x1k2/buttons/<name>/press`
The names (`<name>`) are exactly as labelled on the controller: `A` to `P`
(matrix of 16 buttons), `LAYER` and `SHIFT` (large buttons at the bottom, left
and right respectively).
The buttons under the potentiometers are handled elsewhere - see the section
about Potentiometers above.
You can set the colour of the LEDs under the buttons by sending:
* `/x1k2/buttons/<name>/set-led`
- `<colour>` = red,orange,green,off (string)
Rotary encoders
---------------
An `inc` or `dec` message will be sent when one of the four rotary encoders is
turned clockwise or counter-clockwise, respectively:
* `/x1k2/encoders/<n>/inc`
* `/x1k2/encoders/<n>/dec`
Numbering (`<n>`) is from left to right, 1 to 4, along the top row. 5 and 6
are the left and right encoders at the bottom of the panel, respectively.
If the encoder is pushed while turning, one of the following messages will be
sent:
* `/x1k2/encoders/<n>/inc-fine`
* `/x1k2/encoders/<n>/dec-fine`
You can set the colour of the LEDs under encoders 1-4 by sending:
* `/x1k2/encoders/<n>/set-led`
- `<colour>` = red,orange,green,off (string)
