MIDI CONTROLLER
=========================
This is a simple MIDI controller with dynamic GUI for programs 
that use the ALSA sequencer library. It's free software under the
terms of the GNU General Public License, see the file COPYING for
details.


Installation
=========================
You need to have the ALSA libraries and headers installed, as
well as the headers and libraries for libglademm, libgtkmm,
and all their dependencies. You also need pkg-config and the
pkg-config files for ALSA and libglademm.

To install, do this:

* set the variable PREFIX in the Makefile to the directory where
  you want to install MIDI Controller (the default is /usr/local)

* type 'make'

* become root (unless you have write access to the PREFIX 
  directory) and type 'make install'

If you get any errors along the way that you don't know how to
fix, send me an email at larsl@users.sourceforge.net.


GUI
=========================
This program uses libglademm to create its GUI. This means that
the GUI is defined in an XML file which is loaded by the program
at runtime. The program will look for Scrollbar, Scale, or Spinbutton
widgets with the names "mcwC4P0", "mcwC1P3" and so on. A widget
with the name "mcwC1P5" will send control change values for CC number
5 on channel 1. If you use 'c1' or 'p2' instead of 'C1' or 'P2', the
program will look for another widget with the name 'mcwC1' or 'mcwP2',
and the value of this widget will be used to set the channel or CC number
for the original widget.

Example 1:
One VScale widget named "mcwc1P1", one SpinButton named "mcwC1".
The VScale will control CC number 1 on channel B, where B is the
current value of the SpinButton.

Example 2:
Once VScale widget named "mcwC3p3", one SpinButton named "mcwP3".
The VScale will control CC number D on channel 3, where D is the 
current value of the SpinButton.

This means that you can build your own GUI in Glade with
arbitrarily many controllers, with the layout that you want, as
long as you name your widgets according to the pattern described
above. For example, you could build a GUI that is customized for
your new cool AMS patch with exactly the MIDI controllers it uses
together with explaining text and a nice picture, or a GUI that
acts as a single control interface for your jack network of
20 different softsynths, samplers, and effects.


Usage
===========================
When you run the program you can specify the GUI file you want to
use as a command line parameter, like this:

[ll@gnorf ll]$ midicontroller mynewgui.glade

Or you can just run the program without any parameters, in which
case it will first try to load the GUI file controller.glade in
the current direcory, and if that fails, the file with the same
name in the system data directory (which is 
/usr/local/midicontroller/controller.glade, unless you have changed 
the PREFIX variable in the Makefile). Once the program is started
and the GUI is loaded you can connect its MIDI output port to one
or more MIDI output ports using aconnect, qjackctl, or some other
tool.

If you press the key F1 when you are using the program you will see a
popup menu where you can

 * save and load presets. A preset is a file that stores the current
   value of every control widget.
 * send the current value of all CC's to the MIDI out port. This can
   be useful if you restart a synth program or change its control
   parameters in some other way, and want to restore them. This is done
   automatically when you load a preset.
 * view a simple "About" window for this program
