Okay, this tutorial will explain some of the (VST)
plugin-specific aspects of the Pedal Board.

________
A VST plugin appears as a rectangle in the main window,
with 3 buttons on it:
<img=docs/images/plugin1.png>
It was designed to look like a guitar stomp box (in an
abstract-kinda-way), with a bypass button at the bottom,
and the important controls at the top.  The signal path of
the program is always left(input) -> right(output).  To
remove a plugin, simply right-click on it, and select
'Delete this Plugin'.

- Bypass basically removes the plugin from the audio signal
  path.
- Edit opens the plugin's editor, like so:

- Mappings opens up a dialog allowing you to set up
  mappings between a joystick, envelope detector, or MIDI
  input source, and the plugin's parameters.  Both the
  Parameter and MIDI tutorials go into more detail on this
  aspect of the program.

________
You'll notice that on the plugin's editor window, there are
two controls at the top of the window.  The combo box lets
you select a program/preset in the plugin to use, while the
'Mix' slider lets you set how much of the input signal is
mixed back into the output (100% = no input, full output;
0% = full input, no output).

________
Some VST plugins rely on the host to provide timing
information.  While the pedal board does not support the
more complex VstTimeInfo structure, it does provide
plugins with information about the current tempo.  To
set the bpm that the pedal board reports to plugins,
select the 'VST Options' item in the Options menu:
<img=docs/images/plugin3.png>
This will open a dialog where you can set the tempo.
