# Information example

This example will show how to get some basic information sent to the UI.<br/>

The Plugin has a lot of parameter outputs which the UI uses to get info from.<br/>
This includes buffer-size and time position.<br/>
Sample-rate can be requested directly from the UI.<br/>
The UI will show this information as text.<br/>

The plugin will not do any audio processing.<br/>

# Meters example

This example will show how parameter outputs can be used for UI meters in DPF.<br/>
The plugin will inspect the host audio buffer but it won't change it in any way.<br/>

In this example the UI will display a simple meter based on the plugin's parameter outputs.<br/>
In order to make drawing easier the UI uses NanoVG instead of raw OpenGL.<br/>
Please see the Parameters and States examples before studying this one.<br/>

# Parameters example

This example will show how parameters work in DPF.<br/>
The plugin will not do any audio processing.<br/>

In this example the UI will display a 3x3 grid of colors which can be changed or automated by the host.<br/>
There are 2 colors: blue and orange. Blue means off, orange means on.<br/>
When a grid block is clicked its color will change and the host will receive a parameter change.<br/>
When the host changes a plugin parameter the UI will update accordingly.<br/>
