This example will show how states work in DPF.
The plugin will not do any audio processing.
In this example the UI will display a 3x3 grid of colors which can not be changed by the host.
There are 2 colors: blue and orange. Blue means off, orange means on.
When a grid block is clicked its color will change and the host will receive a message which is auto-saved.
When the UI is opened it will receive messages indicating the last used block states.
