This is a series of tutorials that look at small pieces of the factory setups, and how to achieve the same functionality in your own setups.
In general, the factory setups are a good place to start looking to see how something is done. Load up a factory setup for your instrument and use the edit tool to look at the properties of the agents. Of particular interest are the talker agents. Their properties hold the belcanto strings that are used to control much of the functionality in eigenD, and they are not visible in the same way as the wires in workbench.
The tutorials below are best read after going through the introductory tutorials and Building_Your_First_Setup_From_Scratch
