The Patcher system can be used for DSP audio, but also for controlling routes in a visual manner. If you have worked with Max/MSP or Pure Data before, you will feel right at home.
To add blocks to a patcher, you should enable edit mode. The can be done with the switch on top of the screen, or by pressing
CTRL+E. The same shortcut can be used to leave edit mode.
In edit mode, you can add and remove blocks at will. Adding blocks can be done with the shortcut
CTRL+A. Remove them by selecting a block (or a connection) and pressing
Connections between blocks can be made by clicking on a block outlet (the dot at the bottom) and dragging it to the inlet of another block. In most cases, the leftmost inlet is active. This means that when a message arrives at this inlet, it will trigger calculations and output a value at the outlet.
DSP blocks are audio blocks and will output values continuously. All blocks starting with a
~ are DSP blocks. Blocks starting with a dot are normal data blocks.
The Interact sound engine and its patcher system are independent projects. A list of available blocks can be found in the documentation section of the YAP website.
Unique to Interact are the routing blocks. You can receive data from other parts of Interact by using a
.r name block. The name should be a meaningful value, indicating what this route is for. This is all you need to setup a route endpoint to your patch. Once done, you can open the router on a gui element end select this endpoint. You can also use this route from a script.
Sending data to another route can be done with the
.s /name/of/route block. If you need to know the name of route to a gui element, you can right click on the element (when not in edit mode) and select the desired route to copy it to memory.
