To "connect" the forward method to the OSCemote button, add an OSC Input Node to the scene. Try clicking on the plus next to the Counter's Forward Input Property to verify that the switcher is working correctly. Bind the Switch's Case Property to the Value output property of the Counter. To iterate through the different cases, add a Counter Node, set its End Input Property to the number of the last Switch Output and activate the Loop Property. This will be the Ventuz functionality we want to remote control. Set each Scene Port to a different scene you want to show. Add a Layer Switch and add a Scene Layer to each output of the Switch. Often using a high port number such as 19500 will decrease the chances of a potential conflict, though not eliminate them completely. Also make sure that the port is not blocked by any firewall. Set the port to some number that is currently not used (don't use 3333 as that is usually used by TUIO). In OSCemote, go to More/Settings and enter that IP-address. Start the CMD program on the Ventuz machine and type ipconfig to get the current IP-address of that machine in the network. We'll add an OSC Input Node to our scene so that a Ventuz event is fired whenever that button is pressed.įirst, make sure that both the Ventuz machine and the iOS device are connected to the same wireless network. As can be found in the developer documentation, the first button sends the following OSC message if it is pressed: OSCemote is split into multiple views of which we will use the 5x3 grid of buttons. This How To will use OSCemote to show you how to trigger events in Ventuz but based on the specific requirements, a different App such as TouchOSC or ControlOSC, or any other, might be more suitable for you. We are not specifically recommending it, but it will do as a good example. One (of many) OSC applications for iOS devices is OSCemote, available in the Apple AppStore. Keep in mind that anyone connected to the same wireless network could potentially send OSC messages to your Ventuz machine and use the same control mechanisms as you. OSC does not contain any form of authentication. Which message names a device or application uses is usually stated in the specification or documentation of that device or piece of software. Each message contains an OSC address, a textual representation that specifies the name of the command, as well as a list of parameter values. OSC uses so called OSC messages to send commands over the network. Due to its simple and extensive nature, OSC has been used in various contexts to establish a simple communication between different pieces of hardware and/or software. Open Sound Control is an network protocol that has originally been designed as a replacement for the antiquated MIDI protocol which is still the standard for communication between music devices. The following will show you how to create a simple scene switcher using OSC. ), a particular simple and elegant one is to use a small, unobtrusive touch device such as an iPod Touch. While there are many ways to remote control Ventuz (see OSC, Remoting. This can be as simple as a panic button that resets the scene in case of problems or as sophisticated as an additional input device that allows the operator to influence the experience the audience has. The other channel is that of the operator running the show. For one, the audience views the scene on the main output device (for example a wall of LCD displays) and may or may not have a form of interacting with the scene (let's say a joystick). With large public installations in particular, often the situation arises that two channels of communication are required. This How To will show you how to use an Apple iOS device such as an iPhone, iPad or iPod Touch as a custom remote control for a Ventuz scene.
