	~~== INTRODUCTION ==~~

	~~In this tutorial we look at how to synchronise Iannix with Max MSP via Open Sound Control (OSC).~~

	~~'''What is Iannix?'''~~
	Iannix is a graphical open source sequencer that has the ability to sync with a variety of real time software environments such as Max MSP, Pure Data, Super Collider etc. via Open Sound Control (OSC). Iannix is useful as it has a variety of input/output capabilities however for the purpose of this tutorial we focus on how to send values generated in Iannix to Max MSP in order to familiarise ourselves with the Open Sound Control protocol.

	~~'''What is Open Sound Control?'''~~
	~~Open sound control is a protocol for communication among computers and multimedia devices. It can be utilised to communicate data between different software platforms locally and remotely.~~

	~~'''What is Max MSP?'''~~
	Max MSP is a visual programming language that enables you to construct complex interactive systems for music and multimedia environments. It is particularly useful for the performance platform in order to design custom responsive audio environments from incoming visual data.


	~~== PREPARATION ==~~


	~~Ensure Iannix is installed. http://www.iannix.org/en/download-iannix/ <br/>~~
	~~Ensure Max MSP is installed. Demo version here: https://cycling74.com/downloads~~

	~~== Configure Iannix to send data via OSC ==~~


	~~1. Open Iannix. <br/>~~
	~~2. In the inspector go to the configuration tab and select network as pictured below.~~

	~~[[File:Configure.png\|400px]]~~

	~~3. Make sure Enable OSC is on. <br/>~~
	~~4. In the Default IP tab enter the IP address of the receiver. Use the default IP 127.0.0.1 if you are running both programs on the same computer. <br/>~~
	~~5. The default port for sending data out of Iannix is 57210 as pictured. <br/>~~

	Now you are set up and ready to send data to Max MSP. In order to generate some values to be sent to Max we need to create a new score in Iannix. You can either select one of the examples in the files menu found in the inspector or you can create a new score from scratch. <br/>

	~~For example:~~

	~~<videoflash type="vimeo">176951012\|400\|300\|</videoflash>~~

	~~Now we are ready to receive values from Iannix in Max MSP.~~


	~~== Enable Max MSP to receive incoming OSC data from Iannix ==~~

	~~1. Create a new patcher. <br/>~~
	2. Create a new object in the patcher window and type into the object box '''udpreceive'''. <br/> **'''udpreceive''' is a built in Max MSP object that receives OSC messages transmitted over a network. <br/>
	~~3. In the '''udpreceive''' object we define the port number declared in Iannix i.e. '''udpreceive 57120'''<br/>~~

	~~[[File:values.png\|400px]]~~

	4. In order for us to separate and route the array of messages we receive from Iannix we can create another object '''route'''. i.e. route '''/trigger /cursor''' and patch this to the outlet of the '''udpreceive''' object. We use the arguments '''/trigger''' and '''/cursor''' because these are the identifiers named in Iannix for bundling the values sent demonstrated in the above picture. <br/>
	5. It is then good practice to use the '''print''' object in Max MSP to get an idea of the values being received. In order to do this you should patch the '''print''' object to the '''route''' object outlets that match the arguments '''/trigger''' and '''/cursor'''. This allows us to see how we will manage the incoming data.<br/>
	~~6. Press play in Iannix and see what values are coming into Max MSP. <br/>~~
