Simple Router not in toolbox in SigmaStudio both 3.11 & 3.12

Question

Hi, 
 I cannot find the simple router tools in the toolbox in either of the installed versions of SigmaStudio. 
 I am trying to build a mix matrix like this 
 https://wiki.analog.com/resources/tools-software/sigmastudio/toolbox/mixerssplitters/audiosignalrouterindexselectable 
 Am I supposed to use NxM Mixer ( non-linear ) ? 
 I've made an 8x8 box with NxM mixer but it looks bar bones ! where is the I2C controls for this so I can control the matrix from my 
 MC ? 
 sorry I am new to SigmaStudio so this is probably a very stupid question.. unless flexible routing is not possible with the AD1941 dsp IC ? 
 I'm running windows 8 64bit and both versions of the software installed without error. 
 any clue would be much welcomed

Hello Ben, 
 Using the NxM mixer will do what you are trying to do. The routing capabilities in the ADAU1446 have more to do with hardware routing inside the part without using the DSP. They can be changed after booting if needed. I think the AD1940/AD1941 may be enough for your needs. (I don't know everything about what you are trying to build) 
 As far as controlling it from your MC. This is a much larger topic but it is possible to control any control inside your project from the comms port. When you are using SigmaStudio and you are controlling the part in real time you can watch the capture window and see the commands being sent to the part to change the controls. This is what you need to send. There are some details to be aware of. 
 If you change the project, the address of the controls may change and so your MC code would need to be updated. 
 You must follow the safeload procedures etc. 
 Have a look at this document from the Wiki page that talks about this. 
 How do I create the microcontroller code to interface to my SigmaDSP? 
 There are also other posts about this on the forum. There is a section on the forum for SigmaDSP and SigmaStudio. It is a sub topic under DSP.
