You are not wrong in finding the routing control string formatting confusing. I have found the help text has a number of errors. 
I have tested in Isadora 4, and can confirm the volume controls work, but require a format that the help text is incorrect about.
Here is a formatting string for the Text Formatter:

 "1:1@" P1 "; 2:2@" P2

For control by percentage the % sign can NOT be used. The string format expected is: 1:1@0; 2:2@100

Note also, that the separator is a semi-colon not a comma as stated in the help.

I am entering these discrepancies into our bug tracker, and will ensure they are fixed for the next release.

A feature, you may not have noticed is that if you use the routing widget (click the actor grid Icon) and adjust the volume per channel there, the actor will create the input router string. This is the easiest way to get a working reference string.

@juriaan @fred @woland @bonemap @everyone I hope you don't mind me bumping this thread, I found the information extremely useful, but seeing as it's been 8 years since this has been discussed I wonder what new developments I should consider.

I primarily work in an education setting, and I would like to be able to create my own local network for wired and wireless access. 

I'm using Mac computers (Isadora), Arduino and Pipo interfaces, Birddog cameras (controlled via the VISCA PTZ actor), Luxonis Oak-D camera (POE), audio sent over Dante, plus NDI and OSC.

Can I purchase a router with multiple poe ethernet ports which also offers wireless connection with good range, or do I invest in a wireless router and a separate switch? Hoping for your recommendations.

Many thanks for everyone's help.

Best wishes, Simon

@reload2024 Yup, managing EDID is fun. The high-end media servers (disguise, Pixera, GreenHippo) all manage these with additional hardware and software (one company uses a mini Raspberry Pi hidden away in their cases just to manage EDID). 

It sounds like you need/should keep the Mosaic on then. I would use the tools within Isadora to achieve what you need. Might be worth making a template to map out the outputs - if that makes sense? All you are doing really is managing the pixels and where they go. Keep us posted, happy to help if/when I can.

Hi,

It's the same process: right-click on the checkbox, select "Add Control," choose "OSC," then "Learn," and send the OSC message from Isadora. Sending 0 or 1 will activate or deactivate the quad.

Best regards

@skulpture  With my video card NVS810 it supports mosaic but not their other edge blend etc tools.  I can set the overlap of the projectors but that doesn't do any blending its intended for monitors I guess.  So the reason I use mosaic is because when I just use the projectors directly, even with EDID minders plugged into them, all sorts of problems come up.  Sometimes these edid minders change their resolution settings for no reason, or I have some obscure problems at critical times and after hours of debugging I find out its the EDID profiles.  And if I don't use the EdID minders, windows shuffles up the display order after every reboot.  Using Mosaic it keeps perfect track of the displays it always works.  

Thanks for the workflow suggestion I'll check it out.

@gaspar

OK, I have found the cause here. You are passing a value thru the user actor. It assumes there is some processing internally so the value is processed. 

If you instead turn the input and outputs to trigger types the trigger is not passed.

@reload2024 Yes and No.


Nvidia Mosaic is basically doing its job at its GPU level. So it has created a lovely big canvas for you, all edge-blended and lovely. But what you want to do is treat them individually.

A few options:

1) Don't use Mosaic? Then you will see everything individually. 

2) Treat the output as a big canvas and then use the tools in Isadora to 'cut out' the bits you need. Look at the crop actors, Matte, Matte++ and look at the Virtual Stages for sure. They can be confusing, but use 5 virtual stages and then bring them all back together using "Get Stage Image" and comp them back into your 1 giant stage output.

I am able to change the opacity of a given quad in Madmapper sending an OSC command from Isadora to the quad's opacity parameter address (/surfaces/Quad-3/opacity).

However, the venue technicians prefer a more crude way to activate/deactivate entire quad from Isadora. In other words they would like to tick off/on the checkbox in the picture:

The problem with this approach is that in order for a given MadMapper parameter to be controlled by OSC signal, one has to attach an "Osc Control" to it in MadMapper. In the case of quad's opacity one right-clicks on a opacity slider and selects "Add OSC control" option from the popup.

Has anybody achieved this in the case activation/deactivation?

Thanks.

P.S. What would be even better is to fade from one Scene to another Scene in Madmapper, using OSC.

I have 5 projectors bundled into a single NVidia mosaic display.   This virtual display of course is the full width of my 5 displays, but I was hoping to use the grid calibration tool in Isadora even though they aren't separate devices anymore.  Is this possible?

Sound Distribution Problems

Hi, I tried to load my patch for testing sound distribution, which worked fine in Isadora 3. Today, working with Isadora 4 and on Win 11, I got the error message: Isadora has experienced an unexpected error. (ID = -19)

So I tried to recreate sound distribution in a new file. It works fine, as long I do routing without levels, e.g. "1:1,2:4" etc. When I add the volume parameter with "@" sign, the routing doesn't work. e.g. "1:1@50%"

I think, I'll need help with the routing syntax. Is there a different routing syntax?

Thanks for your help!
