I don't have Sonoma, but I just ran a test with Izzy 4 and Ventura on a MacMini M1, and broadcasting worked for me.

I just did a test on macOS Catalina, with a Elgato Cam Link 4K (same device as you I believe), with both Isadora 3.2.6 and 4.
In both cases I was able to select the device and start live capture getting the thumbnail updating with the live input right away.

How do you have the device connected? Do you have it sharing an input via some hub? If possible be sure you are connected as directly to the mac as possible.

Hi Jonathan!

If you click on the second button, next to the yellow text it will open up the Audio dialog setup. Could you attach a screenshot of that dialog as well?

Because it seems that this device only has 8 outputs, according to the operation system

@stephan-bergmann

Lots of questions here :) A Serial device like the USB-DMX Controller (could you link which one you are using?) needs to be enabled in the Serial menu of Isadora.

1. Communications > Serial Port Setup
2. Select your Device on Port 1
3. Close the dialog

Now that we have our device setup complete, we can actually start building the patch.

A great starting points for this is the following patch:

https://troikatronix.com/add-ons/dx-dmx-universe-enttec-compatible/

Download this to your machine, and you will see that a couple things / actors are setup for you in Scene #2

The ones that you need are:

1. Matrix Value Send
2. Matrix Value receive
3. Send Raw Serial Data

Matrix Value send allows you to attach a fader / numeric value to a 'input'. You will see in this actor something called 'channels' and 'channel 1 - channel 2 - channel 3'. This channels are important! They are the start-address of your fixture. You can change this start address at the light fixture in the DMX Menu.

Please be aware that the cheap lights sometimes require a 'power reset' before changes take in effect. Simply unplugging / plugging the fixture back in should cause it to work if it didn't apply when you entered your DMX start address.

Matrix Value Receive basically 'encodes' the message and allows us to format in such a way where the light fixture understands what we are trying to say. It makes the message 'DMX' compatible.

Send Raw Serial data is sending the value to the USB-Serial Device

Hi all.

I already read all DMX related articles here...but I don't know what actor to use to trigger the Spot.

On my serial port setup I selected my USB-DMX controller.

So, am I using "ArtNet Send", "Send Serial Data", "Send Control", .... and with which data to fill in (Channel of the Spot is 21)?

And once I can (how to?) switch on / off the Spot via DMX commends, how do I change color, fadings, ...?

Thanks a lot in advance for your help.

Hi,

I need to output multiple channels of audio from Isadora 4.0.1 on an M1 Mac OS 11.7.10 (same problem also with different M1 Mac OS 12.1). I am using a Fireface UC audio interface which has 18 outputs.

Whatever I try, Isadora can only see the first 8 audio outputs of the audio device. I can confirm that other software running on the same computers can see all output channels. Even when I create a Mac OS aggregate device that includes the Fireface UC, then select that aggregate device in Isadora, only the first 8 channels are accessible.

Is there an option somewhere in Isadora I don't know about that can unlock more than 8 audio output channels? Or is this an intentional limitation of Isadora 4? I cannot find any reference to this in the documentation or previous forum posts.

Many thanks in advance.

Jonathan.

Yes, good catch, thanks. Edited my original post :)

Also the Timed Trigger approach is a good one, and I suppose it does use fewer actors

Initialize the 'loop' input of the Movie Player actor as 'off'.

posterizer effect

On macOS there are the QC Posterize and CI Color Posterize actors, but they're not ours, we just pull them in from Apple's architecture and they're ancient and inefficient so I usually recommend not using any of the CI or QC actors. If you do go down that route you'll want to use the Video Converter actors (GPU to CI, GPU to QC, CI to GPU, and QC to GPU) to make sure you're using GPU video wherever possible.

@iridescence

@dbini's solution is great. A few further points on that:

1. Attach an Enter Scene Trigger actor to the 'run' input of the Timer actor.
2. Put a Calculator actor dividing by 1000 between the Timer actor and the Comparator actor (to convert milliseconds to seconds, since the Comparator is set up in the screenshot to look for 600 seconds = 10 minutes).
3. Initialize the 'value 1' input of the Comparator actor as '0'.
4. Initialize the 'loop' input of the Movie Player actor as 'on'.
