@bonemap said: The direct routing with Movie Player 'audio trks' parameters appear more effective for my purpose. The tutorial made a lot of the process clear and I have found a workable multichannel audio solution to move forward with. Thanks for your help. Note also that a solution inside Isadora that allows this kind of routing is at the tippy top of our priority list. It will come relatively soon now that we sense that Catalina compatibility is in the bag.Best Wishes,Mark

Hi Thanks, the projector is the Optoma ZH406ST (https://www.optoma.co.uk/product-details/zh406st) its a very new projector and says is has PJlink capabilities.

DusX- thanks, understood! 

@markHello Mark, my problem was already on 2.6.1 because I had to adapt my patch from 2.5.2 when I had to move to Mojave for other softwares. The random problem surprised me and it's the first time I have a bug during a show with izz in nearly 13 years.

@mark  [OFF TOPIC] Situations like this always take me to a philosophical point: how far do we go with Isadora in terms of things supporting certain kinds of features? Personally I rarely have expectations about what new features are added to Izzy. But I would like to have the insight to implement/deploy whatever existing features or functionality are lurking there and waiting in Izzy - as a potential.  Providing enough description to uncover the potential of a specific existing module is as powerful as adding new features IMHO. That is why the revelation about the AUMatrixMixer is so astonishing. Yes, it is logical for an audio technician - and anyone else, once the realisation ‘that audio, unlike video, carries multiple channels in a single stream’ and 'panning to separate individual tracks that have been forced into stereo pairs' is applied to unpack the problem. This simple statement unravels a whole chain of sequences and connections that resolve the implementation of multichannel audio. No matter how obvious that statement might appear to be! I think, for me, I do have an expectation that what already exists in Izzy is a ‘supported’ feature and functional to the highest limit of its potential. To that end I will make noise when it appears that some parameter function is broken or appears to be not functioning as expected. There are existing 3D modules incorporated into Izzy therefore the expectation, from a user perspective, is that they are supported. When I first approached using the 3D modules, I had no idea or insight into the extent of their potential. The joy of discovering what they are capable of producing has been a source of inspiration and a catalyst for imagining a way of working with Izzy that has lasted many years. I have become accustomed to the statement that ‘3D is not a priority feature’. But, I would say that the existing 3D modules have so much ‘hidden’ potential that perhaps it is not a question of adding new 3D features, it is more about ensuring the current offering is functioning to a high level potential. best wishesRussell

You may also want to change the Direction on your Keyboard watcher to "Up" to prevent multiple triggers (since holding down the spacebar too long with the Keyboard Watcher set to "Down" can trigger the Keyboard watcher in the Scene your transitioning from AND the Scene you're transitioning into).Adding a Multiblocker actor between the Keyboard Watcher and the Jump Actor is another way to prevent accidental activation of more than one Jump actor.

Hi @mark,That is amazing! so grateful for the detail that you have provided in the tutorial, especially considering, as I understand it, that there are changes to how Isadora will handle multichannel audio in the Catalina and cross-platform future.best wishesRussell
