I've been working on some DMX tools and this has stumped me. I'm trying to create a chase effect to be used with multiple fixtures.

Here's a GIF with a reference: https://makeagif.com/i/wjXi7H (the line of LEDs to the left of the stage)

I tried using the wave/envelope generators, but I feel that there are better ways to accomplish that smooth effect, of a sort of "shadow" crossing the light stream. Any ideas?

Thanks, I've now logged this.

Hi,

Apologies for being annoying with vague descriptions. I have tried again to recreate the crash and it was not difficult recreate with the combination of the actors in the gif capture here. It appears to be associated with the use of the Matrix Color Send and the presence of a video stream. It happens when the Matrix Value Receive input 'max in chan' has a value over 2050.

best wishes

2050

~250 (it's 287 in your screenshot) or ~2050?

 Anyway, it'd be great if you could send us in a patch that causes the problem (as well as any relevant things you've changed in Isadora Settings/Preferences) in a support ticket so we can more easily log this.

Hi,

I have a repeating Isadora application crash on the input 'max in chan' of the Matrix Value Receive actor, when the input value is above or around 2050. Perhaps not an urgent case, but just in case anyone arrives there, like me, stress testing video sampling for a particle system. It appears sampling at higher rates is a loading issue but not sure if loading is the cause of the application crash. Bug report sent.

Best Wishes,

Russell

As far as I know, you'd only potentially have trouble if you intend to use the Screen Capture actor with Isadora 4 on Tahoe. We've not had any other reports of issues with Isadora 4 and Tahoe as far as I know. 

That being said, technically macOS Tahoe is not currently a supported operating system for use with Isadora 4. (This doesn't mean that Isadora won't work at all on Tahoe, it just means that we are still in the process of discovering what we need to update in order to unbreak the things that Apple broke for us in Tahoe.)

Just to follow up on this: I will start to do a new project, and I would like to use my M1 Pro MacBook Pro which already has Tahoe on it. Will my Isadora license be a good solution for this in the meantime or is it not ready to use for this?

Thanks!

Got it, thank you so much!
