@dusx Thanks for the lightning fast reply! I missed that CPU to GPU converter actor, sounds like the right solution for me. I'll try and let you know how it goes in case the solution interests someone else.

I keep getting the error : "Input of fragment shader 'circle' not written by vertex shader" every time I try to input "circle" into any other part of the code.

I've tried "#define circle 2.0" or "float circle = circle" but I either get the error message or the code compiles into a blank screen.

Again, I would be very grateful to anybody who would be able to chat in real time about this project.

Thanks!

ps sorry for weird formatting

@dusx thanks a lot - all sorted! cheers, Dave

Does the device appear in Apple's Audio Midi Setup Application?

@dillthekraut

If memory serves we already have this bug logged and the workaround is simply to add a fade time of 1 millisecond.

Best wishes,

Woland

@dusxThanks,

I still don't know wow to do that in Javascript, bit it is nice to know that is is possible.

Thanks again

@benju Didn't you do something similar for the large spinning imagery spanning multiple beamers for Hexploitation? I think I remember you saying you used Virtual Stages. Do you think your approach would be applicable here?

Exactly what I need! Thank you Woland!!

sorry that I did not react for quite a while: my rehearsals are just very time-consuming and challenging.

thank you all for your answeres - that's very helpfull!

@Woland

as always from your side that's a very profund answere. thank you very much, especially for all your practical suggestions how to deal with my problem.

@Mr_J

also this is helpfull as a direction for me.

@Josafat

this is a very interesting observation - thank you for sharing it.

so far I am still working in 3.0.7 but I should come to a decision in this week and I have the tendency to follow the first suggestion of Woland (even if the internal hardrive of the old macpro is only 500 gb) and try the bootable partition with a newer os. as I jumpt from high sierra with a new M1Max-macbookpro directly to monterey - which works ok for me apart from the incredibly annoying orange dot - I'd be be very curious to know if you have a clear recommendation for mojave, catalina or big sur?

Value Changed actor and am loving its uses (BTW it's not listed in the v3.0 manual, which i think is the latest one)

 This actor is rather new. We are working on a Manual update, so it will be included in the near future ;)
You can however read about it in the Isadora release notes. https://support.troikatronix.c...

@jfg Thank you so much for quick reply! I actually discovered this myself after sending the question. Thanks for confirming the simple technique.

Cheers, David

Hi there @hagaizenberg,

If you wish to apply an effect to all your stages, I would use a Broadcaster and Receiver and a concept that we like to call a Master Scene. You can also use a virtual stage (Stage Setup > Add an Virtual stage). This is basically a virtual screen that you can grab again with the actor "Get Stage Image"

@peter this night not be the easiest thing to do. You can programmatically control the screen brightness on iOS see here: https://stackoverflow.com/questions/8936999/how-can-we-programmatically-change-the-brightness-of-the-iphone-screen

you could make a very simple iOS app that runs as a background service and accepts an OSC message from isadora. OpenFrameworks comes with an osc example for iOS, if you add the needed objective c code from page above you are almost there. You just need background activity. 

@Vidasonik 

You can also use the OSC Transmit/Receive and OSC Multi Transmit/Receive actors to send data between computers on the same network (so long as you know the right IP address for each computer)

@merni

I've already got a feature request logged about actors that interact with Q#'s, so I'll add this to it.

@woland

Hi, I found a solution to but Traktor Kontrol to Maschine MK3 input with RCA and Plug Adapter.

@woland

Hi L,

A 3d model file of a Brain neuron, decimated for use in Isadora with rights approval from https://eyewire.org - Not a waveform but a great asset associated with brain anatomy. Let me know if you are interested.

Best wishes

@aline

its probably better to use different Movie Players in the same scene and trigger them according to when you need each movie to play. You can add Video Mixers or Selectors between Movie Players and your Projector(s) and trigger values to these using various methods, such as Envelope Generator, Trigger Delay or Comparator.
If you initialise the speed of each Movie Player to zero, it will not play until you trigger a value of 1 to it.

thanks @jfg @bonemap . Reassured to find it's not just me, though disappointed there's no apparent solution at the moment. Let's hope for some expansion in this area in future updates...

@dusx

thanks a lot for your very useful supplement. Since I have always used the Actor OSC Multi Listener, I had not paid any attention to the fact that when renumbering the ports, Isadora jumped for e.g. from 4 to 6 when there were two values at 4.

Thanks again
