Per-projector and per-fixture delays
Posted: Sun Jul 21, 2019 9:42 am
Are there any ways to compensate for projector input lag in Madmapper, on a per-projector basis? Or for DMX/Artnet fixtures? I wasn't able to find any third party syphon-delay application out there, to do this externally.
When I'm driving MM from Ableton Live -- for bpm as well as triggering cues -- I can delay the audio in Ableton to compensate in general, but this doesn't work if I'm driving a high-delay projector alongside low-delay ones. I've recently run into issues using different types of projectors simultaneously, where the input lag for one is 16ms while the other is 80ms. And have definitely had problems when I throw LEDs into the mix, as they are typically quite fast to respond.
It would be great if Madmapper allowed for configurable delays for individual projectors as well as fixtures, though I understand this would likely require allocating some memory to achieve this. This would allow users to delay the faster projectors and deal with global delay externally (say, with Ableton Live). If we can't get DMX fixture delays in MM, then per-projector ones would suffice, as you could use a projector-like output to drive the LEDs w/ internal syphon routing.
Other software like Resolume support per-projector delays already. I think it would be a great addition to MM.
