Hi Eric!
How are you planning on playing back the data? What application is this for? If it is to use in an S-Play then the data needs to be recorded on an S-Play.
Controller-agnostic - i.e. playing back with any controller that has an SD card. Could be Enttec DIN Pixie, but more likely LeDMX, or Advatek, or Raspberry Pi LED Hat, etc.
Actually not a DIN Pixie, it has internal storage but it's not SD, plus apparently it's ridiculously tiny? Datasheet says
"show playback using inbuilt flash memory (4000 frames [~100 seconds])"
Hi Eric! Unfortunately there isn't a way to do that. There isn't a system-agnostic file structure for that kind of data so it can be imported and played back. For all the systems you listed, I believe you have to create the content or record it in on the hardware itself.
Well, FPP software can record from ELM (or any ArtNet source), and used with any FPP compatible controller, but as I mentioned internet chatter says it's not that reliable.
Do you know of any LED controller on the market that can record/play from SD card and also has audio output? The only thing I've seen is Raspberry Pi Hats used with FPP, or ESP32 controllers flashed with ESPixelStick V4 (beta) plus some DIY work. Nothing professional. Seems like a lot of people would want this...

Is it possible to record LED patterns to an SD card mounted on the host (ELM) computer)?
I know the S-Play can do this, but I don't want to buy a whole piece of hardware when the computer is already capable of writing to an SD card.
I know I can also use controllers that have built-in recording (e.g. LeDMX), but I need to use some other controllers without this feature. There is also other playback software like FPP but their recording features are limited - for example, they require FSEQ files, so I would need some utility to convert ELM output (ArtNet or sACN), which at the moment is not reliable.
