What a cool device! New to me, and very interesting.
From a quick look at the manual
https://sleepycircuits.gitbook.io/sleep ... pno-manual I think it's almost certain that the Hypno can be used as an input to Magic, but it might need care/experimentation in the selection of the HDMI to USB video capture card. There's also the possibility of capturing the Hypno NDI output into Magic.
Using the HDMI video output
The Hypno video output is 720x480 at 60FPS from an HDMI connector. There are two requirements for successful HDMI capture:
1) The capture card will need an HDMI input capable of capturing 720x480 at 60FPS.
2) Magic needs to be able to set the capture card appropriately, unless the card can set itself automatically.
In my experience the second requirement may prove simple, tricky or impossible (depending on the complexity of the capture card). Some cards have non-standard settings, requiring a custom driver. Magic does not support these, even though other apps on the same machine work as expected with the same card. Chances are best if the card has only one input (in this case HDMI).
I use Magewell USB capture cards, which automatically select inputs and input video resoulution. I'll try to simulate the Hypno output and see if I can capture this into Magic on a Magewell card.
Using the NDI output
The Hypno has an NDI output too, and I believe this can be captured into Magic with the addition of a third-party module.

I have no experience of this, but there may be issues matching NDI versions, MagicNDI module versions and Magic versions.
There may also be differences in latency (lag) between USB and NDI capture. One may be noticably quicker, but I can't even guess which.
EDIT: I did a quick test using a
Magewell USB Capture DVI Plus card as the input to Magic. Magic could successfully capture a 720x480 60FPS input, although I didn't find a setting that got the aspect ratio exactly right. It might be necessary to add a Scale module with different settings for X and Y scaling factor.
I'm not suggesting that you use the same card - it's unnecessarily expensive and versatile, costing almost as much as the Hypno! The Hypno website mentions that capture is possible using cheap cards, but their example used OBS as the capture application. OBS can configure very many different capture cards, some of which may not be configurable by Magic.
EDIT2:
It would be helpful if you could specify whether you're using Mac or PC, as the capture methods are somewhat different.
EDIT 3:
Using the composite video output
Having read a bit further on in the manual I see that the Hypno also has a composite video output, which can be configured for PAL as well as the default NTSC format .The resolution will be inferior to the HDMI output, and there will likely be some colour fringing artifacts, but even a low spec composite video capture card should be fine for use with Magic. If the capture card can only accept a single composite input then configuration will be trivial and I would expect it to work in Magic provided it will work with your computer's OS.
