The first 4K video synth is on the way, as a power user of the HD version, I fully recommend this visuals all in one platform, the Recursion Studio 4K! It’s a blast to run LZX or other video synths output through one of these as well, and it can accepts CV control signals (unsure if it can handle LZX CV ramps, may not have enough bandwidth on those inputs at 1 MHz).
It also runs in 720, 1080, and 1440 in 60 fps.
Check out today’s livestream on their YouTube for more info.
