I’m guessing no, based on the type of things people have done to try and get an exploded view of the octatrack screen which are like mounting a camera and sending the camera view of the OT screen to a tablet screen.
Unfortunately I don’t believe the pixel matrix of an LED or OLED screen is in any way comparable to the video output of devices that use component or hdmi or whatever other type video out.
I don’t know if you remember but back in the day a couple of roland devices like a digital workstation and one or 2 synths had a similar feature (video out) and as I remember it required a lot of other internal components and a provision in the firmware that would translate the signal so that it could be sent to a monitor.
I’m sure someone with better information could give you a more comprehensive answer, but I’d say it’s safe to assume no, that’s not going to work. Would be cool though if someone made something with that capability as an in-built feature.
No problem, hope it works out for you.
