“Complete set” wasn’t the best choice of phrase; I just meant that Cortex has both input and output converters, and units to do most of the techniques mentioned in this thread so far (color mixing/negative/solarization, keying, luma extraction, ramps and sync.) If you want to run video signals through your audio modules (like running the red channel through a filter) then Cortex will enable that.
You don’t necessarily need Bridge for 5V/1V conversion for Memory Palace, its CV inputs can be switched to take 5V so you can manipulate its parameters with your audio gear directly. MP takes control in, but it doesn’t break out the video for any processing by other modules.

13 external voltage control inputs with buffered attenuators for all primary parameters. Switchable from LZX 1V DC to EuroRack 5V DC voltage scales from the settings menu.
It sounds like Andor + MP alone would be enough for you, functionality-wise, except you still need something to convert the Andor output (HDMI or composite) to the MP input (1V). Your choices there are Visual Cortex or the forthcoming TBC2 module. If you want clip playback and manipulation completely within Eurorack, the future Orion series sampler module might be more up your alley than the Andor, but no details on that sampler have been released yet. Presumably, though, it will be able to output 1V straight into MP and give you a version of your workflow in two modules.
