Motorway 9x5

Motorway 9x5 is the ramp that starts to look like a small control panel: nine wildcard inputs (A through I) load into the Motorway, and five pull-port outputs (A through E) let you surface a fifth of the state at once. It's the [inputs]x[outputs] naming pattern working as advertised - bundle heavily, query liberally.

Here's the mental model that makes every one of these nodes click. The Motorway is a bag of key→value pairs carried by one wire. You type a key next to any input and the value goes into the bag under that name. Outputs don't echo inputs - each output is a little query that fetches whatever key you typed into its key field, wherever that value was set. So a 9x5 doesn't have to be "these nine in, those five out" in any positional sense. You can store model, clip, vae, positive, negative, seed, steps, cfg, and a lora stack at the top of the graph, then use this node mid-graph to pull out, say, model, positive, negative, seed, and steps and wire them straight into a sampler. The positions don't line up; the keys are the contract.

That's also why the five-output version is worth having at all rather than always grabbing the biggest node. Five is "everything a sampler wants" - model, positive, negative, seed, steps - in one place, which is a shockingly common need. It's the ramp you put right in front of a KSampler.

Under the hood it's all the same custom type: values stored under sha256 hashes of your key strings, the bag cloned at each node so branches don't bleed into each other, and a loud 'MotorwayClass' object has no attribute 'hash_' if you ever read a key nobody wrote. Treat that error as a typo detector.

Install the pack however you like - ComfyUI Manager (search "agilly1989") or:

cd ComfyUI/custom_nodes
git clone https://github.com/agilly1989/ComfyUI_agilly1989_motorway

Restart ComfyUI and you're done. No models, no pip requirements, nothing else to fetch.

Same family warnings: keys are exact and case-sensitive, the pack is a one-person beta that the author openly says can break, and older releases had a startup-crashing clone experiment that's since been removed - if ComfyUI won't boot after an update, that's the pack to suspect first. The 9x5 is a great middle ground; you'll rarely want more exits than a sampler has inputs.
