Big ComfyUI graphs turn into spaghetti fast - model, CLIP, VAE, conditioning, latent all trailing wires across the whole canvas to wherever they're needed. A bus fixes that. This node packs up to eight arbitrary connections into a single PIPE_LINE, so instead of eight wires crossing your graph you route one, then unpack it later with CR 8 Channel Out.

It's Comfyroll Studio's take on the bus/context pattern (Suzie1 / RockOfFire) - the exact same idea as rgthree's Context nodes: carry a bundle of connections down one wire so the graph stays readable. It adds no generation capability; it's pure organization.

How it works

Each channel is typed *, meaning it accepts anything - a model, a latent, an image, a string, whatever. You plug your wires into ch1 through ch8, and the node emits a single PIPE_LINE that carries all of them together. The channel number is the contract: whatever you put in ch3 here comes out of ch3 at the other end. There's no naming, just position, so pick a convention and stick to it.

The optional pipe input is what makes this composable. Feed an existing bus in, and this node merges your new channels onto it - so you can build a bus up in stages across the graph, or top up a bus that came from an upstream module, rather than always starting from eight empty slots.

The inputs that matter

  • ch1–ch8 - the (optional) connections to bundle. Any type. Empty slots are fine; you don't have to fill all eight.
  • pipe (optional) - an incoming PIPE_LINE to extend. Leave it unconnected to start a fresh bus.

Output is the single pipe (PIPE_LINE) plus the show_help link. Route that pipe wherever the bundle needs to go, then unpack with CR 8 Channel Out.

How to install it

  • ComfyUI Manager: search Comfyroll Studio, install, restart.
  • Manual: cd ComfyUI/custom_nodes && git clone https://github.com/Suzie1/ComfyUI_Comfyroll_CustomNodes.git, then restart.

No models - it's pure plumbing.

Common issues

The one rule that saves you grief: channels are positional, and the In and Out nodes have to agree. If you unpack ch5 expecting a VAE but you loaded the VAE into ch4 back here, you'll wire garbage into the wrong socket and get a confusing type error downstream. Keep a consistent channel map for your whole graph.

Second thing - a bus doesn't unload anything. Bundling a model into a channel doesn't save memory; it's a routing convenience, not a performance trick. And because the channels are untyped *, ComfyUI can't warn you at connect time if you cross wires; the mismatch only surfaces where the value is finally used. If the node's missing from your menu entirely, that's the Comfyroll pack failing to load, which is a pack-level issue rather than this node.
