SWITCH OSC Control @ vrch.ai

SWITCH OSC Control is the pack's answer to "I need eight on/off buttons in front of me." It watches eight separate OSC paths and turns each into a boolean output, so a tablet full of toggle buttons becomes eight switches in your graph. This is the node that makes live control of anything conditional feel natural - flip a button on the tablet, and a whole branch of your workflow turns on or off.

How it works

You give it a server_ip and port (8000 default) plus eight paths - path1 through path8, defaulting to /toggle1 … /toggle8. Your OSC client sends 1 to a path for ON and 0 for OFF, and the matching output flips. The outputs are literally SWITCH_1 through SWITCH_8, all booleans. One message, one switch, zero state to manage on your side.

The crucial detail is that these are value-based, not edge-triggered: you send 0 or 1 to set the state, and the node reflects whatever the last message said. That means TouchOSC toggle buttons work perfectly - each press sends the opposite value - but it also means a momentary button that sends 1 on press and nothing on release won't behave the way you expect. Set your client to send both states.

A sane beginner setup: load the pack's bundled TouchOSC panel (comfyui_osc_control.tosc), which already speaks /toggle1-style paths on port 8000. Point it at your machine and the switches come alive without any path renaming.

Wiring it

Eight booleans give you a lot of routing for very little effort:

• Feed them into Trigger Toggle nodes if you want them to latch into a state that survives a message disappearing.
• Wire them into conditionals or TEXT Concat OSC Control to build a prompt out of active tags.
• Use them to bypass a whole segment of the graph - mute the upscaler, drop the LoRA, switch between two branches.

Installing it

Standard pack install:

1. ComfyUI Manager → search ComfyUI Web Viewer → install.
2. Manual:

   cd ComfyUI/custom_nodes
   git clone https://github.com/VrchStudio/comfyui-web-viewer
   pip install -r requirements.txt
   

   Windows portable: python_embeded\python.exe -m pip install -r ComfyUI\custom_nodes\comfyui-web-viewer\requirements.txt.
3. Restart ComfyUI.

The python-osc dependency arrives with the pack. First install is slow because the requirements also bundle the optional Music2Emotion stack; that's unrelated, let it finish.

Gotchas

Same network trap as every OSC node here: the default server_ip of 172.17.0.2 is a Docker-bridge address that means nothing on a normal desktop. Set it to 127.0.0.1 or your LAN IP. And don't skip sending 0 - a switch that never receives an OFF will stay ON forever, which is exactly the kind of thing you discover mid-set. Enable debug while testing and watch the console confirm each path is landing before you trust it live.
