Get Sampler

The sampler is one of those things you set once and mostly forget - until you build a workflow that wants to switch between a fast distilled sampler and a high-quality one per profile. Get Sampler is WorkflowX's node for that: it resolves a sampler name from a Set Sampler node based on the active config, and hands it to your KSampler as a proper sampler_name wire.

The neat part is what it does not do. It doesn't hold a hardcoded dropdown - it reads the live sampler list from your ComfyUI installation, so a sampler available in your current build shows up as a real choice on the Set side and the Get output is a true typed socket your KSampler accepts.

How it works

Same keyed-resolution machinery as the rest of the typed Get family, with one twist that matters: the value type is ComfyUI's own sampler enum, pulled from comfy.samplers.KSampler.SAMPLERS at startup. So Set Sampler presents the actual list your ComfyUI knows (euler, dpmpp_2m, dpmpp_2m_sde, the cfg_pp variants, and so on), and Get Sampler returns one of them.

The routing is identical to Get Int or Get Float. Set Sampler publishes a sampler name under a key inside a ComfyUI group; a Config SelectorX marks groups Active/Bypass/Mute/Ignore per config; Get Sampler resolves to the Set Sampler in an Active group, last canvas id winning if several match. The resolved_value, resolved_config, and resolved_digest widgets are UI-managed provenance - leave them alone, they're the cache that makes profile switching work without a refresh.

Inputs and outputs

• key (STRING) - exact match against the Set Sampler key.
• resolved_value / resolved_config / resolved_digest (STRING) - internal, frontend-managed.
• Output: sampler_name - the live sampler dropdown type ComfyUI's KSampler accepts. Wire straight into sampler_name.

Because it's a real enum socket, this is one of the more satisfying Gets in the pack: there's no string-vs-enum mismatch to debug at the consumer.

Install

Part of WorkflowX-Configurator. ComfyUI Manager → search WorkflowX Configurator, or:

cd ComfyUI/custom_nodes
git clone https://github.com/haroonaslam/WorkflowX-Configurator

Restart, hard-refresh. No extra Python dependencies; the sampler list comes from ComfyUI itself.

Common issues

• "No Sampler value found for key 'x'." - no matching Set Sampler in an Active group. Check the key and the group's mode in the selected profile.
• A sampler you know exists isn't in the list. The list is read from your ComfyUI at startup. Restart after updating ComfyUI so the Get/Set nodes pick up new samplers.
• Wrong sampler after switching. Re-queue after changing config; resolution is at queue time, and the digest cache means no refresh is needed - just a re-run.

Keep it honest: this pack is young and lightly adopted. If you only ever use one sampler, skip this node. It shines when sampler choice is a real dimension of your profile matrix - say, a distilled fast path vs. a full-quality path in one graph.
