Every once in a while I make a new node. If I'm using it then I'm putting it here. Good luck.
Detects BPM and musical key from an audio file using the Krumhansl-Schmuckler algorithm. Outputs BPM (INT), key, scale, and keyscale (e.g. "G minor") as well as an AUDIO output. Comes in two variants:
- Audio Analyzer - accepts a raw file path string (for minimalists)
- Audio Analyzer Upload - uses ComfyUI's built-in file picker with audio preview
Batched image loader that processes multiple folders sequentially. Accepts a multi-line list of folder paths and auto-increments through all of them batch by batch, outputting the correct folder path with each batch. Includes sorting options (alphabetical, by date, random) and a reset button.
Captures Python environment info (PyTorch, CUDA, Triton, Sage Attention, xformers, CLI args) and saves it into the node and your output metadata. Useful for tracking down why saved workflows produce different results on different setups or after package updates.
Features:
- Populate button - Click "Populate Environment Info" to collect data immediately without running the workflow. Recommended on first load so your first queue already contains metadata.
- Change detection - After each run the node compares the current environment against the previous snapshot. A dedicated diff window shows exactly what changed, highlighted in red for changes or green for stable.
- Persistent comparison - The previous snapshot is saved with the workflow, so change detection works across sessions.
An incrementor with a reset button and adjustable step size.
(Note: The value on the node itself shows the NEXT value. This is normal.)

Indiscriminately counts files in a folder and displays it on the node itself (by INT out).

Search for "Allergic Pack" in ComfyUI Manager and install the most recent version (don't do nightly unless you want to mess with your security levels). Dependencies will be installed automatically.
comfy node install AllergicPack
Clone to "custom_nodes" and install dependencies:
Windows (Portable Version):
cd ComfyUI_windows_portable\ComfyUI\custom_nodes
git clone https://github.com/usrname0/ComfyUI-AllergicPack.git
cd ComfyUI-AllergicPack

cd ComfyUI/custom_nodes
git clone https://github.com/usrname0/ComfyUI-AllergicPack.git
cd ComfyUI-AllergicPack
pip install .
