+## An Example I Pasted Together
+In this [workflow](https://github.com/lks-ai/ComfyUI-StableAudioSampler/blob/main/workflows/audio-space-exploration.json), I got random `cfg_scale`, `sigma_min` and `step` values making variations on the same 16 beats; same `prompt` and `seed`. **VOLUME WARNING!**

 - Can still use HF env key if you want
 - Generates audio and outputs raw bytes and a sample rate for use with VHS
 - Includes all of the original Stable Audio Open parameters
 - Sampler outputs a Spectrogram image (experimental)
 - Can save audio to file
+- New Prefix Templates for save file naming
+- Outputs a temporary `wav` to `temp/stableaudiosampler.wav` you can use for looping like in [this video](https://www.youtube.com/watch?v=_eR6tP-c8W4).

+### Example Workflows
+#### [Exploring Same Prompt and Seed](https://github.com/lks-ai/ComfyUI-StableAudioSampler/blob/main/workflows/audio-space-exploration.json)
+
+The part I use AnyNode for is just getting random values within a range for `cfg_scale`, `steps` and `sigma_min` thanks to feedback from the community and some tinkering, I think I found a way in this workflow to just get endless sequences of the same seed/prompt in any key (because I mentioned what key the synth lead needed to be in).
+
+With the new save prefix templating, it makes it easy to just look at the file and know what settings (since wav doesn't have PNGinfo)

+If you get the `progressbar` error, you can use our new utility from the latest update.

+In this screenshot, you see `protobuf` but that is only because I don't have version issues with `progressbar`.
+**Note**: If I install one of those version suggestions, StableAudioSampler should work, but at the same time, it might make other packages not work.
