You can also just choose `sonar_euler` or `sonar_euler_ancestral` from the normal samplers list (will use the default settings). I personally recommend using the custom sampler approach and the ancestral version.

## Nodes
1. `SamplerSonarEuler` — Custom sampler node that combines Euler sampling and momentum and optionally guidance. A bit boring compared to the ancestral version but it has predictability going for it.
2. `SamplerSonarEulerAncestral` — Ancestral version of the above. Same features, just with ancestral Euler.
3. `SonarGuidanceConfig` — You can optionally plug this into the Sonar sampler nodes. See the [Guidance](#guidance) section below.
4. `NoisyLatentLike` — If you give it a latent (or latent batch) it'll return a noisy latent of the same shape. Allows specifying all the custom noise types except `brownian` which has some special requirements. Provided just because the noise generation functions are conveniently available. You can also use this as a reference latent with `SonarGuidanceConfig` node and depending on the strength it can act like variation seed (you'd change the seed in the `NoisyLatentLike` node). *Note*: The seed stuff may or may not work correctly.

6. `SamplerSonarDPMPPSDE` — This one is extra experimental but it is an attempt to add moment and guidance to the DPM++ SDE sampler. It may not work correctly but you can sample stuff with it and get interesting results.
