    📟 Welcome to MD_NODES

    Strap in, traveler. This isn't just another GitHub repo—it's a wormhole into raw, modular creativity with ComfyUI at its freaky finest.

    Brought to you by a confederation of node-smiths, mod wizards, and digital dropouts, this is where unhinged meets unfiltered. Whether you're forging dreamscapes from the void or just want to vibe with your VAE, this is your personal BBS of brilliance.

    Packaged with ASCII-flavored love, open-source chaos, and a healthy disregard for conventional sanity.

    🎯 Universal Toolkit: While MD_Nodes began with a focus on audio generation (Ace-Step), most nodes are now universal tools that work with any diffusion model—Stable Diffusion, SDXL, Flux, video models, and beyond. Advanced sampling, scheduling, and guidance nodes are model-agnostic.

    🔥 Node Collection

    🎨 Wildcards & Prompt Engineering

    MD_WILDCARD_PROMPT_BUILDER ⭐

    The ultimate multi-mode prompt generation node. Far more than a simple text box, this is a seed-controlled prompt engine. It supports massive wildcard expansion, dynamic list choices, and robust string manipulation to keep your generations fresh yet controllable.

    🕹️ Advanced Sampling & Schedulers

    PINGPONG_SAMPLER (Lite+ & FBG Variants)

    Advanced ancestral sampler with sophisticated noise control. While originally optimized for Ace-Step audio, this is a powerful universal sampler suitable for any diffusion model (Stable Diffusion, SDXL, Flux, etc.).

    • v1.5.0 Update: Adds Res 2 (Restart) logic for iterative error correction with 5 restart modes.
    • Features: FBG dynamic Feedback Guidance, Noise Behavior presets, strength/coherence control, advanced blend modes, and NaN recovery.

    📖 Read the Manual

    HYBRID_SIGMA_SCHEDULER

    Universal precision noise scheduling. The ultimate sigma/noise scheduler.

    • Features: 14+ modes (Karras, Poly, AYS, Beta, Exponential, Bong Tangent), auto-detects model sigmas, supports slicing, visual plots, and comparison.
    • Utilities Included:
      • SigmaSmooth: Smoothes step transitions.
      • SigmaConcatenate: Joins different schedules together.

    📖 Read the Manual

    NOISEDECAY_SCHEDULER (Advanced)

    Universal custom decay curves. Generate sophisticated decay curves (polynomial, sigmoidal, gaussian, exponential) with start/end values, inversion, and smoothing.

    🧭 Universal Guidance & Control

    APG_GUIDER_FORKED

    Universal adaptive gradient guidance. Enhanced Adaptive Projected Gradient guidance that works with any diffusion model. Schedule APG scale, CFG, and momentum via YAML based on sigma. Surgical latent steering with minimal artifacts.

    MD_APPLY_TPG (Token Perturbation Guidance) 🆕

    Controlled chaos. Applies Token Perturbation Guidance by patching the model's Self-Attention mechanism. Breaks repetitive patterns and improves prompt adherence without high CFG burn.

    🎚️ Noise & Latent Generation

    MD_CUSTOM_NOISE_GENERATOR 🆕

    Beyond Gaussian. Generates advanced noise patterns for use with custom samplers.

    • Algorithms: Perlin, Voronoi (Worley), Collatz Orbit (Fractal), Wavelet, Pyramid, Pink Noise, and more.

    MD_MULTI_NOISE_BLENDER (5-Layer) 🆕

    Sonic alchemy for images. Mixes up to 5 different noise sources using advanced blend modes (Add, Multiply, Screen, Overlay, Difference) to create complex initial noise states. Inspired by the Sonar suite.

    MD_EMPTY_LATENT_RATIO_SELECTOR 🆕

    Perfect aspect ratios. Generates empty latents based on strict ratios (16:9, 21:9, etc.) and target megapixels. Auto-calculates exact dimensions divisible by 8 for SDXL/Flux compatibility. Includes orientation toggle.

    ⚡ Optimization

    MD_OPTIMIZER_SELECTOR 🆕

    Crash-proof training config. A safety factory for PyTorch Optimizers.

    • Features: Selects Prodigy, Lion, or AdamW.
    • Safety: Automatically detects if prodigyopt or bitsandbytes are missing and falls back to standard AdamW instead of crashing your workflow.
    • VRAM: Auto-enables 8-bit optimizers if available.

    🎵 Audio Processing

    MASTERING_CHAIN_NODE (Full & Modular)

    Make your audio thicc. Pro-grade mastering suite.

    • Modular Nodes: MD_Mastering_Gain, MD_Mastering_EQ, MD_Mastering_Compressor (Multiband), MD_Mastering_Limiter.
    • Features: True stereo multiband compression, surgical EQ, transparent limiting.

    AUDIO_AUTO_MASTER_PRO

    Iterative mastering magic. Automatically analyzes and processes audio to hit target LUFS and spectral profile using 3-band compression and stereo widening.

    AUDIO_AUTO_EQ

    One-click audio shaping. Analyzes audio spectrum and applies multi-band EQ based on 18+ target profiles (Vocal Clarity, Podcast, ASMR, etc.).

    ADVANCED_AUDIO_PREVIEW_AND_SAVE (AAPS)

    Hear it before you overthink it. Professional export: MP3/FLAC/OPUS, normalization (Peak/RMS/LUFS), fades, waveform/spectrogram preview, and metadata.

    ⚡ ACE T5 Audio Suite

    ACE_T5_CONDITIONING

    The main event. Intelligently blends T5 & CLIP embeddings for Ace-Step. Includes ACE_T5_CONDITIONING_SCHEDULED and ACE_T5_CONDITIONING_ANALYZER.
