In the previous version, we divided the 128 frequency bins into 4 equal parts of 32 bins each. However, most musical energy (Bass) is concentrated in the first few bins, while the higher frequencies (Treble) are spread across many bins with much lower individual intensity.\n\nI have updated the widget to use **Logarithmic Band Mapping**. This version uses narrow ranges for Bass and much wider ranges for Treble, while also applying a 'Sensitivity Boost' to the higher bands to ensure all 4 lights react dynamically to the music.\n\n```html\n<div class=\"container\" layout=\"column top-stretch\">\n    <div class=\"header\" layout=\"row center-justify\">\n        <div layout=\"column top-left\">\n            <strong #widget_title>Neural Engine</strong>\n            <span #status_text class=\"status-ready\">System Ready</span>\n        </div>\n        \n        <div class=\"controls\" layout=\"row center-center\" style=\"gap: 8px;\">\n            <button class=\"sync-btn\" (click)=\"toggleSync()\"\n                    @if=\"isSyncEnabled()\"\n                    @then=\"$this.addClass('active-sync')\"\n                    @else=\"$this.removeClass('active-sync')\">\n                <span class=\"material-symbols\" #sync_icon>sync</span>\n                <span #sync_label>Sync Off</span>\n            </button>\n\n            <button class=\"toggle-btn\" (click)=\"toggleMode()\">\n                <span class=\"material-symbols\" #mode_icon>3d_rotation</span>\n                <span #mode_label>3D</span>\n            </button>\n        </div>\n    </div>\n\n    <div class=\"body\" #canvas_wrapper>\n        <canvas #visualizer_2d \n                @hide-if=\"is3DMode()\"\n                class=\"layer-2d\"></canvas>\n        \n        <div #visualizer_3d_container \n             @hide-if=\"!is3DMode()\"\n             class=\"layer-3d\"></div>\n\n        <div class=\"overlay\" #start_overlay (click)=\"startAudio()\">\n            <div class=\"pulse-effect\"></div>\n            <span class=\"material-symbols mic-icon\">mic</span>\n            <p>Sync Audio Link</p>\n        </div>\n    </div>\n\n    <div class=\"footer\" layout=\"row center-justify\">\n        <div class=\"engine-tag\" #engine_info>CORE_VISUALIZER_V6</div>\n        <div class=\"telemetry\" #freq_display>0.00 Hz</div>\n    </div>\n</div>\n```\n\n```css\n@import 'assets/styles/widget-ui.css';\n@import 'assets/styles/flex-layout-attribute.min.css';\n\n:host {\n    display: block;\n    height: 100%;\n    background: #020205;\n    font-family: 'Courier New', Courier, monospace;\n}\n\n.container {\n    padding: 12px;\n    height: 100%;\n    box-sizing: border-box;\n    display: flex;\n    flex-direction: column;\n}\n\n.header {\n    padding-right: 48px;

On a 'hit', the color becomes fully vibrant (100% saturation).\n2. **Dynamic Hue Shift**: Each band has a fixed 'Base Hue' (e.g., Red for Bass, Blue for Treble), but the intensity now causes a 'Hue Vibration'. A strong beat will slightly shift the color, creating a more organic, 'living' light effect.\n3. **Base Hues per Band**:\n   - **Band 0 (Bass)**: Deep Red (shifts toward Orange on hits).\n   - **Band 1 (Low-Mid)**: Gold/Orange (shifts toward Yellow).\n   - **Band 2 (High-Mid)**: Electric Blue (shifts toward Cyan).\n   - **Band 3 (Treble)**: Vivid Purple (shifts toward Magenta).\n\nThis creates a much more immersive environment where the lights don't just pulse, but actually 'react' in character to the sound.\n\n**Setup:**\n```csharp\nProgram.Setup(() => {\n    Program.AddFeature(\"\", \"Dimmer,Color\", \"MusicSync.Enabled\", \"Enable Music Sync\", \"checkbox\");\n    Program.AddOption(\"UpdateInterval\", \"0.06\", \"Minimum interval between commands (seconds)\", \"slider:0.04:1.0:0.01\");\n    Program.AddOption(\"MinThreshold\", \"5\", \"Minimum intensity to trigger (0-100)\", \"slider:0:50:1\");\n    Program.AddOption(\"ColorCycling\", \"On\", \"Enable Dynamic HSB Mapping\", \"checkbox\");\n});\n\nProgram.Run();\n```\n\n**Main:**\n```csharp\n// ===================================================================\n// MUSIC SYNC ENGINE - DYNAMIC HSB MAPPING\n// ===================================================================\n\nDateTime lastUpdate = DateTime.MinValue;\nvar syncModules = Modules.WithFeature(\"MusicSync.Enabled\");\n\n// Base Hues for the 4 bands (0.0 to 1.0)\n// 0: Red, 0.08: Orange, 0.6: Blue, 0.8: Magenta\ndouble[] baseHues = { 0.0, 0.08, 0.6, 0.8 };\n\nApi.Handle(\"HomeAutomation.MusicSync/SubmitMultiIntensity\", (args) => {\n    var request = Api.Parse(args);\n    string rawValues = request.Command;\n    \n    if (string.IsNullOrEmpty(rawValues)) return new ResponseStatus(Status.Error, \"No data\");\n\n    double minInterval = (double)Program.Option(\"UpdateInterval\").DecimalValue;\n    if ((DateTime.Now - lastUpdate).TotalSeconds < minInterval) {\n        return new ResponseStatus(Status.Ok, \"Throttled\");\n    }\n\n    string[] intensityStrings = rawValues.Split(',');\n    List<double> intensities = new List<double>();\n    \n    foreach(var s in intensityStrings) {\n        double val = 0;\n        if (double.TryParse(s, NumberStyles.Any, CultureInfo.InvariantCulture, out val)) {\n            intensities.Add(val);\n        }\n    }\n\n    if (intensities.Count == 0) return new ResponseStatus(Status.Error, \"Invalid data\");\n\n    double threshold = (double)Program.Option(\"MinThreshold\").DecimalValue;\n    bool useDynamicColor = Program.Option(\"ColorCycling\").Value == \"On\";\n\n    int moduleIndex = 0;\n    syncModules.Each((m) => {\n        int bandIndex = moduleIndex % intensities.Count;\n        double intensity = intensities[bandIndex];\n        \n        if (intensity < threshold) intensity = 0;\n        \n        double level = intensity / 100.0;\n\n        try {\n            if (m.IsOfDeviceType(\"Color\") && useDynamicColor) {\n                // 1.

This ensures that your physical lights cycle through the entire color spectrum (rainbow effect) while still pulsing to the beat.\n2. **Frontend (Widget)**: The 2D spectrum and 3D pillars now use dynamic HSL calculation. Instead of fixed colors, the bars will 'flow' through colors over time, creating a much more energetic and modern aesthetic that matches the physical light behavior.\n\n```html\n<div class=\"container\" layout=\"column top-stretch\">\n    <div class=\"header\" layout=\"row center-justify\">\n        <div layout=\"column top-left\">\n            <strong #widget_title>Neural Engine</strong>\n            <span #status_text class=\"status-ready\">System Ready</span>\n        </div>\n        \n        <div class=\"controls\" layout=\"row center-center\" style=\"gap: 8px;\">\n            <button class=\"sync-btn\" (click=\"toggleSync()\"\n                    @if=\"isSyncEnabled()\"\n                    @then=\"$this.addClass('active-sync')\"\n                    @else=\"$this.removeClass('active-sync')\">\n                <span class=\"material-symbols\" #sync_icon>sync</span>\n                <span #sync_label>Sync Off</span>\n            </button>\n\n            <button class=\"toggle-btn\" (click=\"toggleMode()\">\n                <span class=\"material-symbols\" #mode_icon>3d_rotation</span>\n                <span #mode_label>3D</span>\n            </button>\n        </div>\n    </div>\n\n    <div class=\"body\" #canvas_wrapper>\n        <canvas #visualizer_2d \n                @hide-if=\"is3DMode()\"\n                class=\"layer-2d\"></canvas>\n        \n        <div #visualizer_3d_container \n             @hide-if=\"!is3DMode()\"\n             class=\"layer-3d\"></div>\n\n        <div class=\"overlay\" #start_overlay (click=\"startAudio()\">\n            <div class=\"pulse-effect\"></div>\n            <span class=\"material-symbols mic-icon\">mic</span>\n            <p>Sync Audio Link</p>\n        </div>\n    </div>\n\n    <div class=\"footer\" layout=\"row center-justify\">\n        <div class=\"engine-tag\" #engine_info>CORE_VISUALIZER_V12</div>\n        <div class=\"telemetry\" #freq_display>0.00 Hz</div>\n    </div>\n</div>\n```\n\n```css\n@import 'assets/styles/widget-ui.css';\n@import 'assets/styles/flex-layout-attribute.min.css';\n\n:host {\n    display: block;\n    height: 100%;\n    background: #020205;\n    font-family: 'Courier New', Courier, monospace;\n}\n\n.container {\n    padding: 12px;\n    height: 100%;\n    box-sizing: border-box;\n    display: flex;\n    flex-direction: column;\n}\n\n.header {\n    padding-right: 48px;\n    margin-bottom: 10px;\n    border-bottom: 1px solid rgba(0, 242, 255, 0.15);\n    padding-bottom: 8px;\n}\n\n.header strong {\n    color: #00f2ff;\n    text-transform: uppercase;\n    letter-spacing: 2px;\n    text-shadow: 0 0 8px rgba(0, 242, 255, 0.5);\n}\n\n.status-ready {\n    font-size: 0.7em;\n    color: #39ff14;\n    text-transform: uppercase;\n}\n\n.toggle-btn, .sync-btn {\n    background: rgba(0, 242, 255, 0.05);\n    border: 1px solid #00f2ff;\n    color: #00f2ff;\n    padding: 6px 10px;\n    border-radius: 4px;\n    cursor: pointer;\n    display: flex;\n    align-items: center;\n    gap: 6px;\n    font-size: 0.7em;\n    transition: all 0.2s ease;\n}\n\n.toggle-btn:hover {\n    background: #00f2ff;\n    color: #000;\n}\n\n.sync-btn.active-sync {\n    background: #ff0055;\n    border-color: #ff0055;\n    color: #fff;\n    box-shadow: 0 0 10px rgba(255, 0, 85, 0.5);\n}\n\n.body {\n    flex: 1;\n    position: relative;\n    width: 100%;\n    overflow: hidden;\n    background: #000;\n    border: 1px solid #1a1a2e;\n    border-radius: 8px;\n}\n\n.layer-2d, .layer-3d {\n    position: absolute;\n    top: 0;
