Decent-Sampler Drums MCP Server

Configure global pitch and envelope controls for each drum type.

This tool will:

• Add per-drum pitch controls with customizable ranges
• Configure ADSR envelope settings for natural decay control
• Generate proper XML structure for global drum controls

Error Handling:

• Validates pitch range values (min/max must be valid numbers)
• Ensures envelope times are positive values
• Verifies curve values are within -100 to 100 range
• Returns detailed error messages for invalid configurations

Success Response: Returns XML structure containing:

• Global controls for each drum type
• MIDI CC mappings for real-time control
• Properly formatted parameter bindings

Configure round robin sample playback for a set of samples.

This tool will:

• Validate sequence positions
• Verify sample files exist
• Generate proper XML structure for round robin playback

Error Handling:

• Checks if sample files exist at specified paths
• Validates sequence positions are unique and sequential
• Ensures mode is one of: round_robin, random, true_random, always
• Returns specific error messages for missing files or invalid sequences

Success Response: Returns XML structure with:

• Configured playback mode
• Sample sequence assignments
• Proper group organization for round robin playback

Analyze WAV files to detect common issues in drum kit samples.

This tool checks for:

• Non-standard WAV headers that may cause playback issues
• Metadata inconsistencies that could affect multi-mic setups
• Sample rate and bit depth compatibility
• Channel configuration issues
• File size and format validation

Error Handling:

• Reports detailed header format issues
• Identifies metadata inconsistencies between related samples
• Flags potential playback compatibility problems
• Returns specific error messages for each issue type

Success Response: Returns detailed analysis including:

• WAV header information
• Sample metadata
• Potential compatibility issues
• Recommendations for fixes

IMPORTANT: Always use absolute paths (e.g., 'C:/Users/username/Documents/Samples/kick.wav') rather than relative paths.

Configure multi-mic routing with MIDI controls for drum samples.

This tool will:

• Set up individual volume controls for each mic position (close, OH L/R, room L/R)
• Route each mic to its own auxiliary output for DAW mixing
• Configure MIDI CC mappings for mic volumes
• Generate proper XML structure for DecentSampler

Error Handling:

• Validates mic position assignments
• Checks for duplicate MIDI CC assignments
• Ensures valid output routing targets
• Verifies bus indices are unique and valid
• Returns specific errors for routing conflicts

Success Response: Returns XML structure containing:

• Configured mic bus routing
• Volume control mappings
• MIDI CC assignments
• Complete routing matrix for all samples

Generate DecentSampler <groups> XML for drum kits.

This tool supports two configuration types:

BasicDrumKitConfig:

• For simple presets with minimal features
• No UI controls, effects, or routing
• Only supports basic sample mapping and optional velocity layers
• Recommended for straightforward drum kits

AdvancedDrumKitConfig:

• For complex setups combining multiple features
• Supports UI controls, effects, and routing
• Integrates with other tools (configure_drum_controls, configure_mic_routing, etc.)
• Use when you need advanced features like round robin or multi-mic setups

Best Practices:

• IMPORTANT: Always use absolute paths (e.g., 'C:/Users/username/Documents/Samples/kick.wav')
• Group all samples for a drum piece into a single group
• When using multiple mic positions, include them all in the same group
• Use velocity layers within a group to control dynamics

Error Handling:

• Validates all sample paths exist
• Checks for valid MIDI note numbers
• Ensures velocity layers don't overlap
• Verifies muting group configurations
• Returns specific errors for any invalid settings

Example Configurations:

1. Basic Configuration (simple drum kit): { "globalSettings": { "velocityLayers": [ { "low": 1, "high": 42, "name": "soft" }, { "low": 43, "high": 85, "name": "medium" }, { "low": 86, "high": 127, "name": "hard" } ] }, "drumPieces": [{ "name": "Kick", "rootNote": 36, "samples": [ {"path": "C:/Samples/Kick_Soft.wav"}, {"path": "C:/Samples/Kick_Medium.wav"}, {"path": "C:/Samples/Kick_Hard.wav"} ] }] }
2. Advanced Configuration (multi-mic kit with controls): { "globalSettings": { "velocityLayers": [ { "low": 1, "high": 127, "name": "full" } ], "drumControls": { "kick": { "pitch": { "default": 0, "min": -12, "max": 12 }, "envelope": { "attack": 0.001, "decay": 0.5, "sustain": 0, "release": 0.1 } } }, "micBuses": [ { "name": "Close Mic", "outputTarget": "MAIN_OUTPUT", "volume": { "default": 0, "midiCC": 20 } } ] }, "drumPieces": [{ "name": "Kick", "rootNote": 36, "samples": [ { "path": "C:/Samples/Kick_Close.wav", "micConfig": { "position": "close", "busIndex": 0 } } ], "muting": { "tags": ["kick"], "silencedByTags": [] } }] }

Success Response: Returns complete XML structure with:

• Organized sample groups
• Velocity layer mappings
• Muting group configurations
• All sample references and settings
• Advanced features when using AdvancedDrumKitConfig
