Decent Sampler Drums MCP Server
A Model Context Protocol server for generating Decent Sampler drum kit configurations.
This TypeScript-based MCP server provides specialized tools and prompts for creating DecentSampler drum kit presets, including WAV file analysis and XML generation.
Demo Video
Warning: Creating complex presets may end up exceeding Claude Desktop's maximum message length. We are still working on streamlining this tool to work around this limitation. If you are creating simple presets without a lot of mics or other variations, the xml file should be small enough for Claude to write to a file.
Features
- WAV file analysis and validation
- Global pitch and envelope controls
- Multi-mic routing with MIDI controls
- Round robin sample playback
- Flexible velocity layer handling
- Muting group support
- Auxiliary output routing

Usage Guidelines
When using this MCP server to generate simple presets, you should always reference the simple_preset_guidelines prompt.
For more complex presets (including sections such as buses, effects, etc.), reference the advanced_preset_guidelines prompt. Note that creating complex presets with a large number of samples can still be unstable and may exceed Claude Desktop's maximum message length.
Both prompts will ask you to provide a samplesDirectory argument - this should be the absolute path to your drum samples folder (e.g., "C:/Users/username/Documents/DrumSamples"). The prompt will then automatically use this directory in all examples and configurations, making it easier to follow along with the correct paths for your system.
