MIDI Lab is a comprehensive tool designed to handle any MIDI processing setup, suitable for both studio and live environments. It enables users to connect all MIDI hardware and control it from a single interface, operating as a standalone application or as a VST3/AU plugin. This flexibility allows MIDI Lab to host other VST3/AU plugins, expanding its capabilities for audio and MIDI processing within a unified platform.

Featuring a modern modular drag-and-drop interface, MIDI Lab provides extensive routing options for MIDI and audio signals, alongside a variety of built-in processing blocks such as mergers, splitters, filters, and controllers. Users can create and manage multiple presets within a single project, utilize macro blocks for reusable structures, and take advantage of scripting and expression blocks for advanced customization. Additionally, integrated tools like a MIDI file player, on-screen keyboard, velocity modifiers, and a clock generator enhance control and creativity.

MIDI Lab also supports automation through a Web API and Lua scripting, allowing remote control and custom GUI panel creation. Its interface supports tabs for plugin and block GUIs, customizable controller surfaces, and color-coded wiring for clarity. With ongoing development including a manual, iOS edition, and asset management features, MIDI Lab continually evolves to meet the complex needs of MIDI management and processing across various workflows.
