Surface Builder is a versatile tool developed by Limelight Software, designed for creating custom control surfaces that send MIDI data to audio components. This program simplifies remote control tasks by allowing users to build surfaces of various sizes, adding buttons, knobs, faders, and more, and configuring them to generate the desired MIDI output. With Surface Builder, users can send note on/off, controller change, program change values, emulate modulation wheel and pitch bend data, and even send bulk MIDI data with a single key press. The ability to create interfaces spanning multiple scenes and link between them enables the construction of complex and interactive designs.

This feature-rich tool supports a wide range of object types such as buttons, switches, knobs, sliders, keyboards, and more, allowing for extensive customization. Users can drag and drop audio files onto buttons to create clip players, attach knobs to control volume and pan, and even add filter knobs for further audio manipulation. Additionally, Surface Builder offers multi-scene support, allowing for intricate designs, along with multi-level undo/redo functionality and a MIDI monitor for precise control over MIDI data flow.
