<!-- SECTION: Summary -->
## What is Surface Builder?

Surface Builder is a MIDI control surface creation tool that allows users to design custom interfaces with buttons, knobs, and faders to remotely control audio components. It supports bi-directional MIDI communication, enabling users to trigger interface elements or process MIDI and audio data through plugin integration. The app is notable for its ability to link multiple scenes for complex, large-scale interface management.

## Key Features

- **Custom MIDI Mapping**: Users can configure buttons, knobs, and faders to send note on/off, controller change, program change, modulation wheel, and pitch bend data.
- **Bi-directional MIDI Support**: The interface can both transmit MIDI data to external hardware and receive incoming MIDI data to trigger or control on-screen elements.
- **Multi-Scene Architecture**: The tool allows for the construction of complex interfaces that span multiple scenes with linking capabilities for advanced control workflows.
- **Flexible Plugin Integration**: Surface Builder functions as either a pure MIDI plugin for data processing or as an instrument plugin for audio signal routing.
