# Getting Started

cs-midi is a standalone MIDI library for pico-sdk, extracted from [Control Surface](https://github.com/tttapa/Control-Surface). It provides BLE MIDI, Classic BT SPP MIDI, rotary encoders, buttons, potentiometers, LEDs, banks, and a flexible pipe-based routing system.

## What's included

- **BLE MIDI** via BTstack (pico-native, no Arduino)
- **Output elements**: NoteButton, CCRotaryEncoder, CCPotentiometer, and more
- **Input elements**: NoteValue, CCValue, PBValue, LEDs
- **Pipe routing**: bidirectional MIDI pipes with filter/transform support
- **Banks**: switch between multiple CC/note mappings
- **Custom hooks**: extend the library without modifying it
