# Dual Transport (BLE + AppleMIDI)

BLE for direct iOS/macOS connection, AppleMIDI for DAW integration over WiFi.
Elements send to both transports simultaneously via pipe routing.

Build with `CS_MIDI_BLE=ON CS_MIDI_APPLEMIDI=ON`.

> **Note:** See the [AppleMIDI example](06-applemidi.md) for a reliability
> caveat on the WiFi transport. BLE remains the more reliable option on
> macOS/iOS.
