# MIDI Controller Mode

Constellation can transmit up to five simultaneous MIDI messages per **Satellite** via USB or the standard MIDI DIN-5 connector.

### macOS Setup \[Troubleshooting\]

If you're using macOS and **Constellation** isn't automatically recognized as a MIDI device after connecting via USB, make sure an external MIDI device is present in your MIDI Studio:

1. Open **Audio MIDI Setup** (Search "Audio MIDI Setup" in Spotlight).
2. Go to **Window** → **Show MIDI Studio**.
3. If no external MIDI device is listed, click the **plus (+)** button to create one.

Once your external MIDI device is created, you can configure its transmit and receive channels and assign it a custom name. This device will act as the communication bridge between **Constellation** and your virtual environment / MIDI instrument.

### Windows Setup

Constellation should be recognized as a MIDI interface automatically in Windows 10 and 11 - No drivers required.
