# User Interface Overview

The **Ground Central** features an intuitive interface for setting up FX, creating MIDI maps, loading presets, and more. Here's a quick overview:

> Please bear in mind that some UI images in this document may be outdated and may not reflect the latest available firmware version.

### **Preset Loaded Screen**

If no **Satellite** is paired, you'll see the Preset Loaded view by default. From here, you can pair new **Satellites** or access the Settings Menu.

Once at least one **Satellite** is paired, you’ll see an editable version of the **Preset Loaded** screen. It displays information for each **Satellite**, including battery level, signal strength, and assigned functions.

From this screen, you can:

- Assign and manage audio FX
- Save your current preset
- Access the Settings Menu
- Bypass the audio signal

### **MIDI Configuration Screen**

From the Satellites Menu, you can access to MIDI Configuration. You can assign up to five MIDI messages across different channels, per **Satellite**. For each message, you can:

- Set values and MIDI channel.
- Adjust sensitivity, attack, and decay based on the chosen control input (Roll, Up/Down, Left/Right, Acceleration, etc.)

> When **Note On** is selected, you can enable *Arpeggio mode* to generate a sequence of notes within a defined range, from the root note to the end note. You can also choose from a variety of scales, including Major, Minor, Pentatonic Major, Pentatonic Minor, Ionian, Dorian, Phrygian, Lydian, Mixolydian, Aeolian, and Locrian.

From the Satellites Menu, you can access to the Sound Library. Constellation has a series of pre-loaded Sound samples that you can trigger with any of the tracking movements that the Satellite offers.

You can choose to trigger a Snare Drum sample with your Tilt down movement, adjusting threshold, sensibility, attack, and decay.
