# Tap a printed controller

Print a stream deck, keyboard or DJ controller, lay it where your webcam sees it, and tap it.
Print a sheet, lay it on your desk, the floor or a shelf where your webcam sees it, and tap a pad. Aden sees the tap and does what that pad is set to do. The picture never leaves your computer.

* **Stream deck**: fifteen pads. Each one presses a shortcut, plays or skips music, changes the volume, opens a link or an app, or sends MIDI.
* **Keys**: two octaves, C3 to C5, that play MIDI notes in your music app.
* **DJ**: two decks with four hot cues, sync, cue and play, and a crossfader, all MIDI for your DJ app to learn.

Several sheets can lie in view at once.

## Set one up [#set-one-up]

1. Press **⌘K** and search **Paper controls**, or **New paper stream deck**, **New paper keyboard** or **New paper DJ controller**.
2. Click a pad on the sheet to choose what it does. Search the list, or pick **Shortcut** and press the keys.
3. Choose **Print** and print at actual size (100%).
4. Lay the sheet flat with all four corners in view and press **Start**.

Use the settings button to name the sheet, switch between Letter and A4, pick the MIDI output or delete the sheet.

## Send MIDI [#send-midi]

MIDI pads send to the output you pick in the sheet's settings. On a Mac, turn on the IAC Driver in **Audio MIDI Setup** and pick its bus. Your music and DJ apps can listen to it. A connected MIDI device works too.

## Allow shortcuts on a Mac [#allow-shortcuts-on-a-mac]

Shortcut and media pads need Aden under **System Settings → Privacy & Security → Accessibility**. The window asks with **Allow**.
