The face box

1A mini face

Open My First Face. The Tone box shows a small copy of its face under its ports. It's live: the knobs move and the pads light as the sound plays.

A mini face is only to look at. A drag on it moves the Patch, as on any box.

2Play it in place: the front panel

1. Choose the button on the right of the box's header. The box now shows its front panel, full size.
2. Turn a knob or press a pad, right there in the Patch.
3. Drag the box's bottom-right corner to make it bigger or smaller. The face lays itself out again, as a SwiftUI view does when its window resizes: grids, spacers and flexible frames take the new room, and a face with nothing flexible sits in the middle.
4. Double-click the corner to give it back its natural size. The header's button takes it back to its mini face.

3Open it

Double-click the box to go one level down. Inside, the face is one box called Face, with its own mini face. Each knob's binding is a wire from Face to the setting it turns.

Double-click Face to go inside it. There, a Content box starts the yellow chain of its views, as Inside a face shows.

4The sound's face

Full screen, a shared link and the Manual's live pictures show one module's face: the sound's face. A small yellow face badge marks its box. A module without views plays its settings as knobs.

By default it's the module called Face. A sound without one shows its first module with views. To choose another, right-click any box (touch and hold on a phone) and choose Show as Face.

In the code it's one line:

face = tone

A module inside another is written with a dot: face = tone.inner.
