You can even create astonishingly human‑sounding drum tracks and become inspired by thousands of loops from popular genres like EDM, Hip Hop, Indie, and more.

More sounds, more inspiration.
Plug in your USB keyboard and dive into the completely inspiring and expanded Sound Library, featuring electronic‑based music styles like EDM and Hip Hop. The built‑in set of instruments and loops gives you plenty of creative freedom.

The Touch Bar takes center stage.
The Touch Bar on MacBook Pro puts a range of instruments at your fingertips. Use Performance view to turn the Touch Bar into drum pads or a one-octave keyboard for playing and recording.

Plug it in. Tear it up.
Plug in your guitar and choose from a van-load of amps, cabinets, and stompboxes.

Design your dream bass rig.
Customize your bass tone just the way you want it. Mix and match vintage or modern amps and speaker cabinets. You can even choose and position different microphones to create your signature sound.

Drumroll please.
GarageBand features Drummer, a virtual session drummer that takes your direction and plays along with your song. Choose from 28 drummers and three percussionists in six genres.

Shape your sound. Quickly and easily.
Whenever you’re using a software instrument, amp, or effect, Smart Controls appear with the perfect set of knobs, buttons, and sliders. So you can shape your sound quickly with onscreen controls or by using the Touch Bar on MacBook Pro.

Look, Mom — no wires.
You can wirelessly control GarageBand right from your iPad with the Logic Remote app. Play any software instrument, shape your sound with Smart Controls, and even hit Stop, Start, and Record from across the room.

Each drummer has a signature kit that lets you produce a variety of groove and fill combinations. Use the intuitive controls to enable and disable individual sounds while you create a beat with kick, snare, cymbals, and all the cowbell you want. If you need a little inspiration, Drummer Loops gives you a diverse collection of prerecorded acoustic and electronic loops that can be easily customized and added to your song.

Powerful synths with shape‑shifting controls.

It's in the HTML

• Roles, states, and properties
• Basic keyboard accessibility

And that's important

First, there's the DOM

Accessibility APIs

Windows

• MSAA
• IAccessible2
• UI Automation

Inspecting the Accessibility APIs

Windows

• AViewer
• Accessibility Probe
• Inspect Objects (MS Windows SDK)

Mac OS

• Accessibility Inspector (Xcode)

Linux

• Accerciser

Demo: Mac Accessibility Inspector

Still, there's the DOM

Useful when:

• the API does not support certain information, or
• the information passed to the API is incomplete

Native vs. Custom Widgets

Example: Checkbox (1/3)

No keyboard access.

No role or state information.

Solution: WAI-ARIA

It's just attributes and values

• roles use @role, e.g.
• states and properties use @aria-*,
  e.g.

It's part of the HTML5 specification.

Landmark roles

• application
• banner
• complementary
• contentinfo
• form
• main
• navigation
• search

Document structure roles

• article
• columnheader
• definition
• directory
• document
• group
• heading
• img
• list
• listitem
• math
• note
• presentation
• region
• row
• rowheader
• separator
• toolbar

Native ARIA semantics

• header → “banner” role, if not a child of section or article
• nav → “navigation” role
• main → “main” role
• aside → “complementary” role
• footer → “contentinfo” role, if not a child of section or article

Standalone widget roles

• alert
• alertdialog
• button
• checkbox
• dialog
• gridcell

• menuitemradio
• option

• progressbar
• radio
• scrollbar
• slider
• spinbutton
• status
• tab
• tabpanel
• textbox
• timer
• tooltip
• treeitem

Composite widget roles

• combobox
• grid
• listbox
• menu
• menubar
• radiogroup
• tablist
• tree
• treegrid

Native ARIA semantics

• button → “button” role
• input type='checkbox → “checkbox” role
• input type='radio' → “radio” role

Overriding native HTML semantics

• list item button

States and properties

Widget attributes

• aria-autocomplete
• aria-checked (state)

• aria-pressed (state)
• aria-readonly
• aria-required
• aria-selected (state)

• aria-valuemax
• aria-valuemin

• aria-valuetext

Live region attributes

Drag-and-drop attributes

• aria-dropeffect
• aria-grabbed (state)

Relationship attributes

• aria-activedescendant
• aria-controls
• aria-describedby
• aria-flowto
• aria-labelledby
• aria-owns
• aria-posinset
• aria-setsize

Managing keyboard focus

• 
  Adds an element to the Tab order at its position in the source order.
• 
  Removes an element from the Tab order.
  Makes non-focusable elements programmatically focusable.
• (Avoid)
  Specifies an element's position following the default Tab order.

role='presentation'

Removes an element's default semantics.

Not on focusable elements

Don't do this!

It won't work anyway.

Example: Checkbox (1/3) revisited

No keyboard access.

No role or state information.

Example: Checkbox (2/3)

Add keyboard support

Still no role or state information.

Example: Checkbox (3/3)

Add role and state

2. add toggle for @aria-checked

Role and state provided.

Example: range slider (1/3)

input type='range'

Otherwise falls back to input type='text'.

Example: range slider (2/3)

Custom slider with JavaScript

Good news

Browser and screen reader support is improving all the time.

Good support for structural roles and many common widgets and attributes.

Not so good news

Still lots of variability in browser and screen reader support,
especially for complex widgets.

Due diligence

Do the research, as you do…

Rules of engagement

Rules of engagement

Using WAI-ARIA in HTML

First rule of ARIA use

Use native HTML elements and attributes as much as possible.

Second rule of ARIA use

Don't override native HTML semantics, unless absolutely necessary.

Thanks
