New • Deep Space, a new visualization in the Visualization Pack: a flight past ringed planets, asteroid fields and nebulae that take on the colors of the album that is playing. Improved • The Visuals menu is redesigned. Set the speed and the colors, and see the whole song laid out in a chart. • The playback buttons now sit beside the other controls. • Visualizations are smoother and sharper on Apple TV 4K (1st generation). Fixed • A judder every few seconds while following music playing on another device.

New • Visualizations now follow the music itself, not just its tempo. While Theatrium Live plays Spotify on your Apple TV (Spotify Premium required), every visualization rides the song's energy, lifting through builds and drops and easing off in breakdowns, while keeping its own design. • One accent on the first beat of each bar and a lighter one on the third. Nothing pulses on every beat any more. • Aurora and Butterfly now follow the music. Before, they stayed slow and flat. The fractals, Line Ribbons, Ocean, Fire and Black Oil also move further in busy passages and less far in calm ones. • Mirrorball turns faster on louder sound. The iPod in Click Wheel tilts and sways with the music on a wash of the cover's colors, and the CD, the cassette and the album-color drift follow the music too. • Bar Wall, Bar Halo and Ribbon keep their own shapes and grow and shrink with the music. Logo Bars, Bar Wall, Bar Halo and Ribbon can be set to Equalizer or Conductor in Settings. • The info panel in the visualizer has a new "Music and visuals" chart that plots Energy and Visual speed through the song. Changed • Motion speed now starts at In Time, which is as fast as Double Time used to be. If you had chosen a speed, it moves one step so your visuals look as they did. Fixed • Visuals that stopped or crawled while a song was playing. After certain song changes Theatrium Live treated the song as paused, so Mandala Zoom crept along and the CD stopped turning until the next song. • Mandala Zoom no longer stutters or jumps to a different ring when the pace changes, and Black Oil no longer lurches when the music gets louder or quieter. • A new visualization no longer jumps at the end of a crossfade. Known issues • The music-following motion works while Theatrium Live plays Spotify itself. Apple Music, Sonos and Last.fm keep to the song's tempo, as before. • On tvOS 27, Apple Music sometimes withholds the track name partway through a song. Theatrium Live shows "Loading track details…" until tvOS sends it, usually at the next track.

Spotify now plays straight to Theatrium Live, and the visualizations keep up with the music. New • Spotify: choose Theatrium Live in the Spotify app's device list and the music plays on this Apple TV, with album art, visualizations and light sync following along. Spotify Premium is required. Turn it on in Settings > Now Playing. Changed • Visualizations move with every beat instead of every second one, and faster songs are no longer slowed to half speed. If you chose a Motion speed earlier, it is kept; Double Time is now the default. • Mandala Zoom has a calmer center, richer rings and a slow breath that follows the song. Known issues • On tvOS 27, Apple Music sometimes withholds the track name partway through a song. Theatrium Live shows "Loading track details…" until tvOS sends it, usually at the next track.

Two new visualizations, a reworked Butterfly, and calmer, smoother fractals. New • Black Oil: glossy black oil that flows at the pace of the song. • Mandala Zoom: your album cover mirrored into a mandala that opens slowly and endlessly. With Reduce Motion on, it slows right down. • Both belong to the Visualization Pack. If you chose your own set of visualizations earlier, turn them on in Settings. Changed • Butterfly is now a flight of butterflies at different depths. • The fractal visualizations (Fractal Spiral, Burning Ship, Newton, Phoenix and Julia Morph) sit on a dark wash of the album's two colors and move with the song without flashing. They are sharper on the 2017 Apple TV. • The Mirrorball, Compact Disc, Mixtape and Click Wheel sit in a darker room. • Motion speed in Settings is now Half Time, In Time or Double Time. The visuals always keep time with the song. Fixed • Click Wheel now shows the real cover when it arrives late, instead of keeping a placeholder. Known issues • On tvOS 27, Apple Music sometimes withholds the track name partway through a song. Live shows "Loading track details…" until tvOS sends it, usually at the next track.

Steadier Apple Music on tvOS 27, and colours that follow the cover more closely. Fixed • Apple Music on tvOS 27: moving between screens no longer blanks the track for a moment. When tvOS reports that music is playing but has not yet passed the track over, Live now shows "Loading track details…" instead of an empty screen. • The background and your lights now take their colours from the whole cover, so they match the sleeve more closely. A green and brown cover no longer comes back blue and yellow. • One slow or unresponsive light no longer holds up colour changes for the rest of the room. Changed • Visual Styles opens as a compact panel, so the visual keeps playing behind it. • On new installs, each visual stays for the whole song instead of changing every 30 seconds. If you have already chosen a setting, it is kept. Known issue • On tvOS 27, Apple Music sometimes withholds the track name partway through a song. Live shows "Loading track details…" until tvOS sends it, usually at the next track.

Theatrium Live is now free to download, with one visualization included and the full collection available as a single purchase. New • Try it before you buy. Theatrium Live now includes Aurora at no charge, so you can confirm that your music source connects, the album art appears and your Apple Home lights follow along. • The Visualization Pack unlocks all 30 visualizations and every named color palette. It is a one-time purchase with no subscription, and it supports Family Sharing. • If you already use Theatrium Live, nothing is taken away. You keep every visualization and color palette at no cost. Still to come • The visuals take a few seconds to reach full speed after you start them. • Moving around the pop-up menus is still a little slow on the 2017 Apple TV.

Faster, smoother visuals — and a big difference on older Apple TVs. New • The visualiser runs considerably faster on every Apple TV. The improvement is largest on the 2017 model, where several styles were previously running at a fraction of their proper speed. • Bringing up the on-screen controls no longer slows the visuals down while they are showing. • The control panels have a cleaner, higher-contrast look that stays readable over bright album art. Still to come • The visuals take a few seconds to reach full speed after you start them. • Moving around the pop-up menus is still a little slow on the 2017 Apple TV.

New • Visuals now move in time with the music. Every visualisation locks to the song's tempo instead of running near it, so what's on screen and what you're hearing line up. If you preferred the old motion, turn it off under Settings, Visualizations, Motion speed. • Settings now explains what Last.fm is for: it's a free account, and it's how Theatrium follows along when you're playing through Spotify, or through Apple Music without a subscription. There's a step-by-step guide at theatrium.info. • Your Last.fm username is now saved deliberately, with a Save button, and shown back to you afterwards with a Change button to edit it. • Settings shows the app version, bottom left. Fixed • Apple Music could fail to launch on some Apple IDs. Fixed. • The two colours behind the album art no longer blend into a third colour through the middle. They now hand off cleanly, and the whole picture is smoother, brighter and reaches the edges of the screen. • In Last.fm mode, album art was missing entirely for any track Last.fm has no cover for, which is most of them these days. Theatrium now finds the artwork itself. • Last.fm could also show the previous album's cover on a run of tracks it had no artwork for, so you'd see one album's cover labelled as another. • The app icon and top shelf artwork now use the real Theatrium logo. • Song and artist names, and the label naming each button, stay readable against the brighter background. • When the controls fade and you pick the remote up again, you're returned to the button you were last on, including the playback controls.
