• Compound Map Screen - fixed bug that prevented very wide maps from being displayed in editing mode, added "Touch Select" option to prevent touches from changing selection, updated help text • PixelPusher discovery using more efficient sockets • PixelPusher - "Undiscover Duration" now working properly • DMX - in the "Channel Values" string, you can now specify multiple R, G, B, and W characters, sending the red, green, blue, and white values to multiple DMX channels. • Virtual Strips text now allows comments after '#' character • Videos and Images in the root level of the Documents Folder are now displayed in a group called "Documents Folder", rather than "Unknown"

• fixed some issues around the "Undiscover" feature in the LED Setup screen. • In the "DMX" section of the LED Setup screen, you can now specify that the RGBW data be sent to multiple bytes in the DMX channel stream. This is useful for DMX floodlights and other non-LED-strip DMX devices.

• Fixed to OSC control of current scene • Fixed issue that sometimes caused a pictures scene that uses another scene as a picture to lose track of the embedded scene. • Tweaks to the Edit Map File screen. • DDP controllers can now have any number of outputs.

• A problem that caused purchases to not be remembered sometimes has been fixed. • The LED Setup Screen allows you to specify when PixelPusher controllers are un-discovered. • The Virtual Strips Screen now displays correctly when the device is in Dark Mode. • MIDI control of global brightness and speed now works properly. • When a Scene name contained a '/' character, it couldn't be used in another scene. This has been fixed. • Rendering large images with tiling is now faster. • When Mapping Preview is enabled in Scene Editing View mode, touches in the preview area are now used to edit the Scene.

• In the Scene Grid and Track Grid Display Modes, any scene or track set to be "skipped" in the normal play order are not displayed. • There are several fixes and improvements to the Edit Map File screen. • Virtual Strips text now allows there to be trailing commas • In the LED Setup screen, the icon displayed for each PixelPusher controller now displays the "controller ordinal" number specified in the PixelPusher controller. • Sometimes when there was an error sending data to a PixelPusher controller, and there was more than one controller, sending to the controllers and the preview would hang until the program was restarted. This has been fixed. • When the program went to the background and then the set of connected PixelPusher controllers changed, upon returning to the foreground, the old controllers would mistakenly be assumed to still be connected. This has been fixed.

• In a Pictures or Strips Scene, when Hue is modulated with the Wheel waveform, it is now possible specify Acceleration. • In a Pictures Scene, when Rotation is modulated with the Wheel waveform, it is now possible specify Acceleration. • A rare startup crash in the In-App Purchase code has been fixed. • The "OSC Output..." Edit Popup item in the Scene List no longer crashes. • XCode 15 caused a bug that would prevent the use of a Multicast IP address with an LED Controller. This has been fixed.

• Full support for Dark Mode • Better layout on iPhones X or later • Re-vamped Edit Map File and Scan Map File screens • There are new options for setting the start time of a Scene in Track editing • No longer does double-tapping a Scene set its start time in a Track. There is now a button for this. • Better handling of when images/videos move to different folders • Tapping the current Scene re-starts it without crossfade • Fixed bugs in Virtual Strips Screen's "sequence" UI • One instance of LED Lab can now control the current Scene of another (on a different device) • In Waveforms, "DMX" has been changed to "ArtNet" • Rectangular tiles now have no gaps between them • In the Upgrades screen, the upgrades are once again in order • Since Xcode no longer supports iOS 9.x, the minimum supported iOS version is now 10.0

• When OSC external control was turned on, Apple's Bonjour service would consume the LAN's bandwidth and cause jittery display, particularly on WiFi. This has been fixed. (Bonjour is no longer used.) • Updated help strings for External Control Screen and Embedding Options Screen • Improved Logic for when Scene thumbnails are created • Removed Crashlytics framework

• When new images and videos are added to LED Lab's documents folder, they now automatically appear in the UI. • The default size of the bitmap used to render embedded Scenes is now half of what it was, leading to much faster rendering. • The Embedding Options Screen is a lot clearer. • The Embedding Options Screen for Strips Scenes allows the number of strips to be fixed. This is great for embedding Strips Scenes that need small numbers of strips for the desired effect. • When a Scene has OSC Out data, tapping the "OSC" in its list cell now opens the OSC Out screen for the Scene. • After "New Embedding Scene" and making a change, the Revert button would remove the original embedded Scene. This has been fixed. • Revert and Redo no longer display their result with a transition. It appears immediately. • When an image or video is missing from the documents folder, a warning message is now only displayed when the scene that refers it becomes current. • Fixed a bug that sometimes caused the start time of a Video Picture to be ignored when the rewind button was tapped. • Tweaked some colors in the UI to look better in Dark Mode.

• When the current track is tapped, it is no longer re-started. • When the Track "Auto-Show Scenes" setting is turned on, the current Track's scenes are shown and all others hidden. • When a Track's scenes are manually shown or hidden, "Auto-Show Scenes" is turned off. • Flicking to scroll the Track Editing scene list sometimes would result in a scene being dragged. This has been fixed. • Some audio hardware causes a large delay when starting up. This would sometimes cause the audio of a Track to lag behind its scenes. Now, the audio system is kept running so that these delays are not an issue. • When the Track "Gap" was non-zero, the next Track's audio would be started twice. This would result in an audio glitch and cause the audio of a Track to lag behind its scenes. This has been fixed.

• Fixed bug that sometimes caused crash when selecting Waveform type.

• Importing videos from the Camera Roll works again • Finding LED Lab with Touch OSC or other OSC client app works again • Global brightness can now be controlled by MIDI, ArtNet, or OSC • Global speed can now be controlled by MIDI, ArtNet, or OSC

Fixed some rare crash bugs.

• Zooming in and out in the New File and Edit Map screens is improved • Zooming in and out in the Compound Map screen is now possible. • When Maps are edited, the UI on the screen is now displayed on the LEDs too. • New command to create a Pictures Scene that uses another Scene as its first Picture. • New ways of handling RGBW pixels/strips, in the DMX section of the LED Setup screen.

• Mapping has been thoroughly re-worked - faster, higher quality, more options • You can now make a Compound Map, a map which is made from any number of Map Files, each positioned, sized, flipped, and rotated individually. This is very useful for A) displaying the same image on both sides of a vehicle B) stitching together a number of optically-created maps made for different sections of an LED display that's too large to map in a single Map File C) combining maps made from all sides of a 3D display • The Edit Map screen now allows you to add and delete new strips and LEDs freely. You can link a sequence of LEDs so that they always stay in a straight line as you move the ends around. Basically, you can now create a Map by hand! • Cleaned up the Strips/Picture paradigm in the Mapping Setup Screen. There is now only Virtual Strips and the Map. You can now use Virtual Strips with Rectangular Panels maps. • There are more options when specifying simple horizontal or vertical mapping. • You've always been able to use a Strips Scene in a Picture in a Pictures Scene. Now you can embed Pictures Scenes as well, to any level of nesting. This is dramatically powerful, particularly when used with Tiling. • When driving ArtNet or sACN controllers, you can now use UDP broadcasting to send all data to all controllers, in the style of traditional DMX setups. • Fixed two bugs introduced in version 2.0

• Fixed bug in saving Rectangular Panels parameters • While editing tracks, you can now display just the songs in a specified Playlist.

• Custom Virtual Strips - excellent for mapping arrangements of LEDs that are in straight lines but irregular. • Mapping Options - you can now rotate (with animation) and skew the mapping. • Scene Options Screen - allows detailed editing of duration, speed scale, title, and other properties of a Scene • Speed Scale - speed scale factors can be applied to each Scene, inside and outside a Track • OSC Out - many new features and capabilities • Map File Screen - improved UI, better editing capabilities

• A bug in the scene/track Cut command has been fixed (important). • When the app first runs, it saves the LED Setup and Mapping Setup parameters separately from any show. This allowedA the elimination of many warning messages. • A couple of subtle bugs involving scene duplication have been fixed. • Many subtle improvements have been made to the Tracks UI.

This is a major update! • The play, previous, and next buttons are now gathered into an orange "transport bar" along with restart and pause buttons. • One can now select more than one Track, Scene, or Picture at a time and perform cut/copy/paste/replace/duplicate operations on them all at once. • Revert/redo is now in its own button so you can see immediately if you've made changes. • The Display Popup now contains a "Lock" item which hides much of the app's UI. This is great when you want the public to be able to choose Scenes but not edit your Show. • When Autosave is off, the app still remembers the current Scene. • In the Pictures editing UI, the Picture List now shows a thumbnail of each picture with its Coloring attributes applied. • Tracks are now smarter how they find the Scenes they refer to. When a Scene’s name is changed, every Track that refers to it is changed as well. If a Track's Scene can't be found, the name of the un-found Scene is shown for easy repair. • ArtNet and sACN LED controllers no longer have a limit of 682 LEDs per output. • The Mapping Setup screen has more options for setting the "LED BItmap" size. • A bug has been fixed that sometimes caused a crash on old (32-bit) iOS devices when the LED Setup was not yet set.

• Scene invocation can now be controlled by a single DMX channel (External Control). • A bug in controlling Scenes via OSC messages has been fixed • PixelPusher controllers no longer have their global brightness reset when they are discovered.

• You can now use LED Lab with sACN controllers • When using ArtNet or sACN controllers, you can now configure how universe and channel numbers are generated. • The Rectangular Panels mapping has been improved, eg: You can now use panels with vertical rows of LEDs. • Control of the LED Bitmap SIze has been improved.

• ArtNet data can now be sent starting at any universe number • ArtNet data can now be send in a specified channel range • LED Lab now maps “outputs” and “pixels” to ArtNet “channels” with much more flexibility. You can now drive a series of DMX devices as if they were an LED strip. • When a PixelPusher becomes temporarily unreachable, LED Lab now waits a while before considering it "gone" and re-mapping pixels accordingly. • A few little bug fixes.
