Release Notes Welcome to MultiTrack 5! This update includes a huge number of features: AUv3 support for effects/instruments/generators with 2 window sizes, and presets support. MP3 export using Lame, with command line in Settings.app FFT with 7 coefficient Blackman Harris window in Parametric EQ screen, with decade lines. Complete UI overhaul, with better visibility, highlighting buttons, and dynamic resizing. Support for zooming tracks vertically. Track Header controls are resized and centered on the fly. VU Meters add segements and resize dynamically. Support for Slide Over / Split View on iPad (iOS 11 or better) Drag and drop from other apps / Files app. Drop multiple audio files directly onto tracks! With Snap Helpers while dragging. Regions/Tracks will be created if necessary, multiple dropped audio files line up vertically. Support for portrait mode on iPhone with up to 15 tracks visible simultaneously on iPhone in portrait, 22 on iPad, 24 on iPad Pro. Support for Emojis on track, song, audio, region, and folder names, in color. Reworked Song Menu, with folders, new icons for zips and audio files, animations, MultiTrack projects are now (.mtdaw) packages. Ability to drag audio/projects/folders and drop onto other folders, or hover over the folder to traverse into that folder, or hover over the Back button to traverse up the hierarchy, with animations. Ability to preview audio files from the song menu (opens shared browser with play/import buttons) WiFi web server reworked to look more like the song menu with better resizing. Ability to traverse folders from web interface. Added 'Springiness' to track scrolling, this solves the bug of not being able to adjust the start handle of a region at zero. Now, edit the region as normal, use one finger to pull the window right and another finger to access the region start handle. Added AU/IAA effects icons to tracks, these are untappable and indicate the current effects on the track. They mimic the AU/IAA effects panel and rearrange when effects are rearranged, with animations. This makes it easy to see the status of all your plugins at once, with loading indicators and error overlays. AU/IAA effects panel now has 'No-Clip' unity gain control with VU Meter. If a plugin is clipping, turn this control down. The signal will be automatically boosted by the inverse amount after the plugin return. 'Follow' menu option added, now the automatic following of the playhead can be disabled. Follow is now slightly more aggressive and will follow even when looping. Better CPU usage when nothing is happening onscreen. Display of Beats/Time/Samples is now an optimized smearing number renderer (with glow). Song Menu remembers all song / audio / folder icon positions, and watches the current directory for changes in case a file is dropped from iTunes File Sharing, WiFi server or Drag&Drop. And MORE... 5.0.3 Bugfixes: AU/IAA compatibility fixes 5.0.2 Bugfixes: iOS 13 compatibility updates. Fix: Chipmunk bug on frozen mono tracks without effects on mixdown.

Fix: Projects over 16 tracks were hearing the underlying audio track when recording on a track. Fix: Better compatibility with AU/IAA plugins. 5.0.1 Bugfixes: Fixed song menu subicons for delete(X), zip, and rename box on 3x devices. Removed Bluetooth Low Energy, all bluetooth must now use A2DP due to poor sound quality. Set 'showsCloudItems' to NO in Music browser, music must be downloaded using the Music app before import. Fixed touch offset when dragging items and hovering over the Back button in song menu for devices with safety margins. Fixed placement of Input selector and AU/IAA effects panel and resized accordingly when rotating device. Fixed dynamic bubble placement for knob helpers. Fixed listbox content staying open when resized, content must close when resizing.
