Release Notes This update provides the following corrections and improvements: • Substantial app launch time improvement. • Fixes noise at beginning of new notes that happened under rare situations. • Fixes crash on certain MIDI messages (stand-alone app and Audio Unit). • Audiobus: Fixes connection problem with Audiobus on iOS 14 and higher (see NOTE below).¹ • Audiobus: If session is restored from Audiobus, don’t ask the same question dialog again whether IAA MIDI or IAA MIDI + CoreMIDI shall be used. • IAP downloads: Fixes active download from being interrupted under certain conditions if app was sent into background. • IAP downloads: Fixes active download being restarted under certain conditions after user requested to pause the download. • IAP downloads: Fixes download status being incorrectly shown as “Download Aborted” even though download was auto resumed already. • IAP downloads: Fixes “Download Aborted” and “Resume” button been shown even though the respective sound was already resumed. • IAP downloads: Fixes green arrow animation on progress bar which was stopped if either app went into background or user switched to a different app screen. • IAP downloads: Shows an additional small download progress bar at top edge of screen (iPad only) to make it clear the app is downloading a sound set, even if an already installed sound is currently selected on screen. • IAP downloads: Fixes installation status filter not having used the actual latest installation status of all sound sets (i.e. immediately after download or removal of a sound set). • IAP downloads: Distinguishes now between “Queued for Download” for non-installed sound sets and “Queued for Update” for already installed sets. • Audio Unit UI: Fixes sound selection list from being cropped if AU UI height inside AU host app was rather small. • MIDI recorder: Fixes crash on 2nd iOS “Open with …” request for user imported MIDI files. • MIDI recorder: Supports now MIDI files with “.midi” file extension (instead of being limited to only “.mid”). • Sound selection: Fixes readability issue of placeholder text regarding search filter options if iOS was not running in dark mode. • Volume knob: Shows now that MIDI CC#7 is associated with this control. ¹ NOTE: This version asks you for permission to access the local network, which is required for Audiobus to work on iOS 14 and higher. If you are not using Audiobus you can safely ignore or decline this permission request. You can also grant and revoke this permission under iOS Settings -> “Privacy” -> “Local Network” at any time.
