Release Notes Bug Fixes: 

• There was a migration issue from ver 2.1 to ver 2.2, which might result in crashes on some song files. This is fixed. • The issue of not properly storing full states on tracks (for certain audio units) is resolved. 

• "Backing All Data” function for Dropbox was broken. It is fixed. • Instrument preset suggestions were not being properly stored, and because of that KeyStage was suggesting the same presets for the same MIDI connections over and over again, even if the user cancels. This is fixed.

Release Notes Introducing Anytune Count-In to start in time for a perfect entrance. Our new Count-In feature combines visual and audible cues, ensuring you begin in perfect sync with the music, no matter where you jump into the song. Anytune uses your chosen time signature and the song’s tempo (BPM) to display and play a count-down so you can start playback with perfect timing. Start by setting Count-In as the default action in Playback Settings, replacing the old Delayed Play feature. Then, customize your Count-In experience by selecting the number of bars, enabling or disabling the accompanying sound. Adjust the time signature and BPM directly in Tune Info. Count-In supports any and unusual time signatures like 5/4 (3+2). When Count-In is enabled, pressing play triggers the countdown. You can also access Count-In and Tap-In by long-pressing or right-clicking the play button, while maintaining normal play/pause functionality for the button. Tap-In lets you set the playback tempo by tapping the beats of a bar. You can use Tap-In to start playback directly or initiate the Count-In after tapping in. See anytune.app/count-in for more info. We added stability improvements and bug fixes including: - added MIDI fine pitch adjustments - fix for song not playable - lyric scrolling issue across songs - smoothed waveform scrolling on intel Macs

KeyStage is a master controller, AUv3 host, and audio mixer app designed mainly for keyboard players.

New version 2.2
Old version 2.1
Release Notes New Features: • Major performance improvement: A new option that allows KeyStage to automatically suspend inactive instrument units, which greatly decreases DSP load. • Seamless transition function is added, which creates two copies of audio units and automatically alternates between them. The above performance improvement also applies to these copies: inactive copies becomes idle. • Certain audio units causes a spike in DSP (and thus causes a glitch) while changing full states. A new option to temporarly pause rendering of an audio unit while its changing full states is added to prevent such glitches. • Several new features related to player units: transpose and speed adjustments, Bars+Beats mode with snap option, syncing with global tempo, selective sync between player units, etc. • “Player units with no parts on the active section are muted” option is added. With this option on, player units behave similar to instrument units, they are muted if there is no corresponding part on the active section. The same option is also added for Input Units. • The scripting language is reworked from the ground up. Lot of new features, including variable declarations, new variable types (current types are int, bool, float, string, track, part, section, playerUnit, and their array versions), properties of variables, a new smart auto-complete feature, a new log system with custom text, etc. • Current time is now displayed on the bottom right corner. • The four in-app purchases, which unlocks differnent types of units, are removed. All units will be available for all new and existing users (even if they did not purchase any of the IAP’s in the past). • Added a Tip Jar for those who'd like to support future development. Improvements: • When you load a new song, KeyStage now loads all audio unit plugins simultaneously, which greatly reduces total loading time. • When you start KeyStage, it’ll automatically load the last song and the setlist. • Users can now create nested folders inside "Audio Files" and “PDF and JPG Files” folders. Browsing through these nested folders in player units and in the live console is greatly improved, with the ability to search all files in all subfolders in any folder. • Song Properties has a new look, similar to preferences. • Timing issues related to player units are resolved. All operations like looping, moving between markers, are sample accurate and has no latency. • New input and output options are added to custom translators related to transport controls and player units. • New flash option for metronome is added. Bug Fixes: 

• The issue related to changing song via external MIDI signals is resolved. • In iOS16.x and above, player units may have audio dropouts if where are several audio units and/or player units. This issue is fixed.
 

• In iOS17.x and above, the time tempo/time signatore view could not be opened. This is fixed. • While creating a full backup file, all existing full backup files we also added to the new backup file. This is fixed. 

• Some issues related to moving/coping files are resolved. • Several additional improvements and bug fixes. Known Issues • If an audio unit gets invalidated while KeyStage is loading a song, it might cause KeyStage to crash. The crash happens before the audio unit notifies KeyStage about its invalidation. • If the connected audio interface becomes disconnected, KeyStage asks the user to reset the audio engine. Under certain conditions (which I’m still working on to identify), KeyStage may crash during reseting its audio engine and rewiring the connections. • If two or more keyboards are connected, there is a small possibility of MIDI signal leakage between the two inputs. This only happens (and very rarely) if note signals are send from one keyboard and simultaneously CC signals are send from the other.
