Bug Fixes.

June 14, 2024

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.

June 12, 2024

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.

New Features: • Sends. Each non-mixer track can now send a percentage of its output audio signal to mixers. • MIDI Learn directly from audio units UI, and new parameter handling. AU Parameters can be automatically added to the parameters list by simply tweaking from the UI. • An advanced MIDI monitoring system, which can simultaneously monitor inputs and outputs of multiple items (tracks, parts, custom translators, MIDI aliases, and audio units). • The signal levels in the mixer and on the tracks now show the true decibel levels, with a peak indicator. Also the volume levels can now exceed 0 Db. • In the song properties, users can now configure dynamic and non-dynamic properties (properties that changes from section to section). • The song volume can now be a dynamic property. • Multi Translators. • Scripts in Custom Translators. Users can now write their own codes to program custom translators, which opens up endless possibilities. • Groups of translators can now be saved as “translators chains”, which can later be recalled anywhere. • Custom and Multi translators can now be added directly to Audio Units. • Users can now access a new and expanding database of custom translators and chains of translators. • KeyStage keeps track of the last 10 songs that were loaded, which can be easily accessed from the Files menu. • Player Unit’s timelines can now be synced. • Audio Unit presets can now be changed with program change and bank select messages. • A new option to automatically load invalidated audio units. These audio units load in the background and does not interfere with other audio units and MIDI signals, so will not interrupt the live performance. • The font size of lyrics can now be adjusted with a slider. • Solo function is added to tracks. Also global mute and solo control buttons are added to the bottom bar. • Battery level indicator is added to the bottom bar. • “Low refresh rate mode for audio signals” is added to improve the performance of low-end iPads. Further performance options are on the way. • Users can now create full backup files, which allows them to store and share their whole setup. • User’s Manual. • Info buttons on several different parts of KeyStage, which automatically opens the related section in the User’s Manual. Improvements: • Live consoles layout is slightly changed. So now the bottom bar is visible while the live console is on, which allows users to access transport controls, tempo/time signature/metronome controls, MIDI monitor, global solo/mute buttons, battery meter, and DSP meter. • Several other UI changes and improvements. • Volume,Pan, and Sends are now considered as track parameters. CC assignments on these parameters are stored on the track rather than the audio unit. • Audio Unit Parameter values are now visible in the parameters section. • 'Disable All Parameters' button in the parameters section allows users to disable all parameters. • Major performance improvements in MIDI routing. • Deleting an item from a list can now be done with the standard left swipe gesture. • In the MIDI Learn view, the users can now manually select the CC value. Bug Fixes: • Possible crash when loading songs in iPadOS 1.48 and above is now fixed. • Hanging/overlapping tracks/parts/sections, while copying them is fixed. • Spikes in the DSP meter when changing sections are now resolved (this was a virtual bug, there was not an actual spike in the DSP). • Several bug fixes involving Midi Processor Units. • The problem with player units stopping in the middle of an audio file with a different sample rate is now fixed. • There was an issue related to controlling volume and pan of input, player, and mixer units via MIDI. This is fixed. • Lots of additional minor tweaks and fixes.

April 26, 2021

New Features: • Audio Unit view frame can be cycled through a set of preset frames. • On the Main Mixer, you can now double tap on volume and pan sliders to assign their default values. Improvements: • You can now import songs directly into KeyStage. • Audio Unit view can now be moved around by holding and dragging from the bottom bar as well as the top bar. • "Save Changes" on the Main Mixer now applies to everything, including track states, parameters, and the master volume.• Audio Unit view frame can be cycled through a set of preset frames. • Users have now the option to disable autosave. When autosave is disabled, changes that you make in a song is stored only if you manually save it. Bug Fixes: • When “Same as Incoming” is selected on a track with a AU MIDI plugin, the channels of the MIDI signals produced by the plugin remains unchanged. • While editing track/part/section names, delete all button (x) can now be pressed. • In player units, the loop problem for short audio files is resolved. • Resolved possible crash when (system reset) MIDI message is received. • Relative control of custom translator with AUParameter outputs was not working correctly when they are activated the first time. This problem is resolved. • Hardware MIDI connections are now tracked by their unique IDs, which allows you to use multiple devices of the same brand independently. • Problem with storing buffer size and sample rate changes is resolved. • Some problems related to storing full states into parts and tracks are resolved. • Custom translators with global/custom event inputs and with sysex outputs would cause a crash. This is now fixed. • Lots of additional minor tweaks and fixes.

February 5, 2021

• AUv3 hosting. KeyStage can now host instrument, effect, and MIDI processor audio units. • New mixer units allows you combine audio signals, turning KeyStage into an audio mixer. • With the new player units, you can play wav, mp3, and m4a files, add marker points, automate actions (like play, stop, move to a marker etc.) using custom translators, or trigger certain events (like changing sections) when the player reaches a certain marker . • New input units allows you to use the microphone input, or the hardware inputs of a connected audio interface. • New mixer view allows you to control volume levels and pans of all tracks, connect effect units, and connect units to mixer units. • KeyStage 2.0 has a multi-track recorder, which lets you record any number of tracks simultaneously (unlocked via in-app purchases) • The new transport controls allows you to play all instrument, effect, and MIDI processor audio units in sync with the built-in metronome. You can use global tempo and time signature, or assign different tempo and time signature to sections. • With the new range limiter, part ranges are no longer limited to single intervals, you can now assign any set of notes and intervals. • Additional minor tweaks, bug fixes, and performance improvements.
