Improvements & Bug fixes

• Fixed a memory leak in the Track Editor which could lead to instabilities due to (too) high memory usage after editing a large number of tracks

Playout
This release fixes a bug that was introduced in release 1.18.7 where, when playing or queueing up a web or live stream in the playout playlist could cause the application to crash.
This has been fixed in this release. Web and live streams play correctly, also connection issues with web streams are handled correctly again.

Track import
ID3 tags were sometimes skipped when importing tracks into the database. This has been fixed.

Settings / Macros
Added functionality to enable macro execution only on specific machines.  

This is useful in setups with multiple Power Studio instances, where some instances are only used for production purposes. In these cases it is now possible to have only playout machines execute macros (and don't have production machines 'steal' the macros from them), while the production machines still can have the Item Download Plugin enabled, so they are able to generate valid playlists.

Playout
Improved reliability of forced playlist breaks, especially in multi-studio mode. This fixes the issue of filled out commercials or top-of-the-hour news bulletins not always triggering correctly.   

Release 1.18.5 introduced a bug where, when linked tracks had the Next Start-cue point aligned with the file's end, sometimes two tracks would be started simultaneously. This has been fixed.  

Also some edge-cases that occurred when switching from or to a live studio, near the end of hour are resolved.

Mix editor
Fixed an issue that could cause the UI of the application to lock after making an edit in the mix editor, when the database's response took longer than expected.

Improvements & Bug fixes

• Improved handling of database errors and timeouts
• Numerous performance improvements
• Updated external libraries- Small fixes and improvements

Known issue
Adding live/web streams to the playlist causes the application to crash when the the live/webstream item is played or cue'ed up.

Playout
Release 1.18.5 introduced a bug where, when switching to Automation mode, the players sometimes incorrectly displayed a currently playing track moving to the Automation channel. The playout continued to play on the player's original channel and switched to the Automation channel only when the next track started, as it should. This has been fixed in this release.

Playlist
When a track is being played in PFL and it has been dragged to a new location, sometimes the item at the "old location" would not play though PFL when clicked immediately afterwards. This has been fixed.

The playlist is now always scaled to fill all available width when opening a Playlist screen.

Mix editor
When an intro of a track is trimmed past the end of the previous track, that track is no longer placed at the end of the previous track, but is placed at the original start next position.

Improvements & Bug fixes

• Timestamps in the REST API no longer include time zones and are no longer converted to UTC but are assumed to be local times.
• Small fixes and improvements

Library Import tool
Added support for migrating Aeron Studio PostgreSQL databases to the Power Studio database.

Mix editor
Made it easier to trim tracks outside the bounds of the previous or next track.

Playlist
Added a dialog to warn against navigating away from playlist with changes. (Which would result in losing these changes.) This dialog can be turned off by the user on a per-machine basis.

Added "Planning artist analysis" screens to the Playlist and Track Browse screens. This new function gives an overview of when an artist has been scheduled, in a similar manner as the "Planning track analysis" screen.

When adding/removing items from the Playlist Editor, the scrolling-position is maintained (prevents jumping up of the playlist...)

Fixed an error that would occur when a non-supported file type was dropped into the playlist.

Playout
Added support for the *.s48 file format

In some edge cases, an extra track would be started when playout was switched to automation-mode close to to the end of the hour. This has been fixed.

When playing a set of linked tracks in the playlist and switching to automation playout mode, the playout would sometimes switch to be heard on the soundcard/channel configured for automation playout. The player that started the playout however, would still be showing as playing. This has been fixed.

Visual Radio Assist plugin
Tracks with special (non-ascii) characters in its title or artist name, would result in questionmark-characters in the titles that are displayed in Visual Radio Assist. This has been fixed.

Improvements & Bug fixes

• Updated the external libraries used to their latest versions
• Small fixes and improvements

Playout
Improved general stability by fixing a memory leak that sometimes caused unpredictable behavior or crashes.

During playout, the start time of filled out items is now also calculated when the next playlist is not yet loaded.

Item download plugin
Fixed an issue with some (podcast) downloads, where the web server disallowed the download (by returning error 403). Fixed this by adding a user-agent header to the download request.

Axia / Livewire control plugin
Added more fine grained control to the Livewire control commands, the Livewire plugin sends to the mixer. This allows for working around an issue between version 2.11 of the Axia Livewire driver and an IQ mixer core, when using the "ready state" function or updating the channel's labels.

Improvements & Bug fixes

• Updated the external libraries used to their latest versions
• Small fixes and improvements

Improvements & Bug fixes

• The REST API used the swagger-ui instance hosted by swagger.io. However because of swagger.io starting to enforce strict transport security, it is no longer usable for the locally hosted REST API. Because of this, we have replaced it by a swagger-ui instance hosted at the power-studio.nl domain.

Multi Studio
Fixed Forced playlist breaks change not triggering in Multi Studio mode.

Playlist
The players would sometimes jump back to the previous position, e.g. when items are dropped in a player...
This is now fixed.

Fixed issue that caused the playlist's start times to reset to the original values when the start times are recalculated.

Improvements & Bug fixes

• Improved loading of some VST plugins
• The Power Traffic interface does no longer download commercials in Training Mode (to prevent blocking future days from planning new commercials...)

Updated to Microsoft .NET framework 4.8
Power Studio has been updated to the latest .NET framework version. Because of this we have been able to update the database and other libraries that Power Studio uses internally. This increases the performance and solves a large number of smaller bugs that we were not able to fix because we were stuck on old versions of some of these libraries. Also the BASS audio library has been updated to the latest version.

As a result of this support for Windows XP and Windows Vista has been dropped. The application should work on Windows 7, Server 2008 R2, Server 2012, 8.1, Server 2012 R2, 10, Server 2016 and Server 2019, however we only actively support it on Windows versions which are currently supported by Microsoft.

Drag-and-drop on players
It is now possible to drop tracks and files directly onto the players of the playout playlist. This replaces the tracks which are currently loaded into that player and in the playout playlist.
This makes for much faster last-minute changes on-air.

Playout playlist
An indication has been added to the playout playlist, indicating if a playlist has a floating, exact of manual program change.

Improved forced program changes, both stand alone and in a Multi-Studio environment.

Improved time calculation within the playlist.

Corrupt playlist lines are now automatically removed from the playlist, to prevent the playout from stalling.

VisualRadioAssist link plugin
An integration had been added for VisualRadioAssist, using the VisualRasioAssist link plugin.
This allows for starting video clips in exact sync with Power Studio's audio playout as well as triggering track titles. Power Studio can trigger actions in VRA when items are started in the Cart players. Power Studio also informs VisualRadioAssist of a configurable number of upcoming tracks. (up to 100)

REST API
A REST API plugin has been added for custom integrations with Power Studio.
This plugin adds functionality to access and update playlists, control playout and fetch detailed track information. The REST API has an integrated Swagger document which makes the API self-documenting and allows for automatically generating client code for the API. SwaggerUI functionality has been added to increase ease of development.

Please note that support on API client development falls outside regular support and might require additional consultancy.

Mix editor
Added a render function to the mix editor which can render the contents of the mix to a audio file.

ASIO playback
Improved stability of the playout through ASIO audio devices.

Axia / Livewire control plugin
Version 2.11 of the Axia Livewire driver contains a bug which can cause high DPC latency values on some machines. In those cases pops or clicks can be introduced by the driver when Power Studio sends GPIO commands to the driver.
This version of the Axia / Livewire control plugin implements a workaround that works around this bug to reduce the occurrence of these pops or clicks.

The track titles being sent to the Axia mixers display are now trucated to 10 characters as per the LWRP protocol.

Xml / icecast / shoutcast title plugins
Improved the way the next item is determined in de Xml title plugin.
In a multi-studio environment, titles are only sent by the Power Studio instance which is OnAir.

Configuration transformation
Added configuration transformation functionality to the Configuration tool, which makes it easier to deploy modifications in the configuration file.
The transformation files use the Xdt transform syntax.

Item download plugin
Improved reliability of file copy actions withing the plugin.
The rendered filename is made even more unique (in case the download action is triggered 2 times and the file is still locked.

Playlist creation Switched order of the Artist separation rule and the Track separation rule, so artist separation is dropped before track separation. Which would prevent a specific track from being repeated too much, when not enough tracks are available because of artist separation.

Power Traffic integration
Reduced load load on the database when commercial blocks are imported in the playlists.
Fixed issue with importing commercials which have already been (accidentally) removed from the database.

Log files
Added functionality to automatically clean up log files after a configurable number of days.

Improvements & Bug fixes

• Added configuration tool and other Power Studio utilities to the Windows Start menu.
• The Fill out checkbox is unchecked when the Clock Format line is moved to a place where Fill out is not allowed.
• Real time lines can now have the Fill out flag enabled in generated playlists.
• Fixed defect with switching from Training mode to Live assist mode.
• Fixed possible database issue when files with a very long filename are dropped into the playlist.
• Added Application settings with a setting for Process priority and an experimental setting for Low latency Garbage Collection.
• After updating the database, perform a normal VACUUM as opposed to VACUUM FULL which takes longer, locks the tables, has a risk of timeouts.
• Various small fixes and improvements

Playlist
The playout playlist now retains the times a which a track has been started, even when the playlist is refreshed from the database.
Improved error handling for dragging tracks in the playlist from Windows Explorer.

Multi Studio
Made the Central Playout-side of the Multi Studio network code more resilient and less likely to hang the playout in case of a connection issue.
Fixed a possible freeze in Multi Studio mode, when "Force playlist breaks in live mode" is enabled.
Fixed a defect in Multi Studio mode that sometimes caused the countdown color to not change when the live studio became active after xx:50...

Download Item Plugin
Fixed defect in re-rendering files that were downloaded by the Download Item Plugin.

Library Import
Added support for Jazler Radiostar version 2.11 and up to the LibraryUpdate tool.

Improvements & Bug fixes

• Fixed excessive logging in the VM140 plugin
• Added throttling to the commercials-replace burst on a new playlist and first playlist of the day
• Added caching for Power Traffic and Block Import macros when the playlist is created which reduces the load on the system
• Fixed repeated loading/unloading when the last playlist of the day is unloaded before midnight (with floating playlist transitions)
• Improved sending notifications to other Power Studio instances on playlist and settings changes
• Improved the warning message that is shown when a generated playlist is too short
• Fixed issue in version 1.17.3 that would sometimes give errors when the software was installed for the first time on a certain machine

Shoutcast Title Plugin
Added support for Shoutcast V2 to the Shoutcast title plugin.
Added more sensible defaults to IceCast & Shoutcast title plugins.

Item Download Plugin
Made some improvements to better handle unreliable network situations

• Copying source files and publishing rendered files now also has a retry mechanism (just like ftp and http)
• The rendered filename is made even more unique (in case the download action is triggered 2 times and the file is still locked
• All retry times have been increased to 5 seconds

Fixed some small defects in the Item Download Plugin UI

Default values
Added better default values for

• MixEditor mode: Manual start
• Players time mode: Time remaining with intro
• Power Traffic macro processing moment: When the first playlist of a day is loaded

Improvements & Bug fixes

• Added extra confirmation before deleting Tracks + Audio files
• Added Id-field to the playlist export
• When the connection is lost in a Live Web Stream, the next item to be played is recalculated, before starting the next item.
• The MixEditor now handles changes in playlist lines that are already loaded in the MixEditor better.
• Updated LabJack driver download link to https://www.power-studio.nl/support/tools
• Upgraded the BASS audio libraries
• Various small fixes and improvements

IceCast title plugin
In the IceCast title plugin, a seperate server and port number can be used for each end-point when the "Server per mountpoint"-checkbox is checked.

Improvements & Bug fixes

• The Now Playling plugins now don't publish the item when in Training Mode.
• Fixed issue with remote forced program change events that sometimes caused the first item to be skipped.
• Improved connection stability for Vm140 cards.
• Fixed issue with navigating through the fields of the Track Editor dialog with the Tab key.
• The Track Editor dialog can now be closed with Esc and saved with Enter key.
• The Track Browser can now be closed with Esc and saved with Enter key when it is used to select a track from the playlist.

Download Item plugin
The Download Item's settings screen has been redesigned to improve usability.

The plugin can now automatically split a file into multiple parts which can be separated by a separator-sound or can each have their own music bed.
Splitting a file is done, based on the silence between the different parts.

A file that has been split into multiple parts can have different beds at the end of the file, e.g. for weather or a closing part.

Note: The Pre-start time now plays before the end of the previous part and does not cause the previous bed to stop earlier. This give you more control in configuring the perfect segue between the different parts, but may require you to review the Pre-start time for the Bed close, if you are currently using the "Fade-out pre-start" setting.

X Keys control plugin
Support X-Keys XK-24 keyboard for remote control. It can be used to start jingles, control the mixeditor (e.g for voicetracking) navigate to the next playlist in live mode, and switch between live-assist and automation.

Playlist export
Playlist can now also be exported in CSV format.
Exports can be made for the current hour, current day and for a specified date range.

Axia / Livewire control plugin
The plugin can now display the player's Track-titles/artists in the Axia mixer.

Playlist scheduler An item's day part now always follows the playlist's corrected start time. (Corrected, means that 11:59:54 is regarded as 12:00:00)
Because of this the day part of fillout-items in playlists that take up more than 60 minutes, is now always correct.

An issue has been resolved in the "Ignore category separation when only one item is selected"-function.

Playlist Insight now indicates why an item has been disallowed or when Category Separation has been ignored.

Improvements & Bug fixes

• Added duration and EndTime to Xml now-playing-file.
• Corrected name of "StartTime" element within the BroadcastMonitor element to "updated" in the now-playing Xml file, which better represents it's function.
• Made an improvement to the available tracks estimation in the Clock Format editor.
• Fixed a defect in the Multi-Studio module.
• Fixed a defect in the Mix Editor that allowed a track to be placed before it's preceding track, which is not supported.
• Fixed a defect in the Analysis tab, that caused the data to be mirrored in the graph.
• Improved central settings store

Download Item Plugin
This update adds support for HTTPS downloads with TLS 1.1 and TLS 1.2.

A growing number of sites are no longer allowing TLS 1.0 to be used in HTTPS downloads. (E.g. NOS in the Netherlands) This results in the error "Could not create SSL/TLS secure channel". This update fixes that by enabling more secure protocols.

Note that this requires at least version 4.6 of the .NET Framework Runtime to be installed.\ We recommend downloading the latest version here: https://smallestdotnet.com/

Improvements & Bug fixes

• Improved the way volume changes during playout in files with different sample frequencies is handled
• When selecting a file with the file selecting dialog in the plugins, the chosen file would sometimes not "stick" without first exiting the field, e.g. with TAB. This is now no longer necessary.

Improvements & Bug fixes

• The batch add screen now displays the track that is currently being imported
• When a very large batch of tracks is being imported, the software could become less responsive for some time because of background processing that is done when tracks are added. This has been fixed.
• Improved speed of identifying which files are already in the database.

Improvements & Bug fixes

• Improved navigation speed in the Mix Editor
• Improved speed of Delete Playlist function
• Improved the loading speed for playlists
• Mix Editor is more resilient to database timeouts
• Added indication in the playlist when a commercial block from Power Traffic contains a spot that has already been deleted

Playout Engine
Fixed issue that caused some sound devices to initialize incorrectly, causing silence or unexpected behavior on some computers.

Added a setting to force the playout engine to fall back to legacy DirectSound drivers, even when WASAPI drivers are available. This improves stability with some 'buggy' sound devices.

Improvements & Bug fixes

• The spacebar no longer triggers pre-listening playout, when using the Tracks Browser's search box
• When a Track is used in a future playlist, it is now no longer possible to change it's audio file
• Improved the speed of the Track-delete function
• Fixed deadlock that may occur when a live/web stream continuously fails
• Fixed issue caused web streams to sometimes play through a live-player, when automation was activated

Playout
Added setting to automatically switch to automation mode and start the news/fillout items when in live mode and the next playlist does not have floating start enabled. The "Force playlist breaks in live mode"-setting can be enabled on a per-machine basis.

This functionality also works in multi-studio mode.

Tracks Browser
Added a "Add single track" button, to add single track to the database (note that Batch Add is still the recommended way to add tracks to the database!) Also the select file button on the Track Edit screen has been implemented.

The PFL-function can now be activated using the space bar (just like in the Mix Editor). Of course CTRL+P also still works. When PFL is playing in Tracks Browser and Playlis and another track is selected (with cursor keyse of mouse), that track is played in PFL.

The Tracks Browser can now also filter on Content Type.

Clearing the searchbox using the delete-button, now no longer attemps to delete the selected track.

Carts Player
Added the ability to remove jingles from the Carts Player list.

Web Streams
Added retry and reconnect functionality to the playout of Web Streams.

When an invalid or disabled Web Stream is started, the players are no longer blocked. Silence is played instead. If the stream still can't be played in a couple of seconds, the software continues with the scheduled backup tracks.

Library Import
The Library Import tool now supports importing Zenlex databases.

Playout Engine
Upgraded the BASS audio engine to the latest version. Power Studio now favors WASAPI drivers over WDM drivers (when available) for playout. An issue that sometimes occured when dropping files into a playlist as well as a specific deadlock situation has been fixed.

Improvements & Bug fixes

• The Item Download plugin now has file selection dialogs for local/network file settings.
• Added improved logging for failed WDM audio drivers

Item download plugin
Two new wildcards were added to the Item download plugin:

• DayOfWeekNL - Day of week for the playlist in Dutch, e.g. maandag
• DayOfWeekNr - Number of the day of the week for the playlist starting on 1, e.g. 1(=Monday), 2(=Tuesday)

Also the FTP-downloader now correctly interprets wildcards in file names and directories.

Playlist
The Intro-time column in the playlist screen, now takes into account any cuts off the beginning of the track.

Improvements & Bug fixes

• Improved reliability of cue-point scanning during track-import
• Fixed excessive memory usage growth which sometimes occurred during recording of voice tracks and with the recorder
• Fixed issue where the Mix Editor was not able to receive focus (and did not react to keyboard short cuts as a result of that), when it was opened though the playlist's context-menu
• Fixed an error that occurred when exporting playlists to PDF files, when certain versions of Internet Explorer are installed

D&R Airence control plugin
Each channel of the D&R Airence mixer can now be assigned to any player or cart (in pre-select mode). It is now also possible to choose to use button- or fader-start.

Improvements & Bug fixes

• Improved stability and resource-use
• Fixed defect in the multi-studio function, that caused all audio-channels to switch to silent when one of the studios updated their settings
• Improved the storing of local settings

Playlist
When switching from live-assist to automation, the players are immediately reloaded. This used to be after the first track had finished. Especially for users with less than 4 players in use, this is a significant improvement.

Bug fixes

• The cursor in the Track Editor's player now moves with the current position again. (this broke in version 1.15.4)
• The Year and Tempo columns in the Track Browser are now shown correctly.

Recording
In "Advanced Audio Settings", a setting "Process recordings offline" is added which allows older computers to perform encoding and processing tasks (e.g. applying processing or encoding to FLAC, MP3) after the recording is finished as opposed to on-the-fly.

Fixed issue that occurred on some newer machines running Windows 10, were occasionally some pops occurred in the recorded material.

General improvements
A large number of stability improvements have been administered. This fixes a lot of edge-cases where Power Studio would sometimes display unexpected behavior.

Bug fixes

• The auto-update of playlists and settings, triggered by other Power Studio instances would sometimes stop working. This has been fixed.
• Various minor fixes and optimizations

Playlist scheduler
Under special conditions, some hard-to-plan lines, could be altered by the playlist scheduler when altering/dropping unbreakable rules. This has been corrected; altering/dropping unbreakable rules while creating playlists now does not result in permanent changes in the Clock Format.

Taking a track's Bpm into account while creating playlists has been optimized.

Labjack U3 plugin
Added support for U3-HV. Because of restrictions within the U3-HV device, the pins FIO0-FIO3 can not be used.

Some small bugfixes.

Bug fixes

• Minor fixes in the Track Editor's, mix-point editor.
• Improved stability of remote updating of playlists and settings.
• Improved performace of the multi-studio functionality.
• Various minor fixes and optimalizations

Track editor
In the Track Editor, cue points, such as Start Point, Fade in, Intro, Start next and Fade out can now also be set by dragging them to the desired position with the mouse.

Play start/stop keyboard shortcuts (CTRL-P / Spacebar) now pauses when pressed a second time, as opposed to stopping and resetting it's position

Download items plugin
The Download Item plugin, now also supports downloading items from a podcast/rss feed, such as podcasts or church services through Kerkdienst Gemist.

Bug fixes

• Fixed defect where zooming in caused the height of the waveform to change
• Multiple bugfixes in the LabJack plugin

Playlists
When a playlist is modified on a different computer, this change is immediately visible on other computers having that playlist open. This means that a producer can add an interview or track while the show is already on air.

In the playlist screens it has been made possible to add a column with the intro times of the tracks.

Tracks browser
In the track browser it is now possible to add columns containing album title, intro time, track tempo and year.

Track editor
The wave display in the track editor has been improved. Start, intro and next-start-positions are now more clearly marked. It is also possible to zoom in deeper and more precise. The mouse can now be used to zoom in and start playback.

Mix editor and recorder
The recording routines have now been implemented in unmanaged code, to provide even more recording-stability.

Plugins
The settings of the Item Download Plugin (content ingestion) and are now shared between all Power Studio instances.

The settings of the Shoutcast, Icecast, Omnia A/XE / Telos ProSTREAM and Xml titles plugins are now shared between al Power Studio instances.

All changes to the settings of the plugin are now immediately active. Only turning a plugin on or off, requires an application restart.

External schedulers
The block import in Power Studio now also handles external playlists that combine all hours of a day into one file.

A Power Gold Link-tool has been added to automatically link Power Studio tracks to the corresponding items in Power Gold.

Configuration
When a setting had been changed, this change is immediately active on all running Power Studio instances, even if they are on a different computer.

Bug fixes

• The grid-settings of the playlist screens is correctly used.
• Fixed the encoding of the settings-files on the local computer
• Fixed a calculation error in the track-count estimates in the Clock Format editor, which occurred when new items were added to a Clock Format.

Mix editor and Recorder
Fixed issue that sometimes caused Power Studio to use more memory and decrease the recording quality when a large number of recordings were made.

Mix editor
Spectacular improvement in zoom in/out-speed of the mix editor. Also the mix editor does not block the UI anymore during zoom. A threading issue was also fixed in the mix editor.

Training Mode
A bug was fixed in the Training Mode that sometimes caused tracks that were added to the Playout Playlist did not show up.

Mix editor improved
You can now zoom in with the mouse wheel. Zooming in is also more precise. Playout in the mixeditor can now also be start with the spacebar and by double clicking the mouse on the location it must be starting from.

Training Mode improved
When switching to Training Mode, a new playlist can immediately can be selected. (The mode opening with no playlist selected was confusing.) In Training Mode, the playlist duration is now correctly counted down is the right upper corner. In the Mix Editor the Previous Mix / Next Mix buttons are also operational during Training Mode. When the playlist is empty, some toolbar buttons/context menu items were still enabled, but did not do anything because there was no playlist. This has been fixed.

External schedulers
Using the menu-item "Export tracks…" in the Tracks region of the navigation bar, the tracks database can be exported to a comma separated text file, which can be used to import/sync the Power Studio database with an external scheduler or any other external system e.g. the request page of a website. Also the Power Studio block-import (which can be used to import) van now import macros e.g. news download.

More sound encoders included by default
The MP3 encoder is now included with the installation by default. AAC/AAC+ encoding is also included with the installation. Note that, because of licensing constraints, Winamp needs to be installed to use these AAC/AAC+ encoders.

AAC recording can also be added by downloading the free Nero AAC encoder and placing the file "neroAacEnc.exe" in Power Studio's Encoders folder. The Nero AAC encoder can be downloaded from http://www.free-codecs.com/nero_aac_codec_download.htm and other sites.

Support for MP2 recording, can be added by downloading the TwoLAME encoder and placing the file "twolame.exe" in Power Studio's Encoder folder. The TwoLAME encoder can be downloaded from http://www.twolame.org/.

Various small improvements

• Fixed defect that caused a non-floating playlist to not start on time after a 1-track-playlist.

• Fixed cart players & mixeditor control for Velleman & LabJack control plugins
• Fixed problem that in some conditions caused the on screen player controls to only control the first player
• Fixed connection problem in multi-studio communication between Power Studio instances
• When the connection with the remote central playout system is lost, the remotely playing indications in the playlist, are removed
• LiveWire channels now can be set to empty
• Fixed problem with the V-Mixer control through LiveWire in a multi-studio setup
• The maximum wait time when closing Power Studio has been decreased to 30 seconds
• Improved the reliability of the next-player indicator for the Velleman, LabJack, Midi and LiveWire control plugins
• Fixed defect in the Item Download plugin, that cause the Minimum Duration setting, to only be enforced when a music bed was added to the download.

Added training-mode
In training-mode, the changes made to the playlist are strictly local and are not written to the database. Also, in a multi-studio environment, the studio in training-mode does not go live. This is ideal for practice-sessions or recording complete shows, without trashing the station's playlist.

Added LabJack U3 remote control plugin
In this release we added support for the LabJack U3 interface module, in addition to the Velleman modules. The LabJack module has more IO, is faster, more robust and comes in a neat red case.

Control multi studio switching from Central Playout
It is now possible to control all on/off air switching from the Central Playout node. (Until now, each studio controlled its own switch, which is still possible.) This functionality can now be leveraged by the LiveWire plugin, which can control an Axia Core's V-Mixer to do the actual switching. This function will be added to the other GPIO plugins in later versions.

Added support for .OPUS files
Support for the playout of this excellent open compression format is added to Power Studio. We can now play files, encoded in this format and play icecast stream in OPUS format.

Remote license update
Power Studio can now be updated, automatically, through the internet. Very convenient and ideal for last minute updates…

Added Aeron to Library Import
The Library Import tool, now also supports conversions from the latest PC Radio family member: Aeron. Upgrading to Power Studio never was this easy!

Added Advanced Audio Settings
Power Studio's audio-pipeline is configured in such a way that every machine should be able to run without issues. However, sometimes it is nice to be able to tweak a buffer size, sample rate or player count. With the Advanced Audio Settings dialog, we make these previously hidden settings available to power-users. Use with care…

Various small improvements

• Mix Editor button now also loads the mix form the active playlist form to the Mix Editor.
• Fixed issue with how Power Studio handles regenerated playlists for today.
• Playout players now display the '&'-sign correctly.
• The playlist header of empty playlists is now displayed correctly.
• Fixed Add Track-buttons for empty playlists.
• Updated audio engine to the latest version.
• Fixed problem with the Power Traffic background sync.
• Various small fixes.

Added user settings management functions
Added functionality to allow an admin to reset a user’s settings (which contain screen positions, etc..) It is also possible to copy the settings from another user or copy one’s own settings to another user. It is now also possible to set the settings for the Default User, which determines the screen positions when no-one is logged in and supplies the default screen positions when a user opens the settings for the first time.

Tracks Browser extended
The Tracks Browser now displays the number of tracks that are currently selected in the Tracks Browser.

Improved the PC Radio Library import
An extra text-line now indicates more precisely what the import tool is doing at the moment. We also made the tool more resilient against inconsistent data-storage in de PCR database, and improved the searching for audio files by the import tool

Fixes and improvements

• Fixed issue with Playlist Insight module, where the Clock Format for the analysis lines is not set for fillout lines.
• Power Studio no longer allows a playing item to be linked to another item, when this would change the player it is playing on.
• When multiple items are playing and AutomationMode is set to AutomationChannel, keep all playling items in the automation player. (This does however cause that one of the players remains empty until the 'Double playing' player is stopped.)
• Fixed the "invalid input"-error that sometimes pops-up in the live-screen configuration screen.
• Fixed 'invalid handle'-error in the playlist generation screen.
• Improved logging of device+channel assignment on SoundPlayers. Assignment of No sound device is no longer logged as "no stream could be found".
• Preventing extra EnginePlay actions when a player is being played by the automated playout- fallback meganism.

Added multi-line display to players
The size of the playout-playlist players already could be changed by dragging the right-bottom corner of the players screen. This functionality has been extended to display title and artist on separate lines, if the available size is large enough.

Added “Criteria-seperation” functionality to playlist scheduler
This new functionality allows you generate even more balanced playlists, by setting rules to the number of consecutive times a criterion may appear in a playlist and how many positions this criteria will be blocked afterwards. E.g. after two dance tracks, three other type of tracks or two other type of tracks after a rock track. Note: These rules can only be set for the Track content type.

Added “Max per playlist” functionality to playlist scheduler
This new functionality allows you to limit the number of times a criterion may appear in a playlist. E.g. have only two Dutch records in a playlist. Note: These rules can only be set for the Track content type.

Added “Playlist insight” module

The Playlist insight module, gives the music director a perfect understanding, why a certain record was picked by Power Studio. The clock scheduler form already gives a rough estimate of how many choices are available for a specific clock-line, but the Playlist insight module shows you exactly how many choices were available at the time of playlist creation. You can even dive in deeper and view the playlists’ Search Plan which shows exactly what filter-parameters were used and what search-strategy was actually used to pick the track. From this module it is also possible to navigate directly to the related Clock Format line or Track editor to fine tune either of them, if needed.

Added remote control functionality to Recorder screen

The recorder’s record and play functions can now be controlled by the Midi- and Velleman- plugins. This allows you to, e.g.  automatically start recording every time the microphone is turned on, so you never miss that amazing quote. Which you can immediately share with Power Studio’s social media integration!

Power Traffic communication is now more secure

TLS encryption has now been added to Power Traffic and the communication between Power Studio and Power Traffic. (Note that Windows XP does not know how to handle the SNI-certificates that is used for this. Because of this, Power Studio still uses the normal communication mode on Windows XP.)

• The Library Import tool, now also supports importing PC Radio Express (6) through the NexusDB ODBC driver.
• The playlist export save dialog, did not suggest the .pdf file extension correctly on some computers.
• Fixes race-condition that could cause some files (e.g. commercials) to be started simultaneously on older computers.
• Fixed possible race condition in the end-of-file logic.

Added printing (and export to PDF) functionality for playlists
Playlists can be sent to the printer and can be exported to PDF files. The playlist can be customized by replacing the logo.png file in the Power Studio\Templates folder.

Added updating track / artist repeat value from the Track Browser popup menu
This allows for easy updating of multiple tracks at the same time. E.g. when moving tracks to another category.

Added filtering on language to the Track Browser

Added track rotation to the Format Scheduler/Clock Format
Normally tracks are selected using a random component. By selecting the "Rotate tracks" checkbox in a Clock Format line, the track that has been scheduled the longest time ago is selected from the tracks that matches the format's criteria, track/artist separation and rating rules.

Select/deselect complete rows and columns in the Track's dayparts
This makes configuring day parts easier.

Added Recorder functionality
Manually record (e.g. from broadcast). This recording could be stored and uploaded to e.g. SoundCloud. Recordings are stored in the Recorder file path (this can be configured in the Recording tab in Options and Settings. Users can also manually export the recorded file, e.g. to a network or thumb drive.

This release fixes the following issues:

• Fixed issue where the wait-cursor would sometimes remain active.
• Improved storing/restoring the tree-separator in the Tracks Browse screen.

Dit is in deze release opgelost.
