FEATURE: Added support for the Pixel Distributor Pro 8 and the SYMPL essential2 Node.

FEATURE: Added a new "Scheduler" web application hosted on the integrated webserver. The Scheduler allows to configure starting and stopping SYMPHOLIGHT Sequences at specific dates and times. It includes a configuration for daily, weekly, monthly and yearly recurring schedules. One "Scheduler" can handle multiple SYMPHOLIGHT instances in the same network.

FEATURE: In addition to eDMX (ArtNet & sACN) Credits it is now possible to upcharge the license/dongle with exclusive SYMPHOLIGHT functionality like the Content Management via API or the new "Scheduler".

FEATURE: Added support for e:cue Genius 4 Channel and e:cue Genius 8 Channel MODBUS devices connected via a SYMPL Serial Node (RS485).

FEATURE: Added an option to automatically save the current project at a specified interval. Note, that this does not replace the necessity of a backup of the project.

FEATURE: Removed the requirement that only an equivalent system could be configured as a backup instance. Now, e.g. a SYMPL Core S can be configured as a backup for an LCE3(fx) to maintain at least a reduced operation of the installation.

IMPROVEMENT: Increased the DALI stability and performance.

IMPROVEMENT: Increased the RDM stability and performance.

CHANGE: Updated the included firmware for SYMPL devices to the most up to date version.

CHANGE: Updated the HASP dongle driver to support up to date Windows versions.

FIX: Fixed a rare crash in the case the SYMPHOLIGHT configuration stored on the hard drive was broken. SYMPHOLIGHT reverts to default settings in that case.

FIX: If the Render Engine frame rate was set to more than 35 FPS, in some cases there was no DMX output at all.

FIX: Improved the stability when importing many videos at once.

FIX: Corrected the output of scenes when using generic fixtures with non-default sizes. A scene value for one fixture could have been applied to a neighbor fixture as well.

Workflow Designer

FEATURE: The Observe Controller block now keeps most information persistent. The information is available after reloading the project even if the controller is offline.

FIX: The Dry Contacts block did not initialize to the correct values on project load.

FIX: Corrected the configuration dialog of the Time Trigger and Condition blocks to work with Norwegian locale settings.

ActionPad Designer

IMPROVEMENT: The Action Pad is now updated automatically in all open browsers, when a new project is loaded. A manual refresh is no longer necessary.

FEATURE: The new black level threshold sets the output to zero for pixels with a value below the threshold.

Workflow Designer

FEATURE: More logical sorting and naming of Workflow blocks. This follows the basic flow “Triggers / Inputs -> Processing -> Output / Action”. The property grid has been simplified as well.

FEATURE: A new “Observe controller” block to observe e:net controllers allows maintenance and tracking e:net controller data e.g. on the ActionPad.

FEATURE: The new system status block “Observe System” gives live access to many aspects of the running SYMPHOLIGHT instance. This is useful for maintenance, visualization on the ActionPad or reporting to a central server.

FEATURE: The new blocks “Send to Network” and “Receive from Network” allow transferring data and events from configurable ports over the network. This saves the user from implementing boilerplate code in Scripting for the same task.

FEATURE: Fading from one value to another is now implemented in a dedicated “Fade” block. This allows smooth and easily configurable fading. The “Fade” block supports different flavors of inputs like buttons, switches or GlassTouch devices.

FEATURE: The new “Permit Event” block can disable Workflow events when a condition is satisfied.

FEATURE: New “Build RDM command” and “Send RDM” blocks are implemented for building and sending many RDM commands. Possible targets are all devices (broadcast), a single universe or a single device. One out of many use cases is changing the personality at runtime.

FEATURE: The new “Generic Control Sequence” block can start, pause or stop sequences by their Id. Also, start / pause / stop events from all sequences can be consumed at one place. Easy access to the Grand Master is also offered.

FEATURE: The “Event To Value” block allows configuring multiple named events. When triggered, the named value is pushed to its output.

FEATURE: The “Periodic Trigger” block now provides an interval resolution of 100ms. The smallest interval is now 100ms.
