Crash when using a Midi command to pause a timeline [fixed]

[spielberger]

Dear Support,

I'm working on a music show using timelines for audio and light. The show is not yet completed but I tried to run the already finished timelines by MIDI commands. But there is a serious issue with MIDI which causes the complete software to crash. I don't know if it is because of our slightly new workflow, but I don't think so.

My Workflow
What I basically do is run timelines for a seqeunce of one or two songs. Between the sequences/songs - at the end of a timeline - I manually activate an "intermission"-scene (called MOD_MAIN) on another page to load a new timeline in the background. When the talent starts the next song the next timeline is played and the MOD_MAIN-scene is switched off using single-button-mode on the intermission-page at the same time the timeline starts - this allows a smooth transition. This has worked for 5 shows on all older software versions!
But now we wanted to add more videoscreens so we have to roughly synchronize the start of a timeline with an external videoplayer. Due to different filesizes sweetlight has slightly different loading-times, I simply worked around this by adding a pause at the first second of the timeline and then sending synchronized MIDI Cues to two different systems - one is Sweetlight playing the preloaded audio and light timeline - the other triggers a video on the external player. So I updated to Version 8.2.27 to have the great new feature of controlling the Timeline-PLAY-Button via MIDI. Because my show is completly triggered by a MIDI-command cuelist.

The Bug
With just one timeline it worked fine BUT by switching to the next I encountered a serious bug: When a MIDI device is activated or present, the stopping of a running timeline causes Sweetlight to crash completly. There is no way around it execpt disabling the MIDI devices. I made a video showing the complete problem: https://drive.google.com/open?id=10ZCEK ... Luxnd3Rpcs

I uploaded my show so that I can send it to you if you want to take a look.


System: Windows 10 - 64bit
Version: 8.2.27


Thanks for your help and support!!!

I forgot to mension one important thing

IF THERE IS NO MIDI-COMMAND FOR PLAY/PAUSE it doesn't crash! You will see it in the video in at last minute.

Please unzip and install this file in your software folder https://download.thelightingcontroller. ... _Debug.zip
And make again your tests.
You should see more informations regarding the error in a window, when the crash occurs.
Then please post a screenshot of the error message.

I attached the error message - couldn't see more than that, because when the software crashes the debug disappers after 1 - 2 seconds.
