So I tried to adapt the transition code you guys wrote for me to be in a constant loop (ie. scroll to color 1, scroll to color 2, repeat), however I'm getting some weird errors appearing. These errors don't exactly stop the effect from working, however after a few loops of the cycle the app crashes. I'm running the effect in a new thread as to not interrupt the main program. http://pastebin.com/aE1XcLJf

Errors that appear in the debugger:

Call to native Chroma SDK function DeleteEffect failed with error: Unknown: Unknown. (1168)
Call to native Chroma SDK function SetEffect failed with error: Unknown: Unknown. (1168)

according to MSDN
Damn enter
According to MSDN that error is:
ERROR_NOT_FOUND
1168 (0x490)

Element not found.

Trying to format messages in Gitter on phone is annoying
IIRC someone (Brandon?) had a similar error with multi-threading, starting to wonder if the SDK has some kind of issue with multiple threads.
What happens if you init on the same thread updates are made in?

@Sharparam The loops runs fine on the same thread, although it obviously locks it up to only running the loop.
So its probably multithreading which is the problem.

@technicaldaniel and it also works when both init and updates are done on the other thread?

@Sharparam I would assume so however it's difficult to test due to the sheer amount of Colore calls in my code.

@Sharparam, @technicaldaniel I had issues with multithreading, too. I also have the feeling if you call the SDK at the same time from two different threads that can cause issues and throw exceptions. I have a Helper method in my code that does all the Colore work and locks around it. Never had any issues afterwards.

Can you guys think of a work around without using threads?

Possibly, but if the SDK itself doesn't support multi-threading our options are limited but it should be possible by using more locking (like we are currently doing in the initialize functions)
Locking does incur a performance cost as well but it might be negligible

Agreed with Adrian there, also making use of locking around certain tasks
Also if you're doing a while loop for animations, you'll need to throttle it to about 24 miliseconds
