Hello,
I just got an idea as I started testing some features for 4.10.0 (the idea ist not related to any of the new features though). I think it could be very useful in many circumstance for example when performing live lights where you have just a few moments to prepare the next setting like when you do lights in a disco environment where you for instance can get the information what the next song will be just a few moments before it happens.
Therefore a system where you can prepare the next "constellation" (active chases, their speeds, colours etc.) without an actual effect on the current output before you set it to active would be useful I think.
I guess - depends on how it is implemented currently - this could be rather quickly achieved by having a third mode for a frame (or maybe a mode for page of a frame), where you can set the frame from inactive to "arm" which would allow that you can already perselect chases, speed values and stuff which only really send the output from the moment when you set it to active finally.
I already tried to implement a behaviour like this by using submasters for each frame, but LTP channels are making problems when this is done that way.
