The Lighting Controller

I'm using ShowXpress and sometimes when I activate a scene in Live mode the Intimidator spot 155s will automatically reset, I'm not sure why it happens and haven't seen anyone else post about it any info on why this happens will be very helpful

Not even specifically the spot 155s just any reason a light would automatically reset on specific scene

Make sure that you have not accessed the reset function in the scene it happens in. It sounds like you have a value that is being activated in a scene that causes the reset. Funny thing: I had no idea this was even possible until looking at some new lights earlier today. If that function number is enabled and the value is select for reset, it'll cause it to do that. This is a convenience feature to prevent from having to get to the unit physically for a reset. Looking through the manual for your 155 it shows that on channel 10 (in 11 ch mode) with values of 148-247 it will reset.
