If you can replicete the error where it is the wrong channel that are saved then file a bug report on it.
At the moment I have reported one with the RGB segment where I don't have the color selection part meaning that I am not able to set the color on the segments.
Regarding the strobe - sound.
If you look at the fixture I created then I have moved all programs to macro instead of using the gobo.
Additional I have made the sound as macro and used the "show in" function so it is shown in the beam panel.
(I forgot to use "blank" ikons on the not used macros so there are some red X in the macro panels)
I find that it is a good way to do it but others may think different and in that case you actually need to try it out to figure out if it is the way to do it or if you think it is confusing your fixture and then eventually don't add it to the fixture.
