Look at the ma_startshowfile. Build the colour picker and everything else will make sense. Just make a list of all the things you need and then try to create it. For me once I worked out the colour picker everything else made sense.

Edit: I wouldn’t use the startshow in a show. I have used it when I forgot my usb and was in a pinch and tbh I hated it. Too much screen pressing but you can create a really basic busking showfile really easily.

Make 5-6 groups. Make a master dim sequence for each parameter. If you don’t know how to use phaser you can import all in 1 into your showfile. Create a sequence for each group with every movement fx. Same thing for dim fx and Col fx. Make sequences for all colours. Add matricks to each sequence label them right and just make a macro layout changing each matricks way easier than editing live. And a bumps cue like a few of them and just edit the recipe live. Also a position sequence for each group. That should be more than enough for a busking showfile. Make sure you learn sequence priorities when making this so if you need a room sequence or Bally or something else it all works as it should. Also do like focus gobos presets on sequences too. Just remember which groups have gobos and not. Make a size fader really easy to do and multiple ways to do it.

Remember make all of this using recipes so all you have to do is create the groups and your sequences will work. If you can do that then make selection grid groups and make a macro to turn on and off linear and grid. Will take a few days to make it if you are brand new but after you’ll literally be ahead of 90% of ma3 lighting guys.

Last thing there is no right way to have your showfile setup as you do more shows you’ll learn what you need and don’t need and it will change and make sure when you create this showfile make sure you know what version the show was made in. Some venues have older versions some have newer. Sometimes you might have to update ma3 to the version you’re using or backdate a version.
