I have not used a snake for my band since the first Mackie DL came out. That's the beauty of mixing on tablets as a control surface.
The only things that are difficult (but not impossible) are using external effects and controlling your break music.
For effects, if you are using just one setting, say for a delay, no problem, run it back in on an input and you can control from the iPad by level - you can't get on the stage to change a setting though... so, maybe set the mixer and effects on the side where you can get to it. Or, put it by the drummer and have him change it from notes on a set list - even a drummer can change a patch muahahahahs
Then, there's break music. The cure for that is an MP3 player that continuously plays, just bring up those channels when needed.
But wait, you have a singer that uses a track.... sigh. Of course you do if using at a church. How do you deal with that?
Glad you asked. I have the airport's audio run into the dl32r/1608.
I have one of the iPads on stage used for mixing monitors which runs tango remote app in server mode.
I use Tango Remote app from the iPad Pro I mix from to control the iPad and tango player/server on the stage.
I can load tracks, setup playlists, etc.
In a pinch you can stream from the iPad you mix on directly to the airport but be aware that if you lose signal, even for a sec, it might be embarrassing....
So, ironically, after saying I have not used a snake it 5 years, just yesterday, my custom made snake came in...
It's so I can use the mackie for my in ear monitors, and have control of what I hear on stage, even when a pro audio company is doing sound for us, or when we play a venue with house sound.
Very short isolated split snake though, so not some bohemoth, and it's only on the stage.
