You are correct. There is no dedicated monitor mix app for phones (Android or iOS). However, you do at least two options, depending on what you want:
- Create a custom layout in CustomControl. Once you’ve done that can have your users connect via the iOS or Android application. I’ve done this and it’s worked well. It did take some time to complete, but the band loved it.
- Mixing Station now supports the Avantis mixer, so that’s an option with a cost
It would be nice to have a dedicated IEM/monitor app, but none of the other pro-level mixers (dLive or iLive) had them. And, if I remember correctly, other manufacturers like DiGiCo don’t have them either. I kinda get the idea that when you’re at the Avantis/dLive and higher level, there’s an assumption of a monitor engineer/monitor board present.
