I'm definitely going to buy a few modules at a time and then see what I'm missing or where I want to go.

And my bad. That 3:1 is definitely not a mult haha. I meant to put this instead https://afterlateraudio.com/product/mult/. The MI Links look great though. I guess it would be better than the ALA one since I could do mult a stereo in, and still have space free for more inputs. Perhaps I'll have one ALA mult, and one links. Does this seem like a good idea?
