I just got the ES-9 Eurorack Audio + CV Interface - can I just use it to mix inline and use the audio ins and out without going to the iPad - as in like in inline Mixer module - or is the entire purpose to use the ES-9 to get audio out as an audio interface?

There is a mixer built into the ES-9 that would allow you to do that. But it's really hard to understand how to configure it. And the most obvious way to control it is via a web interface on a computer, which is cumbersome. Also, it's not a live mixer where you can move a slider and it takes effect immediately: you change the settings, then you upload it to the ES-9 to take effect. So while possible in theory, I would strongly advise against it!
