Hi all,

I thought this was a Model 12 problem, but seems it's an Ableton one... I've been working in studios for 20 years using logic, ableton, reaper, etc so I know my way around input routing etc.

First time setting up the Model 12 with Ableon 12 and it sees all the input channels. I have signal going to all of them, and they all appear in the Model Mixer Meter app just fine. But channels 1/2 won't send signal to Ableton. I fired up Logic, and it can hear and record all the channels no problem.

I've spent hours on this issue so I'm here to see if anyone else has encountered this? Really messing up my setup to not be able to record two of the channels.

Thank in advance
 
So it turns out Ableton is getting a very very very weak signal from 1/2. If I crank the gain all the way till it's distorting and totally unusable, Ableton will get a bit of a signal. Logic is receiving normal strength signal on all channels no problem. Anyone have this issue or may know what is going on? I've isolated it to Ableton and it's very bizarre and frustrating.
 

EUREKA I found the solution, thanks to this above thread. Apple Mic Isolation Mode. For some reason it didn't affect Logic. This was driving me insane, if anyone else has this problem it's the stupid built in mic on a Macbook
