Oto Boum - Routing Question with Analog Mixer and Ableton

Hey guys!

Maybe I’m just to stupid to get this right, but I can’t get my head around this thing. So sorry if there might be an easy solution for this that I’m totally overlooking.

My setup right now contains a Mackie Onyx 1620i which is connected via Thunderbolt to my Mac and Ableton. I multitrack every peace of hardware gear through the channels of the Mackie to Ableton, to apply FX to taste and have everything going in the current moment, so I’m able to record everything properly.

Now my idea was to get the Oto Boum on my Master Bus. I know, everything would work so so easily with Analog Heat as a Plugin on the Ableton Master Chain, but I poorly don’t gel with its sound. So I can’t figure out how to apply the saturation and compression from the Oto Boum on the Ableton master bus by connecting it to the Mackie without losing multitrack recording in Ableton AND listening and recording to the compressed and saturated sound of the Oto on the master bus in Ableton. Is this just as difficult to manage as I’m thinking atm? Maybe the Mackie does not have enough outputs for that?

Much appreciate some ideas and answers! And again, sorry that my head doesn’t come up with it.

One way i can think of:

Can you route signal from DAW into Mackie mixer?
If you can multitrack with it then i think it should be possible.
In that case you can create send the signal back to 2 spare channels on the mackie and route them to one of the subgroups which will go back to your DAW.

Also you need to connect your BOUM to inserts on those spare channels.

Some kind of send/return plugin should make it easy for you in the DAW.

If no subgroups then you might need to sacrifice 2 prefader aux channels and send it there instead.

No subgroups. I will check this tomorrow, if there is any chance to get the Ableton master back into the Mackie. Can’t imagine how this should work for now, because Ableton tells me, there are only one stereo output with my Mackie selected as audio interface.
