KVR Audio

Hi all - looking for some help.

I have 2 Audio Interfaces - EVO 16 and SSL 2

I am using the EVO 16 mainly but also want to be able to send audio to the SSL simultaneously so I can use it as a 3rd Headphone output. How do I do that?

I'm comfortable creating separate Headphone mixes via Aux channels and setting their Outputs to the relevant input on the EVO but I can't work out how to also send audio from an Aux to the SSL using the same method.

Any help will be appreciated!

A macOS Aggregate Device can be built. How?

Here I had always trouble with that Aggregate Device method.

IMO better (if possible) to combine audio interfaces between them via digital connection like ADAT (for example). So only 1 audio interface is in use by macOS.

I never had an issue with aggregate devices in macOS. This is actually one of the main features that distinguishes it from what you can do in Windows.

On mac: aggregate devices. Google it.
On win: Asio4All in Einstein mode does something simular.

Oh wait, Logic is mac only

Thanks! I'll give this a try and hopefully will get this to work.

I always found aggregates a pain, but my setups tend to be quick and dirty, only to be broken down and reconfigured the next day. However, for a permanent, monolithic setup:
