I have a Focusrite Scarlett 18i20 and there’s software mixer called ‘Scarlett Mix Control’, which is a free download on their website but because always need multiple inputs, am not familiar if the 2i4 also utilizes ‘Scarlett Mix Control’…but bet it may appear under downloads available for your audio interface.

There, you can set-up how you monitor, audio/midi routings…ASIDE and CONJUNCT with whatever DAW you are using, or some, like my Scarlett 18i20, can run standalone as a summing mixer and configure routings/advanced through ‘Scarlett Mix Control’.

It may look complicated at first, but it’s incredibly thorough, if you can think of routing, can almost all be done there, then save those set-ups as templates for Scarlett Mix Control.

If this does not apply to your 2i4, it’s a good thing to know, especially expanding tracks via ADAT/Light Pipe. Hope it helps to some degree…you may not have known there’s additional downloads and tools/applications for your interface.
