I’m not aware of any interface doing this by itself… all interface I know can do it together with a DAW or some other software… but non by itself…
In the UR series manuals it says you can put effects on the inputs, and it kind of says you can also put effects on the headphone mix(es).
So its a bit vague…they use mix 1,2,3 for different outputs in the UR28 (that desktop interface) for example, and you can save dsp settings in the actualy hardware.
