I've noticed on Harrison Mixbus, there is a monitor section where you can set a volume boost for soloed tracks. That way you can set your interface output to a nice lower volume to mix at, but when you want to solo a particular track... It then will boost the DAW output by the set level in the monitor section to allow you to hear the part better, without having to constantly adjust the output knob on the interface or on the master fader when going in and out of solo.
This is a really useful feature, and one I would love to see in Studio One.
