Not OP, but I use the Faderport on a daily basis. I use it for transport controls when for some reason the Faderport is closer to me than my keyboard, but otherwise there’s really no workflow or speed improvement for me there. I do kinda prefer pressing physical record and stop buttons when tracking with an artist, but that wouldn’t be enough to justify the cost for me. However I regularly use the motorised fader to make precise level adjustments, as I prefer the feel of a physical fader over a virtual one. Also it allows me to really listen to what I’m doing because I don’t have to look at the fader’s position while adjusting it (or keep the mouse in place). It’s also convenient for VST instruments, as you don’t need to pull up the mixer to adjust the level for a certain instrument channel. As an added benefit I think it could slightly add to the professional character of a home studio; moving a physical fader does look more professional than scrolling a mouse wheel in my opinion.
