The folks that make editing software put a lot of work into making their products as user friendly as they can, but there’s something so unsatisfying about clicking and dragging sliders to the exact point that you want them. Sometimes a hardware solution is in order.
Knobroom is a program that allows you to adjust your Lightroom setting using a MIDI controller normally used for music production. Of course, you don’t need a MIDI port to make it work – most MIDI controllers offer USB support these days.
Knobroom is still in its early stages, so there will be some bugs here and there. It’s available now for Mac and PC.
