New toy: a ~$100 MIDI controller. These are normally used as a music mixer for live music, DJ-ing, etc. My usage for it is quite a bit different: Image editing. The application that I use for image cataloguing and basic camera RAW image editing is LightRoom, from Adobe.
Using a free plugin for LightRoom called "MIDI2LR", I've mapped the controller's dials, sliders, and buttons to LightRoom tools. It's easy. The first time I plug in the controller and once in LightRoom, I activate any control on the pad and MIDI2LR opens a dialog that lets me choose from organized menus which LightRoom tool I want to associate with that control. The process is very intuitive. I mapped it out in advance and had it set up in a few minutes. I only have to do this once and save the mapping file.
The dials, in rows of 8, I've set for red, orange, yellow, green, aqua, blue, purple, and magenta adjustments. The adjustment rows are for adjusting those colour's Hue, Saturation, and Luminance.
The sliders correspond to primary adjustments of Colour Temperature, Tone, Exposure, Highlights, Shadows, Whites, Blacks, Clarity, and Vibrance. The buttons let me navigate my photos, undo/redo adjustments, zoom in/out in increments, select white-balance presets, attach ratings to images etc.
This will speed up photo editing greatly. This image was edited with the controller! Once I get to the point where I don't have to think of what control does what, I can just focus on the image and make my adjustments with my left hand. This will replace a lot of clicking around with the mouse to various tabs and on-screen sliders. I noticed that while navigating through my images, as soon as I touch an editing control, it takes me directly to the editing mode on-screen. The fine-control and having my most used tools handy on one physical device is game changing. If I need more controls, I can simply add another controller. There are many on the market, starting for as low as $40 with a few controls.
I've just added coloured dots for the dials and I'm in the process of makeing lables for the sliders and buttons. I'll post an image of the controller again when it's all finished.
