I've been using this keyboard for a short time and am already disappointed in it. The key marked "Click," which would be for turning on and off the metronome click, doesn't do that at all: it actually toggles the "Cycle" mode on and off. Just waiting to find what other mistakes have ben made. It's looks neat, but it doesn't do me any good if the keys are mismarked. I'll be sending it back.
It is the most comprehensive Logic Pro shortcut layout ever seen.
Just a hint. If you remember in Logic to go Alt+K and under Option to choose the right keyboard size then all the shortcuts work as they are suppose to do.
