Not necessarily. It depends on the function. Fingering obviously becomes much faster because left hand stays on the macro keypad. Other functions are slightly more difficult as well, so it’s “worth my time” to move to the keypad. For example, I find myself using the tuplet macros. I just hit the 3:2 or 2:3 button, and voila!
I do think it depends very much on workflow. I tend to enter all top voice first, then fill in intervals below, then articulations, then playing techniques (for me that’s just upbow and downbow). So I’ve grouped menus accordingly. First pass I use the keypad very little. Second pass my hand stays set on the intervals menu, to quickly add intervals below. And so on.
It’s not faster for everything… I made a macro key for “lengthen note duration” and found it was better to use the default alt-shift-right arrow. But 1. Some functions require multiple steps, and 2. It’s nice to assign tons of shortcuts and not have to remember them all.
