This may be old news to most of you, but I just discovered the usefulness of Windows magnifier for working with transients. Rather than zooming in to edit and out to navigate, it really helps to have the floating magnifier available at the cursor position.
The magnifier has been updated in Win10 and seems to work most gracefully for me when the magnification window is docked in a separate monitor; it's out of the way, but available any time I need to really be precise.
The Sonar MIDI microscope does this well in PRV. but I miss it when I'm working with audio. It would appear that as I age, the necessity to see what I am doing has become the mother of my invention.
