Get WIDE Meters in Pro Tools
This option is a bit hidden, but I personally prefer it.
The default volume meter size is a bit narrow, to make them WIDER – USE THE POWER CLAW!
Mash down on all three modifier keys
WIN:(Ctrl, Start, Alt)
MAC:[Ctrl, Option, Command]
and click any meter
This changes the meter size in both the Mix and Edit Windows. Repeat to go back to the default size.
