It is quite common to use the LUFS Meter exclusively for
creating faders up mixes and the Multimeter for measuring
the loudness and the dynamics. With dedicated startup
presets for both of them, a faster workflow can be established
then by only having a Multimeter at hand.
If you have created projects in the past that contain the
LUFS Meter, you probably would like to keep a LUFS Meter
license, such that you can reopen these projects from the
past.
