What it is

Metro v1 by Evertone Project is a BPM-based parameter calculator for mixing and mastering, not an audio processor itself. It reads your session tempo and translates musical note values into precise millisecond settings for expanders, compressors, and glue compressors, so your dynamics processing locks to the beat.

Who it's for

Mixing and mastering engineers who want to set compression and expansion timings using musical note values instead of guessing at raw millisecond numbers.

Key features

• Note-value calculation with BPM sync derives tempo-locked attack, release, and ratio settings automatically
• An ASSIST function recommends starting parameters based on your session
• Three operational modes cover Expander, Compressor, and Glue Compressor duties
• A pendulum-style visual meter with adjustable speed (x0.5 / x1 / x2) shows the rhythm behind your settings
