01Overview

Maserati GRP is built for the group channels that most effects overlook. Rather than treating each track on its own, it focuses on the sum of related parts, such as a backing vocal stack, a drum kit or layered guitars. The developer describes its job as adding the final touch of EQ and gentle compression that makes a group feel connected. It is available as a VST2, AU or AAX plugin on Windows and macOS.

03In depth

Group Compression and Tonal Settings

GRP combines subtle group compression with low, mid and high frequency controls. The compression is designed to glue a set of tracks together rather than squash them, so the group keeps its dynamics while sounding more unified.

Dedicated settings target specific sources, including backing vocals, drums, keys, strings and master buses. Each preset-style starting point reflects a different group type, so you can begin from a sensible setting and adjust from there.

Workflow: Insert, Send and Full Mixes

GRP offers separate modes for use as an insert or a send effect, which lets you choose whether the processing applies directly to a channel or is blended in from an auxiliary track. Master mode is intended for full mixes and stems.

PRGM mode is aimed at programmed drums, where the developer says it adds life to the sound. With 13 presets covering background vocals, drums, guitars and more, you have a quick way to audition group treatments.
