The Maserati GRP Black Friday deal puts 69% off this group-bus plugin, which brings it to $29.99 until Nov 26, 2026. It is a multi-effect plugin from Waves that glues several tracks into one cohesive sound.
Waves built it with Grammy-winning mixer Tony Maserati, whose credits include Beyoncé. The idea is simple: plenty of effects exist for single tracks, but few are aimed at the group channel.
GRP is meant for background vocals, drums, layered guitars, strings and similar groups. Loops and stems also respond well to being treated as one unit, thanks to curated EQ and compression settings.
The compression is subtle. It glues the material together instead of squashing it.
Tony Maserati describes the goal this way: it is not about big effects, but an extra touch of EQ and subtle compression. Try it on backing singers to add polish, or on a whole drum bus to tie the kit together while opening up some top-end air. It also works across a full mix or a stem bounce.
PRGM mode is aimed at programmed drums, where it is meant to add some life to a grid-perfect pattern.
On Mac, Maserati GRP runs on macOS Monterey 12, Ventura 13, Sonoma 14 and Sequoia 15, in VST, AU and AAX formats.
On PC, it needs Windows 10 or newer and comes in VST and AAX formats.
