Turn one knob. Gecko Comp takes care of the rest — musical compression with instant visual feedback, everywhere you make music. One knob controls everything — threshold, ratio, attack, release. All tuned together to always sound musical. No wrong settings, no menu diving. Load Gecko Comp as an AUv3 effect in GarageBand, AUM, and any compatible host on iOS and macOS. Drop it on a track and you're done.
