Read full description

Rivet 04 - Comb is a resonant comb filter built for techno and industrial. Put it on drums, synths, or any bus to create metallic resonance, pipe tones, and reverb-like tails, from subtle shimmer to aggressive industrial texture. Comb works both as a standalone app and an AUv3 plugin. Comb combines feedback resonators with internal saturation for rich harmonic colour. Pitch the resonance to your key, add chord intervals for harmonic resonance, or push it into metallic destruction with the HOT mode. KEY FEATURES • Resonant comb filter with pitchable tuning and chord modes • DRIVE saturation inside the feedback loop • LFO modulation for shimmer and movement RIVET SERIES / OPEN SOURCE • Comb is part of my Rivet series of AUv3 effects plugins targeting techno and industrial genres.

AUv3 Effect • Works in AUv3 hosts such as AUM, Drambo, Logic, and Cubasis IN-APP PURCHASE Comb includes In-App Purchases for optional tipping. Tipping does not unlock any additional features as all features are already available.
