Joe Topjian’s latest Rivet module brings classic comb filtering to iOS in a streamlined package. It offers adjustable delay time, feedback, and damping controls that create everything from subtle metallic coloration to strong resonant peaks and notches. The effect is particularly useful for adding character to drums, creating vocal-like textures, or generating interesting harmonic movement on synths and guitars.
The app runs as both a standalone effect and an AUv3 plugin on iPhone, iPad, and Mac, with very low CPU usage for running multiple instances in demanding sessions. Its clean, pedal-style interface keeps the focus on sound rather than complex menus, so you dial in the desired effect quickly. Pair it with the earlier Rivet modules — Rivet 01 – Console, Rivet 02 – Room, and Rivet 03 – Verb — for layered processing chains that add grit, space, and movement in one cohesive workflow inside AUM or Logic Pro for iPad.
Key features include:
- Classic comb filter with adjustable delay time and feedback
- Damping control for smooth or metallic character
- Low CPU usage for stacking multiple instances
- Standalone and AUv3 effect compatibility
- Simple, focused interface in the Rivet series style
