Rivet 04 — Comb is a resonator for iPhone and iPad. Use it on its own, or load it as an AUv3 plug-in to turn drums, synths and buses into metallic, pitched, beating, springy and chordal textures. Tune the main note anywhere from 70 Hz to 1.2 kHz, add chord notes, lock the tuning to a scale, and choose a Lush, Beating or Springy character. Then shape how long it rings with Decay and Damp, add grit with Drive and Hot, and bring it to life with modulation and strumming. Everything sits on one screen in eight sections: PRE EQ, RESONATE, VOICE, TIMING, MOTION, BODY, POST EQ and OUT. The HARMONICS display shows which notes are ringing as you play. KEY FEATURES • A tuned main note plus chord notes, with Lush, Beating and Springy characters • Decay from 0.1 to 8 seconds and damping from 800 Hz to 10 kHz • Drive and Hot for grit that stays under control • Band, Scale, Chord, tempo sync, retrigger, motion and strum options • Tempo-synced modulation from a 1/32 note to 8 bars • EQ before and after the resonator, with sweepable mids • Mix keeps your dry signal clean and in time, with Output from -18 to +6 dB • Four quality settings, from Off to HQ • Factory and user presets • Fits small plug-in windows and makes use of larger ones, with full iPhone and iPad layouts AUv3 PLUG-IN Works in AUv3 host apps such as AUM, GarageBand and Cubasis. Every feature is included; optional tips don't unlock anything.
