Bismuth: Iridescent Color Resonator Effect by Lunacy

The Chord panel tunes the resonant filters to a chord or scale, shaping incoming audio into harmonically rich textures. Octave, Spread and Root set where the voicing sits in the mix, while Attack and Decay control the envelope, from tight plucks to slow swells.

The Arp section cycles through the notes of your chord at a rate that can run free or lock to tempo. Classic arp patterns are available, along with Random for unpredictable melodic movement and a Chord mode that shifts the harmony over time.

Motion applies continuous amplitude modulation to the resonance. Rate, Strength and Shape control its speed and character, from a smooth pulse to sharp rhythmic bursts, with Unison locking the modulation into a single pulse.

The Filter section decides which frequencies the resonators act on. High and low cutoff sliders isolate a band, Q adds resonance at the cutoff points, Tilt moves the spectral balance from dark to bright, and Scoop attenuates the resonating frequencies to keep tails focused.

Spacing warps and stretches the resonant frequencies so the harmonic series no longer follows a standard pattern. Drift smears the resonance outward for a wider sound, and Shift uses a frequency shifter to change timbre.

Depth sets how much of the processed signal enters the mix, from a subtle shimmer beneath the dry signal to full transformation.
