KorgDipole v2: Through-Zero Flanger Effect for KORG Synths by Sinevibes

Through-zero flanging is a sweeping effect that depends on the signal passing through zero time difference between two copies of the sound. Around that point, Sinevibes describes a "jet fly-by" character with positive feedback, and full sound cancellation with negative feedback.

The effect uses a sine-wave LFO to sweep the time difference automatically. The developer notes that the original technique used a pair of tape machines, with the difference in speed and position controlled by hand. This version reproduces that movement digitally inside the synth's effect section.

The developer also lists individually chosen parameter mapping, which it says gives a natural feel when turning the controls, and built-in lag filters for smooth, noise-free adjustment.

Sinevibes states that the DSP has been optimized for performance and stability on each supported device type. This matters most when a flanger is swept live or automated, where abrupt parameter jumps can cause clicks.

The lag filters are intended to smooth parameter changes so that moving a control produces a continuous result. Because the set is built only for the listed KORG models, it is best treated as a hardware-specific effect rather than a general-purpose plugin.
