Description:
An analog equalizer modeling plug-in — featuring an original hybrid analog-modeling system.

Modeled after a real-world analog equalizer. Every frequency step, saturation curve, and harmonic structure has been captured and recreated.
Four Analog Modeling Modes: Choose the balance between CPU load and reproduction quality—ranging from a straightforward, traditional design to modeling that tracks circuit dynamics. Two “hybrid” modes can be offloaded to the GPU, while the other two remain on the CPU—a choice dictated by the nature of their operation rather than any technical oversight.

Standard
A traditional design that reproduces the static characteristics of the hardware while remaining light on CPU resources. It responds to the current signal level; while it accounts for how the unit behaves at any given level, it does not track changes over time.

Hybrid− / Hybrid+
A true hybrid analog modeling system. Rather than responding solely to the incoming audio, it also considers the recent signal history—reacting to how the circuit was behaving just moments prior—something a static model cannot achieve. The “plus” version analyzes the signal over a longer window, resulting in better noise performance and greater sonic clarity, though it places a higher demand on the CPU. Thanks to optimized digital signal processing, the Hybrid+ mode can actually help reduce CPU load.

Professional
A distinct modeling approach that requires maximum CPU power. Instead of looking back at a fixed segment of the signal, it retains a memory of what just occurred and uses that to construct the next moment, allowing it to stay as close as possible to the original hardware unit. This is precisely why it runs on the CPU.
