Lemur Audio SIMON v1.6.4 VST3 AAX [WIN]

SIMON’s EQ and its DIGITAL saturation are both inspired by the same hardware original — a mastering equalizer whose harmonic character is deliberately clean. After the first release, users asked for something more pronounced, so we added a second harmonics engine: a mathematically perfect model of an OP-AMP from a different piece of hardware, with three L/R matrix modes: EQUAL — both channels share the same harmonic structure; MODERN — each channel carries a subtly different harmonic structure; and VINTAGE — each channel has a distinctly different harmonic structure. It comes as two saturation models — OP-AMP, true to that circuit, and OP-AMP LP (Linear Phase), the same chain with its upper-band phase rotation resolved — alongside DIGITAL, the saturation voiced after SIMON’s own hardware original. OP-AMP and OP-AMP LP run in the HQ and ULTRA quality modes for guaranteed quality and cleanliness. We have also modelled further non-linearities that bring dynamics, liveliness and musicality into the whole system — surpassing the hardware they are drawn from.

OP-AMP — true to the hardware

The authentic OP-AMP is faithful to that circuit: its signal branch feeds a transformer, and that OP-AMP → transformer path rotates the phase in the upper band — exactly like the unit it is modelled on. It is the sound of that hardware, character and all.

OP-AMP LP — Linear Phase

OP-AMP LP models the very same signal chain but resolves that upper-band phase rotation — a cleaner, phase-linear take on the same harmonic character. Reach for it when you want the OP-AMP colour with a perfectly linear top end.

A true mastering equalizer

Two independent channels, each with high and low shelves, three fully parametric bands and its own output trim — a complete, symmetrical mastering EQ built around a central INPUT TRIM that feeds the analog-style saturation stage. With AGC on, the level leaving the EQ is matched automatically, so you can equalize freely without driving the saturation any harder.

Three parametric bands

LOW, MID and HIGH — each with its own GAIN, stepped Q and a mastering-grade frequency grid, on both channels. Broad and musical for tone-shaping, tight and surgical when you need to fix a single frequency, with exact, repeatable recalls.

Musical high & low shelves

A broad high-frequency shelf for air and top-end weight, and a low shelf switchable at 50 or 100 Hz for warmth and bottom-end control — the classic, gentle mastering moves that sit outside the parametric bands.

Analog-style saturation

INPUT TRIM drives a built-in analog-style saturator — the harder you push, the more harmonic colour and density SIMON adds. DIGITAL follows the hardware the EQ itself is drawn from, a notably clean unit, so it stays subtle; OP-AMP and OP-AMP LP come from a different circuit and push the harmonics considerably further. The live SAT indicator shows exactly how hard it is working, and the per-channel OUTPUT trim lets you match level so you judge tone, not loudness.

Link & Mid/Side

LINK ties the left and right controls together for fast, symmetrical stereo moves. M/S switches processing from Left/Right to Mid/Side, so you can equalize the centre and the stereo sides independently — mastering-grade stereo control.
