Lemur Audio - SIMON v1.7.8 VST3, AAX for Windows

• Dual-Channel Symmetrical Mastering Topology: Two independent channels featuring high and low shelving filters, three fully parametric bands, individual output trims, and centralized Input Trim drive.
• Three Modeled Saturation Algorithms:
  • OP-AMP: Hardware-faithful circuit emulation replicating the transformer branch, including the natural high-frequency phase shift characteristic of the physical hardware.
  • OP-AMP LP (Linear Phase): Shares the identical harmonic saturation profile of the hardware op-amp circuit while eliminating high-frequency phase distortion for transparent tonal coloration.
  • DIGITAL: Pristine, mathematically clean digital saturation from the original SIMON algorithm.
• HQ & ULTRA Processing Tiers: High-resolution oversampling engines available across OP-AMP and OP-AMP LP models to ensure anti-aliased harmonic purity.
• Channel Tolerance Matrix Modes (L/R Stereo Variance):
  • EQUAL: Left and right channels share identical mathematical harmonic structures.
  • MODERN: Subtle harmonic variance between channels reflecting modern high-tolerance component standards.
  • VINTAGE: Noticeable harmonic and component differentiation between left and right channels for expanded analog depth.
• Precision Mastering Filter Set:
  • Three parametric bands (Low, Mid, High) with stepped Q factors and mastering-calibrated frequency grids.
  • Low Shelf filter switchable between 50 Hz and 100 Hz.
  • Broad High Shelf filter designed for smooth top-end air.
• Automatic Gain Compensation (AGC): Automatically adjusts output gain against input drive levels, enabling EQ adjustments without unintended saturation buildup.
• Stereo Matrix Flexibility: Integrated Channel Link for matched dual-mono operation and Mid/Side (M/S) decoding for independent center and stereo-field equalization.

Mastering Precision Coupled with Analog Drive
Lemur Audio SIMON bridges surgical frequency balance with intentional analog coloration. At its center is an Input Trim driving an analog-modeled saturation stage, allowing mastering engineers to dial in harmonic weight before shaping tone with stepped parametric bands.

The updated v1.7.8 architecture introduces circuit modeling of the analog op-amp and transformer coupling stages, giving producers the choice between hardware-accurate phase interactions (OP-AMP) and phase-linear top-end clarity (OP-AMP LP).

Stereo Imaging and Component Variance
Analog consoles rarely exhibit identical behavior across both channels. SIMON emulates this via its L/R Matrix modes:

• Select EQUAL for clinical phase and harmonic alignment.
• Select MODERN for slight stereo imaging nuance.
• Select VINTAGE for distinct left/right analog component behavior that widens the perceived stereo field.

EQ & Filter Sections:

• Parametric Low, Mid, High Bands: Fully parametric frequency bands with stepped Q values and fine gain controls calibrated for mastering adjustments.
• Low Shelf: Dedicated low-end contouring filter with switchable corner frequencies at 50 Hz and 100 Hz.
• High Shelf: Broad, musical high-frequency shelf for adding presence and air without harshness.

Saturation, Dynamics & Routing:

• Input Trim & SAT LED: Drives the saturation circuit; visual LED feedback reflects real-time drive intensity.
• Output Trim: Per-channel attenuator to level-match processed audio against the bypass signal.
• AGC (Auto Gain Control): Normalizes output levels automatically as input gain increases.
• M/S Switch: Toggles processing between standard Left/Right stereo and Mid/Side modes.
• LINK Switch: Binds left and right channel controls for uniform stereo adjustments.

• Supported Formats: VST3, AAX Native (64-bit)

Step-by-Step Installation:

1. System Requirement:

   • Ensure TEAM R2R System v1.5.2 (or newer) is installed on your computer.

2. Uninstall Previous Releases:

   • Completely remove any prior versions of Lemur Audio SIMON.

3. Network Blocking (AAX Users Only):

   • If using the AAX format in Pro Tools, open your Windows hosts file (C:\Windows\System32\drivers\etc\hosts) and add:

     127.0.0.1 lemuraudio.com  
     127.0.0.1 [www.lemuraudio.com](https://www.lemuraudio.com)  
     

   (Note: VST3 format access is automatically handled by the R2R System Network Block Runtime).

4. Install:

   • Run the installer executable and complete setup.
   • Default VST3 destination: C:\Program Files\Common Files\VST3\Lemur Audio\SIMON.vst3
   • Default AAX destination: C:\Program Files\Common Files\Avid\Audio\Plug-Ins\SIMON.aaxplugin

5. Launch:

   • Launch your DAW, run a plugin rescan, and insert SIMON.
