Undertone Audio - MPEQ-1 v1.0.3 VST3, AAX for Windows

• Hardware-Accurate Super-Parametric EQ: Faithfully captures the wide Q control range, variable filter curves, and unique phase interactions of the analog MPEQ-1.
• Dedicated Per-Band Saturation Stages: Drive, color, and distort individual frequency bands independently without smearing the entire mix spectrum.
• Unique Vari-Phase Mode: Recreates the organic analog phase response of the original hardware unit.
• High-Resolution RTA Spectrum Display: Real-time frequency visualization with interactive node dragging and visual saturation glow cues.
• Band Solo Auditioning: Solo individual frequency bands via keyboard shortcuts (Alt + 1–4) or interactive GUI headphone buttons.

Super-Parametric Equalization with Harmonic Drive
Undertone Audio MPEQ-1 brings the flexibility of the revered hardware equalizer directly to digital mixing workflows. Designed to solve complex tonal problems that standard parametric EQs cannot address, MPEQ-1 combines precise curve geometry with custom analog saturation topologies.

Unlike conventional digital equalizers that apply global harmonic distortion, MPEQ-1 assigns dedicated harmonic drive circuits to each EQ band. You can saturate low-mid punch, push high-end sheen into soft clipping, or drive snare fundamentals while keeping the surrounding frequencies clean and dynamic.

Modern Ergonomics & Visual Feedback
Featuring a high-definition RTA spectrum visualizer, interactive parameter controls, and multiple layout views (including a compact curve grid), MPEQ-1 integrates vintage analog behavior with modern digital workflow efficiency.

Revision 1 Fix:

• Fixed node grabbing issues on the interactive RTA curve grid.

Version 1.0.3 Updates:

• Range Control Panel: Dedicated central panel to edit parameters of the selected frequency range.
• Band Solo: Direct soloing of individual bands via headphone icon or Alt + 1-4 hotkeys.
• Keyboard Shortcuts: Added shortcuts for Undo/Redo, A/B Compare, Copy, and panel navigation.
• Distortion Visual Glow: The saturation glow now mirrors the exact shape and bandwidth of the driven band.
• Analyzer Calibration: Adjustable analyzer noise floor from -60 dB to -130 dB.
• Enhanced Metering: Upgraded peak meters with clip LEDs and responsive gain readouts.
• Fine-Tuning Control: Adjust parameters precisely using Ctrl/Cmd + Drag or the mouse scroll wheel.
• General Optimization: Reduced CPU utilization and improved UI rendering across open visualizers.

Key Bug Fixes:

• Fixed curve alignment so EQ response traces nodes across the entire spectrum.
• Fixed UI blurriness at fractional scaling factors and scaled right-click menus.
• Preserved dB axis locks per instance across DAW project reloads.
• Resolved Pro Tools automation and preset recalling issues.

Frequently Asked Questions (FAQ):

• Q: How does per-band saturation differ from standard distortion plugins?
  A: Per-band saturation allows you to apply harmonics strictly to targeted frequency areas (e.g., just the mid punch of a bass) without distorting the rest of the signal.
• Q: How do I fine-tune parameter knobs?
  A: Hold Ctrl while dragging any knob or use the mouse scroll wheel over the control.
