The Mad Scientist VST3 - Parallel RMS Compressor Interface

Parallel Compression with a Tube Heart.

The Mad Scientist is a parallel RMS compressor built around a simple idea: the more you drive the input, the more character you get. Even-order harmonic saturation is baked directly into the input stage - no separate drive knob, no menu option. Push the gain, the tubes light up, and a subtle warmth gets added before the signal hits the compressor. Back off, and it cleans up.

Underneath the steampunk shell is a full-featured dynamics processor. Fixed 4:1 ratio keeps the compressor musical without requiring you to think about it. The Mix knob blends the compressed wet signal against the clean dry signal for natural-sounding parallel compression at any setting. M/S mode processes the mid and side channels independently so stereo width stays intact even under heavy compression. Auto-release adapts program-dependently - fast when the compressor is working hard, slow when it is barely touching.

Parallel Compression

All the Density. None of the Squash.

The Mix knob blends the compressed wet signal against the uncompressed dry signal - classic NYC-style parallel compression, dialed in from a hint to full commitment. The fixed 4:1 ratio is tuned for bus use: musical, predictable, nothing to overthink. Most engineers find their sweet spot somewhere between 60 and 100%.

Mix - 0 to 100% parallel blend. 50% = full body, intact transients
Fixed 4:1 ratio - Bus-calibrated, musically transparent
RMS detection - Responds to program energy, not just peaks
Auto-release - Fully left = program-dependent, adapts continuously

Input-Driven Saturation

Push the Gain. Hear the Difference.

Even-order harmonic saturation is built into the input stage - there is no separate drive knob because it does not need one. Push the Gain control and the tube overlays glow progressively while the saturation scales smoothly with the signal. Back off and it cleans up. Both the wet and dry signals carry the color from the input stage, so the harmonic character stays consistent at every Mix setting.

Gain - -12 to +12 dB input trim, drives saturation amount
Tanh saturation - Even-order harmonics only - warm, not harsh
Three-segment tube display - Tied to input gain, not output level
Pre-parallel split - Saturation applies to both wet and dry signals

M/S Processing

Compress Without Collapsing the Image.

Toggle M/S mode and the plugin encodes your stereo signal to mid and side channels, compresses them independently, then decodes back to stereo. The center stays controlled while the sides breathe - no width collapse, no mono-ification. Useful on full mixes, wide stereo buses, and anything where parallel compression in L/R mode starts narrowing the image.

M/S toggle - Switch between L/R and Mid/Side processing
Independent compression - Mid and side channels processed separately
Width preserved - Sides compress independently without affecting center

Metering

Two VU Needles. One Truth.

The dual VU meters show output level on left and right channels independently with 300 ms analog ballistic response - the same integration time as a real VU meter. When the needles track together, the stereo image is holding. When one pulls ahead, you know before your ears do. When bypass is engaged, the needles decay gracefully to rest rather than snapping off.

Linux System Requirements

Tested on Ubuntu 22.04/24.04, Debian 12, Fedora 40. Requires one system library for license verification:

sudo apt install libsodium23        # Ubuntu / Debian
