Uni-L Master Limiter (NEW)
Uni-L is a modern master limiter designed to push loudness while keeping the sound pure and dynamic.
At its core is wideband limiting controlled intelligently per-frequency through multiband detection. The limiter response and release timing can be set independently for low, mid and high bands.
A transient detection feature lets you route only certain transients (snare, kick) to clipping for added punch. Quick Start presets with macro sliders are also included for fast results.
Main features
- Wideband limiting with multiband detection (independent Low/Mid/High timing)
- Two-stage slow + fast limiter with integrated clipper
- Up to 32x linear-phase oversampling
- Transient detection routing to the clipper
- Quick Start presets with macro sliders
Michelangelo
Michelangelo is a tube-style stereo EQ that adds the warmth and rich harmonics characteristic of vacuum tubes.
It features 4 main bands (Low / Mid / High / Air) plus 2 switchable bands that toggle between narrow bell, wide bell and shelf. Each band offers not only frequency and gain but also Mid/Side panning, Transient/Body separation, and tube drive.
The Transient/Body separation is particularly powerful — for example, you can take a high-shelf boost out of the transient region so it stays smooth on the ears while the body still sparkles.
Main features
- 4 color EQ bands plus 2 switchable narrow/wide/shelf bands
- Per-band Mid/Side Mix, Transient/Body Mix and tube Drive
- Analog-style dynamic EQ on each band
- Triode / Pentode tube blend
- Crosstalk control
Basslane Pro
Basslane Pro is a plugin that finely controls low-end stereo width to deliver bass that translates powerfully on any playback system.
Its core function transparently narrows or widens stereo width below a chosen frequency using linear-phase processing. With Mono Recovery, out-of-phase components in wide synth basses — which would normally disappear when summed to mono — are detected and blended back in, so the low-end impact survives mono playback.
Stereo Harmonics keeps the sub band safely mono while spreading only the upper harmonics wide, producing a natural sense of width and presence in the bass. It also includes two Unisum-based multiband dynamics units to tighten the lows or tame the side energy.
Main features
- Stereo width control with switchable linear-phase / zero-latency modes
- Mono Recovery to prevent loss of out-of-phase low end
- Stereo Harmonics for natural low-end stereo image
- Unisum-based multiband dynamics (Side / Stereo modes)
- Analog-style resonant HP filter
Basslane (Free)
Basslane is a simple free plugin that narrows the stereo width below a chosen frequency to pull bass into the center.
It lets you push muddy or overly wide low end — from stacked kicks, basses, delays or reverbs — back to the center with a single knob. With the Side Harmonics feature inherited from Basslane Pro, the sub band stays safely mono while harmonics above it can be sent to the sides for a pseudo wide-bass effect.
Main features
- Variable stereo width narrowing below a chosen frequency
- Side Harmonics for pseudo wide-bass effect
- Built-in stereo balance & correlation meters
- Solo monitoring of filter and Mid/Side
Unisum Mastering Compressor
Unisum is a new-topology mastering compressor that combines transparent sound with fine-grained control.
Internally it is a wideband compressor, but the sidechain uses a 3-band multiband detection scheme with parallel RMS/Peak detectors in each band. This lets you set Threshold, Ratio and Attack/Release per band — e.g. “deep and slow in the lows, light and fast in the highs.”
Attack/Release curves and the linear vs. logarithmic balance of the release are continuously variable. Transient Override changes timing for large transients, Memory Effect emulates opto-style program-dependent behavior, and the HYGGE circuit adds analog character.
Main features
- 3-band multiband detection sidechain (RMS + Peak)
- Frequency-dependent Threshold / Ratio / Attack / Release
- Continuously variable Attack/Release curve and linear-to-log release
- Transient Override, Memory Effect, HYGGE circuit
Kelvin Tone Shaper
Kelvin is a saturator for tone shaping that combines two saturation stages with analog-style EQ.
Its key feature is the ability to freely combine 10 saturation models — Transformer, Tube, Diode and more — across two stages. You can place them in series, parallel or Mid/Side. For example, “Stage 1 adds transformer low-end thickness; Stage 2 runs the highs through tube for color” — that kind of layered processing is possible.
Analog-style shaping filters sit before and after, with Pultec-style passive low and high bands. Sending only the desired frequencies to saturation while shaping the final balance independently means it adapts to delicate mastering and creative sound design alike. Spread adds slight harmonic differences between left and right, De-Fuzz cleans high-end distortion, and a soft clipper tames peaks.
Main features
- Two saturation stages configurable in series / parallel / Mid-Side
- 10 saturation models including Transformer / Tube / Diode
- Tone shaper including Pultec-style passive low/high bands
- Spread for natural stereo, De-Fuzz to clean high-end distortion
- Soft clipper, Auto-Gain and dry/wet control
- 4 quality modes
