The headline this week is Rupert Neve Designs, which released their first-ever native software plugins on September 17. Three of them, developed in collaboration with McDSP. By September 18 two had been pulled from the store after audio errors were found in the release builds. The 551 Inductor EQ remains available. The Portico II Master Buss Processor and 542 Tape Emulator are in retesting. A bumpy debut, though the underlying hardware these emulations model has earned more hits records than almost any other gear in professional audio.
Alongside that story: a physics-based console DAC emulator based on the PlayStation One, a spectral morphing engine with genuine algorithm choice, a three-band autopanner with per-band modulation, and a growl designer for bass producers.
551 Inductor EQ, Rupert Neve Designs
$129, iLok required, AAX / AU / VST3, Mac and Windows
The 551 Inductor EQ is a three-band equalizer modeled on Neve's original 500 Series hardware design. The 500 Series format was introduced in the late 1960s as a modular system for consoles, and the 551 hardware module was designed by Rupert Neve and introduced in 2014. The plugin was developed with McDSP, who have built hardware-modeled plugins for SSL, API, and Neve-adjacent products for years.
This is the only plugin from Rupert Neve Designs' debut trio currently available for purchase. The Portico II Master Buss Processor ($199) and the 542 Tape Emulator ($129) were removed from the store on September 18 after audio errors were discovered in their release builds. The company is retesting both and will notify customers who already purchased when updated builds are ready.
The 551 itself is the straightforward entry point: a hardware-accurate EQ from the console lineage that shaped the sound of recording studios for five decades. If you have been waiting for RND to release plugins under their own name, they have now. Two of three had a rough landing, but the 551 survived.
For whom: engineers already working in the Neve-adjacent hardware tradition who want a matching plugin, and anyone mixing in Pro Tools with AAX who needs a properly modeled Neve EQ.
Grey Matter, Mixland
$29 intro (regular $49.99), no iLok, Mac and Windows, 14-day free trial
Grey Matter is a saturation plugin modeled on the DAC circuitry inside the Sony PlayStation One. The modeling approach is physics-based rather than static transfer-curve based: the plugin runs real-time simulation of molecular physics, component strain, and thermal load within the circuit model. As you push it harder, those physical properties change, and the response changes with them.
The Sony PS1 DAC used a delta-sigma converter design running at 44.1 kHz with limited dynamic range by modern standards. That particular flavor of converter distortion became associated with lo-fi textures once producers started sampling through it deliberately. Grey Matter takes that circuitry and builds a sandbox around it: an interactive circuit view where component behaviors can be adjusted, pushing the emulation from subtle analog character into harder nonlinear territory.
At $29.99 intro the argument is easy, and the free trial removes the risk. The interaction model, where you are adjusting physics parameters rather than gain knobs, gives it a character that generic saturation plugins do not.
For whom: producers working with lo-fi aesthetics, sound designers who want a saturation plugin with unusual and physically consistent behavior, and anyone curious what PS1 DAC circuitry actually sounds like when pushed.
GRRR, Thenatan
$12 intro (72-hour launch price from Sept 19, ends Sept 22) / $49 regular, VST3 / AU, Mac and Windows
GRRR is a growl designer built around four processing engines. TRASH handles wavefolding, decimation, and ring modulation on a single knob. TALK is a beat-driven formant filter that responds to transients and shapes vowel movement, accelerating up to 4x on hits. WUB is a resonant filter sweep with extended range. SCREECH adds a metallic high-frequency laser sweep from low to high end.
The defining behavior is beat-reactivity: all four engines respond to the dynamics of the incoming signal rather than being purely manual. The plugin listens to the track's transient content and modulates its processing based on where hits land. The result sits somewhere between a multiband distortion, a vocoder filter, and a sidechain-driven processor.
GRRR is clearly aimed at bass producers in dubstep, riddim, trap, and drill, and it makes no pretense of being subtle. If you are working in those genres and need something that reacts aggressively to your bass or drums, this does that. If you need anything with restraint, look elsewhere.
The 72-hour intro price from September 19 puts the current price at $12. At that price, the risk of trying it is essentially zero.
For whom: bass music producers who want beat-reactive growl and formant effects without building the same result from four separate plugins.
Orbit, SoundGhost
$29 intro (regular $39, intro ends September 30), AU / VST3, Mac and Windows, no AAX
Orbit splits an incoming signal into three frequency bands, Low, Mid, and High, with adjustable crossover points, and applies independent modulation to each. Per band, you can control pan position, width, and volume, each with its own LFO shape chosen from nine waveforms including an envelope follower. Rates run tempo-synced or free, and a one-click randomization button generates starting configurations.
The three-band approach is what separates Orbit from standard autopanners. A conventional autopan moves the entire signal in stereo. Orbit can keep the low end anchored to center while the mids and highs drift independently, or push the mid frequencies into a pattern triggered by the signal's own dynamics. The mono correlation meter is a useful addition since aggressive stereo processing of this kind can cause mono compatibility problems.
The plugin does not support AAX. Pro Tools users are out for now.
For whom: mixers and producers who want movement and width in their tracks without committing the entire signal to a single panning pattern. Useful for synth pads, guitars, and any source where per-band stereo treatment would create interest that a single-band autopan would not.
Spectra, blepfx (indie pick)
$25, VST3 / AU / CLAP, Mac, Windows, and Linux
Spectra is a spectral morphing plugin that splits two audio signals into their envelope and harmonic components, then merges them. Feed a sidechain signal and Spectra extracts its spectral envelope while preserving the harmonic character of the main signal, or vice versa. The result is a new timbre that belongs fully to neither source.
The plugin ships with four extraction algorithms, each with distinct behavior. Linear is FFT-based and clean but introduces some pre-ringing at transients. Hilbert applies the Hilbert transform to reduce that pre-ringing while staying in the FFT domain. LPC (linear predictive coding) comes from speech processing and produces its own character with minimal pre-ringing. IIR uses traditional vocoder bandpass filter banks and runs with zero latency, which matters if you are using it in a live or low-latency context.
Beyond the morphing core, Spectra includes a polyphonic formant shifter with a range of 24 semitones in either direction and a tilt filter for broad spectral shaping.
CLAP and native Linux support at $25 makes this notable for the platform coverage alone. The algorithm selection gives experienced users genuine control over the morphing character. It is not a plugin with a single clearly defined use, but for spectral design work or unusual vocoding effects it covers ground that most competitors either charge more for or only partially address.
For whom: sound designers working with spectral processing, producers who want formant shifting with sidechain morphing, and Linux users with limited options in this category.
Five this week. If you are on a deadline: GRRR's $12 intro ends September 22. Grey Matter's intro price has no stated end date but is listed as promotional. Orbit's intro runs until September 30. RND's Portico II MBP and 542 Tape Emulator will be re-released once the audio bugs are resolved.
