This week's releases lean toward unusual control schemes: pressure-state dynamics, four-axis filter morphing, level-matched width adjustments, and a boutique reverb amp with cabinet impulse responses across 19 microphone positions. One real session drummer, no filler.
MixWave Benson Monarch Collection ($129 intro / $179 regular)
Benson Amps is a small Portland-based boutique builder whose Monarch combo amp is best known for an unusually clean-to-saturated harmonic curve and an integrated spring reverb that has become a cult tool in indie rock and ambient guitar. MixWave's component-modeled emulation of the Monarch lands this week, paired with a separate set of pedals from Benson's lineup: the Florist preamp/overdrive, the Delay, the Tall Bird reverb pedal, two Germanium dirt pedals (Boost and Fuzz), and a clean Preamp.
The element that distinguishes this from a typical guitar plugin is the cabinet module. MixWave captured the Monarch's 1×12 cabinet across 19 microphone positions, including close, far, and room placements with several mic types. Nineteen positions in a single cabinet impulse response library is unusually deep, and it matters because microphone placement on a 1×12 changes the perceived high-frequency content more than the amp's EQ controls do. Being able to switch between an SM57 on the cone and a ribbon mic in the room without committing to a re-record gives you tonal options that a single fixed IR doesn't.
Component modeling here means the plugin simulates the circuit behavior of each stage rather than capturing a static profile of the amp at one setting. The practical difference shows up when you ride the Volume knob: a profiling-based capture sounds the same at every gain level (it can only reproduce what was sampled), while component modeling responds to input level the way the analog circuit does, which on a Monarch means the integrated spring reverb starts to break up before the preamp does, an inversion of the usual order in tube amps.
VST3, AU, AAX on macOS and Windows. Requires an iLok account. The full collection is $129 during the intro period.
Good for: Guitar recording where you want a specific boutique character without acquiring the hardware. Also useful for re-amping synths or processed material that benefits from the Monarch's particular saturation curve. Less relevant if you're after generic Marshall or Fender territory, this is a specific voice.

Mastering The Mix Stereovault ($80)
Stereo widening is one of the easiest things to get wrong because the immediate sensation of "bigger" is largely loudness. Tilt the M/S balance toward the sides and the perceived loudness goes up, the center starts to thin out, and the low end loses focus, but the first sensation overwrites the latter problems unless you A/B with matched levels.
Stereovault's central design choice is to compensate for every adjustment with what Mastering The Mix calls Level Match. When you change the width, the plugin renormalizes the output level so the loudness difference is removed from the comparison. You're then judging the actual stereo change rather than the loudness illusion that usually accompanies width changes. This is the same idea behind the "level-matched A/B" workflow that mastering engineers use manually, built into the adjustment loop.
The plugin runs six modules: Spread (three different widening algorithms: Pristine M/S, Diffuse allpass-based, and Vintage pseudo-stereo), Creative (Haas, Chorus, Flux, Space, Stretch movement effects), Panorama (frequency-specific panning), Width (M/S energy redistribution), Rotate (stereo repositioning that isn't conventional panning), and Clean (corrective EQ on mid or side independently). Reference track import generates a preset based on the reference's stereo profile, which gives you an objective starting point rather than guessing at "how wide should this be."
The three widening algorithms are not interchangeable. Pristine M/S is a strict mid/side gain split, phase-coherent, mono-safe if you watch the side level. Diffuse runs allpass filters that introduce frequency-dependent phase decorrelation, which produces a wider image but starts to comb-filter when summed to mono. Vintage pseudo-stereo uses Haas-style short delays to create width from a mono source. Knowing which one you're using changes how confidently you can summon mono.
VST3, AU, AAX on macOS and Windows. 15-day free trial, no credit card. Through June 3, purchases include one free plugin from the Mastering The Mix catalog.
Good for: Mix bus and master bus stereo work, especially when streaming destinations demand mono compatibility. The Level Match feature alone justifies the price for engineers who haven't built a manual matched-A/B habit.
Toontrack Drumology EZX ($89)
Drumology is a Superior Drummer 3 and EZdrummer 3 expansion that captures four kit configurations across four decades of pop and rock production: a 1960s setup, a 1970s setup, a 1980s setup, and a 1990s setup, each recorded with period-appropriate microphone choices, room treatment, and processing chains. The recordings were done at Livingston Studios in London with Jeremy Stacey behind the kit (Sheryl Crow, Robbie Williams, Sia, King Crimson) and Paul Stacey engineering.
The era framing is more useful than it sounds at first because drum sound across decades is not just about the kit, it's the combination of kit, room, microphone selection, and tape (or lack of) that defines a period sound. A 1970s kit recorded with 2026 microphones into a 2026 console sounds like neither the 1970s nor the 2020s. Drumology approaches each era as a complete signal chain, which is closer to how a record from that era was actually constructed.
For users who already own Superior Drummer 3, the value calculation is whether the era-specific kits cover ground you don't already have. The included rooms and processing presets matter more than the kits in isolation, because the kits can be played back through Superior Drummer 3's existing routing, but the recorded room ambience is fixed at capture time.
Available for EZdrummer 3 and Superior Drummer 3 through Toontrack's installer.
Good for: Producers working on retro-styled productions who want period-correct drum sounds without sourcing era-specific gear. Also useful as a reference set for engineers trying to understand how drum recording aesthetics changed across decades. Less essential if you only need one specific era, you're paying for all four.
Rob Papen FilterField ($39 intro / $49 regular)
FilterField is a four-filter effect with an XY morphing pad that smoothly blends between the filter states rather than crossfading between them. Each of the four filter modules can independently use any of 32 analogue-modeled filter types, high-pass, low-pass, band-pass, notch, comb, formant, and variations of each with different slopes and resonance behaviors. The XY pad sits between them: a position in 2D space defines a weighted combination of all four filters, and moving across the pad continuously deforms the resulting frequency response.
Two routing modes change what that combination means in practice. In parallel mode, the four filters operate side-by-side and the XY position controls their relative mix levels, so the result is a sum of four parallel filter outputs. In serial mode, the four filters are chained, and the XY position controls how each contributes to the cascade, moving across the pad is closer to repositioning resonant peaks within a single overall filter response than to crossfading separate processors.
The XY movement can be recorded as a path and played back at tempo-locked rates with various beat divisions, which is the part that turns this from a static effect into a modulation source. A recorded XY path is effectively a multi-parameter LFO with shapes that you draw by hand, synced to host tempo. Drawing a circular path produces continuous filter sweeps; drawing sharp corners produces stepped filter changes; the recording resolution determines smoothness.
VST/VST3, AU, AAX on macOS and Windows. Intro $39 until May 31. Also bundled in the new eXplorer-11 collection alongside RAW-Kick 2.
Good for: Sound design and electronic production where filter movement is part of the musical content. The hand-drawn XY paths fill a niche between fixed LFO shapes and full envelope-following modulation matrices.
Unusable Engineering Spectral Pressure Chamber (~$59) (Indie Pick)
Unusable Engineering launched a series of "science-native" plugins this past week, each built around a different physics or systems model rather than the usual DSP topology. Spectral Pressure Chamber is the multiband dynamics processor from that series, and its control model is genuinely different from a standard multiband compressor.
The plugin tracks spectral energy across three bands (low, mid, high) and accumulates it as "pressure" inside three connected chambers on a shared membrane. Pressure builds when signal energy enters a chamber, leaks out over time (the equivalent of release behavior), and spreads between chambers across the membrane (which couples band behavior in a way standard multiband splits don't). The current pressure state, not the instantaneous level, becomes the control signal that drives compression in each band.
The practical consequence is that the processor reacts to sustained spectral content differently than to transients of the same peak level. A short loud transient briefly raises pressure but doesn't fill the chamber; a longer note at lower peak level can fill the chamber further because it has time to accumulate. This is closer to how perceived density works for the ear than to how a level detector works, and it means the same input peak level in two different contexts can produce different gain reduction. Whether this is desirable depends on the source, for sustained material like pads and vocals it tends to be more musical than threshold-per-band; for percussive material it can feel sluggish unless you tune the pressure release fast.
The visual interface shows the three chambers and the membrane motion in real time, which is unusual but earned: the simulation drives the processing, so watching the chamber state is watching what's affecting the audio. The wider series (Cavitation Fractures distortion, Frequency Guillotine spectral gate, Ensemble Diffuser, Tension Reactor reverb, Entropy Encoder codec degradation) shares the same engine philosophy across different physical models.
VST3 and AU on macOS. Pricing reported in the $59 range per plugin.
Good for: Engineers and sound designers who want dynamics behavior that responds to perceived density rather than instantaneous peaks. Particularly useful on sustained material where conventional multiband compression feels overly reactive to transient detail. If you only ever reach for a multiband to control sibilance or kick transients, the pressure model is overkill and the standard tools are faster.
