This week brought some serious innovation in plugin development, from advanced filter morphing to perceptually-tuned multiband compression. Here are five releases that caught our attention.
Rob Papen FilterField - $39 (Intro) / $49 (Regular)
Rob Papen's latest release combines four configurable filters with their signature XY morphing control. FilterField offers 32 analog-modeled filter types including comb, vowel, EQ, all-pass, and phaser filters, plus specialized modes like ring modulation, amplitude modulation, and frequency shift.
The XY field enables seamless morphing between the four filter configurations in real-time, creating complex evolving textures that would be impossible with static filter settings. A distortion module with 21 saturation types can be applied pre or post filtering for additional character.
The $39 intro price runs until May 31st, making this an accessible entry point into Rob Papen's filter design expertise. Available for Windows and macOS in VST/VST3, AU, and AAX formats.
KERN Audio PUSH - $29 (Individual) / $59 (Bundle)
KERN Audio's fifth plugin takes a fresh approach to multiband dynamics processing. Instead of traditional four-band crossovers, PUSH operates across 40 ERB (Equivalent Rectangular Bandwidth) frequency bands that match how your ear actually resolves frequency content.
The plugin offers three compression characters: SETTLE, TIGHT, and DRIFT, each providing different spectral shaping approaches. The company positions PUSH as "the step before your compressor," designed to prepare material for final compression rather than replace it.
PUSH maintains phase-coherent processing across all 40 bands simultaneously, avoiding the phase artifacts common in traditional multiband processors. Available individually for $29 or as part of the KERN Bundle for $59 (intro price through May 25th).
Universal Audio Enigmatic '82 Overdrive Special Amp - $49 (Intro) / $99 (Regular)
Universal Audio modeled the legendary D-style Overdrive Special amplifier, known for its singing lead tones and touch-sensitive dynamic response. The plugin captures the amp's distinctive midrange character and harmonic saturation prized for expressive blues-rock and fusion lead tones.
The modeling includes the amp's complete signal path from input to speaker cabinet, with adjustable gain, EQ, and master volume controls. UA's proprietary Unison technology ensures proper input impedance matching when used with Apollo interfaces.
The $49 intro price (50% off) runs through May 25th. The plugin is also included in UAD Spark subscriptions, making it accessible to users already in the UA ecosystem.

Mastering The Mix STEREOVAULT - $80
Mastering The Mix addresses the perennial problem of stereo widening that sounds impressive in solo but weakens mixes in context. STEREOVAULT provides instrument-specific and genre-specific starting points across four width settings: Focused, Balanced, Wide, and Super Wide.
The plugin prevents the common issues with stereo widening: weakened low-end, blurred center imaging, and phase problems that hurt mono compatibility. Instead of generic widening algorithms, STEREOVAULT tailors its approach based on source material type.
A launch promotion offers one free Mastering The Mix plugin with purchase through June 3rd. A 15-day free trial is available with no credit card required.
BLEASS Spectral Resonator - $59 (Intro) / $79 (Regular)
This French developer's latest plugin transforms audio into up to 256 playable harmonics in the spectral domain. Unlike traditional pitch shifters or harmonizers, Spectral Resonator analyzes the frequency content and creates controllable harmonic layers that respond to the input signal's characteristics.
The plugin enables spectral manipulation including frequency shifting, blurring, and destructuring effects. Each harmonic can decay independently, creating complex evolving textures from simple source material. The spectral approach works particularly well on vocals, synthesizers, and percussive elements.
The desktop version intro price of $59 runs until June 1st. BLEASS also offers an iOS version for $14.99, maintaining feature parity across platforms.
Looking Ahead
These releases showcase different approaches to familiar problems: filter morphing, multiband dynamics, amp modeling, stereo imaging, and spectral processing. The trend toward perceptually-informed design (KERN's ERB bands) and source-specific optimization (STEREOVAULT's instrument presets) suggests developers are moving beyond one-size-fits-all approaches.
Next week's roundup will cover any Memorial Day releases and preview the summer plugin season typically announced at NAMM's satellite events.
