1. EchoBoy
EchoBoy is Soundtoys’ flagship delay plugin, offering 31 meticulously modeled vintage echo hardware styles. It authentically reproduces legendary delay machines including the EchoPlex tape echo, Roland Space Echo, Electro-Harmonix Memory Man, Roland DM-2 analog delay, and the TelRay oil-can delay. Each style goes beyond approximation — EchoBoy models the unique tape saturation, flutter, frequency response, and timing characteristics of each hardware unit individually. Supported modes include mono, stereo, dual, and rhythm echo, plus a built-in LFO for modulated delay effects. EchoBoy Jr. — a streamlined companion plugin featuring 7 of the most essential hardware styles in a simplified interface — is included at no additional cost.

2. Crystallizer
Crystallizer recreates the iconic Crystal Echoes algorithm from the Eventide H-3000 harmonizer — one of the most distinctive pitch-shifting reverb effects ever built into a hardware unit. The plugin samples incoming audio in real time, pitch-shifts the captured granules, and plays them back in reverse, producing shimmering, ethereal echoes that appear to emerge backward from the mix. Crystallizer is ideal for adding otherworldly textures to guitars, synth pads, and vocals, with controls for pitch shift interval, echo time, feedback amount, and the wet/dry blend between the original and processed signal.

3. FilterFreak
FilterFreak is a rhythmically animated analog filter plugin that models the warmth and character of three classic hardware filter designs: the Minimoog ladder filter, the ARP Filterbank, and the Mu-Tron III envelope follower. What makes FilterFreak unique is its built-in step sequencer, which allows you to program rhythmic filter patterns locked in sync with your DAW’s tempo. The result can range from subtle analog warmth and gentle sweeping to aggressively stuttering rhythmic filter cuts. Both FilterFreak 1 (single filter) and FilterFreak 2 (dual independent filters) are included in your purchase.

4. Decapitator
Decapitator is an analog saturation plugin that models five distinct hardware saturation circuits, each delivering its own character of harmonic distortion and warmth. The five styles are: A (Ampex 350 tube tape machine preamp), E (EMI TG channel strip), N (Neve 1057 input channel), T (Thermionic Culture Vulture with EL34 tubes, capable of intense harmonic saturation), and P (germanium transistor “punish” mode for extreme, musical distortion). Each model responds uniquely to input level with its own frequency coloring, harmonic content, and saturation curve. Additional controls include a Tone knob for high-frequency shaping and a Mix knob for parallel processing.

5. Radiator
Radiator models the tube preamp circuit of the Altec 1567A tube mixer amplifier, a piece of vintage studio hardware from the 1950s used on many iconic recordings of that era. The Altec 1567A adds musical harmonic content and a gentle, frequency-dependent compression when driven, producing thick, full warmth without obvious distortion. Radiator models not just the saturation but also the transformer coloring and subtle frequency response shaping that gives signals a distinct vintage broadcast character. Also included is Little Radiator, a simplified, streamlined version of the plugin for quickly applying tube warmth without detailed adjustments.

6. Little AlterBoy
Little AlterBoy is a vocal pitch and formant shifting plugin built for dramatic transformation of vocal performances. Unlike pitch correction tools, it is designed for intentional, bold shifts — changing the fundamental pitch of a voice while simultaneously shifting the formants (the resonant characteristics of the vocal tract that determine whether a voice sounds male, female, small, or large). This enables convincing gender-shift effects, robotic tones, and wide-ranging creative transformations. Little AlterBoy also supports MIDI input, allowing pitch to be controlled in real time from a keyboard controller or via DAW MIDI automation.

7. SuperPlate
SuperPlate models five iconic plate reverb units, each with unique tonal characteristics derived from its original hardware. The five plates are: EMT 140 (the industry-defining steel plate used on countless major records since the 1960s, known for its full, smooth decay), EMT 240 (a lighter aluminum plate with a brighter, more airy reverb tail), Audicon (an early steel plate with a darker, more complex decay), Stocktronics RX4000 (valued for its dense, musical reverb density), and the EcoPlate III (an American plate reverb celebrated for its warm, transparent sound). All five respond to controls for decay time, pre-delay, tone, and Mix for parallel blending.

8. Devil-Loc Deluxe
Devil-Loc Deluxe is modeled on the Shure Level-Loc, a vintage automatic level control device originally designed for public address systems that became a coveted studio secret weapon for brutally compressed drum sounds. When pushed hard, the Level-Loc produces a distinctive slow-attack, slow-release compression with enormous sustain and heavy pumping character. Devil-Loc Deluxe provides controls for Crush (compression intensity), Crunch (harmonic saturation amount), and a Mix knob for parallel processing. Also included is the original Devil-Loc, a simplified single-knob version for maximum compression with minimal settings.

9. MicroShift
MicroShift recreates the classic ADT (Automatic Double Tracking) stereo widening effect of two sought-after hardware processors: the Eventide H3000 harmonizer and the AMS DMX 15-80s digital delay. Both units created the illusion of doubled vocals and instruments by adding a slightly pitch-shifted, short-delayed copy to the opposite side of the stereo field. The result is a wide, full-sounding image with better mono compatibility than conventional stereo widening approaches. MicroShift offers three hardware style modes with controls for tuning offset and stereo width. Included is Little MicroShift, a simplified single-knob version for quick stereo enhancement.

10. Tremolator
Tremolator models the organic, warm character of vintage hardware tremolo circuits. It captures the distinctive tremolo sound of the Fender Vibrolux amplifier and the Wurlitzer electric piano, reproducing their specific waveshape, bias, and speed characteristics that give vintage tremolo its musical, human quality. Beyond simple tremolo, Tremolator features a built-in rhythm editor that lets you program complex, syncopated tremolo patterns in sync with your DAW’s tempo — enabling everything from smooth, rounded tremolo to hard-gated, stuttering volume patterns with step-sequencer-style control.

11. PanMan
PanMan recreates the behavior of classic hardware autopanning boxes used in professional recording studios during the 1960s and 1970s, which swept audio signals across the stereo field in rhythmic, musical patterns. PanMan provides detailed control over panning speed, stereo width, waveform shape (sine, triangle, square, and sample-and-hold random), and DAW tempo synchronization. It can produce everything from gentle, floating stereo movement to precisely timed, hard-cutting rhythmic panning effects that behave like a dedicated stereo autopanning step sequencer.
12. PrimalTap
PrimalTap models the 1978 Lexicon Prime Time, one of the earliest digital delay units manufactured for professional studio use. The Prime Time was limited in audio bandwidth and dynamic range by modern standards, giving it a lo-fi, slightly degraded character that adds vintage texture and grit to signals. PrimalTap precisely models these hardware limitations, including its frequency response characteristics and gentle saturation. Key features include a Freeze function that captures and loops incoming audio indefinitely, and a Multiply mode that doubles delay time while slowing playback speed for a pitch-down tape-stop effect. Included is Little PrimalTap, a simplified single-knob version.

13. Sie-Q
Sie-Q is an equalizer plugin modeled on the Siemens W295b, a passive equalizer module from the Siemens W89 broadcast console widely used in European recording studios and broadcast facilities throughout the 1970s and 1980s. The W295b is known for its particularly gentle, musical EQ curves that shape frequency content in a natural, transparent manner. Beyond its EQ behavior, the Siemens circuit adds subtle harmonic coloring even when no EQ is actively engaged, lending signals a distinctly warm, vintage European broadcast character — ideal for vocals, acoustic instruments, and mix bus processing.
14. PhaseMistress
PhaseMistress models 69 different hardware phaser styles with adjustable stage counts from 2 to 24 stages, covering everything from subtle chorus-like shimmer to deep, multi-stage swirling phasing. Among the hardware references are the Bi-Phase (the legendary dual-channel phaser beloved for its complex, lush sound), the MXR Phase 90 (the iconic orange stompbox famously used by Eddie Van Halen), and the Electro-Harmonix Small Stone (celebrated for its rich, warm phasing tone). PhaseMistress offers a built-in step sequencer for rhythmic phasing patterns, envelope following, and manual mode for sweep automation via DAW automation.

15. SpaceBlender
SpaceBlender is a non-linear experimental reverb plugin that creates cinematic, evolving spaces far beyond the behavior of any natural room, plate, or spring reverb. Rather than reproducing acoustic physics, SpaceBlender generates complex, morphing reverb textures — atmospheric washes, swells, builds, and diffuse otherworldly spaces that function as sound design tools as much as reverb processors. SpaceBlender suits cinematic music production, ambient and experimental electronic music, sound design for film and video games, and any context where the goal is to transform audio into an expansive, immersive soundscape.
