Expanse-5 (XP-5) is a deeply expressive virtual analog synthesizer born from Acustica’s groundbreaking MAREA series. Available in VST3, AU, and AAX formats, XP-5 faithfully captures the soul of a legendary, five-voice polysynth of the late analog era—celebrated for its rich tone, musical flexibility, and iconic presence in countless recordings.

Faithful to the principles of classic subtractive synthesis, XP-5 captures the essence of that era while pushing the boundaries with modern enhancements. From an oversampled, high-resolution architecture to advanced modulation and spatial features, XP-5 blends vintage character with cutting-edge digital precision—offering a timeless sound redesigned for today’s creative workflows.

At its core lies MUST (Modular Unified Synthesis Technology), Acustica’s proprietary engine designed to deliver ultra-low latency, efficient CPU usage, and pristine audio quality. This cutting-edge architecture ensures that XP-5 delivers not just authenticity, but also the reliability and flexibility demanded by today’s music producers and sound designers.

Why Oversample Everything?

Running the entire signal chain at oversample rate delivers tangible sonic benefits:

Extreme detail and transients, ideal for sharp percussive sounds and fast envelopes.
Clean modulation and PWM, free of stepping, zipper noise, or aliasing.
Consistent phase behavior, crucial for stereo imaging and analog-style motion.

This architecture allows XP-5 to preserve the sonic integrity of its analog inspiration while offering far greater resolution and responsiveness. This minimizes aliasing, enhances transient clarity, and enables smooth, analog-like modulation across the entire signal chain.

Power at a glance

MUST-Powered Engine
Hybrid synthesis core combining convolution and analog-style modeling.
Full Oversampled Architecture
Entire signal path runs at high internal rates—no block processing, resulting in cleaner sound, smoother modulation, and minimal aliasing.
Scalable Polyphony
Polyphony ranges from 2 to 10 voices, starting with 5 by default—just like the original. Superstereo takes it further by expanding the voice field for a wider, fuller sound.
Dual Oscillators
With cross-mod, sync, PWM, noise, and fine detune.
Multimode Filters & VCA
Classic subtractive behavior with envelope, key follow, and velocity control.
Superstereo & Age
Adds stereo depth and analog imperfection with adjustable drift.
Advanced Modulation
Fast envelopes, audio-rate LFOs, and intuitive routing.
Studio-Grade Effects
Includes chorus, delay, reverb, EQ, and a powerful multiband saturator.
Performance Toolkit
Real-time MIDI learn, portamento, arpeggiator, and visual feedback.
450+ Pro Presets
Curated by sound designers, producers, and musicians
