Imagine is a software synthesizer developed by Expressive E in collaboration with Applied Acoustic Systems. It uses physical modeling synthesis, a method that simulates how sound is produced by real-world instruments such as strings, bars, tubes, and membranes.

This approach allows producers and sound designers to build sounds that feel natural and dynamic while still offering the flexibility of electronic synthesis.

At the heart of Imagine are two instrument layers. Each layer can model different resonant materials and combine them with various excitation methods. This layered design gives users the ability to craft complex textures and evolving tones.

How the Sound Engine Works
Imagine’s sound generation starts with something called an Excitator. This element represents the action that triggers sound in a real instrument, such as striking a drum or plucking a string.

There are three main excitation types:

• Mallet – simulates hitting a surface or resonant body

• Noise – uses noise signals to excite resonators

• Sequencer – creates rhythmic or repeating excitation patterns

Once the sound is triggered, it passes through modeled resonant structures such as bars, strings, skins, or tubes. By adjusting parameters like position, brightness, and damping, users can drastically change the resulting tone.

The combination of exciters and resonators forms the core of Imagine’s expressive sound design capabilities.

Presets and Sound Design Potential
Imagine ships with hundreds of presets, giving users immediate access to a wide range of tones—from soft ambient textures to complex percussive sounds.

But the real strength of the plugin lies in experimentation. Producers can mix two instrument layers, tweak excitation parameters, and apply modulation to create entirely new sounds.

Because the system is based on physical modeling rather than static samples, the resulting sounds often feel more organic and dynamic.

Modulation and Effects
Beyond its modeling engine, Imagine includes powerful modulation tools that allow for deeper sound sculpting.

Key features include:

• Multi-stage envelope generators (MSEG)

• Advanced modulation routing

• Macro controls for quick adjustments

• Built-in effects processing

These tools allow producers to create evolving soundscapes, cinematic textures, and expressive instruments that respond dynamically to performance.
