Applied Acoustics The Integral — Free Download
The Integral is a complete virtual instrument and effect collection from Applied Acoustics Systems, featuring physical modeling synths, electric pianos, and creative effects for music production.

Complete Collection Overview
The Integral bundles the entire Applied Acoustics Systems product line into one package, offering a comprehensive toolkit for musicians and producers. It includes the physical modeling instruments Chromaphone, Strum, Ultra Analog, String Studio, and Lounge Lizard, plus the creative Objeq Delay effect and all AAS sound banks. This collection covers a wide range of sonic possibilities, from acoustic emulations to futuristic synthesizer sounds.
The collection is designed for those who want a full suite of instruments without needing to purchase each separately. With a range of synths, electric pianos, and guitar models, it suits genres from pop and rock to electronic and experimental music. The included sound banks provide instant presets, while the instruments themselves offer deep editing, making this a versatile addition to any producer’s toolkit.
Key Instruments and Synthesis
At the heart of the collection is a series of advanced physical modeling synthesizers. Chromaphone allows users to create percussive and melodic instruments by combining resonators like membranes, bars, and strings. Strum offers both acoustic and electric guitar models with features like strumming keys, slides, and bends, translating keyboard performance into realistic guitar playing.
Ultra Analog provides a virtual analog synthesizer with smooth oscillators, a range of filters, and built-in effects. Lounge Lizard faithfully recreates classic electric piano sounds, preserving the tone and feel of the originals. Objeq Delay is a unique effect that uses acoustic models to shape the input signal with resonances from plates, beams, drumheads, and strings, then applies filters and delay to create rhythmic patterns.
Features and User Experience
Each instrument in the collection is built on Applied Acoustics’ physical modeling technology, which aims for expressiveness and responsivity. The interfaces are generally designed to be simple and logical, with one-screen layouts for easy navigation. For example, Ultra Analog features a single-screen interface with an arpeggiator, loopable envelopes, and effects, while other instruments offer similar streamlined controls. This makes them accessible to both beginners and advanced users.
The collection includes a large number of sound banks, which cover a wide range of styles including ambient, cinematic, electronic, and experimental sounds. These presets allow quick inspiration and are easily tweaked to fit specific tracks. The instruments also support detailed customization, with parameters for material, tuning, coupling, and more. This flexibility ensures that the collection can grow with the user’s needs, from simple preset browsing to deep sound design.
Workflow and Applications
The Integral is well-suited for music production, scoring, and sound design. In a typical workflow, a producer might start with a preset from one of the many sound banks, then modify parameters to fit the mix. For guitars, Strum’s strumming keys and articulation features make it easy to create realistic guitar tracks from a keyboard.
Objeq Delay can be used as an insert or send effect to add movement and acoustic character to any sound. The integrated effects, such as chorus, delay, and reverb in Ultra Analog, reduce the need for external processing. With its breadth of instruments, this collection can serve as a primary sound source for a project, covering chords, leads, basses, and effects.
