EastWest String Machine — Free Download
String Machine is a virtual instrument that samples classic vintage string synthesizers, layering them with acoustic strings, brass, woodwinds, and vocals for unique retro-modern pads.

Vintage-Inspired Hybrid Design
String Machine draws from iconic hardware units of the past, including the Arp Solina, Oberheim OBX, Roland RS-505, and Jupiter 6. This virtual instrument captures the distinct character of these vintage synthesizers and combines them with modern acoustic instrument samples. The result is a versatile hybrid tool for creating rich, layered pads that evoke a strong sense of nostalgia while remaining suitable for contemporary production.
The sound engine is organized into four color-coded sections: string machines and pads, string sections, solo woodwinds and brass, and choirs and solo vocals. Each section offers multiple instruments and variations, allowing you to blend electronic and acoustic timbres flexibly.
Ensemble Chorus and Interface
A hallmark of vintage string machines is their ensemble chorus effect, which adds thickness and movement. The built-in ensemble chorus in String Machine features three distinct modes, modeled after the Arp Solina, Roland VP-330, and a modern transparent mode. Each mode imparts a different character—from warm, saturated thickness to clean, spacious width—allowing you to shape the final sound to fit your mix.
The user interface reflects the design of its hardware predecessors, with chunky instrument switches, envelope sliders, and push buttons that mimic the tactile feel of original units. This design is not just cosmetic; it streamlines workflow by keeping key parameters accessible and intuitive. The interface’s layout encourages hands-on exploration, whether you are adjusting envelope attack or switching between instrument groups, making it easy to craft sounds without navigating complex menus.
Presets and Custom Sound Design
The instrument comes with a set of presets programmed by Nick Phoenix, which showcase the range of sounds possible—from dreamy retro pads to lush string backdrops. These presets serve as a starting point, demonstrating how to combine the various instrument sections effectively. However, the intended use is to create your own presets, exploring the vast combination space offered by the hybrid engine.
Because every section can be independently mixed, you can quickly prototype ideas by layering a vintage synth pad with a solo flute or choir, then adjust envelopes and the ensemble effect to tailor the sound. This flexibility empowers producers to go beyond presets, crafting textures that are uniquely suited to each track. The process is straightforward: choose instruments, adjust their levels, and tweak the ensemble chorus to taste.
Genre Applications and Practical Use
String Machine is designed for music that thrives on retro nostalgia, such as chillwave and pop, but its hybrid nature makes it suitable for a broad range of genres. It excels at providing large but clear ensemble string pads that sit well in a mix without overwhelming other elements. For electronic music producers, layering the vintage synth sections with acoustic strings can add depth and human feel.
In practice, you might use String Machine as a background pad in a pop ballad, or as a lead texture in a synthwave track. The ability to blend electronic and acoustic sources means it can fill a range of roles, from subtle atmospheric layers to prominent melodic elements.
