The String Concerto II by G-Storm Plugins is a software synthesizer designed to recreate the classic sound of vintage string ensembles, inspired by the Logan String Melody II. Unlike sample-based instruments, it uses advanced synthesis methods combined with a unique triple-delay line ensemble effect to deliver rich, authentic tones. This approach ensures a dynamic and expressive string sound that captures the warmth and character of traditional string machines.

This plugin features fully polyphonic bass and treble sections, each offering distinct cello, viola, and violin voices. Users can blend these sections to produce anything from lush full orchestra textures to focused solo string sounds. The bass section includes a monophonic low instrument with priority for lower octaves, adding depth and foundation. Separate attack and release envelope controls for both bass and treble sections provide nuanced articulation and control over the sound's dynamics.

String Concerto II offers three ensemble modes that range from subtle to full orchestral effects, enhancing the string textures with selectable stereo widening for a spacious and immersive soundstage. This stereo feature creates a rich panorama that surpasses the original instrument's mono output, making it ideal for modern productions. The interface includes intuitive controls with responsive sliders and potentiometers, allowing precise adjustments to tailor the sound to any musical context.
