In 1990, Young Chang purchased Kurzweil Music Systems, a maker of high end electronic and digital musical instruments.
Joseph Pramberger, a former vice president from Steinway & Sons (head of manufacturing) and an experienced piano designer, joined the company in 1995. Pramberger brought many innovations to piano design, including the “Platinum Touch Action” and the patented asymmetrically tapered soundboard. The Pramberger Platinum series, introduced in 2001, was Young Chang’s top-of-the-line for three years. These models incorporated some German materials including Renner action parts. Joseph Pramberger died in 2003, and the following year, his estate sold the Pramberger name to Samick, but his patents and innovations are still exclusive to Young Chang.
