The Yamaha VL1-m is a digital synthesizer that was released in 1994. It was the first virtual acoustic instrument and was designed to emulate the sound of acoustic instruments such as the piano, strings, brass, and woodwinds. It was also the first instrument to use physical modeling technology, which allowed it to accurately reproduce the sound of acoustic instruments. The VL1-m was used by many famous musicians, including Herbie Hancock, Chick Corea, and Pat Metheny.
