This product was called 'MultiSound.' The MultiSound product competed with more established products of the day from Advanced Gravis (now defunct), Adlib (now defunct), Creative Labs, and Media Vision (now defunct).

This card used high quality A/D and D/A, a high quality synthesizer from eMu, and an onboard DSP chip. In 1990, Turtle Beach began developing its first PC sound card. The 56K system was popular among radio stations and mastering studios because it replayed exactly the same digital stream that it recorded. It was based on a Motorola 56000 DSP chip, and offered non linear playlist editing of stereo audio files. Among the first of its kind, the product was named the '56K digital recording system' and was released in 1990. In 1988, Turtle Beach began to work on developing its first hardware product, a hard disk based audio editing system. The SampleVision series was among the first to offer a Macintosh-like user experience on the PC (which at that time did not have Microsoft Windows to provide its GUI). They retooled their product into 'SampleVision', which initially supported the Akai S900, but was designed with an extensible framework, allowing other samplers to be supported. Over the following years, the company developed a few other programs that supported Ensoniq equipment but realized that they needed to develop more generalized products. Ensoniq decided to resell Vision through their dealer network and Turtle Beach Softworks became a profitable company. The software, called 'Vision', connected the Mirage to a PC and used the PC's screen and graphics to make the programming and editing of sounds much easier. The Mirage was the first low cost sampling device that allowed musicians to play realistic choirs, pianos, horns, and other instruments in their performances. The company's first product was a graphical editing system that supported the breakthrough Ensoniq Mirage sampling keyboard. Turtle Beach was founded in 1985 as 'Turtle Beach Softworks' by co-founders Roy Smith and Robert Hoke. In 1995, the company merged with Voyetra, a company that made custom software for sound cards, to form Voyetra Turtle Beach Inc which is headquartered in Valhalla, New York, USA. Turtle Beach Systems is a sound card and headset manufacturer and direct competitor with Creative Labs-branded Sound Blaster.
