The original Turtle Beach MultiSound (now called the "MultiSound Classic") 
was the first truly professional-quality combination audio and MIDI card for 
the IBM-PC/AT and its Industry Standard Architecture ("ISA"). 

The MultiSound Classic debuted in 1992 and went out of production in early
1994. It included a high quality, genuine EMU Proteus 1/XR wavetable 
synthesizer built into the card itself. 

The MultiSound Classic has a 9 pin MIDI connector that can be used with 
an advanced MIDI interface with MIDI IN, MIDI OUT and MIDI THRU female 
connectors for hookup to external synthesizers and MIDI controllers.  

The digital audio section of the card was equally impressive, boasting the 
Motorola 56001 Digital Signal Processor ("DSP") chip, which was capable of 
internal processing in 56-bit resolution, with 24-bit input and output of
audio data.  

This high-resolution internal processing capability was the main reason why 
the MultiSound Classic sounded so much better than its competitors.  
By coupling this DSP power with the Proteus synth and high quality 18-bit 
digital audio converters by Crystal Semiconductors, the Turtle Beach 
MultiSound Classic was indeed a modern-day "classic".
