Soundscape S-2000 was Ensoniq's first direct foray into the PC sound card market. The card arrived on the market in 1994. It is a full-length ISA digital audio and sample-based synthesis device, equipped with a 2 MiB Ensoniq-built ROM-based patch set. Some OEM versions of the card feature a smaller 1 MiB patch set. It was praised for its then-high quality music synthesis and sound output, high compatibility and good software support.
Ensoniq advertisements for the Soundscape stated "Finally, A Sound Card from a company that knows sound!", claiming that "the same wavetable technology that drives our $3,000 keyboards is available for your PC". [1] The card uses an 'OTTO' synthesizer chip with a companion 'Sequoia' chip for MIDI duties, along with a Motorola 68EC000 8 MHz controller (a low-cost variant of the ubiquitous 68000 with selectable bus width [2] ) and a small amount of RAM. Although it has RAM, the card does not support uploading of sound samples for the synthesizer. The on-board coprocessor was a much-advertised feature of the card, marketed to reduce the overhead of music synthesis through the device. Digital-to-analog audio conversion was handled by an Analog Devices CODEC such as the AD1848, which was capable of sampling at up to 48 kHz. [3] The Soundscape S-2000's sample-based synthesizer lacked an effects processor, meaning digital effects such as reverb and chorus were not supported.
Advertisements also mentioned the card's three CD-ROM interface connectors. [1] As was common with multimedia cards produced in the mid-90s, a variety of proprietary interfaces were supported. This was necessary as ATAPI IDE CD-ROM drives were not yet common, and the majority of optical drives produced required one of the many proprietary interfaces that were prevalent at the time. In addition, the majority of PCs purchased typically had only a single IDE channel, which might already be controlling two hard drives or a hard drive and a tape/disc backup device, so offering additional CD-ROM interfaces was often convenient to the consumer.
One advantage compared to competitors was that the card did not require terminate-and-stay-resident programs (TSRs) [1] , minimizing its conventional memory footprint. The card loaded its own operating system into the onboard RAM during system initialization via the card's 'SSINIT.EXE' utility program. The Soundscape also has a hardware MPU-401 implementation which, combined with the lack of TSRs, allowed a high degree of compatibility, which was a significant benefit as many DOS games often ran in a custom flavor of protected mode or were particularly demanding of conventional memory space.
Soundscape S-2000 has several descendants, including the SoundscapeDB, Soundscape Elite, Soundscape OPUS, Soundscape VIVO90, and AudioPCI. The original Soundscape S-2000 was replaced by the Soundscape II, a board based on the ELITE but without the daughtercard (it was an upgrade option).
The Soundscape was compatible with a variety of popular sound standards such as Ad Lib, Creative Sound Blaster 2.0, Microsoft Windows Sound System, General MIDI, Roland MT-32 (though with different instrument sounds) and MPU-401, in addition to its own, well-supported native Soundscape mode. Of critical importance at the time was support of the Creative Labs Sound Blaster, a card that was the ubiquitous sound standard of the day. Soundscape can emulate the Sound Blaster 2.0, an 8-bit monaural device with FM synthesis capability. While the digital sound emulation was quite good, the FM synthesis emulation leaves much to be desired. Emulating FM synthesis through software was too demanding for the CPUs of the time (typically an 80486), and so Ensoniq wrapped most of the FM synthesis commands to the card's sample-based synthesis engine, meaning that FM music did not sound correct because it was composed with FM synthesis in mind, not real instruments. This could be especially poor if the game was an older title that used FM synthesis for sound effects.
The reasoning behind using emulation instead of real hardware was cost and demand. FM synthesis hardware support for games at the time required an additional chip, the Yamaha OPL-2 or OPL-3. At the time Soundscape arrived, most games supported General MIDI output, offering high-quality music support for users who purchased the card and reducing the need for said OPL-3 synthesis chip. The board's SoundBlaster support could be toggled on and off, allowing use of a second sound card (usually an existing sound device) to take care of the actual OPL-3 FM synthesis if desired. The advantage of a single card that could do either, however, was very important for mind share amongst consumers, and was critical for OEM system sellers because adding a separate card would add cost to the system.
The SoundScape was well-supported by many mid-to-late 1990s programs, both directly and via General MIDI. Ensoniq released drivers for many operating systems, including IBM OS/2, MS-DOS, Microsoft Windows 3.1, Windows 95, and Windows NT. Ensoniq later released Microsoft DirectSound-capable drivers as well. In these operating systems, programs accessed the sound card through its driver, allowing full hardware support without the need for the software developer to support the card directly.

A sound card is an internal expansion card that provides input and output of audio signals to and from a computer under the control of computer programs. The term sound card is also applied to external audio interfaces used for professional audio applications.
Ad Lib, Inc. was a Canadian manufacturer of sound cards and other computer equipment founded by Martin Prevel, a former professor of music and vice-dean of the music department at the Université Laval. The company's best known product, the AdLib Music Synthesizer Card (ALMSC), or simply the AdLib as it was called, was the first add-on sound card for IBM compatibles to achieve widespread acceptance, becoming the first de facto standard for audio reproduction.
A music tracker is a type of music sequencer software for creating music. The music is represented as discrete musical notes positioned in several channels at chronological positions on a vertical timeline. A music tracker's user interface is traditionally number based. Notes, parameter changes, effects and other commands are entered with the keyboard into a grid of fixed time slots as codes consisting of letters, numbers and hexadecimal digits. Separate patterns have independent timelines; a complete song consists of a master list of repeated patterns.
Sound Blaster is a family of sound cards and audio peripherals designed by Singaporean technology company Creative Technology. The first Sound Blaster card was introduced in 1989, and since then, the Sound Blaster brand has become synonymous with high-quality computer audio.
Ensoniq Corp. was an American electronics manufacturer, best known throughout the mid-1980s and 1990s for its musical instruments, principally samplers and synthesizers.
The Gravis UltraSound or GUS is a sound card for the IBM PC compatible system platform, made by Canada-based Advanced Gravis Computer Technology Ltd. It was very popular in the demoscene during the 1990s.
The Roland MT-32 Multi-Timbre Sound Module is a MIDI synthesizer module first released in 1987 by Roland Corporation. It was originally marketed to amateur musicians as a budget external synthesizer with an original list price of $695. However, it became more famous along with its compatible modules as an early de facto standard in computer music. Since it was made prior to the release of the General MIDI standard, it uses its own proprietary format for MIDI file playback.
There have been various families of Yamaha audio controllers labelled as YMF7xx.
The Ensoniq ES-5506 "OTTO" is a chip used in implementations of sample-based synthesis. Musical instruments and IBM PC compatible sound cards were the most popular applications.
The SoundscapeDB is an Ensoniq-designed and produced MIDI daughtercard designed to interface with the "Waveblaster" pin header available on many older sound cards. It was released in 1994.
The Ensoniq Soundscape OPUS (SS-3016-NCD) is a Gateway 2000 OEM sound card, and possibly was used by other OEMs, but was never sold to Ensoniq's customers directly. It was a Soundscape-like board, using the Ensoniq "OPUS" multimedia sound chip that only was used on these OEM boards. It had a 1MB patch set ROM chip, resulting in a lesser MIDI quality compared to the Soundscape and Soundscape ELITE. The "OPUS" cards again carry the Motorola 68EC000 CPU. The variety of CD-ROM interfaces have been removed. Otherwise, however, the card is simply a cost-reduced Soundscape-compatible board with similar capabilities.
The Soundscape Elite was Ensoniq's high-end ISA PC sound card offering. It offers the highest MIDI quality of any PC sound card Ensoniq produced. The board is an evolution of the company's previous Soundscape S-2000. The Soundscape ELITE was launched in March 1995.
The Ensoniq AudioPCI is a PCI-based sound card released in 1997. It was Ensoniq's last sound card product before they were acquired by Creative Technology. The card represented a shift in Ensoniq's market positioning. Whereas the Soundscape line had been made up primarily of low-volume high-end products full of features, the AudioPCI was designed to be a very simple, low-cost product to appeal to system OEMs and thus hopefully sell in mass quantities.
