Ensoniq OTTO Synthesizer

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.

Contents

OTTO is capable of altering the pitch and timbre of a digital recording and is capable of operating with up to 32 channels at once. Each channel can have several parameters altered, such as pitch, volume, waveform, and filtering. The chip is a VLSI device designed to be manufactured on a 1.5 micrometre double-metal CMOS process. It consists of approximately 80,000 transistors. It was part of the fourth generation of Ensoniq audio technology.

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.

A sampler is an electronic musical instrument that records and plays back samples. Samples may comprise elements such as rhythm, melody, speech, sound effects or longer portions of music.

The Ensoniq Mirage is one of the earliest affordable sampler-synths, introduced in 1984 as Ensoniq's first product. Introduced at a list price of $1,695 with features previously only found on more expensive samplers like the Fairlight CMI, the Mirage sold nearly 8,000 units in its first year - more than the combined unit sales of all other samplers at that time.

Ensoniq Corp. was an American electronics manufacturer, best known throughout the mid-1980s and 1990s for its musical instruments, principally samplers and synthesizers.

A rompler is an electronic musical instrument that plays pre-fabricated sounds based on audio samples. The term rompler is a blend of the terms ROM and sampler. In contrast to samplers, romplers do not record audio. Both may have additional sound editing features, such as layering several waveforms and modulation with ADSR envelopes, filters and LFOs.

Ensoniq ESQ-1 is a 61-key, velocity sensitive, eight-note polyphonic and multitimbral synthesizer released by Ensoniq in 1985. It was marketed as a "digital wave synthesizer" but was an early Music Workstation. Although its voice generation is typically subtractive in much the same fashion as most analog synthesizers that preceded it, its oscillators are neither voltage nor "digitally controlled", but true digital oscillators, provided by a custom Ensoniq wavetable chip. The signal path includes analog resonant low-pass filters and an analog amplifier.

The Ensoniq Performance Sampler (EPS) was one of the first few affordable samplers on the market. It was manufactured from 1988 to 1991 by Ensoniq in Malvern, Pennsylvania, US. The EPS is a 13-bit sampler and replaced the Mirage - widely regarded as the first truly affordable sampling keyboard.

<span class="mw-page-title-main">Ensoniq Signal Processor</span> Musical instrument microchip

The Ensoniq ESP was used in many of the company's musical instruments and on their Soundscape Elite PC ISA sound card. It was used to enhance the synthesizer's audio samples with digital effects, enhancing the realism of the overall sound.

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.

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.

<span class="mw-page-title-main">Ensoniq AudioPCI</span> PCI-based sound card

The Ensoniq AudioPCI is a Peripheral Component Interconnect (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.

<span class="mw-page-title-main">Sound Blaster Live!</span>

Sound Blaster Live! is a PCI add-on sound card from Creative Technology Limited for PCs. Moving from ISA to PCI allowed the card to dispense with onboard memory, storing digital samples in the computer's main memory and then accessing them in real time over the bus. This allowed for a much wider selection of, and longer playing, samples. It also included higher quality sound output at all levels, quadrophonic output, and a new MIDI synthesizer with 64 sampled voices. The Live! was introduced in August 1998 and variations on the design remained Creative's primary sound card line into the early 2000's.

The Korg DSS-1 is a 12-bit polyphonic sampling synthesizer released in September 1986. It came out at a time when many of the popular synthesizer companies were beginning to get into sampling, an area of sound design that had previously been left to a handful of fledgling companies such as Fairlight, E-mu, and Ensoniq. Like Yamaha and Casio, however, Korg did not stay long in the sampling arena. The DSS-1 was the company's only sampler until 1998 when Korg introduced sampling options on their Triton and Trinity series of workstations, and on their Electribe series of drum-and-phrase samplers.

<span class="mw-page-title-main">Ensoniq ASR-10</span> Digital musical instrument

The Ensoniq ASR-10 was a sampling keyboard produced by Ensoniq between 1992 and 1998. The ASR-10 was a follow-up product to the very popular Ensoniq EPS and Ensoniq EPS-16+ performance samplers, and was also available with a piano style weighted keyboard (ASR-88) and a rackmount version (ASR-10R). At the time, the machine was one of the most powerful samplers available.
