title="Multitimbral">multitimbral</a> <a href="/wiki/Synthesizer" title="Synthesizer">synthesizer</a> released by <a href="/wiki/Ensoniq" title="Ensoniq">Ensoniq</a> in 1985. It was marketed as a "digital wave synthesizer" but was an early <a href="/wiki/Music_Workstation" class="mw-redirect" title="Music Workstation">Music Workstation</a>. Although its voice generation is typically <a href="/wiki/Subtractive_synthesis" title="Subtractive synthesis">subtractive</a> in much the same fashion as most <a href="/wiki/Analog_synthesizers" class="mw-redirect" title="Analog synthesizers">analog synthesizers</a> that preceded it, its <a href="/wiki/Electronic_oscillators" class="mw-redirect" title="Electronic oscillators">oscillators</a> are neither <a href="/wiki/Voltage_controlled_oscillator" class="mw-redirect" title="Voltage controlled oscillator">voltage</a> nor "<a href="/wiki/Digitally_controlled_oscillator" title="Digitally controlled oscillator">digitally controlled</a>", but true digital oscillators, provided by a custom Ensoniq <a href="/wiki/Table-lookup_synthesis" class="mw-redirect" title="Table-lookup synthesis">wavetable</a> chip. The signal path includes analog resonant low-pass <a href="/wiki/Low_pass_filter" class="mw-redirect" title="Low pass filter">filters</a> and an analog amplifier. </p><p>The synth also features a fully functional, 8-track <a href="/wiki/MIDI" title="MIDI">MIDI</a> <a href="/wiki/Music_sequencer" title="Music sequencer">sequencer</a> that can run either its internal sounds, external MIDI equipment, or both, with a capacity of 2, 400 notes (expandable via cartridges). It provides quantization, step-editing, primitive forms of copy/paste editing, and can be synchronized with external MIDI or tape-in clock. </p><p>The ESQ-1 had a particularly easy user interface, especially for a feature-filled digital synthesizer of the time and a multitimbral workstation/sequencer , by way of a then-large 40-character x 2-line display, ten softkeys (5 above and 5 below display), and system of all dedicated direct-access buttons per ten-parameter/patch page, meaning there was no "menu diving" within hierarchical series of sub-pages whatsoever. </p><p>ESQ-1 can store 40 rewritable sound patches internally, and features a rewritable EEPROM or fixed ROM cartridge slot for access to 80 additional patches. ESQ-M, a rackmount version of the synthesizer, was released circa 1987, with the same specifications but without the sequencer and a significantly smaller display and less user-friendly interface. </p><p>Notably, the <a href="/wiki/Table-lookup_synthesis" class="mw-redirect" title="Table-lookup synthesis">sound</a> chip at the core of the synth, the 5503 Digital Oscillator Chip (DOC), is a brainchild of <a href="/wiki/Robert_Yannes" class="mw-redirect" title="Robert Yannes">Robert Yannes</a>, father of the popular Commodore <a href="/wiki/MOS_Technology_SID" class="mw-redirect" title="MOS Technology SID">SID chip</a>.The chip was previously used in Ensoniq's Mirage sampler, later in ESQ-1's enhanced successor SQ-80, as well as the Apple IIGS personal computer. </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="Voicing">Voicing</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Ensoniq_ESQ-1&amp;action=edit&amp;section=1" title="Edit section: Voicing"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>The ESQ-1 features eight voices with three oscillators per voice, and is fully multi-timbral. Despite eight voice polyphony, it is capable of tracking nine voices - when using eight internal sounds in the sequencer, one additional internal or cartridge sound can be controlled independently. The wave ROM contains 32 different <a href="/wiki/Waveform" title="Waveform">waveforms</a>, including standard synthesis waveforms such as <a href="/wiki/Sawtooth_wave" title="Sawtooth wave">sawtooth</a> and <a href="/wiki/Square_wave" title="Square wave">square</a>, but also less usual ones such as "piano", "voice", or "bass" (note that, although multi-sampled, these are still single-cycle waveforms, not <a href="/wiki/Sample-based_synthesis" title="Sample-based synthesis">true samples</a> as such). </p><p>Each oscillator can be independently volume-controlled via its dedicated <i>digitally-controlled</i> <a href="/wiki/Amplifier" title="Amplifier">amplifier</a>, and modulated. Oscillator amplifiers provide room to be <i>overdriven</i>, and thus produce moderate analog distortion as an additional effect on, for example, synth leads or organ sounds. </p><p>ESQ-1 has three independent <a href="/wiki/Low-frequency_oscillation" title="Low-frequency oscillation">LFOs</a>, and three independent <a href="/wiki/ADSR_envelope" class="mw-redirect" title="ADSR envelope">envelope generators</a> which can be programmed to modulate any number of parameters. The fourth envelope generator is hardwired to the main output amplifier though it can still be used as a modulation source for other parameters as well. The output amplifier (DCA4) also provides programmable <a href="/wiki/Panning_(audio)" title="Panning (audio)">panning</a> for each voice. Its envelope generators allow numerical level/rate settings, and like many other synthesis parameters, allow the use of negative values. Furthermore, they can be set to track for keyboard velocity and alter the attack segment of the envelope (enabling a voice to have a soft attack when played softly or vice versa), and note position to alter envelope length (for instance, on a piano sound, having shorter notes higher up the keyboard). </p><p>Its low-pass filters are analog (CEM 3379), but digitally controlled, and thus can be modulated with a significant number of sources, including LFO, envelopes, velocity, <a href="/wiki/Aftertouch" class="mw-redirect" title="Aftertouch">aftertouch</a>, modulation wheel, etc. Even though the filter resonance can be driven to extreme effect, the resonance setting features only 32 steps, and the filters do not fully self-oscillate. The ESQ-1's keybed doesn't feature aftertouch, but the synthesis engine is capable of processing polyphonic aftertouch over MIDI, such as the polyphonic aftertouch implementation of the <a href="/wiki/Ensoniq_SQ-80" title="Ensoniq SQ-80">SQ-80</a>'s keyboard. </p><p>Furthermore, Ensoniq ESQ-1 features <a href="/wiki/Amplitude_modulation" title="Amplitude modulation">amplitude modulation</a>, <a href="/wiki/Oscillator_sync" title="Oscillator sync">oscillator sync</a>, monophonic mode, and <a href="/wiki/Portamento" title="Portamento">portamento</a>. </p> <div class="mw-heading mw-heading2"><h2 id="Voice_programming">Voice programming</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Ensoniq_ESQ-1&amp;action=edit&amp;section=2" title="Edit section: Voice programming"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Each section of the synthesizer is called to screen via a dedicated button, and settings inside each category are made by using one data slider or two +/- buttons. Settings do not influence the sound directly, but rather, changes are heard only when the next note is played. In other words, one can't use the data slider to change the filter cutoff setting as a way of producing a <i>filter sweep</i>, but can use any of the modulation sources to the same effect (including envelopes, the modulation wheel, modulation pedal, or external controllers over MIDI). Any modulation source can be set up to modulate any page of any given program (such as OSC1, DCA1, Filter, etc.). Voices are organized in four banks, and all presets can be overwritten by the user, and exported as banks via the tape-out port in the form of audio-encoded data, thus making it easy to store any number of user-created banks on tape or, for example, a computer. Additionally, it has a cartridge slot for voice cartridges. Commercial cartridges come with two sets of four banks of voices each, but there are also blank or rewritable cartridges. </p> <div class="mw-heading mw-heading2"><h2 id="Sequencing">Sequencing</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Ensoniq_ESQ-1&amp;action=edit&amp;section=3" title="Edit section: Sequencing"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>ESQ-1 has an eight track sequencer, which can be set to use any of the internal or cartridge sounds, or alternatively set to MIDI output channel for any track separately, while still being able to control a local voice on that track as well. Mixer section provides volume control for local sounds. MIDI output sends program changes, and the sequencer records continuous controller data such as pitch and modulation wheel use. The sequencer capacity can be expanded with additional cartridges. Events can be recorded in real-time (playing the keyboard or using any of the controllers with the optional use of integrated metronome with pre-count), or step by step. Recorded data can be quantized and tracks can be merged and copied. Changes and edits can be auditioned non-destructively. The sequencer can be set to slave or master clock, via MIDI or tape, and optionally controlled for play, record and punch-in via a footswitch. Sequences of up to 999 bars can be chained to "songs", with programmable number of repetitions for each, or sequenced live, since a currently selected sequence will play only after the previous one ends. Each "sequence" can use a different tempo. </p> <div class="mw-heading mw-heading2"><h2 id="See_also">See also</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Ensoniq_ESQ-1&amp;action=edit&amp;section=4" title="Edit section: See also"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <ul><li><a href="/wiki/Ensoniq_SQ-80" title="Ensoniq SQ-80">Ensoniq SQ-80</a></li></ul> <div class="mw-heading mw-heading2"><h2 id="References">References</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Ensoniq_ESQ-1&amp;action=edit&amp;section=5" title="Edit section: References"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <style data-mw-deduplicate="TemplateStyles:r1239543626">.mw-parser-output .reflist{margin-bottom:0.5em;list-style-type:decimal}@media screen{.mw-parser-output .reflist{font-size:90%}}.mw-parser-output .reflist .references{font-size:100%;margin-bottom:0;list-style-type:inherit}.mw-parser-output .reflist-columns-2{column-width:30em}.mw-parser-output .reflist-columns-3{column-width:25em}.mw-parser-output .reflist-columns{margin-top:0.3em}.mw-parser-output .reflist-columns ol{margin-top:0}.mw-parser-output .reflist-columns li{page-break-inside:avoid;break-inside:avoid-column}.mw-parser-output .reflist-upper-alpha{list-style-type:upper-alpha}.mw-parser-output .reflist-upper-roman{list-style-type:upper-roman}.mw-parser-output .reflist-lower-alpha{list-style-type:lower-alpha}.mw-parser-output .reflist-lower-greek{list-style-type:lower-greek}.mw-parser-output .reflist-lower-roman{list-style-type:lower-roman}</style><div class="reflist"> <div class="mw-references-wrap"><ol class="references"> <li id="cite_note-1"><span class="mw-cite-backlink"><b><a href="#cite_ref-1">^</a></b></span> <span class="reference-text"><style data-mw-deduplicate="TemplateStyles:r1238218222">.mw-parser-output cite.citation{font-style:inherit;word-wrap:break-word}.mw-parser-output .citation q{quotes:"\"""\"""'""'"}.mw-parser-output .citation:target{background-color:rgba(0,127,255,0.133)}.mw-parser-output .id-lock-free.id-lock-free a{background:url("//upload.wikimedia.org/wikipedia/commons/6/65/Lock-green.svg")right 0.1em center/9px no-repeat}.mw-parser-output .id-lock-limited.id-lock-limited a,.mw-parser-output .id-lock-registration.id-lock-registration a{background:url("//upload.wikimedia.org/wikipedia/commons/d/d6/Lock-gray-alt-2.svg")right 0.1em center/9px no-repeat}.mw-parser-output .id-lock-subscription.id-lock-subscription a{background:url("//upload.wikimedia.org/wikipedia/commons/a/aa/Lock-red-alt-2.svg")right 0.1em center/9px no-repeat}.mw-parser-output .cs1-ws-icon a{background:url("//upload.wikimedia.org/wikipedia/commons/4/4c/Wikisource-logo.svg")right 0.1em center/12px no-repeat}body:not(.skin-timeless):not(.skin-minerva) .mw-parser-output .id-lock-free a,body:not(.skin-timeless):not(.skin-minerva) .mw-parser-output .id-lock-limited a,body:not(.skin-timeless):not(.skin-minerva) .mw-parser-output .id-lock-registration a,body:not(.skin-timeless):not(.skin-minerva) .mw-parser-output .id-lock-subscription a,body:not(.skin-timeless):not(.skin-minerva) .mw-parser-output .cs1-ws-icon a{background-size:contain;padding:0 1em 0 0}.mw-parser-output .cs1-code{color:inherit;background:inherit;border:none;padding:inherit}.mw-parser-output .cs1-hidden-error{display:none;color:var(--color-error,#d33)}.mw-parser-output .cs1-visible-error{color:var(--color-error,#d33)}.mw-parser-output .cs1-maint{display:none;color:#085;margin-left:0.3em}.mw-parser-output .cs1-kern-left{padding-left:0.2em}.mw-parser-output .cs1-kern-right{padding-right:0.2em}.mw-parser-output .citation .mw-selflink{font-weight:inherit}@media screen{.mw-parser-output .cs1-format{font-size:95%}html.skin-theme-clientpref-night .mw-parser-output .cs1-maint{color:#18911f}}@media screen and (prefers-color-scheme:dark){html.skin-theme-clientpref-os .mw-parser-output .cs1-maint{color:#18911f}}</style><cite class="citation web cs1"><a rel="nofollow" class="external text" href="http://www.vintagesynth.com/ensoniq/ens_esq1.php">"Vintage Synth Explorer"</a>.</cite><span title="ctx_ver=Z39.88-2004&amp;rft_val_fmt=info%3Aofi%2Ffmt%3Akev%3Amtx%3Abook&amp;rft.genre=unknown&amp;rft.btitle=Vintage+Synth+Explorer&amp;rft_id=http%3A%2F%2Fwww.vintagesynth.com%2Fensoniq%2Fens_esq1.php&amp;rfr_id=info%3Asid%2Fen.wikipedia.org%3AEnsoniq+ESQ-1" class="Z3988"></span></span> </li> </ol></div></div> <ul><li><link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1238218222"><cite class="citation book cs1"><a rel="nofollow" class="external text" href="http://www.buchty.net/~buchty/esq1/files/ESQ1-MANUAL_TOTAL.pdf"><i>Ensoniq ESQ'1 Digital Wave Synthesizer and Sequencer Musicians Manual Version 2.0</i></a> <span class="cs1-format">(PDF)</span>.
