Ensoniq ESQ-1 - 61-клавишный, чувствительный к скорости, восьми нотный полифонический и мультитембральный синтезатор, выпущенный Ensoniq в 1985 году. Он продавался как «синтезатор цифровых волн», но был ранней музыкальной рабочей станцией . Хотя генерация голоса обычно является субтрактивной, как и большинство аналоговых синтезаторов , предшествовавших ему, его генераторы не являются ни напряжением, ни « цифровым управлением », а настоящими цифровыми генераторами, обеспечиваемыми специальной микросхемой с волновой таблицей Ensoniq . Сигнальный тракт включает аналоговые резонансные фильтры нижних частот. и аналоговый усилитель.
Синтезатор также имеет полностью функциональный, хотя и грубый по современным стандартам, 8-трековый MIDI- секвенсор, который может воспроизводить либо свои внутренние звуки, либо внешнее MIDI-оборудование, либо и то, и другое, с емкостью 24000 нот (с возможностью расширения с помощью картриджей). Он обеспечивает квантование, пошаговое редактирование, примитивные формы редактирования копирования / вставки и может быть синхронизирован с внешним MIDI или встроенными часами.
ESQ-1 может хранить внутри 40 пресетов и имеет слот для картриджей для дополнительной возможности хранения. ESQ-M, версия синтезатора для монтажа в стойку, была выпущена примерно в 1987 году с теми же характеристиками, но без секвенсора.
Примечательно, что звуковой чип, лежащий в основе синтезатора, является детищем Роберта Яннеса , отца популярного чипа SID .
Озвучивание [ править ]
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 waveforms, including standard synthesis waveforms such as sawtooth and square, but also less usual ones such as "piano", "voice", or "bass" (note that, although multi-sampled, these are still single-cycle waveforms, not true samples as such).
Each oscillator can be independently volume-controlled via its dedicated digitally-controlled amplifier, and modulated. Oscillator amplifiers provide room to be overdriven, and thus produce moderate analog distortion as an additional effect on, for example, synth leads or organ sounds.
ESQ-1 has three independent LFOs, and three independent envelope generators 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 panning 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).
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, aftertouch, 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 SQ-80's keyboard.
Furthermore, Ensoniq ESQ-1 features amplitude modulation, oscillator sync, monophonic mode, and portamento.
Voice programming[edit]
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 filter sweep, 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.
Sequencing[edit]
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.
