  • Sequential Prophet-5

    Programmable polyphonic analog synthesizer

    Synthesizer · United States

    The Sequential Prophet-5, released in 1978, was the first fully programmable polyphonic analog synthesizer, letting players store and recall patches. Its five voices, dual oscillators, and warm sound made it a landmark instrument used across pop, film, and electronic music.

  • Sequential Prophet Rev2

    Eight- or sixteen-voice analog polyphonic synthesizer

    Synthesizer · United States

    The Sequential Prophet Rev2, introduced in 2017 as a successor to the Prophet '08, is an analog polyphonic synthesizer available in eight- or sixteen-voice configurations. Each voice uses two digitally controlled analog oscillators (DCOs) and a Curtis analog low-pass filter with switchable two- and four-pole operation, with two layers per program for stacked or split bi-timbral sounds. It is offered as a five-octave Fatar keyboard and a desktop module.

  • Sequential Prophet-6

    Six-voice analog polyphonic synthesizer

    Synthesizer · United States

    The Sequential Prophet-6, introduced in 2015, is a six-voice analog polyphonic synthesizer designed by Dave Smith as a modern descendant of the original Prophet-5. Each voice has two discrete voltage-controlled oscillators plus a sub-oscillator, a four-pole resonant low-pass filter inspired by the Prophet-5 and a two-pole high-pass filter, with a dual analog/digital effects section, polyphonic step sequencer, and arpeggiator.

  • Sequential Prophet-10

    Ten-voice analog polyphonic synthesizer

    Synthesizer · United States

    The Sequential Prophet-10 is a ten-voice, bi-timbral analog polyphonic synthesizer reissued in 2020 alongside the Prophet-5 Rev4. It shares the Prophet-5 signal path with two CEM 3340 voltage-controlled oscillators per voice and a switchable four-pole resonant low-pass filter, doubling the voice count to allow layered or split bi-timbral performance. It ships in a five-octave keyboard version and a desktop module.

  • Oberheim OB-X8

    Eight-voice analog polyphonic synthesizer

    Synthesizer · United States

    The Oberheim OB-X8, introduced in 2022, is an eight-voice pure-analog polyphonic synthesizer that recreates and combines the three classic Oberheim voice architectures of the OB-X, OB-Xa, and OB-8 in a single instrument. Each voice has two discrete SEM-lineage VCOs, with both the original SEM discrete filter and Curtis CEM3320 two- and four-pole filters. It ships as a 61-key Fatar keyboard and as a desktop module.

  • Sequential Take 5

    Five-voice compact analog polyphonic synthesizer

    Synthesizer · United States

    The Sequential Take 5, introduced in 2021, is a compact five-voice analog polyphonic synthesizer with two voltage-controlled oscillators and a sub-oscillator per voice and a four-pole resonant analog low-pass filter derived from the Prophet-5 Rev4. Built around a 44-key Fatar keybed, it includes variable-shape oscillators, dual digital effects with overdrive, a 64-step polyphonic sequencer, and an arpeggiator.

  • Sequential Trigon-6

    Six-voice analog polyphonic synthesizer

    Synthesizer · United States

    The Sequential Trigon-6, introduced in 2022, is a six-voice analog polyphonic synthesizer built around three discrete voltage-controlled oscillators per voice offering simultaneously selectable triangle, sawtooth, reverse-sawtooth, and variable-width pulse waves. It uses a switchable two/four-pole discrete resonant ladder low-pass filter, and is available as a 49-key keyboard or a desktop module, with a 64-step polyphonic sequencer and arpeggiator.

  • Sequential Pro 3

    Hybrid mono/paraphonic synthesizer

    Synthesizer · United States

    The Sequential Pro 3, introduced in 2020, is a hybrid monophonic and three-note paraphonic synthesizer combining two analog voltage-controlled oscillators with a DSP-based digital wavetable oscillator. It features three switchable filters - a four-pole Prophet-6 low-pass, a four-pole transistor ladder, and a two-pole OB-6 state-variable filter - plus a deep 16-track sequencer. A Pro 3 SE version adds a tilt-up panel and walnut trim.

  • Make Noise 0-Coast

    Single-voice patchable semi-modular synthesizer

    Synthesizer · United States

    The Make Noise 0-Coast is a single-voice patchable semi-modular desktop synthesizer that blends East Coast and West Coast techniques in what Make Noise calls 'no-coast synthesis.' It centers on a triangle-core analog VCO with analog FM, an overtone/multiply section, slope generator, and dynamics gate, and works as a standalone monosynth or a patchable instrument with Eurorack-compatible signals.
