Korg Electribe ESX1-SD

   0 reviews  -  910 views

    The ideal tool for producing dance and many other types
    of music

    The ESX-1 provides nine drum parts and five
    synth parts. Since song arrangement editing is unified
    with the sound editing for each part, song production
    is quick and easy.

    “MMT (Multiple Modeling Technology)” tone generator

    The synth engine of the ES1X-1 features Korg’s latest
    technology — MMT (Multiple Modeling Technology).
    This system builds on the know-how that
    was developed for the DSP technology used in the
    Z1, MS2000, and Electribe series to create a wide
    range of timbral variations with a few simple operations.

    The oscillator section provides a total of sixteen
    different synthesis models that include not only
    standard analog synthesizer models such as Waveform,
    Sync, Cross Mod, and Ring Mod; but also new
    types not previously available, such as a Chord type
    that can produce a full chord from a single note, a
    Unison type that lets you detune the pitch of up to
    six oscillators to create an extremely thick sound,
    and a Waveshape type that mixes two oscillators
    and then modulates the result to generate complex

    The carefully selected parameters of the filter and
    modulation sections boast a greatly improved
    range, speed, and sound quality. In addition to four
    filter types that can dramatically vary the sound
    generated from the oscillator, the new Drive control
    can create the distinctive sound of analog distortion
    for sharp and powerful analog synth
    sounds. For totally far-out sounds, we’ve added
    BPF+ (Band Pass Filter Plus) with adjustable peaking,
    plus you can use other parameters in conjunction
    with modulation from the LFO or EG.

    207 drum waves for immediate use in your dance music

    The ESX-1 features 207 built-in drum waves that
    have been pre-processed to sound their best in your
    music, immediately.

    Analog synthesizer-style ease of editing

    The front panel provides knobs and switches for
    important sound parameters, allowing you to edit
    sounds in realtime while you perform, and letting
    you create sounds in the same way as on an analog

    Three simultaneous stereo effects processors

    The ESX-1 provides three stereo effect processors,
    each featuring 16 cutting-edge effect types. You can
    use the Chain function to modify the way in which
    the effects are connected to each other.

    192 internal patterns programmed for many genres of
    dance music

    The ESX-1 can hold 256 patterns in memory. Each
    one lets you store a sound and sequence (of up to
    128 steps) for each part. When shipped, 192 of the
    internal patterns are pre-programmed specifically
    for dance music and other modern music styles.
    64 songs A sequence of patterns, mute data, and knob movements can be saved as a “song” in each of the 64
    song memories.

    Intuitive pattern programming

    The sixteen step keys on the front panel allow you
    to enter data into pattern quickly, easily and intuitively.Of course, you can also use realtime recording or step recording.
    Motion sequencing

    The ESX-1’s Motion Sequence feature lets you
    record and loop knob movements and switch operations,
    letting you create time-varying changes
    in the tone during playback.

    Newly-developed VALVE FORCE vacuum tube circuit

    The ESX-1 features Korg’s newly-developed
    VALVE FORCE technology, a completely analog
    circuit that contains two actual vacuum tubes and
    can be used as a mastering effect to enhance the
    overall sound level. It delivers a rich, warm, and
    clearly-defined sound that cannot be replicated by
    digital technology alone. Use the TUBE GAIN knob
    to adjust the level of the ESX-1’s output signal
    being sent through the vacuum tubes, controlling
    the smooth distortion and rich overtone structure
    that vacuum tubes add to the sound. Even at lower
    volume levels, you can adjust the TUBE GAIN to
    enjoy great tube-quality sound in any situation.

    Process external audio sources

    You can connect an audio source to the audio in
    jack, and process that sound using the internal filter
    and on-board effects.

    Two-channel individual output jacks

    In addition to the L/MONO and R main stereo
    audio outputs, you can route any combination of
    parts to the two independent audio outputs.

    Auto BPM detection

    The ESX-1 can automatically detect the tempo of
    an audio source connected to the audio in jack, and
    apply that tempo to the current pattern. Of course,
    you can also use tap tempo to input the tempo, or
    synchronize to an external MIDI clock.

    SmartMedia™ slot

    Patterns and songs you create on the ESX-1 can be
    saved on SmartMedia™.
    Arpeggiator Use the ribbon controller and slider for intuitive and hands-on control of automatically generated arpeggios.


    The large back-lit LCD keeps you informed of the
    operating status and provides other information.

    Pattern writing on-the fly

    If you unexpectedly come up with a cool pattern
    or riff while playing patterns, you can write and
    save the pattern without stopping your performance.

    Saving your data on the ESX-1

    The patterns and songs you edit and create on the
    ESX-1 will be lost (the patterns and songs will return
    to their un-edited state) if you select a new
    pattern or song, or turn off the power before saving
    your changes. If you want to save a pattern or song that you created
    or edited, or changes you made to global data,
    you must perform the Write operation.
    You can always restore all songs and patterns to
    the factory settings if desired (☞p.89 “Restoring the
    factory settings”).

    About the vacuum tubes

    Do not attempt to remove, replace or change the
    tubes in the ESX-1. The tubes are not a user serviceable

    What is ?

    VALVE FORCE is KORG’s proprietary vacuum
    tube audio technology. The VALVE FORCE system
    provides the smooth distortion and rich
    overtone structure that is uniquely characteristic
    of analog tube circuitry. By providing the
    tube circuit with its own gain control, the
    VALVE FORCE system delivers excellent tonal
    quality in any situation.

    What is ? (Multi Modeling Technology)

    KORG’s new cutting-edge MMT (Multi Modeling
    Technology) engine is based on the vast
    knowledge acquired from years of DSP development
    — development that created the Prophecy,
    Z1, MS2000, OASYS PCI and Electribe series.
    This technology provides amazingly advanced
    sound possibilities while maintaining the
    simple operation that has been the hallmark of
    the Electribe series.
