   0 reviews  -  2401 views

    The U-20 contains
    high-quality digital sounds, and can be
    used as a multi-timbral sound generator.
    It also functions as a MIDI keyboard
    controller, for a wide range of applications
    both on stage and in the studio.

    The U-20 has features such as

    •High-quality RS-PCM Sound Generation
    The U-20 contains 128 types of highquality
    sound, ranging from piano to
    instruments appropriate for a classical
    or jazz ensemble, and synth sounds for
    rock or fusion. Parameters (elements of
    sound) for pitch and level can be used
    for detailed control over the nuances of
    each tone (sound).

    In addition to the built-in tones, tones
    from PCM cards (sound Hbrary SN-UllO
    series) sold for the U-llO can also be


    The U-20 contains a multi-timbral sound
    generator that can handle 6 parts and
    an additional rhythm part. The sounds
    (timbres) and effects of each part can
    be stored in 64 different settings as
    sound patches. When using a MIDI
    sequencer, a single U-20 can fill the role
    of an entire ensemble.

    For the rhythm part, tone assignments
    and settings can be stored as one of
    four rhythm sets.

    •Flexible Control Functions
    Settings determining how controllers
    affect performance can be stored as one
    of 64 keyboard patches, allowing you to
    modify sounds as you play, or control
    different types of external tone

    •Built-in Digital Effect
    A digital reverb/chorus effect is built
    in, providing a spacious feeUng of
    stereo depth. Each sound patch has its own effect settings.
    •Chord Play Function

    A chord can be assigned to each key,
    allowing you to play chords with a
    single finger. Since a different chord
    can be assigned to each key C, C# — B,
    you can perform using diatonic chords
    or harmonies in thirds. Eight sets of
    chords can be stored in the U-20 (one
    set includes C, C#—B). While playing,
    you can instantly switch between any
    two previously specified sets of chords.
    ^Arpeggio Play Function
    A chord you hold down can be
    automatically arpeggiated. An arpeggiation
    pattern can be set for each keyboard
    patch, allowing you to use the musically
    appropriate pattern for each situation.
    Arpeggio can be switched on/off using
    a button, and can be used in conjunction
    with the chord play function.

    Jump Function

    The jump function allows you to
    instantly jump to a specified screen. In
    addition to the pre-defined screens, you
    may also define your own. Using the
    jump fimction can .-make the editing
    process more efficient.

    IRAM Card for Convenient Data Storage
    A separately sold RAM card (M-256E)
    can store the entire settings of the
    U-20. Patches stored in a RAM card can
    instantly be recalled for use.

    Multi-timbral Sound Generator Section
    The multi-timbral sound generator can store 64 Sound
    Patches. Each Sound Patch consists of Parts 1 —6 and
    a Rhythm part.

    Each part corresponds to a musician. For example, part
    1 might be a pianist, part 2 might be a bassist, etc. It
    goes without saying that the rhythm part is the drummer.
    The instrument (timbre) used by each musician can be
    freely selected, and changed even while playing. The
    rhythm part can select from four types of drum /
    percussion sets (rhythm sets). In addition, each Sound
    Patch can specify the volume of each instrument (level),
    the position of each instrument (pan), and the ambiance
    of the performing environment (effect). Also, the solids
    of two or more Parts can be combined to make even
    richer, more complex sounds. In this way, you can create
    Soimd Patches with various combinations of instruments,
    and instantly change to an entirely different instrumental
    ensemble simply by selecting a Sound Patch.

    Keyboard Controller Section

    The controller section sends playing instructions to the
    musicians. When you play the keyboard, the instrument
    of the specified part will sound. Use the bender lever
    to add vibrato or pitch change. Controller section settings
    can be stored as one of 64 keyboard patches.
    When using a MIDI sequencer etc., you can use the
    keyboard to play along with the sequence.
    The U-20 can also be used as a keyboard controller to
    control external sound generator modules.
