   (0 reviews)

The U-20 contains

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.
