PROGRAM > SGX-2: String Resonance/Una Corda
5–1: String Resonance/Una Corda
5–1a: String Resonance
String Resonance
[Off, On]
When a note is played on an acoustic piano, any other un-
damped strings will resonate slightly, with an intensity
corresponding to their harmonic relationship to the played
note. An extreme example of this is heard when the damper
pedal is down, at which point all of the strings resonate
together. However, it also happens whenever a note is played
while one or more other harmonically related notes are held.
For instance, if you hold C2 and then sharply play and
release C3, you’ll hear a faint echo of the C3 ringing from
the C2 string.
On:
The SGX-2 models the individual string resonances
described above. (The sound when the damper pedal is down
is handled separately, by the
Damper Resonance
parameter.) The
Depth
parameter, below, controls the
intensity of the resonance. Polyphony may be slightly
reduced.
Off:
The string resonance modeling is disabled. This option
may offer slightly greater polyphony.
Depth
[000…127]
This controls the overall volume of the string resonance.
String Resonance Graphic
This graphic offers a visual overview of the sounding String
Resonance tones.
5–1b: Una Corda
Grand pianos typically have three pedals. From left to right,
these are the Una Corda pedal (also called the soft pedal), the
sostenuto pedal, and the sustain or damper pedal. When the
soft/Una Corda pedal is pressed, the piano action shifts
slightly to the right. This changes the positions of the
hammers relative to the strings, which alters the tone and
generally makes the sound softer. The amount of shift can be
adjusted by a piano technician to produce subtle or more
pronounced variations in timbre.
MIDI includes a standard Soft Pedal controller, CC#67. You
can assign this to the Foot Switch (see “Foot Switch Assign”
on page 655) or to SW1 or SW2 (see “1–8b: Panel Switch
Assign” on page 48).
Most NAUTILUS sounds, including some SGX-2
Piano
Types
, respond to CC#67 by scaling down note velocities—
as if you were playing a little softer than you actually are.
As an alternative to this approach, some SGX-2
Piano
Types
include dedicated Una Corda samples. When CC#67
is on, these
Piano Types
switch to a different, dedicated set
of samples instead of modifying velocity.
Una Corda
[Graphic]
If the selected
Piano Type
includes Una Corda samples, the
graphic in this section of the display will be displayed in
color. If it does not include Una Corda samples, the graphic
will be grayed out.
The graphic also shows whether the Una Corda pedal is
currently off (CC#67=0) or on (CC#67=127)—notice that
the left-most pedal moves up and down.
Finally, you can touch the graphic to toggle CC#67 on and
off. If you have SW1 or SW2 assigned to Soft (CC#67),
you’ll notice that its LED turns on and off as well.
