Reference Manual – Sound Edit Parameters
DAMPER FELT
How to access: press [SOUND EDIT], select the SOUND ENGINE block,
select the Damper Felt field.
Damper Felt
Description: The parameter allows you to change the sound
release time.
When a key is released the corresponding damper felt enters in contact with
the vibrating tine and this damps the sound vibration. The larger the damper
felt the greater the absorbed energy and the shorter the sound release time.
HINTS AND TIPS: The effect of the parameter is more audible on
Damper Felt
bass notes.
TONE BAR SIZE
How to access: press [SOUND EDIT], select the SOUND ENGINE block,
select the Tone Bar Size field.
Description: The Tone Bar Size parameter allows you to change the decay
time of the sound.
When a key is pressed, a hammer hits the thin cylindrical bar called a 'Tine',
which then vibrates like a reed. The Tine is connected to another resonator
with reed-like structure called Tone Bar which is free to resonate at a
frequency very near that of the tine. Vibrations can pass from the Tine bar to
the Tone Bar that serves only to store vibrational energy. The larger the Tone
Bar, the greater the stored energy and the longer the sound decay time.
HINTS AND TIPS: The effect of the parameter is more audible on bass notes..
Tone Bar Size
TONE BAR BODY
How to access: press [SOUND EDIT], select the SOUND ENGINE block,
select the Tone Bar Body field.
Description: The Tone Bar Body parameter allows you to change the initial
bell-like characteristic of the sound.
When a key is pressed, a hammer hits the thin cylindrical bar called a 'Tine',
which then vibrates like a reed. The Tine transfers parts of his energy to the
Tone Bar allowing the whole tone generator assembly to vibrate
simultaneously in many modes, or patterns. The high frequency modes die
out more rapidly than the low frequency. The tone generator assembly is
shaped and mounted in such a way that these higher-frequency modes
Tone
result in a nice bell-like attack that decays much more rapidly than the 'sustain' portion of the sound. By changing the
Bar Body
you can modify the resonance of the tone generator assembly with the consequence to changing the bell-like
characteristic of the sound.
HINTS AND TIPS: When the Tone Bar Body parameter has a value of -50 the sound is dull, while with the value is +50 the
sound is brilliant with pronounced bell-like characteristic.
TINE POSITION
How to access: press [SOUND EDIT], select the SOUND ENGINE block,
select the Tine Position field.
Tine Position
Description: The parameter allows you to change the sound
harmonic content.
When a key is pressed, a hammer hits a thin cylindrical bar called a 'tine',
which then vibrates like a reed. Such vibration is captured by the pickup in
front of the tine. When the tine motion doesn't exceed the range of the
pickup, the output waveform is a good replica of the tone bar's motion. On
the other hand, with loud tones, when the tine swings outside the pickup
range, the output waveform is 'distorted' with a consequent increase of the
harmonic content. Thus the beginning of the notes has more harmonic content than the end, and loud notes have more
overtones than soft ones. The Tine Position allows you to move the tine position with respect to the pickup position
determining a change in the harmonic content.
HINTS AND TIPS: The effect of the Tine Position parameter can be better heard on bass notes.
