SOUND
RHODY
Electric piano Sounds that simulates the famous Fender Rhodes
HAMMER
Range: -50...0...+50
NRPN MSB=0, NRPN LSB=0
Data Entry MSB Range: 14...64...114
Modifies the characteristic and size of the hammer that, during the impact with the tine, determines the sound
loudness and timbre.
When a key is pressed on the piano keyboard, the corresponding hammer strikes the thin cylindrical bar called "tine"
and then rebounds, allowing the tine to vibrate at its resonant frequency. The greater the key velocity, the greater is the
energy transferred from the hammer to the tine, and the louder the note produced. The hammer contact time with the
tine is very short, but during this time the hammer greatly influences the timbre and loudness, not only at the attack but
for all the sound evolution.
DAMPER FELT
Range: -50...0...+50
NRPN MSB=0, NRPN LSB=1
Data Entry MSB Range: 14...64...114
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.
The effect of the DAMPER FELT parameter is more audible on bass notes.
TONE BAR SIZE
Range: -50...0...+50
NRPN MSB=0, NRPN LSB=2
Data Entry MSB Range: 14...64...114
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.
The effect of the TONE BAR SIZE parameter is more audible on bass notes.
TONE BAR BODY
Range: -50...0...+50
NRPN MSB=0, NRPN LSB=3
Data Entry MSB Range: 14...64...114
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 result in a nice bell-like attack that
decays much more rapidly than the 'sustain' portion of the sound. By changing the TONE BAR BODY you can modify
the resonance of the tone generator assembly with the consequence to changing the bell-like characteristic of the
sound.
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
Range: -50...0...+50
NRPN MSB=0, NRPN LSB=4
Data Entry MSB Range: 14...64...114
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.
The effect of the TINE POSITION parameter can be better heard on bass notes.
