SOUND MALLET
Xylophone, vibraphone and marimba Sounds
BAR MATERIAL
Range: -50...0...+50
NRPN MSB=0, NRPN LSB=0
Data Entry MSB Range: 14...64...114
Allows you to change the character of the sound and release time.
The bar dimensions are related with the frequency of the produced note, while the tone character and length depends
on the bar material. The more rigid and homogeneous (metal) the bar material, the sharper the resonances and the
slower is the sound decay.
The more elastic and anisotropic (wood), the bar material, the weaker the resonances and the faster the sound decay.
Positives values of the BAR MATERIAL parameter correspond with a more rigid material, while negative values
correspond to a more elastic material.
MALLET MATERIAL
Range: -50...0...+50
NRPN MSB=0, NRPN LSB=1
Data Entry MSB Range: 14...64...114
Determines the sound loudness and brigthness.
When the mallet hits the bar it transfers energy that allows the bar to vibrate. The mallet material influences the nature
of the impact and consequently the tone of the produced sound. The more the mallet material is rigid and
homogeneous, the faster the sound attack and more "thin" the initial sound.
The softer the material, the fuller low tones of the initial sound.
Positives values of the MALLET MATERIAL parameter correspond to a more rigid material, while negative values
correspond to a softer material.
HIT POSITION
Range: -50...0...+50
NRPN MSB=0, NRPN LSB=2
Data Entry MSB Range: 14...64...114
allows you to change the point where the mallet hits the bar changing the timbre of the sound .
Each time the mallet hits the bar, the bar starts to oscillate at its resonant frequency with a timbre that depends on the
hit position. The hit position influences the relative amplitudes of the various overtones of the sound.
HIT RANGE
Range: -50...0...+50
NRPN MSB=0, NRPN LSB=3
Data Entry MSB Range: 14...64...114
Allows you to change the width of the area where the mallet hits the bar.
When a musician plays a mallet instrument, he/she intentionally hits the bar in a specific point in order to get the
desired timbre (see HIT POSITION Parameter). However, because of human imprecision the effective hit point can
randomly change around the desired hit point. The MALLET HIT RANGE parameter allows you to set the size of the
area within the effective hit point can randomly take place. This unique feature allows you to get a more realistic
performance even by using the piano keyboard.
The effect can be easily heard when the the mallet hit range is large (positive values) and the same note is repeatedly
played. The greater the range, the greater the variance of the notes timbre.
ROTOR ANGLE
Range: -50...0...+50
NRPN MSB=0, NRPN LSB=4
Data Entry MSB Range: 14...64...114
Beneath each bar there is a tube with a butterfly valve, moved by an electric rotor. When the rotor is off (see Rotor
On/Off parameter), the parameter allows to rotate the valve and modify the sound character.
ROTOR SPEED
Range: -50...0...+50
NRPN MSB=0, NRPN LSB=5
Data Entry MSB Range: 14...64...114
This parameter controls the rotation speed of the butterfly valve (when the rotor is on). The rotation generates a tremolo
effect.
ROTOR ON/OFF
Range: -50...0...+50
NRPN MSB=0, NRPN LSB=6
Data Entry MSB Range: 14...64...114
Set the rotor on or off. The rotor rotates the butterfly valve.
