Native Instruments B4 II - Manual (Page 63)

B4 II – 63
Keyclick amount adds an initial bite to the sound that is a popular part of the
tonewheel sound. The “bite” provided by higher keyclick volumes will add
definition to the organ tone (especially good for soloing), and is useful when
the B4 needs to cut through a dense mix.
The original B3 is not velocity sensitive. With the B4, however, you can add
variable velocity sensitivity by turning the
Velocity knob. This is a nice feature
to play accentuated riffs and can greatly enhance your organ voice.
The
Leakage parameter simulates a crosstalk between the tonewheel outputs.
As the value increases, the separation of the different tonewheels will decrease,
resulting in a wider frequency range of the produced tone. This simulates an
ageing effect. Tonewheels tend to get leaky and dolfed in badly maintained
B3 organs over the years. Use it to your advantage when the sound has to
be a bit trashy.
The
Sustain knob in the Pedal Bass section provides control over the volume
envelope of the bass pedal sounds. If turned completely to the left, the bass
pedal notes sound only as long as the incoming MIDI note signals dictate. The
further the knob is turned to the right, the longer the notes will sound even
after the key/pedal has been released. If you are using a MIDI pedal controller
you can use this as a playing aid for held notes.
The
String/Organ switch changes the decay characteristics of the bass sustain
function. In String mode it acts like a plucked bass string, sloping the volume
to zero after a key is pressed. In Organ mode the volume is held at full volume
for the complete hold phase.
Tube Amp Settings and Indicators
The Tube Amp Overdrive Indicator Tube provides feedback as to the amount
of overdrive produced by the tube amp model. As overdrive is increased, the
depicted tube will glow brighter.
Tube Amp Drive determines the preamp level sent to the main tube amp model.
At high levels, this will force the tube amp into overdrive, and can add a beefy
Rock sound to the organ.
