FXAlg #735/6: KB3 FX
Algorithm Reference-114
highest frequency. The crossover filters for the lower and upper drivers may be set independently. A small amount
of overlap seems to work well. The gains of the high and low band signals may also be separately controlled.
At this point KB3 FXBus has finished its processing and passes the high and low signals to the KB3 AuxFX algorithm
which contains the rotating-speaker routine. See the section in this book on FXAlg #733 for details.
Parameters (KB3 FXBus):
PAGE 1
PAGE 2
In/Out
When set to ÒInÓ, the algorithm is active; when set to ÒOutÓ the algorithm is bypassed.
For the entire algorithm to be active, KB3 AuxFX must also be active.
Out Gain
The overall gain or amplitude at the output of the effect. For distortion, it is often
necessary to turn the output gain down as the distortion drive is turned up.
VibChInOut
When set to ÒInÓ the vibrato/chorus is active; when set to ÒOutÓ the vibrato/chorus is
bypassed.
Vib/Chor
This control sets the Hammond B3¨ vibrato/chorus. There are six settings for this effect:
three vibratos ÒV1Ó, ÒV2Ó, ÒV3Ó, and three choruses ÒC1Ó, ÒC2Ó, ÒC3Ó
Roto InOut
When set to ÒInÓ the rotary speaker is active; when set to ÒOutÓ the rotary speaker is
bypassed. By bypassing the rotary effect in KB3 FXBus, only the crossover Þlters are
bypassed. You must also bypass KB3 AuxFX to completely bypass the rotary speakers.
Likewise, for the entire rotary to be active, KB3 AuxFX must also be active.
Dist Drive
Applies a boost to the input signal to overdrive the distortion algorithm. When
overdriven, the distortion algorithm will soft-clip the signal. Since distortion drive will
make your signal very loud, you may have to reduce the Out Gain as the drive is
increased.
Warmth
A lowpass Þlter in the distortion control path. This Þlter may be used to reduce some of
the harshness of some distortion settings without reducing the bandwidth of the signal.
Lo Gain
The gain or amplitude of the signal passing through the rotating woofer (low frequency
driver. The control is also available in KB3 AuxFX.
Lo Xover
The crossover frequency for the low frequency driver. Lo Xover controls a lowpass Þlter.
Lo HP
A hipass Þlter to simulate the band-limiting of a speaker cabinet. The Þlter controls the
lower frequency limit of the output.
Hi Gain
The gain or amplitude of the signal passing through the rotating tweeter (high frequency
driver. The control is also available in KB3 AuxFX.
Hi Xover
The crossover frequency for the high frequency driver. Hi Xover controls a hipass Þlter.
Hi LP
A lowpass Þlter to simulate the band-limiting of a speaker cabinet. The Þlter controls the
upper frequency limit of the output.
