Vibrato/chorus into distortion into rotating speaker into cabinet

PAUs: 7 for full working effect
4 for KB3 FXBus
3 for KB3 AuxFX
The KB3 FXBus and KB3 AuxFX algorithms contain multiple effects designed for the Hammond B3
emulation (KB3 mode). For correct operation both effects must be running at the same time with the
output of KB3 FXBus feeding the input of KB3 AuxFX. The two algorithms work as one algorithm which
use all the available KDFX resources. While the input to KB3 FXBus is stereo (which gets summed to
mono) and the output from KB3 AuxFX is stereo, the signals between the two algorithms are the low
frequency (left) and high frequency (right) signal bands used to drive the lower and upper rotary speakers.
It is possible to run these two algorithms as independent effects, but the results will be somewhat unusual,
and therefore not generally recommended.
These effects are the Hammond vibrato/chorus, amplifier distortion, and rotating speaker (Leslie
emulations. Each of these effects may be turned off or bypassed, or the entire algorithm may be bypassed.
To bypass the rotary, the switches in both KB3 FXBus and KB3 AuxFX must be set to Out.

The first effect in the chain is the Hammond vibrato/chorus algorithm. The vibrato/chorus has six settings
which are the same as those used in the Hammond B3®: three vibrato (V1, V2, V3) and three chorus (C1,
