the keys to hear the difference. DonÕt forget to check out the differences with the
drawbars at varying positions.
2. Press the >> button twice to get to the Chorus/Vibrato Switch parameter. This
parameter and the next parameter, Chorus/Vibrato are identical to the settings you can
choose with the SW2 and SW3 buttons, which we discussed in the Intro Tutorial. If you
change the value in the display, the button will change, and vice versa.
3. Press the >> twice button to get to the Rotary Speed parameter. Like the
Chorus/Vibrato parameters, this can also be set by a button - in this case the SW1
button.
4. Press the >> button to get to the Drawbar Mode parameter. This has two possible
values Ð Preset and Live. If it is set to Preset, then you can choose the settings for each
drawbar with the next set of parameters. If you set it to Live, then whatever the physical
settings of the Drawbars are will be the setting you hear when the program is selected.
KB3 program 080 Live Drawbars is set this way, while all the other stock KB3 programs
are set to Preset.
5. Press the >> button again. Here you see the settings for each of the 9 drawbars. In this
case they are all set to a value of 8, which is fully out (just as you might expect from the
name of the program). Each drawbar can be set to a value between 0 and 8. You can use
the sliders to change the values, or use the >> and << buttons to scroll to a specific
drawbar and then change it with the wheel or + and Ð buttons. Remember that the
Drawbar Toggle button switches the sliders between the first four and second four
drawbars. The mod wheel controls the 9
th
drawbar.
6. Press the >> button enough times to get to the next parameter, Drawbar Steps. In a
real tone wheel organ, the drawbars have 9 discreet steps, numbered from 0 through 8.
As you go from one value to another there is a distinct change in the amplitude for that
drawbar. If you set this parameter to Normal, it will mimic those nine steps. If it is set to
Smooth, then there are actually 127 different values for the slider (the same as a normal
MIDI controller would have) and you will have a smoother transition of amplitude as
you move the slider up and down. The Display still shows the values as 0-8, even
though the transition is smoother.
7. Press the >> button to get to the Preamp Response parameter. On a real B3, the
volume pedal is connected to a preamp. The pedal in this case is more than a volume
pedal; it actually functions like a Òloudness control,Ó varying the frequency response to
compensate for the earÕs sensitivity at different volumes. In addition, the preamp
provides a de-emphasis curve to compensate for the built-in tone wheel volume pre-
emphasis. But some people preferred to modify the organ to have a direct out that
skipped this preamp.
On the PC2 if this parameter is set to On, then it mimics the behavior of the Preamp on
a regular B3. If it is set to Off, it works just like a direct out. You should note that
turning this off will mean that the Expression pedal will no longer control the volume.
(You could however, still control volume with the pedal, by putting the KB3 program
into a Setup and assigning the pedal to Controller #7, MIDI Volume).
8. Press the >> button to get to the Leakage parameter. As mentioned earlier, this allows
you to emulate the leakage (Crosstalk and signal ÒbleedÓ) between adjacent tone wheels,
which is common on tone wheel organs. This helps to Òdirty upÓ the sound and make it
more realistic. A value of Ð96dB will give you the purest tone, while a value of 0dB will
