PreampResp
Set this parameter On or O to enable or disable the preamp+expression pedal part of the KB3
model. Turning this On (the default) makes KB3 programs function like stock organs. The
expression pedal in this case is more than a volume pedal; it actually functions like a “loudness
control,” varying the frequency response to compensate for the ear’s sensitivity at dierent
volumes. In addition, the preamp provides a de-emphasis curve to compensate for the built-in
tone wheel volume pre-emphasis. Turning preamp response O emulates organs that have been
modied to have a direct out (before the preamp and expression pedal).
Leakage
Controls the level of the simulated crosstalk and signal “bleed” of adjacent tone wheels in the
model. This is provided to help “dirty up” the sound to make it a bit more realistic. A setting of
-96 dB gives the purest tones; other values add more simulated leakage. This level is scaled by the
drawbar levels, as well as the expression pedal level. The leakage level can also be controlled by
MIDI CC 90; value 0 = -96 dB, value 127 = 0 dB, values between 0 and 127 scale between -96 dB
and 0 dB. When using CC 90, the value displayed for the Leakage parameter will not change.
