Factory Performances 1.G5-1.H7, holds reproductions of 13 classic organ sounds. By using layers of sev-
eral Slots, combined with a special “pseudo-additive” synthesis, Clavia have filtered out a minor number
of “partials” from each Oscillator and combined them into different drawbar configurations, successfully
emulating the sound of drawbar organs such as the classic B-3.

To make best use of the organ emulations and their special features, some knowledge about the original
instruments might be of use. Briefly, the following building blocks were combined to create the drawbar
organ sounds:

These are click-stopped “sliders”, usually nine, each one controlling the volume of a certain partial in the
organ tone. The partials are indicated in the classic pipe organ way, referring to the length of the organ
pipes. Thus, the standard drawbar configuration is (from the bottom up):

By using the drawbars to change the balance between the partials, the harmonic content of the organ tone
can be changed.
can be changed.
In the Nord Lead 2X organ sounds, the oscillators are used to generate the partials. In some cases, there
is a direct “one oscillator - one drawbar” relation; other sounds use more complex waveforms to simulate
up to three combined partials with one oscillator. Usually, the oscillators in each slot are paired, so that
Oscillator 1 generates the lower partial(s) and Oscillator 2 the higher. Therefore, you can give the sound
more bottom or edge, by changing the Oscillator balance with the Mix knob for each Slot.

To add some attack to the sound, most classic organs feature Percussion - an accent-like tone with fast
attack, short decay and no sustain. Usually the pitch of the Percussion tones are 4’ or 2 2/3’ (or both
mixed), in effect replacing the corresponding drawbar partials. Some of the Nord Lead 2X organ sounds
make use of Percussion in Slot B. You can vary the balance between the two Percussion pitches with the
Mix knob, and also change the Decay time of the Percussion tone to make it fit your playing style.

Though not an intended feature on the classic organs, the short, non-pitched click noise when keys are
pressed has become a popular characteristic. In the organs, the sound came from oxidation on the key
switches; in the Nord Lead 2X you can add or remove the click as desired. All of the Nord Lead 2X organ
Performances has the click sound on Slot D, although it is by default turned off for some of the sounds.

This inharmonic, thin sound is also an unintended artifact, generated by leakage between the tonewheels
in the organs. It is included in some of the Nord Lead 2X organ sounds, adding even further realism.
