Waveform Selector

The first three waveform alternatives for Oscillator 2 are identical to the corresponding waveforms of Oscillator 1 (see above). Oscillator 2 also has another waveform, the Noise:

Noise, Noise colour and Sync Wave

With Noise selected, Oscillator 2 produces noise rather than a pitched waveform. The exact color (frequency content) of the noise can be adjusted with the Oscillator 2 SEMITONES knob. The further you turn the knob clockwise, the brighter the noise. All the way to the right, its frequency characteristics is very close to that of white noise (where all frequencies are represented with equal energy).

‘White noise’ contains all frequencies at equal energy levels

Note that the sound of the noise is also affected by the filter setting (as all other sound from the Nord Lead 2X). If the filter frequency is turned down, adjusting Noise color might not have the expected effect.

If Sync is activated (see page 43), selecting Noise will produce very special signals with non-transposed formant spectrum with strong “body resonance” characteristics. The reason ‘synched noise’ works at all is that it’s the same series of frequencies that are synched (repeated over and over). In a traditional analog system this function wouldn’t work since the noise is totally random. In ‘Sync wave’ mode the SEMITONES knob works as a “waveform selector”. Turning the knob will change the harmonic content of the sound. The Sync wave selection is not continuous, but stepped, in steps that correspond to the octave markings around the SEMITONES knob.
