Shape Mod
This knob governs the amount of modulation applied to the Shape
parameter . The Shape parameter can be modulated by the LFO or the
Mod Envelope .
Waveform selector button
The Waveform selector button is used to cycle through the different
algorithms and categories . Turn the Waveform selector dial beneath
the LED display to choose the specific waveform or algorithm that you
wish to use .
Analog style waveforms
The Analog waveforms Triangle, Sawtooth and Pulse have each four
variations that can be selected with the selector dial, summarized in the
table .
Display
Waveform
-----
Standard Triangle,
Sawtooth or Pulse .
ShP
A shapeable
waveform .
dtn
A dual de-tuneable
waveform .
Snc
A synched wave-
form .
When you change waveform, the name of the currently selected wave-
form is shown briefly in the LCD .
Triangle
The triangle waveform has only odd numbered and not very strong
harmonics .
Sawtooth
The sawtooth wave contains all harmonics and is the richest of the
available waveforms . It is suitable for all sorts of sounds .
Explanation
A plain waveform .
Tri: the Shape control emphasizes the
available harmonics in the spectrum .
Saw: the Shape control shifts the
phase of two super imposed sawtooth
waves up to a maximum 180 degrees
shift, which creates a perceived one
octave shift .
Pulse: the Shape sets the width of the
pulse .
Two oscillators with adjustable relative
pitch . Shape knob range is +/- 12
semitones .
An oscillator with adjustable pitch off-
set, hard-synced by a second oscillator .
Pulse
The pulse wave contains only odd numbered harmonics (3, 5, 7 etc .)at
50% pulse width (square wave) . This waveform is special in that its
harmonic content can be varied continuously, by adjusting the pulse
width . The examples below have 50%, 10% and 5% pulse width .
The Shape knob controls the pulse width of the pulse wave, from 50%
(square wave) to 1% if the ShP wave is selected . You can modulate the
Shape using Morph (see page 19), with the LFO or the Mod Envelope .
This waveform is suitable for many type of sounds and has a more
"hollow" character than the Sawtooth wave .
Noise
There are two samples available of white and pink noise in the Sample
selection in the factory sound bank of the Nord Stage 2 .
Oscillator Sync waveforms
The Saw, Pulse and Triangle waveforms can be synchronized, if the
Snc option is selected . Oscillator Synchronization means that you use
the signal from one oscillator to restart another oscillator . Nord Stage
2 has a "hidden" sync oscillator for the waveforms with this option .
Oscillator sync is very useful for generating lead lines with classic "hard
sync" sounds . When sync is applied, the basic pitch of the oscillator is
locked to that of the sync oscillator . When you vary the relative pitch of
the synchronized oscillator with the Shape knob, this will be perceived
as a change in timbre, with a frequency spectrum with deep resonance
in the oscillator's harmonics .
