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 Explanation
-----
Standard Triangle,
Sawtooth or Pulse.
A plain waveform.
ShP
A shapeable
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.
dEt
A dual de-tuneable
waveform.
Two oscillators with adjustable relative
pitch. Shape knob range is +/- 12
semitones.
Snc
A synched wave-
form.
An oscillator with adjustable pitch off-
set, hard-synced by a second oscillator.
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.
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 (PWM). 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 99% if the ShP wave is selected. You can modulate
the Shape using Morph (see page MORPH), 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.
 When using Oscillator Sync, it can be very useful to have the
Shape amount(s) modulated from any of the Morph assign
