Attack

Attack is the time it takes for the
modulation envelope to reach the
maximum modulation level . This
envelope phase begins when you
press a key .
Range: 0.45 ms to 45 s

Decay/Release (Dec/Rel)

Decay begins after the attack phase is completed . It is the time it takes
for the modulation envelope to fall back to zero modulation again .
If A/R mode is active, the release phase will begin when the key is
released .
If Dec/Rel is turned fully clockwise, the decay or release time will be
infinite .
Infinite Decay or Release times acts a Sustain levels on all destina-
tions with one exception: Osc 1 and Osc 2 pitches are not modu-
lated at all by a Mod Envelope Release that is set to infinite.
Range: 3.0 ms to 45 s, Infinite

Destination selector

Select the destination for the modulation from the
envelope . The modulation amount will be summed
with any other modulation that occurs at the
destination .

Description
Chapter7paNeLrefereNCe
M
When the modulation envelope is used to modulate oscillator
pitch in A(S)R-mode, the sustain phase of the envelope will be the
nominal pitch of the oscillator.

AR mode

Selecting A/R changes the Attack/Decay envelope to a Attack/(Sus-
tain)/Release envelope .

Impulse Morph Sync (Imp Sync)

The Modulation Envelope will be restarted when an Impulse Morph but-
ton is pressed if Impulse Sync is enabled .
M
Enabling Imp Sync makes the Modulation Envelope monophonic.
Amount
Amount sets the strength of the envelope modula-
tion . At the center detented 12 o'clock position, the
modulation is zero . Turn left to get negative modula-
tion, turn right to get positive .

Oscillators

The oscillator is the foundation of the sound in a synthesizer . It pro-
duces the waveform with a harmonic content . This important property
of the sound can be shaped and/or modulated later in the signal path .
There are two oscillators in the Nord Lead 4 . You can mix the output
of the two, and detune them for a fatter sound . One oscillator can also
modulate the other, creating very complex and constantly changing
harmonic structures .

Oscillator 1

Triangle
The triangle waveform is quite soft in its character with only odd num-
bered and not very strong harmonics .
Sawtooth
The sawtooth waveform produces a very rich sound that contains both
even and odd numbered harmonics .
Pulse
The pulse waveform has a hollow character . At a 50% width it pro-
duces only odd numbered harmonics . If the width becomes narrower,
more odd and even numbered harmonics will be present .
The pulse have three available settings, one with a 50% width that can
be modulated by LFO 1 (PWM) and two fixed widths, 10% and 33% .
