NORD MODULAR G2 V1.4x
• Factor range: x0.0248 to x38.055 relative to the input value on an unattenuated Pitch
input on the oscillator module. If the KBT button is on, the factor is relative to the
note played on the keyboard (or received via MIDI). If KBT is not active and no Pitch modulation is
present, the factor value is relative to the note E4.
• Partial range: 0 Hz up to 5.15 Hz (knob position 0 to 31) and 1:32 upto 64:1 (knob
position 32 to 127) relative to the input value on an unattenuated Pitch input on the
oscillator module. If the KBT button is on, the partial is relative to the note played on the keyboard (or
received via MIDI). If KBT is not active and no Pitch modulation is present, the partial value is rela-
tive to the note E4.
The lowest value in Partial mode is 0 Hz. When an oscillator is at 0 Hz it actually stops oscillating, which
causes it to stop generating any sound on its own. At 0 Hz the output will be a DC level (steady level)
with a value that depends on both the waveform and the phase position in the waveform at the moment
when the oscillator was stopped (was set to 0 Hz). This 0 Hz position can be useful when applying
frequency modulation, it presents a special case of linear FM which is used when modulating non-
sinewave waveforms like a triangle waveform frequency modulated with a pulse waveform. Bipolar linear
frequency modulation of a 0 Hz signal will generate both positive and negative - 180 degrees phase
shifted - frequencies and create very interesting timbres. Oscillator B and C plus the two Shape
Oscillators feature FM inputs. In these oscillators, you can set the Partial to 0 Hz and then frequency
modulate the signal by selecting 'FM Trk' and connecting a modulator signal to the FM input. This
technique can produce a virtually unlimited amount of new waveshapes.

The Sync input is used for synchronizing the oscillator with a control source, which could be
another oscillator, an LFO or the keyboard gate signal. Synchronization forces the oscillator to
restart its waveform cycle, in sync with the signal of the controlling device. The oscillator will restart
whenever the syncing signal on this input goes from a negative to a positive amplitude value. Waveforms
with a flank, like the sawtooth or pulse waveforms, will restart at a flank, while waveforms without a flank
like the sine and triangle waveforms will restart at a zero value.
The pitch of the controlling oscillator will interact with the controlled oscillator pitch. For a traditional
synthesizer sync-sound, start with two oscillators set to the same pitch and connect only the synced
oscillator to an output. Turning the tuning knob or modulating the pitch of the sync-controlled oscillator
will produce radical changes in the timbre. In general the synced oscillator is tuned higher as the syncing
