An often used expression in this manual is “focus”. For example, you can put a module parameter, a Slot,
a Morph group or a Patch Variation “in focus”. This simply means that the focused object is currently
selected and enabled for editing.

Just as in a traditional analog system, modules and parameters in Nord Modular G2 interact with each
other by means of signals being Patched from one place to another. In a typical analog system, these sig-
nals are represented by voltage ranging from e.g. -10 to +10 volts. The signal levels in the Nord Modular
G2 system are represented by “units”.
These units have nothing to do with the internal resolution of
the Nord Modular G2 system, which is 24-bit, but is used to more easily indicate levels in the system.
Nord Modular G2 uses three types of signals in its Patches:
• bipolar audio signals (-64 to +64 units)
• bipolar and unipolar control signals (-64 to +64 units, 0 to +64 units or 0 to -64 units)
• unipolar, high or low, logic control signals (0 or +64 units)
The illustration to the right shows the levels and the
polarity of the signals from the keyboard, an LFO, an
envelope, an audio signal and a logic signal.
The LFO is an example of a bipolar modulator. Bi-
polar means that it sends both positive and negative
levels (peak to peak –64 to +64 units). The keyboard
is another example of a bipolar modulator. The key
E4 (MIDI note number 64) represents 0 units in the
Nord Modular G2 system.
A normal ADSR envelope generator is an example of
a unipolar modulator. It will typically only modulate
in one direction, either positive or negative. In the
case of Nord Modular G2 ADSR envelopes, they can
be either unipolar or bipolar and have a range of 64
units.
The Clock generator is an example of a module
which sends logic signals. A logic signal is also a un-
ipolar signal but it has only two possible values, two states: low (0 units) or high (+64 units).
The types of output signals of each module in Nord Modular G2 will be described further on in this man-
ual using the definitions:

The resolution in the Nord Modular G2 system is 24 bits. This ensures a supreme audio quality. The
headroom of the audio signals in Nord Modular G2 is -12 dB for every sound source (Oscillator). This
