Filter
The Filter is the most important section for shaping the overall timbre of the sound. Nord Lead’s filter can
be switched between various
types . It has the standard main Frequency and Resonance control. The At-
tack, Decay, Sustain and Release parameters make up the Filter Envelope. These, together with the En-
velope Amount knob, can be used to make the Filter frequency vary as the sound progresses, when you
press and hold a key.
For an introduction to filters, see page 79.
Filter Type
LP 12dB: LP stands for low-pass. A low-pass filter lets low frequencies pass and cuts out higher frequen-
cies. Exactly which frequencies get cut out is determined by the Filter Frequency setting (and various oth-
er controls, as described below).
In the 12dB low-pass mode, the filter has a gentle roll-off curve (12dB=2poles). This mode leaves more
harmonics than the 24dB variation discussed below. This type of filter has been used in various Oberhe-
im synthesizers and others.
