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.
