Filter tracking
The pitch of the note played can be made to alter the cut-off frequency of the filter. This
relationship is governed by the setting of the Key Tracking control
42
. At the maximum
value (127), the filter cut-off frequency moves in semitone steps with the notes played
on the keyboard – i.e., the filter tracks the pitch changes in a 1:1 ratio. This means that
when playing two notes an octave apart, the filter cut off frequency will also change by
one octave. At minimum setting (value 0), the filter frequency remains constant, whatever
note(s) are played on the keyboard.
When using filter resonance as an additional oscillator, set Key Tracking
to maximum (127) to allow the filter to be played ‘in tune’.
Overdrive
The filter section includes a dedicated drive (or distortion) generator; the Overdrive
control
37
adjusts the degree of distortion treatment applied to the signal. The drive is
added before the filter.
Peak does not have a dedicated Filter menu, but two further Filter-related
parameters – Filter Post Drive and Filter Divergence - are also
available for adjustment in the Voice menu. See page 29.
