Type

The type of the modifier can be selected by navigating through the list with the left or right
button, or by pressing on the label which displays the list of all available modifier types. For
a complete list and description of these modifier types, please refer to the specific chapter
at the end of the documentation.

Influence

A modifier is applied to a subset of partials. This selection (or partial influence) is controlled
through the parameters  

Center

,  

Spread

  and  

Falloff

. The center parameter controls the

center frequency of the modifier, the spread controls the frequency range of its influence
and finally the  falloff determines  how  this influence will  decrease to zero between the
center and the edge of the selection. The illustrations below present two modifiers with
decreasing falloff.

Specific Parameters

A modifier has two specific parameter knobs which control the type specific parameter 1 &
2. A display at the right of the knob presents the name of the parameter for the current
modifier type.

Keyboard Tracking

When keyboard tracking is set to 100, the modifier center and spread follow exactly the
note frequency. This corresponds to the modifier being applied the same on the wave form
partials regardless of the note pitch, which is usually what we want. When the tracking is
set to 0, the modifier center and spread are constant across the note range and fixed in
the spectrum. For instance, on an equalizer, this corresponds to a fixed peak or notch on
the spectrum just like a normal equalizer or formant filter would behave. For values of the
keyboard   tracking   under   0,   the   center   and   spread   increase   when   the   note   frequency
decreases.

Tuning

There are two knobs to define the basic pitch of the oscillator. The main one is used to
adjust the pitch in semi tones, from -48 to +48. The second one lets you finely tune the
oscillator in cents or hundredth of semi tones.
