Filter Controls
You can choose from 53 different filter types or choose “No Filter”, which bypasses the
filter section.
Most of the filters have two parameters: Frequency (or Morph) and Resonance (Q, Gain,
Body Size). These two parameters can be continuously varied during the note (choose
realtime resonance).
The frequency response curve of the filter is accurately shown in the display as you
change the initial filter settings. Frequency is shown on the horizontal axis, with
amplitude on the vertical axis.
High values of Q or resonance, amplify frequencies near the cutoff or center frequency.
In a swept EQ filter, gain controls the amount of boost or cut. In a phaser or flanger,
resonance determines the depth of the effect. In the vocal filters, body size determines
the apparent size of the mouth cavity.
You will notice an increase in voice count when the filters are bypassed as the filters steal
cycles from your computer’s CPU. 12th order filters use more CPU and therefore
decrease the maximum voice count.
