Filter Override

The filter type of the first voice in the preset (on the currently selected channel) is

shown in this display. If you change the filter type in this field, ALL the voices in the

preset will change to the filter type you select. When the display reads, - Not Set - the

filters programmed in each voice will be used. The filters may be set differently for each

voice.

You can choose from 55 different filter types or choose “No Filter”, which bypasses the

filter section.

The frequency response curve of the filter is accurately shown in the display.

Frequency is shown on the horizontal axis, with amplitude on the vertical axis.

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.
