FILTER ZOOM – Key Tracking

The KEY control on the FILTER ZOOM page is identical to the KEY slider on the EDIT page. The Filter Tracking is a dedicated modulation control.  It determines to what extent the cutoff frequency will track the keyboard.  The higher the KEY value is set, the more the filter will open over the upper range of the keyboard and close in the lower ranges of the keyboard.

For example, if a low pass filter is loaded and the cutoff is set below 1.00KHz, the notes played below middle-C will become increasingly darker in tone, and keys above middle-C will be increasingly brighter.   At the minimum setting, higher and lower notes have no effect on the cutoff frequency.

 

KEY INVERT SWITCH

The KEY INVERT switch on the FILTER ZOOM page is identical to the KEY INVERT switch on the EDIT page. Key Tracking can be inverted simply by selecting the word “Key” below the control.  This switch will change to inverted text when Key tracking is inverted and the sonic result will be the opposite of standard Filter Key Tracking.
