Key Tracking

The Filter Key Tracking knob 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.

Range 0 to 127

FILTER KEY TRACKING INVERT SWITCH

Key Tracking can be inverted simply by selecting the word “KEY” below the control. The button’s label text will become inverted and the sonic result will be the opposite of standard Filter Key Tracking.

TIP: The Resonator +/- filters are tuned to respond to key tracking.

• 1) Put the Filter Cutoff at the default (50) value.%
• 2) Turn the Key Tracking knob all the way up.
• 3) Invert the key tracking with the switch.

At these settings, the Resonator +/- filters will track the pitch when played above middle C (although we intentionally detuned it a few cents). And with some timbres there can be surprising pitches on certain notes.
