Filter Tab

Node

Displays the selected node. You can use the arrow buttons to switch between nodes.

Frequency

Sets the frequency of the selected node.

Gain

Sets the gain of the selected node.

Filter On/Off

Activates/Deactivates the filter.

Filter Shift

Allows you to shift the filter curve in the frequency domain. This is similar to shifting the cutoff frequency of a classic synthesis filter.

Filter Scale

Scales the intensity of the Filter Shift.

With this parameter set to 0, Filter Shift and Filter Key Follow have no effect. With negative values, the effect of the Filter Shift settings is inverted.

Filter Key Follow

Allows you to adjust the Filter Shift parameter with the notes you play.

Set this parameter to a positive value to raise the frequencies of the filter nodes with notes above the Center Key. Set it to a negative value to lower the frequencies of the filter nodes with notes above the Center Key.

At a setting of 100, a note that is played one octave above the Center Key doubles the frequencies of all filter nodes, and a note one octave below the Center Key halves the frequencies. This means that the filter curve follows the pitch of the played note.

Center Key

Specifies the MIDI note that is used as the central position for the Key Follow function.

Low Cut

Allows you to adjust the damping of low frequencies. The higher the amount, the more low frequencies are cut.

Low Cut does not work like a classic filter with a fixed cutoff frequency. Instead, it takes into account the current frequencies in the sample. For example, if you set this parameter to 10%, the low frequencies that occupy 10% of the overall energy in the spectrum are removed. This is especially useful to remove low rumbling sounds that can become audible when you apply pitch shift towards higher pitches. At higher values, Low Cut can produce more drastic effects.

Slope

Allows you to set the slope of the filter, that is, to determine how fast frequencies within the low-cut range are attenuated.

Context Menu

Copy

Copies the selected nodes to the clipboard.

Paste

Pastes the copied nodes at the insert position.

Replace

Replaces the selected nodes with the nodes from the clipboard.

Duplicate

Duplicates the selected nodes.

Invert Gains

Flips the Gain values of the nodes around the vertical center of the selection. This way, you can turn a filter bump into a filter dip, for example.

Invert Frequencies

Flips the nodes around the horizontal center of the selection. This way, you can mirror the symmetry of an asymmetrical filter shape, for example, to turn a low-pass filter into a high-pass filter.
