Filter Shape

• LP24, 18, 12, and 6 are low-pass filters with 24, 18, 12, and 6 dB/oct. Frequencies above the cutoff are attenuated.

• BP12 and BP24 are band-pass filters with 12 and 24 dB/oct. Frequencies below and above the cutoff are attenuated.

• HP6 + LP18 and HP6 + LP12 are combinations of a high-pass filter with 6 dB/oct and a low-pass filter with 18 and 12 dB/oct, respectively, also known as asymmetric band-pass filters. Frequencies below and above the cutoff are attenuated. Attenuation is more pronounced for the frequencies above the cutoff.

• HP12 + LP6 and HP18 + LP6 are combinations of a high-pass filter with 12 and 18 dB/oct and a low-pass filter with 6 dB/oct, also known as asymmetric band-pass filters. Frequencies below and above the cutoff are attenuated. Attenuation is more pronounced for the frequencies below the cutoff.

• HP24, 18, 12, and 6 are high-pass filters with 24, 18, 12, and 6 dB/oct. Frequencies below the cutoff are attenuated.

• BR12 and BR24 are band-reject filters with 12 and 24 dB/oct. Frequencies around the cutoff are attenuated.

• BR12 + LP6 and BR12 + LP12 are combinations of a band-reject filter with 12 dB/oct and a low-pass filter with 6 and 12 dB/oct, respectively. Frequencies around and above the cutoff are attenuated.

• BP12 + BR12 is a band-pass filter with 12 dB/oct plus a band-reject filter with 12 dB/oct. Frequencies below, above, and around the cutoff are attenuated.

• HP6 + BR12 and HP12 + BR12 are a combination of a high-pass filter with 6 and 12 dB/oct and a band-reject filter with 12 dB/oct. Frequencies below and around the cutoff are attenuated.

• AP is an all-pass filter with 18 dB/oct. Frequencies around the cutoff are attenuated.

• AP + LP6 is an all-pass filter with 18 dB/oct combined with a low-pass filter with 6 dB/oct. Frequencies around and above the cutoff are attenuated.

• HP6 + AP is a high-pass filter with 6 dB/oct combined with an all-pass filter with 18 dB/oct. Frequencies around and below the cutoff are attenuated.

Distortion Type

• Off deactivates the filter section.

• Tube Drive adds warm, tube-like distortion. You can set the amount of tube drive by adjusting the Distortion parameter.

• Hard Clip adds bright, transistor-like distortion. You can set the amount of hard clipping by adjusting the Distortion parameter.

• Bit Red (Bit Reduction) adds digital distortion by means of quantization noise. You can adjust the bit reduction by adjusting the Distortion parameter.

• Rate Red (Rate Reduction) adds digital distortion by means of aliasing. You can adjust the rate reduction by adjusting the Distortion parameter.

• Rate Red KF adds digital distortion by means of aliasing. In addition, Key Follow is used. The rate reduction follows the keyboard, so the higher you play, the higher the sample rate.

Cutoff

Controls the cutoff frequency of the filter.

Resonance

Emphasizes the frequencies around the cutoff. At higher settings, the filter self-oscillates, which results in a ringing tone.

Distortion

Adds distortion to the signal, according to the selected Distortion Type.

Cutoff Key Follow

Adjusts the cutoff modulation using the note number. Increase this parameter to raise the cutoff with higher notes. At 100%, the cutoff follows the played pitch exactly.

Center Key

Specifies the MIDI note that is used as the center position for Cutoff Key Follow.

Filter Envelope Amount

Controls the cutoff modulation from the filter envelope.

Filter Envelope Velocity

Controls the cutoff modulation from velocity.

Envelope Parameters

Envelope Mode

• Select Sustain to play the envelope from the first node to the sustain node. The sustain level is held for as long as you play the note. When you release the note, the envelope continues with the stages following the sustain. This mode is ideal for looped samples.

• Select Loop to play back the envelope from the first node to the loop nodes. As a result, the loop is repeated for as long as you hold the key. When you release the note, the envelope continues playing the stages that follow the sustain. This mode is ideal for adding motion to the sustain of the envelope.

• Select One Shot to play the envelope from the first to the last node, even if you release the key. The envelope has no sustain stage. This mode is ideal for drum samples.

• Select Shaper to use the envelope as a modulator that allows you to create freely programmable cyclic modulations. To ensure a seamless cycle, the start and end node levels are linked.

  Note

  The Filter envelope continues to be played in a loop after releasing notes, which makes it possible to use the modulation in the Release phase of a note.

Edit

Allows you to edit single or multiple nodes.

Erase

Allows you to delete envelope nodes.

Draw

Allows you to insert a predefined envelope shape.

You can enter shapes by clicking or by clicking and dragging.

• Click on the envelope display to insert the selected shape with its predefined length. If Sync to Host is activated, the shape is inserted at the nearest grid position. If you repeatedly click at the same position, the shape is inserted multiple times.

• Click and drag to insert the shape in the covered drag area. If Sync to Host is activated, the start and the end nodes of the shape snap to the grid, and all nodes in between are scaled relative to the overall length of the shape. After the shape is inserted, all nodes remain selected. This allows you to switch back to the Edit tool for further editing of the shape.

With Fixed Mode activated, the inserted nodes replace all nodes that cover the current time range. With Fixed Mode deactivated, all consecutive nodes are moved to the right.

Paint

Allows you to paint in a predefined envelope shape. The shape is inserted with its predefined length.

If Sync to Host is activated, the length is quantized to the grid. The level of the shape is determined by the vertical mouse position. This allows you to draw perfectly tempo-synchronized, sequential shapes with an added overall level progression.

Select Shape Preset

Allows you to select the shape that is used when entering nodes with the Draw or the Paint tool. A shape consists of multiple nodes making up a progression that can be used when creating your envelopes. The predefined factory shapes are available via the Factory tab. You can also create your own shapes and add them to the User tab. Up to 48 shapes are available per tab.

Save Shape Preset

Allows you to save the current envelope shape as a custom shape. You can add up to 48 custom shapes to the User tab.

Sync to Host Tempo

Allows you to synchronize the envelope to the tempo of your host application.

Grid

Allows you to set the grid for the envelope display, in note values.

Fixed Mode

• With Fixed Mode activated, only the selected nodes are moved when you move a node on the time axis.

• With Fixed Mode deactivated, all subsequent nodes are moved as well when you move a node.

Show Waveform

Shows the sample waveform in the envelope editor.

Snap

If Snap is activated and you change the position of nodes, they snap to the nodes of the guide envelope that is shown in the background.

Show Guide Envelope

From this pop-up menu, you can select a second envelope to be displayed in the background of the edited envelope.

• If Snap is activated when you move nodes, they snap to the guide envelope.

Select Node

Displays the active envelope node. To select a node, enter its number in the field. To step through the nodes, use the Previous Node/Next Node buttons.

Time

Specifies the period of time between two nodes. Depending on the Sync mode, the Time parameter is displayed in milliseconds and seconds, or in fractions of beats.

Note

The fraction is always reduced to the smallest possible value. 2/16 is displayed as 1/8, for example.

Level

Specifies the amplitude of the envelope at the position set by the Time parameter.

Curve

Allows you to adjust the curvature between two nodes from linear to logarithmic or exponential behavior.
