Filter Shape• LP 24, 18, 12, and 6 are low-pass filters with 24, 18, 12, and 6 dB/oct. Fr
 equencies above the cutoff are attenuated.
• BP 12 and BP 24 are band-pass filters with 12 and 24 dB/oct.  Frequencies below and above  the cutoff are attenuated.
• HP6+LP18 and HP6+LP12 ar e combinations of a high-pass filter with 
6 dB/oct and a low-pass filter wi th 18 and 12 dB/oct, respectively 
(asymmetric band-pass filter). Frequencies below and above the cutoff 
are attenuated....

Fixed
•If Fixed is activated and you move selected nodes on the time axis, only the 
selected nodes are moved.
•If  Fixed is de
 activated, all nodes that follow the edited nodes are also moved.
Snap
You can select a second envelope to be displayed in the background of the edited 
envelope. If Snap is activated and you ch ange the position of nodes, they snap to 
the nodes of the envelope that is shown in the background.
• To specify the envelope for the background, open the...

Adjusting the Level Parameter
The Level  parameter specifies the amplitude of the envelope at the position set by 
the  Time  parameter.
•To set the Level  
 parameter, select the nodes that you want to adjust and enter 
a value in the  Level field.
• You can also adjust the  Level 
 parameter in the graphical envelope editor by 
dragging the selected nodes up or down, to decrease or increase the levels.
For a higher resolution, hold [Shift] while moving the nodes.

Adding Nodes Using the Fill Function
The Fill function allows you to add multiple envelope nodes after the selected 
nodes.
PROCEDURE
1. On the pop-up menu to the right of the  Fill button, select the number of nodes 
that you want to add.
2. In the graphical envelope editor, select  the node after which you want to add 
nodes.
If several nodes are selected, the new nodes are inserted after the last selected node.
If the  Fixed  fun
 ction is deactivated, the added nodes are...

3. To use triplet note values, activate the T button.
• Envelope nodes that do not exactly match a note value display the closest note 
value.
• Nodes that exactly match a note value are indicated by a red dot inside the  handl
 e of the node. This is useful if  you switch the grid between triplets and 
normal note values, for example. The trip let nodes still indicate that they match 
a note value, even if the grid shows normal note values.
4. You can also enter note values...

3. The loop is indicated by the green region in the graphical envelope editor. Specify the loop start and end by dr agging the borders of the region.
The loop region can only be set up in the decay phase of the envelope.

Key Range
Activate this button to specify the key  range
  of the sample, that is, the range 
over which it is mapped chromatically to pads.
• Lo
w Key  specifies the first key for the mapping.
• High Key  specifies the last key for the mapping.

SegmentsHere, you can select which phases of the envelope are affected by the  Time 
Velo
 city parameter.
• A
ttack  – The velocity affects the attack only.
• Attack + Decay  – The velocity affects all phases until the sustain.
• Decay  – The velocity affects all phases until the sustain but without the 
attack.
• Attack + Release  – The velocity affects the attack and the release 
phases.
• All – The velocity affects all phases.
Level Velocity Curve You can select the curve...

2. Optional: Set up the Fixed Pitch parameter.
•If Fixed Pitch  is activated, the sample is played with its original pitch on all the 
pads in the key range.
•If  Fi
xed Pitch  is deactivated, the sample is played chromatically within the key 
range.
RESULT 
The samples are mapped to the pads. An ic on with two notes indicates which pads 
play a chromatically mapped sample.

• 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 wi th 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 combinations of a high-pass filter  with 6 and 12 dB/oct and a band-reject filter with 12 dB/oct....

Level Velocity Curve
You can select the curve type to specify how the incoming velocity translates 
to th
e level of the envelope. The charact eristic of each curve is displayed by 
a small icon.
