The global Glide knob acts like an overall glide offset. The amount of glide determines the point

within a step at which the XLFO starts to interpolate to the value of the next step. The global Glide

value is added to the glide value for individual steps to arrive at the final glide value for each step.

The final glide value is limited between 0 (no interpolation) and 1 (full interpolation). Because the

global Glide value can range from -1 to 1 it can completely overrule the individual step glide values

at the extreme settings. It is also a modulation target which allows for very cool effects.

Phase offset

In the step editor you can see a triangular shape. The vertical line of the shape indicates the

beginning of each cycle. You can move this triangular shape, and thus change the beginning of a

XLFO cycle. This phase offset is a modulation target, so when the XLFO frequency is set to 0, you

can use another modulator to cycle through the different steps. Tip: Like with knobs

, you can

Ctrl/Command-click on the phase offset slider to reset it.

To delete an XLFO, move the mouse over it and click the remove button

in the top right corner. Below

the source, next to the source name, the Presets button

provides access to the XLFO section presets.

By default, the XLFO starts with two steps that make a sine wave. You can customize this by overwriting

the predefined Default section preset using the Save As Default command from the preset menu.

Editing Steps

You can shape the waveform of the XLFO in almost any way you want by editing the individual steps.

Drag a step up or down to change the value for the step.

Click a step to select it.

Hold down Ctrl (Command on Mac) and click a step to select multiple steps. Hold down Shift and

click a step to select a consecutive range of steps.

Click next to a step to deselect all steps.

Click the + button at the end of all steps to add a new step. The new step is added to the right of

the selected step, or at the end of all steps.

Click the - button at the end of all steps to remove the selected steps. If no steps are selected, the

last step is removed.

If one or more steps are selected, the XLFO expands to show the step interface where the parameters

for the selected steps can be edited:

Random

The Random button enables random values for this step. If enabled, the XLFO will use a new

random value for the step each time it encounters it. The display also changes to show that the

value is chosen at random (see step 3 in the screen shot above).

Value

The Value knob adjusts the value of step. This is the same as dragging the step up and down,

except that with multiple selected steps, the value of all steps is set to the same value. In contrast,

when you drag multiple selected steps, the relative distance is kept the same.

Curve

The Curve button selects the curve that is used to interpolate to the next step when the final glide

value is higher than 0: Linear, Sqr, Sqrt and Sine.

Glide

The Glide knob sets the per-step glide value. This is combined with the global glide value to

determine at which point the XLFO starts to interpolate towards the next step.

To start exploring the many sound-shaping possibilities, start with an XLFO that modulates

a Drive knob

or Crossover Frequency to make the sound change over time. You'll be amazed by the many possibilities.

Have a look at the presets to see the XLFO in many different setups to get an idea of what it can do for

you and start creating your own sequences!
