Creating a New LFO Shape / Adding “Points” to the Waveform:

Creating a new shape is really pretty easy. To create a new shape you first need to

add a new “point” in the waveform (you’ll notice that the starting shape is a sine

wave with three points: one at each end and one in the middle at the top). To add a

new “point”, simply click anywhere on the green waveform; this will insert a new

point. To remove a point, hold down the option key while clicking on it with the

mouse. To change the shape of the wave, click on the new point and drag it up, down

sideways etc. You will see that the shape of the green waveform line will change

based on where you position the point. Letting go of the mouse will position the

point where you left it. You can create as many points on the waveform you like and

use the “grab/move” operation to reposition any of the points. This process allows

you to create some REALLY complex wave shapes.

Smoothing:

The “Smoothing” control allows you to “round out” the edges in the wave shape

between the points. When smoothing is set to zero (no smoothing), the waveform will

have a stair-step appearance and will jump abruptly from point to point. By increas-

ing the “Smoothing” control you can decrease the abrupt changes between the

points and smooth out the transitions between points by varying amounts. When set

to its maximum value the waveform will be completely smooth.

Smoothing Mode:

The Smoothing Mode determines the “shape” of the smoothing that will be used to

connect the points. This further increases the variety of waveforms you can create

within the LFO Shape Editor. The Smoothing Mode choices are as follows:

Linear: Points are connected using straight lines

Sine: Produces a sinusoidal-like waveform, which is very smooth.

Exp: Produces a “scooped”, curved waveform where the curve is not even but kind of

“rises quickly”, similar in shape to those used in an exponential analog ADSR

envelope

Sym: Produces a curved shape that is even and symmetrical.

Naming and Saving Custom Waveforms:

Once you have edited a shape and created a new LFO waveform, the Shape LED dis-

play will show the word “custom” indicating that a new shape has been created. To

keep your wave shape handiwork from going to data-heaven, you need to save it and

give it a name. Pressing the Save button allows you to name and save the waveform

for future use. Once saved, the new shape will appear in the “Shape” pop-up menu

under the Preset menu entry and can be selected as previously described.
