Select the Custom LFO Shape Screen:
To create a custom LFO shape, you first need to get to the LFO Edit screen. Click on
the LFO shape LED display to display the shape pop-up menu. Select "Edit" at the
top of the popup menu. This will launch a screen where you can create custom LFO
shapes.
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-
