Programming the filter envelope (Filter EG)
You can create an envelope to vary over time the cutoff frequency of the
filters on the selected oscillator.
▪ Go to the Sound > Filter > EG page.
You can see the shape of the envelope in the diagram on top of the page.
Setting the Filter EG levels and times
Filter EG can be programmed by setting the Level and Time parameters of
the envelope segments.
The result will depend on the filter type. For example, with the Low Pass
Resonance filter, positive (+) values of EG Intensity will cause the tone to be
brightened by positive (+) levels, and darkened by negative (–) levels.
Also, the effect of these settings on the filter cutoff frequency depends by
the Velocity and Intensity parameters of the Filter > Modulation page.
