Introducing The Envelope
The ENVELOPE will allow you to shape the FILTER CUTOFF, the VCA(output volume),
and other parameters via the MOD MATRIX.
Setup the BASIC PATCH again and we will experiment with the ENVELOPE and the
FILTER CUTOFF.
Now, change the FILTER and ENVELOPE setting to be the same as you see in Figure
10.
Figure 10
The BASIC PATCH has the SUSTAIN value at the maximum setting which basically turns
the envelope on full. Start off by moving SUSTAIN to the minimum setting and the DECAY
slider to the maximum setting.
To have the ENVELOPE affect the FILTER CUTOFF, you need to turn up the ENV Amt knob
in the FILTER section. The ENV Amt knob can go either positive or negative. Let’s go with
positive for now.
You will want to turn the CUTOFF knob down to hear the effect. In
Figure 10, we have
the RESONANCE control up part way to make the effect more interesting.
Press a key and listen to how it seems that the FILTER CUTOFF is being moved by itself.
Reducing the DECAY slider will make the effect of the filter sweep go faster.
If the DECAY is set too low, it is moving the CUTOFF so fast that you might just hear a
click.
