the Patterns are in Appendix A, page

Return to the basic setting shown

in figure 2, which features pattern 2.

As you play your instrument through

the MIDI MuRF, pay attention to

the sound of the effect and how it

corresponds to figure 10. You should

hear the Animation "stair-stepping"

through the filters. Turn the RATE control up and down and notice how

the pattern speeds up and slows down.

Now it’s time to explore the ENVELOPE Control - one of the most

powerful parts of the MIDI MuRF.

1) With the ENVELOPE Control set at 2, you should hear each of

the filters with a sharp attack and a decay that fades out smoothly but

quickly.

2) Turn the ENVELOPE control to 0 as you play through the MIDI

MuRF. The effect sounds much choppier - the decay time has been

decreased.

3) Now turn the ENVELOPE control up to 5. The effect now sounds

smooth - the attack is the same time as the decay - like a tremolo effect.

4) Turn the ENVELOPE control to 6. The effect becomes swirly and the

transitions from filter to filter blurred, as the Attack and Decay become so

long that the effect is crossfading from one filter to the next.

5) Finally, turn the ENVELOPE control up to 8. The effect now sounds

"backwards" as the attack time is now smooth but fast, and the decay is

abrupt.

What happens as you change the ENVELOPE control is that the

shape of the Envelopes controlling the gain of the filters morphs. Figure
