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
