[. . . ] The trigger signals can then be used to trigger envelope generators according to the way each step is programmed - creating a rhythmically reoccurring pattern. The Bass MuRF's Animation contains 8 simple sequencers, one for each filter, each capable of triggering an Envelope Generator that shapes the volume of the filter. ANIMATION The Bass MuRF's ANIMATION module is designed as a means of automatically turning the levels of the individual filters up and down, using envelope generators, according to a preprogrammed pattern. The ENVELOPE control morphs through different envelope shapes as you turn it, creating effects that are highly rhythmic in nature, or are swirling and ethereal. The RATE control sets the speed of the pattern. The patterns, selected by the PATTERN selector rotary switch in conjunction with the Bank slider switch, have been selected to provide a surprisingly wide variety of rhythmic timbral effects. There are a total of 24 patterns, arranged in two banks of 12. An easy way to understand the Animation is to look at a simple pattern displayed on a grid. Figure 10 shows a graphic representation of pattern 2 in Bank A. The columns going left to right Figure 10 - Diagram of Pattern 2, Bank A are the steps of the pattern. The rows going from bottom to top are the individual filters. Illustrations of all the Patterns are in Appendix A, page 22. Return to the basic setting shown in figure 2, which features pattern 2. As you play your instrument through the Bass 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 Bass 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 Bass MuRF. The effect sounds much more choppy - 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. [. . . ] ENVELOPE rotary control - morphs the shape of the patterns' envelopes. RATE rotary control - adjusts the rate of the animation patterns DRIVE, a three-color LED that shows the level of the input signal. RATE, a LED that indicates the animation pattern rate. BYPASS, a two-color indicator LED that tells whether the effect is active or bypassed. [. . . ]
