Its great sound and jaw-dropping effects come from the state-of-the-art analog circuitry, designed and built under Bob Moog's personal direction. Your MuRF is a direct descendent of the original MoogTM modular synthesizers and professional rack effects. [. . . ] The EP-1 can now slow down or speed up the LFO. ENVELOPE GENERATORS Now that we have explained the MuRF's filters, let's proceed with some more definitions to explain the Animation function of the MuRF. In many vintage or analog sequencers, a sequencer typically had eight or sixteen steps available to build a pattern. In its simplest form, as a sequencer plays back its steps, each step can be programmed to send a trigger signal - or not - a step can be passed over like a musical rest. 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 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 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 pre-programmed 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 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 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 MuRF.

MF-105 SPECIFICATIONS DESCRIPTION: Analog effects module incorporating two functions: 8 ­ band Resonant Filter Bank and 24-Pattern Sequencer triggering Volume Envelopes for 8 Filters. FRONT PANEL FEATURES: DRIVE rotary control - adjusts the gain of the audio input to the effect. OUTPUT rotary control - balances the level of MuRF's signal when the effect is on with the bypassed signal when the effect is off. [. . . ]
