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 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 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. An easy way to understand the Animation is to look at a simple pattern displayed on a grid. The columns going left to right Figure 10 - Diagram of Pattern 2, Bank A are the steps of the pattern. 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. The effect sounds much more choppy - the decay time has been decreased. The effect now sounds smooth - the attack is the same time as the decay - like a tremolo effect. 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. 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 11 shows the changes to the envelope times at different settings of the Envelope control. The Envelope times also change as the Rate changes - faster Rate settings cause the envelope times to Figure 11 - Effect of the ENVELOPE control decrease and slower Rate on the MuRF's attack and decay times settings slow the envelope times. This makes the MuRF capable of both rhythmic and smooth-changing, swirling effects. Spend some time to get to know how this control interacts with the different patterns and you will be rewarded with some very interesting sounds!THE MuRF'S TAP/STEP INPUT The MuRF's Animation can be synced to the tempo of the music using a Moog FS-1 footswitch or equivalent plugged into the TAP/STEP input. The MF-105 calculates the time in between taps and translates this into the rate for the pattern. It is important to make the time between the taps as much the same as possible to get the best results. [. . . ] Wrap your MF-105 carefully and pack it with the power adaptor in its original carton. The warranty will not be honored if the product is not properly packed. Then send it to Moog Music with transportation and insurance charges paid. A reasonable cost for service and for materials and return freight will be charged to replace materials defective through the fault of the user, or for which the one year warranty period has expired.
