sound. Some types of filters (like the bass and treble controls on your sound system) have subtle, gentle effects on a sound’s timbre. Other types of filters have stronger and more dramatic effects, and are frequently used as vital elements in the music-making process. Strong filters include phasers...

3) Make sure the effect is on, and MIX is at 10. 4) Connect just the “left/mono” output to your amplificationYou may want to experiment with the panel controls and switches as we discuss each of the parameters.5) Now, play a bright, sustained sound, preferably of low pitch into the Bass MuRF. Figure...

done two ways, depending on the position of the BANK slider switch. The switch, located below the PATTERN selector switch is labeled BANK A or B/LFO. When the slider is in the “A” position, the filters’ center frequencies can be shifted by an expression pedal (such as the Moog EP-1) or CV plugged in...

ENVELOPE GENERATORS Now that we have explained the Bass MuRF’s filters, let’s proceed with some more definitions to explain the Animation function of the Bass MuRF. The term “Envelope” is used to describe the changes that occur to a musical sound, from its start to its end. A musical sound can have ...

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. W...

THE AUDIO LEVEL CONTROLS AND MIXING The DRIVE control adjusts the signal level at the Bass MuRF’s circuit input. With this control you can set the right input level for virtually any instrument or line-level signal source. Turn this control counterclockwise for strong input signals, and clockwise fo...
