You 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 MuRF - keep in mind that lter effects work by removing
frequencies, so you must have a bright sound to hear the effect!
Figure 6 shows the MF-105’s basic frequency response, the
response that you hear when the panel controls are set up as in the
basic setup. Note that there are 8 resonances – they impart warmth
and color to the sound. For a moment press the bypass switch and
turn the effect off. Note the change in character of the sound. Now
switch the effect back on.
6) Now turn all the sliders down except the lowest one. Figure 7
shows the frequency response of just the lowest lter. Experiment
by turning each slider up one at a time, while the rest of the sliders
are all the way down. Pay careful attention to the sound of each
lter. When you have learned the sound of each individual lter,
try various combinations, such as the bottom two and top two.

Note that even without
Animation, the MuRF is
a VERY POWERFUL
lter bank with many
possibilities to sculpt your
tone!
