5) Now, play a bright, sustained sound, preferably of low pitch into
the MIDI MuRF - keep in mind that filter effects work by removing
frequencies, so you must have a bright sound to hear the effect! Figure 6
shows the MF-105M's MIDS 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. While playing
your instrument, turn 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
filter. When you have learned the sound of each individual filter, try
various combinations, such as the bottom two and top two. At this point
you will want to repeat steps 5 and 6 with the FREQ slide switch moved
to the BASS voicing position. Figure 7 shows the frequency response of
the 8 filters in the BASS voicing setting. This will familiarize you with
the sounds of the two voicings. Note that even without Animation, the
MIDI MuRF is a VERY POWERFUL filter bank with many possibilities
to sculpt your tone!
can hear the effect of just the filters.
3) Make sure the effect is on, and MIX is at
10.
4) Connect just the "left/mono" output
to your amplification. You may want
to experiment with the panel controls
and switches as we discuss each of the
parameters.
