and the transitions from lter to lter blurred, as the Attack and
Decay become so long that the effect is crossfading from one lter
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.
What happens as you change the ENVELOPE control is that the
shape of the Envelopes controlling the gain of the lters 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
decrease and slower Rate
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. Tapping three times activates the tap tempo
feature of the MuRF. 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. Note that the Rate light becomes green when
the rate is set by the Tap input, and returns to red if the RATE
control is changed. The tempo of the Animation is twice the rate
that is tapped on the footswitch. In other words, if you tap in
quarter notes, the Animation will chug along in eighth notes. If you
tap eighth notes, the Animation will proceed in 16th notes.
