MAKE THIS CONNECTION
Patch another one of the MULT outputs to a new ATTENUATOR input. Now, patch
the output of this new ATTENUATOR to the CUTOFF 2 IN. Make sure that this second
attenuator's knob is turned fully counter-clockwise.
The first attenuator acts as an attenuator for both left and right motion, since the
attenuated version then goes down to the second attenuator which completely inverts
whatever signal is coming in. If you move the second attenuator knob completely
clockwise, we return to mono with both filters moving in sync. Moving the second
attenuator knob back to fully counter-clockwise returns us to stereo space with the
filters moving in opposition directions.
With this patch, we've taken a pretty typical subtractive synth effect—an LFO moving
the filter up and down—and created a much deeper stereo version using just a
handful of patch cables and a few utility modules. While utilities like mults and
attenuators don't exactly stand out as being the most exciting parts of a modular
synthesizer, this exercise shows just how important they can be in creating more
interesting and exciting patches.
