Vermona fourMulator - quad modulation engine - Manual (Page 15)

Using the fourMulator
fourMulator can act as a control- and clock-central. However, this only
makes sense in combination with other modules. The following sections
offer a few helpful suggestions for using the fourMulator.
Reciprocal modulations
LFOs run statically. This might be desirable for some applications, while
for others this behavior appears lifeless. Because of their ability to be
CV-controlled, the LFOs in the fourMulator can act more organic. To do
so, create a modulation between two modulators and vice versa, the so
called cross-modulation.
Use multiples to duplicate the wave outputs of both modulators. This is
necessary because you will need to address the modulation target (filter
frequency, pitch) as well as the other modulator. A multiple with two or
three separated sections is recommend (Doepfer A-180, Intellijel
Buffered Multiple, WMD Buffered Multiple).
Patch one output into an attenuator (dedicated modules: Doepfer
A-183-1, Intellijel TriAtt, Malekko 8NU8R or use simple VCAs/mixers).
The attenuators are necessary, to adjust the amount of cross-modula-
tion. Now, patch the attenuator's output to the CV-input of the other
modulator:
WAVE 1 > Multiples 1 > Attenuator 1 > CV IN 2
WAVE 2 > Multiples 2 > Attenuator 2 > CV IN 1
Add another patch chord per modulator to connect the multiple-output
to the modulation target. The resulting modulation is more complex
than a common CV-controlled speed modulation that also runs
periodically.
Essential for this setup is the right amount of modulation depths and
the modulators' speed settings. (Note that the modulators must not be
synchronized). Start experimenting by using a triangle wave form. How-
ever, other wave forms also lead to interesting results.
The same setup can also be used, with either modulators or at least
modulator 2 being switched to CLK. Here, not the frequency but the
clock division (siehe "(3) SYNC-switch", Seite 11) is modulated. The
resulting modulation is not as complex but it will grant you with pre-
dictable rhythmic patterns instead.
