| fourMulator is a digital quad LFO-module for euro rack compatible
modular synthesizer and sound processing systems. Due to its ability to
synchronize the modulators (LFOs) to each other or to an overall
clock-reference, fourMulator is capable generating complex and rhythmic
Each modulator offers six wave forms: ascending and descending saw
tooth, square, triangle, sine and random (sample & hold) with a
frequency range between 0.05Hz (20 seconds) to approx. 100Hz. Each
modulator offers wave form and trigger outputs, the latter sending an
impulse with every new start of the selected wave form. Reset- and
CV-inputs allow external parameter manipulation - from other modules or
from other modulators of the fourMulator itself.
All four modulators work independently. However, they can be
synchronized with each other. Each modulator can be individually
synchronized to the left neighboring module or to a clock-reference.
Two or more synchronized modulators always oscillate at the same
frequency. However, a synchronized modulator can be phase-shifted by up
to 180° (a half-cycle) to the clock-reference. This allows easy
creation of counter-rotating modulations. More complex modulations can
be achieved using the CV-input to manipulate phase-shift.
With active clock-synchronization, the corresponding modulators
oscillate in reference to a common clock-signal, but use individual
clock-dividing factors. Again, advanced possibilities result from being
able to manipulate clock-division through the modules' CV-inputs.
Both forms of synchronization can be combined. With one modulator being
synchronized to a clock signal, it may as well serve as reference to
the right neighboring modulator.
CLOCK Generator (CLK)
fourMulator integrates an internal clock generator. Its tempo can be
assigned using a tap-tempo-button or by using an external
