Vermona fourMulator Quad LFO

Vermona fourMulator - Quad modulation and trigger engine

Do you really need four LFO units in a single module? You cannot really have enough LFOs, can you? Even a classic synthesizer easily offers four targets for LFO modulations. To name a few: vibrato, pulse width, the filter’s cutoff frequency and tremolo. In a modular synthesizer there are even significantly more options. Now add the options deriving from a combination of multiple LFOs to create interaction between the units to make these applications more thrilling.

Vermon's fourMulator is a Quad-LFO with rich feature-set. Its four sync-able, phase-variable and CVcontrollable LFOs are able to create trigger-sequences that can be varied in real time thanks to a comfortable user interface. fourMulator acts as a modulation as well as clock-central and is capable of being your new clockreference for your modular synthesizer.

The modulators
Every LFO offers a choice of six wave forms: ascending or descending saw tooth, square, triangle, sine and a random curve (Sample & Hold). These oscillate in frequencies between 0.05Hz (20 seconds) and approximately 100Hz – fast enough for sonic alienation of oscillators, filters and VCAs. Each modulator offers individual wave-form- and trigger-outputs. The latter output a trigger impulse with every restart of the wave form. In addition, individual reset- and CV-inputs allow adding further manipulations from externally or within fourMulator.

Synchronization

• The four modulator sections work independently generally, but may be synchronized to a clock-signal.
• Two or more synchronized modulators oscillate at the same frequency, but not necessarily at identical phase. A synced modulator may be shifted by up to 180° – a half-cycle - to its neighbor. This way, you may easily create counter-rotating modulations. And by using the CV-inputs for phase modulation, even more complex structures become possible.
• When being synchronized to a clock, the modulators oscillate with defined but adjustable clock divisions to the reference. Here too, being able to modulate the dividers by a control-voltage, highest-level versatility is guaranteed.
• Both sync-modes can finally be combined. This way, you may synchronize one modulator to a reference clock, while it simultaneously serves as a master for its right neighbor.
