Vermona modular fourMulator


The fourMulator is a quad digital, voltage controllable LFO with Tap-Tempo and LFO synchronisation to an external clock. Synchronisation to an adjacent LFO is possible as well and gives you the possibility to shift the LFO´s phase.



The fourMulator contains four (digital) LFOs with following waveforms: rising and falling sawtooth, square, triangle, sine and random (SandH) and it works beyond this as a clock generator with tap-tempo function.

Each LFO can be free-running, synchronized to the master clock or synchronized to the preceding LFO. When synched to the clock the LFO can oscillate in a fraction or multiplicator of the clock. When synched to the preceding LFO you can shift it´s phase (and the start of the wave form) continuously up to 180°.

Each LFO (called "modulator" in fourmulator language) has a reset input and CV input that always affects the function of the Speed/Phase control, either frequency, clock divisor, clock multiplier or phase. Each modulator hase a wave form output and a trigger output that fires a trigger at each start of a waveform. Furthermode you´ll find a master reset input affecting all modulators that don´t use the individual reset input.

The Trigger Sequence output carries the sum of all synchronised trigger impulses. By shifting the modulators´ phases you can generate rhythmical structures.
