Vermona fourMulator

Four digital LFOs with sync, phase shift, and a built-in clock

34 HP Eurorack module

The Vermona fourMulator is a digital quad-LFO module that goes well beyond simple cyclic modulation. Each of its four Modulators offers six waveforms across a 0.05 Hz to 100 Hz range, with individual wave and trigger outputs plus CV and reset inputs. Modulators can free-run, sync to their left neighbor with adjustable phase, or lock to the built-in tap-tempo clock at one of eight divisions, making it both a modulation powerhouse and a clock/trigger hub for the rack.

Features

  • Four independent digital LFOs (Modulators) in a single 34HP module
  • Six waveforms per channel: ascending/descending saw, square, triangle, sine, random (S&H)
  • Wide frequency range from 0.05 Hz (20 s) up to ~100 Hz audio rate
  • Per-channel Wave (bipolar -5/+5 V) and Trigger (+12 V) outputs
  • Per-channel CV input for frequency / phase / clock-division modulation
  • Per-channel Reset input to restart the waveform on a gate
  • Sync switch per channel: OFF (free), SYNC (to left neighbor), CLK (to clock)
  • Phase shift of 0-180 degrees between synced neighbors for counter-rotating motion
  • Eight clock divisions (1/1 to 1/32, with triplets) when CLK-synced
  • Built-in clock generator with tap-tempo (four taps to set)
  • CLK Out shares the internal clock; CLK In accepts external clock of any resolution
  • TRIG SEQ output combines all synced channels' triggers into one rhythm
