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
