  • Page 1 User Guide...
  • Page 2 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 clock- reference for your modular synthesizer.
  • Page 3: Getting Started

    To ensure op quality we carefully checked the module before packaging. Nevertheless, we cannot fully exclude damage during transportation. Therefore, we kindly ask you to inspect the fourMulator by yourself, once you receive the module. In case there is anything unusual about the unit or its packaging, do not hesitate to contact us, so we can take care of the problem.
  • Page 4 Setup The fourMulator was designed to work in modular synthesizer systems using the common eurorack format. Its power supply, connectors and dimensions match the typical specifications (VERMONA Modular Case, Doepfer A-100 and compatible systems). Installation is carried out just like for any module:...
  • Page 5 Mount the fourMulator to your modular frame using the supplied screws. To protect the unit's surface from scratches, use the supplied flat plastic washers. Reconnect the power cable to your frame and switch on the power-supply. The fourMulator is now ready to operate.
  • Page 6 - overview and functions Simply described, the fourMulator is a quadruple LFO, with all LFO units (herein after referred to as Modulators) being able to run freely or synchronized to each other. All four Modulators are equipped equally with one exception: Modulator q can only act as sync reference to the other three Modulators, while these may act as sync reference or being synced to their left counterparts.

  • Page 8 0.05 Hz to 100 Hz. Therefore, modulations with audible frequencies are only possible within limits. The fourMulator’s focus within the sub audio range is intended because higher frequencies would not make sense for use of the unit as clock-/ trigger-generator or for reciprocal modulations.
  • Page 9 The tempo is displayed using the corresponding LEDs for every SPEED control w. With every commencing new wave-form-cycle, the LED will be lit. For Modulators being synchronized and being shifted in phase, the LEDs flash with the same tempo but with a corresponding delay. User Guide fourMulator...
  • Page 10 SYNC switch e The SYNC switch offers three positions: OFF, SYNC and CLK. Modulator q only offers OFF and CLK positions since it can only be used as a sync reference but cannot be synchronized itself. OFF: The Modulator runs at the speed set with the corresponding SPEED control.

  • Page 12 The Modulators Connections Each Modulator offers four jacks to be connected to other modules. WAVE r This jack outputs the selected waveform. Connect this output to a CV-input of any module. Typical applications would be modulations of a filter’s cutoff frequency, an oscillator’s pulse width or an oscillator’s pitch. TRIGGER t This jack outputs a trigger signal with the start of each new wave form cycle, allowing to trigger modules such as envelopes, electronic switches or sequencers.
  • Page 13 TAP button i Use this button to set the tempo for fourMulator’s internal clock. A tempo change will occur after tapping the button four times. For predictable results, tap in a constant rhythm.
  • Page 14 Further connections Trigger-sequence output (TRIG SEQ) s The trigger-sequence being available on this output is a deduction of the trigger-signals of all synchronized Modulators. At least one of the Modulators w, e or r needs to be synchronized for the trigger-sequence to be active.
