The OBF from Olitronik is a simple yet useful LFO capable of producing a variety of waveforms with a frequency range of 40 Hz to over 40 seconds per cycle. Using the “Skew” control, Saw, Triangle, Ramp, and PWM are easily attainable, while a pulse set to the OBF’s sync input resets the LFO to -5V, the low point in its cycle.


  • Analog LFO module
  • Rate and Skew control
