Befaco Sampling Modulator

8-step trigger sequencer meets sample and hold VCO

8 HP Eurorack module

The Sampling Modulator is a Eurorack module combining a V/Oct pulse VCO (internal clock), an 8-step trigger sequencer, and a sample-and-hold circuit into a single unified voice. It can be clocked internally or externally, making it ideal for generating melodic random voltages, rhythmic CV sequences, and experimentally gated sample-and-hold textures with tight sequencer integration.

Features

  • Internal V/Oct pulse VCO usable as clock source
  • V/Oct CV input for pitch-accurate VCO control
  • V/Oct trimmer for calibration of 1V/octave tracking
  • RATE and RATE FINE knobs for internal clock speed control
  • 8-step trigger sequencer with individual step enable/disable toggles
  • 8 individual step LEDs (D2-D9) showing active steps
  • Internal/External clock selection via two-position toggle switch
  • Clock Out jack for sending internal clock to other modules
  • Clock/Sync In jack for external clock input
  • Sample and Hold circuit with dedicated IN and HOLD inputs
  • Trigger Out jack for sequencer trigger output
  • Signal Out jack for sample and hold output voltage
