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
