Sampling Modulator

Befaco

Multi-function module that lies somewhere between a VCO, a Sample & Hold, and an 8 step trigger sequencer. Can function as a sequencer clocked sample & hold, analog down-sampling effect, sampling modulator/shaper, 8 step trigger sequencer, and unusual V/Oct VCO. Uses a temperature compensated ramp core VCO with more than 4 octaves of tracking.197

Capabilities 4

Clock Dividerclock-divider
197
Sample and Holdsample-and-hold
Sequencer-clocked S&H capable of producing more interesting patterns than a standard S&H. HOLD input keeps a sample frozen while the module continues to track the waveform internally.197
Step Sequencerstep-sequencer
8-step trigger sequencer with switches per step (On/Off/Reset). Useful as a clock divider. Trigger outputs can also serve as a pulse VCO.197
Voltage-Controlled Oscillatorvco
Temperature compensated ramp core VCO with more than 4 octaves of V/Oct tracking. Internal clock runs up to 25kHz without external CV and up to 200kHz with CV. Can be used as a pulse VCO via trigger outputs.197

Jacks 6 — 4 in / 2 out

NameSignalVoltageDescription
Inputs (4)
CLOCKclockCan be used to set the rate of the internal VCO and sequencer. Can work as a typical clock or in positive going hard sync mode.197
HOLDgateA gate on this input will hold the current sample/waveform position. The module continues to track the waveform and returns to it once the gate is removed.197
INaudioAudio input routed to the internal Sample and Hold.197
V/Oct CVcvVolt/Oct CV input to the internal VCO. Has 4 octaves of tracking.197
Outputs (2)
CLK OUTclockClock output from the internal VCO.197
TRIG OUTtriggerTrigger output from the internal 8-step sequencer. Can also be used as a pulse VCO output.197

Parameters 4

NameTypeRangeBehavior
FINEknobFine rate control for the internal VCO.197
INT/EXT Clock SwitchswitchSelects between the internal VCO clock and an external clock input.197
RATEknobCoarse rate control for the internal VCO. The internal VCO runs up to 25kHz without external CV.197
Step Switchesswitch8 switches, one per step. Up=On, Middle=Off, Down=Reset (resets to first step for non-4/4 signatures). Flipping switches on and off changes timbre when used as a VCO or sampling modulator.197
