Buchla 266-based source of multiple types of uncertainty.

SPUTNIK WEST COAST RANDOM SOURCE does exactly what its name suggests and is a random source of unpredictability, packed with functionality. West Coast Random Source features:

Fluctuating Random Voltages

Two sections for creating a fluctuating voltage
CV input and control over a bandwidth of .05hz to 50khz

Quantized Random Voltages

Pulse input for generating 1v/oct quantized random voltage
CV input and knob for controlling distribution of random voltages
Two different algorithmic outputs:
“N+1 states” and “2N states“. N is an integer number in the range 1…6 that can be adjusted with the manual control (Man N) and an external control voltage CVN with attenuator. Whenever the rising edge of the input clock signal (Clk In) appears a new random voltage is generated at the N+1 resp. 2N output. The N+1 output is capable to generate N+1 different voltage levels (or states), the 2N output up to 2Ndifferent states. If for example N is set to 4 the N+1 output generates up to 5, the 2N output 16 different states. The voltage steps of the 2N output are adjusted to 1/12 V in the factory.

Stored Random Voltages

Pulse input generates random voltage
1st output covers 0-5V range
2nd output is voltage controlled and knob alters the distribution of voltages

Noise Source

Three dedicated outputs for pink, white and blue noise

Sample & Hold

CV input, pulse input and CV output
odd/even pulse output (for deciding incoming pulses)
odd/even cv output (for sampled voltages)


Portamento/slew/glide with voltage control over slew time
