Buchla & Tiptop Audio - Series 200

TipTop Audio, in cooperation with Buchla, has realized a completely Eurorack compatible version of the complex random voltage generator model 266. The Source or Uncertainty 266t offers a wide range of random control voltages, some of which are more rarely found in the Eurorack area. A total of six function groups are available, which could not be more different.

Noise Source is a noise generator that provides white, pink and blue noise in parallel.

The two Fluctuating Random Voltages generate unpredictable, smoothed voltages that do not repeat and are adjustable in speed.

For the Quantized Random Voltages the outputs n+1 and 2n are available. Here N is a number in the range 1-6, which is adjusted with the controller N and additionally an external control voltage. Each time the rising edge of the incoming pulse signal is detected, a new random voltage is generated at each of the two outputs, which can assume a maximum of N+1 respectively 2N states. For example, if a value of 4 is set, a maximum of 5 different random states are possible at output N+1, and 16 different random states are possible at output 2N.

For the Stored Random Voltages there are also 2 outputs available: one output with uniform distribution of the possible 256 states and one output with adjustable distribution of the amplitude frequency. The distribution is adjusted manually with the controller and additionally with an external control voltage. At the left output with uniform distribution all states are equally likely. At the lower output, lower, medium or higher voltage levels appear more frequently. The symbol at the right output socket represents this situation graphically.

Sample & Hold does exactly what you would expect: Wait for gate, Clock or trigger at the input, sample the voltage at CV-In and output the voltage value held at the trigger time at CV-Out. The two Pulse-Alt outputs will output the first respectively second pulse of the incoming pulse signals. A/B FlipFlop could also be called this. The Alt-CV outputs provide a variation of the output CV including the amplitude start and end of each pulse.
The integrator is actually a slew limiter whose "bend parameter" is voltage controlled. The slew limiter turns a square wave into a trapezoid and smooths stepped control voltages like eg. Pitch CV or the output of a S&H.
