Buchla 266t

SOURCE OF UNCERTAINTY – MODEL 266t

Fluctuating Random Voltages:
– CV Input controls the probable rate of random voltage change
– Knob offsets the probable rate change from slow 0.05hz to 50hz
– CV Output of voltages with LED indicating the fluctuation rate

Noise Source:
– Pink noise (-3db/oct – low frequency biased)
– White noise (flat – equal frequency balanced)
– Blue noise (+3db/oct – high frequency biased)

Quantized Random Voltage:
– Pulse Input activates a random stepped
voltage at the Output
– The knob offsets the varying number of steps
from setting 1 to setting 6
– CV Input controls the number of steps
– n+1 is more locally scaled in the 5V range
– 2^n is more equally distributed over a 10V
range

Stored Random Voltage:
– Pulse Input activates a random stepped
voltage at the CV Outputs
– The left CV Output is an evenly distributed
random voltage
– The right CV Output has a potentiometer and
CV input to determine the random voltage
distribution.
– CV In affects the “curve” distribution of the
right CV Output
– The knob offsets the “curve” distribution of the
right CV Output.
Fully counterclockwise skews in favor of lower
voltages. The middle is a bell curve distribution
and clockwise skews toward higher voltages.

Integrator:
– Input is looking for discrete or stepped voltages
– The knob proportionally smooths out the incoming voltage from 0.01
(no smoothing) to 10 (dramatic smoothing, glissandi)
– CV Input controls the smoothing potentiometer
– TR1 is a trimmer on the back of the module, it adjust the range of the Integrator.

Sample and Hold:
– Pulse Input samples the voltage at the CV Input
– Pulse “alt” divides the incoming pulse into alternating pulse outputs
– CV Input for periodic, continuous or fluctuating voltages
– CV Output of the complete voltages
– CV Output “alt” divides the voltages into alternating outputs (great for ping pong effects)
