buchla/tiptop audio 266t: source of uncertainty price : $299.00

features:
noise source:
pink noise (-3db/oct - low frequency biased)
white noise (flat - equal frequency balanced)
blue noise (+3db/oct - high frequency biased)

fluctuating random voltages:
cv input controls the probable rate of random voltage change
knob osets the probable rate change from slow 0.05hz to 50hz
cv output of voltages with led indicating the fluctuation rate

quantized random voltage: pulse input activates a random stepped voltage at the output
the knob osets 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 aects the "curve" distribution of the right cv output
the knob osets 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 eects)

specifications:
size: 24 hp
depth: 25mm
power: +12v 150ma / -12v 100ma
