Uncertainty, randomness, noise...
Tiptop Audio and Buchla team up to bring you the Model 266t Source of Uncertainty. Inspired and designed after the legendary synths and instruments by pioneer, Don Buchla; the 266t will beckon back to early days of sound synthesis and bring to the modern day a key building block element to eurorack modular systems, random voltage creation and manipulation.
Noise is at the heart of the 266t
Three different noise types (pink, white, and blue) are available to create random CV voltages, as unpredictable as a noise signal can be with its varying harmonics. Though noise is also a useful tool for crafting percussion sounds when you send the audio output of the noise to a pinging filter and short envelope (add effects and CV manipulation for flavor to your heart's desire).
Noise Source:
- Pink noise (-3db/oct - low frequency biased)
- White noise (flat - equal frequency balanced)
- Blue noise (+3db/oct - high frequency biased)
The 266t doesn't only make noise though, it contains several useful tools any patch will benefit from. Sample and Hold, Quantized Random Voltage generating, Stored Random Voltages input and output, offsets, and more!
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
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
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
