Module 266e is the "e" version of the classic "Source of Uncertainty". It is the epitome of extremely musical and extremely differentiated random modulations. Fluctuating Random Voltages are continuously changing, flowing random voltages. Quantized Random Voltages are triggered on time and offer control over the distribution curve and the temporal correlation of the changes. Stored Random Voltages also provide control over distribution and strength of randomness. However, depending on the setting, you can also find classic Sample and Hold. Additionally there is noise in three colors.
The noise section offers noise in three variants: Normal, high pass and low pass filtered.
Fluctuating Random Voltages offers two continuously changing random voltages. The speed at which these voltages change can be controlled manually and via CV.
Quantized Random Voltages offers two quantized random voltages that are independent, but share one parameter set. The module must be triggered with a pulse. Number of states defines how many different quantized voltages occur. The number ranges from 2 to 24 and is voltage controllable. Distribution determines whether all voltages, whether low, medium or high, occur evenly or whether mean CV values are more likely. Time Correlation determines how fast the random values move away from each other.
Stored Random Voltages offer two random voltages with a split parameter set. They behave similar to Quantized Random Voltages and must also be triggered. The parameter "Degree" determines the depth of the random modulation. Chaos determines the distribution curve from narrowband to wide. Skew can be used to set whether low or high stresses are preferred as the starting point. All parameters are voltage controllable. If all controls are in their zero position, you can realize classic S/H with a signal patched into the Skew CV input and add random changes to this voltage with degree and chaos.
In combination with the Preset Manager of the modules 206e and 225e all parameters can be stored and recalled.
Pioneering synthesizer design since the mid 1960s with Morton Subotnick and the San Francisco Tape Center, Don Buchla has been responsible for the invention of the sequencer, low pass gate, random voltage generators and the complex oscillator, among others. Shortly before his passing in 2016, his rights were acquired by Australian holding company BEMI (2012-2017) and since 2018 is operated by Eric Fox of Buchla USA, based in Minnesota. Buchla USA offers the whole 200e series catalog and boats, as well as the iconic Music Easel.
