Module 267e combines noise in three colors, two random voltages and two voltage-controlled bandpass filters in a single module. Perfect for providing a high degree of flexibility in functions and timbres, even in smaller systems.
The noise section offers noise in three variants: Normal, high pass and low pass filtered.
Two identical random sections offer Fluctuating Random Voltages, which are voltage controllable in the rate of their change. This random voltage can be added to an external control voltage to make it more "random". A trigger input allows the signal to be sampled at any time and then applied to the separate S&H output.
Two identically constructed bandpass filters can be voltage controlled in frequency and bandwidth. The "Mod In" input allows amplitude, frequency and/or bandwidth to be modulated in any combination for an audio signal. The modulation depth can be adjusted manually or via CV. The unfiltered noise from the noise section is normalized to both inputs of the filters. If the input is used with a different signal, this connection is interrupted.
In combination with the Preset Manager of the 206e and 225e modules, 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.
