227e is a combination of three functional blocks: master mixer, microphone preamplifier, sub-mixer. The master mixer has four independent inputs with individual gain adjustment. The "spatial dynamics" function determines the position of the source in a...
230e is the reincarnation of the classic Buchla 230. The modern module has an expanded functionality: now it can be used not only as an envelope generator, but also as a preamplifier, or even a three-channel mixer. Three built-in preamps have inputs via...
250e module is a 16-step sequencer. Each step contains two parameters controlled by potentiometers. The parameters of each step can be interpolated, quantized, or replaced by external CV signals. The current step is indicated by the corresponding...
Buchla 251e is represented with four 50-step sequencers. Each of them has independent outputs (pulse and CV) and control inputs (start/stop). The parameters of each sequencer are programmed in series through the SEQ edit and STAGE edit. All the...
252e is an original generator of patterns. The front panel is mostly represented with a round display, it shows the parts of the rhythmic sequences in the form of eleven rings with the number of steps from 3 to 16. Each channel has its own color. The...
Buchla 256e is represented with 4 identical functional blocks designed for: scaling, inverting, combining, multiplication of control voltages (CV). Each unit has two inputs, the mixing of signals is regulated by one knob. There is also an "in select"...
At the top of 257e there are two CV processors. Functionally they are the same as in 256e with the only difference that they have one input and, accordingly, there is no CV mixer. It is possible to set the minimum and maximum value of the control signal,...
Buchla 259e is a system of two oscillators: a complex waveform generator and a modulation generator. The Principal Oscillator can produce signals within nine octaves. Two wavetables are used to construct the signals. Voices can be selected from banks:...
261e module generates sound by interaction of the two generators (principal and modulation). Principal oscillator generates a sine wave within the range from 27.5 to 7040 Hz. The base wave can be transformed into a more complex one with the help of a...
Four functional units are combined into one enclosure to create a musical unpredictability or arrange a “source of uncertainty”. There’s a noise generator at the top of the module. It has three outputs: 3 dB / oct - white noise; -3 dB / oct - white noise...
