“Re-listed with BIN, due to non-paying bidder.

I’m also opened for trade with old synthesizers, modules…

Extremly rare BUCHLA electric music box series 500 modules. ….only 3 exemplars ever made in the world!!! The cv interface module need of PSU and computer facilities … I’m convinced that the joysticks and trigger, control voltages module can drive other modular systems with a right psu of course, they have a Cinch Jones plug for Power Supply and a pair of facilities connectors in the rear part. I don’t know the right voltage that they need, I haven’t any schematis.. I bought them for collection but ..I think they need of a new home with other Buchla brothers Amazing: the two joysticks are photosensitive built with optoisolators ..so the sticks are luminescent…a primitive but charming devices! Shipping and packing costs to Europe are of 34 euro about. Spedizione e imballaggio in Italia: 14 euro ” Link

“If you are reading this auction, you know what this module is. The Buchla Model 266e Source of Uncertainty provides a noise source, random voltages, and can be configured to provide pure sample and hold. There are four sections to this module: noise source, smooth fluctuating voltages, quantized random voltages and store random voltages with voltage control of probability (really cool feature once you figure it out and this is how you can achieve pur sample and hold). The module is in excellent condition and is both physicially and electronically sound. The firmware memory card is included with this auction.. Other features include:

* Noise comes in three flavors. White noise is electrically flat, but acoustically balanced toward the high end of the spectrum (+3 db/octave). Integrated white noise has a low spectral bias (-3 db/octave). Musically flat noise has a flat spectrum (constant energy per octave) and is a particularly useful source for subsequent processing.
* Fluctuating Random Voltages are continuously variable, with voltage control of bandwidth over the range of .05 to 50 Hz, making possible changes that vary from barely perceptible movement to rapid fluctuation.
* Quantized Random Voltages change on receipt of pulses. Their number of states is voltage controllable from two to twenty-four, and their distribution can be varied both spatially and temporally.
* Stored Random Voltages have three parameters under voltage control. Degree varies the amount of randomness; chaos alters the distribution from just a little uncertain to total chaos; while skew biases the randomness toward one extreme or the other.
* All settings of the 266 may be stored and recalled under control of the model 225e or 206e preset manager.” Link

“If you are reading this auction, you know what this module is. The Mark Verbos Model 258v Dual Oscillator is designed to duplicate the sound and response of the highly regarded Buchla 258 and does so. The 258v is fully compatible with Buchla 200 and 200e systems. It connects to the same power supply, outputs the same signal levels, and responds to the same voltage control. You have never heard gurgling, burping, watery, klanging FM like that produced with the 258v. This module features two seperate VCO’s, continuously tunable from 5 Hz to 20 kHz. Each VCO has two processing inputs and a frequency modulation input.l Waveshapes as well as frequency can be voltage controlled. Model 258v oscillators feature low sine wave harmonic content. There is no memory card with this module, it is fully analog and cannot store presets. Other features include:

* Processing inputs: Two processing control inputs permit multiple control of pitch without need of separate external processor.
* Processing controls: Used to set desired range of frequency control. Expansion, compression, and inversion of scales are accomplished here.
* Frequency modulation control: For adjusting vibrato depth or creating clangorous or bell-like tones, rich in non-harmonic partials.
* Output: Signal amplitude is +4 dB. Output impedance is 600 ohms.
* Oscillator frequency control: Spans the audio spectrum of 5 Hz to 20 kHz with no range switching. ( Applied control voltages can extend limits to .1 Hz and 30 kHz.) (this means that the modules also function as VCLFO’s).
* Waveshape control input: Waveshapes can be varied from sine to saw (osc 1) and sine to square (osc 2). Voltage control of waveshape enables powerful dynamic control of timbre.” Link

“If you are reading this auction, you know what about Buchla modules. The Buchla Model 292e Quad Dynamics Manager is four lowpass gates with individual outputs and one summed output. The 292e respondes to voltage control, A/D or ADSR envelopes, and even aftertouch via the 225e midi interface. The module is in excellent shape and is both physically and electronically sound. Included is the firmware memory card. Other features include:

* 292e sports four independent voltage controlled amplifiers. Each has a signal input and output, a control voltage input that varies the unit’s gain from -120 to +3db, an offset adjustment, and a velocity input. The latter adds further control to the gain when employed and becomes transparent when unconnected.
* A switch selects one of three operating modes: straight gate (VCA), lowpass filter (VCF), or a combination of the two, in which the spectral response varies as the gain is changed.
* Frequency domain gating imparts a dynamic tonal variation that gives the listener a sense of absolute loudness. This quality is characteristic of all acoustic instruments (the harder you strike, pluck, or blow, the richer the overtone structure).
* A mix of the four output signals is also provided. Aided by the model 225e or the 206e preset manager, the settings of the 292e can be stored and retrieved.” Link

“If you are reading this auction, you know what this module is. The Buchla Model 281e Quad Function Generator is four seperate Attack/Decay envelopes. The duration of both Attack and Decay can be modified by control voltage. Sections 1 & 2, and section 3 & 4 can be placed in quadrature mode to create the familiar ADSR envelope. The module is in excellent shape and is both physically and electronically sound. Included is the firmware memory card. Other features include:

* A momentary switch selects one of three modes: transient, sustained, and cyclic. An illuminated LED indicates the selected mode.
* On receipt of a pulse, the output voltage ramps up to 10 volts at a rate determined by the sum of an applied control voltage and the setting of the attack time knob. If in the sustained mode, the voltage will stay high as long as the input pulse is maintained. If not in the sustained mode, or when the input pulse terminates, the output ramps down to zero at a rate determined by the sum of the decay voltage and the setting of the decay knob.
* At the end of the decay, a transient pulse appears at the pulse output. If in the cyclic mode, the cycle now repeats.
* The time range for both attack and decay is from .001 to 10 seconds.
* In the quadrature mode, generators A and B (or C and D) operate in tandem to provide functions shifted by ninety degrees. The mode is selected with a switch and indicated with LEDs. An OR function can be invoked to generate more complex envelopes (ADSR).
* The model 225e or the 206e preset manager can issue commands to store and recall the 281e’s settings.
* The 281e can respond directly to MIDI signals received by the model 225e MIDI interface.” Link
