“Mark Verbos model 243 Pulser for Buchla systems. Designed off of the core of the Buchla 242. Each step has a pulse in and out so any point can be the beginning or the end of a sequence. Also has a cv in for direct addressing of stages. Very useful and fun module. This is the original version and works perfectly. Mark doesn’t make many of these because they
are very time consuming to assemble. Grab this one now! Works perfectly. Sold as is.” Link

“Verbos designed model 254 Voltage Processor for Buchla systems. Essentially 2 Buchla 257 modules in one , with an additional CV in. Great for smaller systems where in one panel space it can do most of the scaling , adding and modifying of voltages you would ever need. This is the original version. Works perfectly. Sold as is.” Link

“Once upon a time, Don Buchla had a garage sale. Synth geeks familiar with Don and his work AND lucky enough to be on his call list when crazy things like this happen, got a couple of weeks to buy the NOS stock of 200 and 100 series inventory that he had left. I bought a fairly large pile of it for The Audities Foundation collection. This the last oscillator that we have left over from the 200 series systems that we’ve assembled for the Foundation. The parts are NOS from Don or new parts currently manufactured to original spec. It was assembled by the very talented Mark Verbos in New York and function beautifully. Please familiarize yourself with how they operate before you purchase them!! There is a lot of info on the web about all of Don’s instrument designs. ” Link

“In excellent functional and cosmetic condition. Most recent firmware installed.” Link

“This is apparently one of the early 258v’s that Mark Verbos made. There are two flaws with these early models.

- The screen printing is slightly off, so the lines don’t line up with adjacent modules as can be seen in the photo. Not really a problem except for those who are OCD about such things.

- Additionally, it’s a very tight squeeze on some cases due to the screw holes being a tiny bit off. It fitted in my 201-4 rack without any problems, but in my 24 space system, I couldn’t line up the top holes (as can also be seen in the photograph). This may or may not affect other peoples systems, as there seems to be some very slight variation between spacing, and tolerances.
Worst case, you can use it like I have the last year by just screwing it in with 2 screws, and holding it down when removing jacks.

Other than this, it works just fine, and sounds fantastic. It’s amazing for deep boomy bass noises, and the FM sounds that come from it are crazy.
I’m only selling it because I have several similar oscillators in my eurorack system, which I turn to for this kind of sound.
I’d love to keep it, but 200e boat space is at a premium ” Link

“The Model 281e Quad Function Generator has four function generators organized in 2 pairs. All four normally function independently. 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.

The Model 292e Quad Dynamics Manager is functionally identical to the original 292, with the exception of two new features – the 292e has velocity inputs, allowing controllers to control note volumes with performance gestures. And its settings can be stored as a part of a 200e series preset. The 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

“The Model 261e Complex Waveform Generator features voltage-controlled modulation of pitch, amplitude, and timbre, and a multi-dimensional, voltage-controlled timbre space. All of the 261e’s timbre processing is performed by analog circuitry, thus eliminating the aliasing that can be introduced by waveshape table driven systems.

A separate modulation oscillator can be synchronized to the principal oscillator or to note-on MIDI messages. Its waveshape is voltage controllable, and can be continuously varied from sine to pulse. The modulation oscillator can track the pitch of the principal oscillator with variable offset. ” Link

“Buchla Model 206e MIXER/PRESET MANAGER

A six input, two output mixer with controls for level and stereo location. Two of the locations can be voltage controlled; the remaining four can be continuously panned.

A preset manager is also incorporated, primarily for those who want a second preset manager (for a second cabinet), but find a single MIDI interface sufficient” Link

“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!

“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.
