Buchla Model Model 281e AND Model 292e

via this auction
http://buchla.com/
"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."

Pan Kat Synth Steel Drum

via this auction

"Synthesized Steel Drum / Steel Pan... It also has other patches and more than 50 other instruments, but the main deal is the steel pan; it's laid out like an actual steel drum, and the sounds are better than any synth pan I've ever heard. From one side to the other it is 30 inches. Only used twice in the studio.

The PanKat comes with the manual, the stand, power adapter, mallets, and will be shipped in a lined, padded steelpan case. This thing is perfect for recording... no need to "touch up" or find a tuner to play it anytime.

RETAIL on this item was $2100; we purchased it for $1800."

Early ARP Synthesizer Factory Service Manuals

via this auction

"I was an ARP Factory Authorized Service Center in San Francisco during the mid-1970's, and was trained at a factory class in Los Angeles by factory service representative Fred Dodd [Phil Dodds], who played the role of the synth guy in the 1977 film "Close Encounters of the Third Kind". Included are original blue line and blue prints of schematics, factory service notes, my personal notes, advertising brochures and posters, etc. gathered when I had my repair shop in the San Francisco area. Though San Francisco's synth guru John Vierra blew the doors off the competition back then (myself included), I went on the burgeoning field of "Personal Computers" in which I prospered well.

All documentation is in very good to near-mint condition with no missing or unreadable pages. This is my personal collection of service and support documentation from ARP which includes support information for:

* ARP Omni model 2480
* ARP String Synths models 2600-2606, 3620, 2300
* ARP AXXE model 2300
* ARP Pro Soloist model 2701
* ARP Odyssey models 2800, 2810, 2811, 2812, 2813
* ARP Sequencer model 1601

Shipping will be in a 12 x 12 x 6 box weighing about 8 pounds."

Mutronics Mutator

via this auction

"The Mutator is a stereo analogue effects unit based on technology developed for synthesis in the late sixties. Quite unlike your standard reverb, delay, chorus and flange type effects the effects achievable with the Mutator are unique and quite simply defy description.

The Mutator is a stereo analogue filter and envelope follower with full control facilities. It contains two independent voltage controlled filters similar to those found in analogue synthesizers, which can be used to treat any external sound source. Each filter can be controlled from its own associated low frequency oscillator (LFO) and/or its own envelope follower section, which extracts the envelope contour of an input signal and applies it to control the cut-off frequency of the filter.

Each envelope follower can be switched to track either the envelope of the sound that is being treated by the filter, or that of an independent external control signal. This external control signal can be any audio source , eg. a drum sound, a guitar, a synth, a sampler output, or even a microphone. Thus the envelope characteristics of one sound can be superimposed onto the filtering contour of another.

Another switch on the envelope follower selects envelope follow mode or gate mode - in which the circuit detects whether a signal is above a certain threshold level before switching on.

In gate mode, the device can operate much like a dedicated noise gate unit, with the added capabilities of the analogue filter

The LFO's have four different sweep waveforms each and may be switched via a stereo link to produce stereo panning effects."

Hartmann NEURON Survival Kit : Motherboard + 250GB HD

via this auction
" This Kit includes :
* One drop in replacement motherboard
* A new pristine Hard Drive breed ! This is your rare chances to get, for this powerful machine, an extended 250GB version of the original Hard Drive.

Original Hard Drives found in the NEURON were usually within the range of 20GB minimum up to 80GB maximum in some occasion. The provided Hard Drive in this auction is resulting of my intensive works to extend the last Linux partition while keeping all the original linux operating system information safe. The resulting Hard Drive is a 250GB unit from Western Digital, well know for it's silent and cool operation.

As a consequence, the available space for all your Models and Sounds comes up to 230GB. Here this noticeable improvement will relatively cost you as much as some 80GB hard drive clones that were sold here on ebay some months ago. Keep in mind that this is more than just a clone : All of the original NEURON hard drive has been analysed in details such as the Boot records (Mater and Extended ones) and allmost of the original partitions in the respect of the original information close to the byte ! Such an evolution could not be affordable using standard tools such as driveimage, partition magic, nor Acronis, but thanks to my own Linux know how.

Consequently, this auction is for you the occasion to provide your NEURON with a large significant space for your creation, models and sounds, but also the occasion to insure of a second 'Life' for your machine ! : NEURON users community has reported some of the original Hartmann motherboards going dead because a batch of bad components described as the 'Capacitors Plague' . It causes (we will see further occurences of this problem in the future, so it may hit your own neuron motherboard also....) a chemical decay of some of the inner PCB layers. A a consequence, I strived until I found out The motherboard type that fits exactly as the original design as well as its respective shape factor. This new motherboard will run exactly as your previous board. This new board may help you in fixing your Neuron if it's currently faulty, or represents a backup for the future. Keep your Ram, your processor, your Fan as they are since all of them will fit with this new board. Hence, No RAM or Processor upgrade of any sort on your side is needed. The provided motherboard in this auction has been tested and validated within the NEURON Synthesizer : It will run exactly as the original motherboard design (which was the Shuttle Spacewalker MV25). BIOS and Jumpers configuration have both been entirely pre-configured.

> It's a 'plug and play' combo , as soon as it reaches your door.

The hardware is provided with some instructions about how to install the motheraboard, what to connect and where, etc. The extended 250GB hard drive comes into your NEURON synthesizer as was your original drive the first day in, with ModelSet v4 , SoundSet v4 and OS 1.5 all installed."
