Jim Patchell's DIY Synthesis

Many of you might recognize the name Jim Patchell. For those of you that do not, Jim is about as respected as it gets in the Synth DIY community. He started his first synth project back in 1973:

"Well, this project was started in 1973, or there abouts. I was at Santa Barbara City College at the time. The library there had Radio Electronics magazine, and I would go there to read and do home work. When I saw the article on building your own synthesizer, I was hooked immediately. This was, of course, the legendary Paia 2700. Some of the circuits were build as is, others I didn't like. The VCO was one of those. I used the national semiconductor application notes for the LM324 to build the voltage controlled triangle oscillator. Back then, I had no money to speak of, so everything was pretty much built from salvage parts. The LM324 was a free sample. They were not cheap back then. I did buy some LM741/747/748 type opamps to make some of the modules. All of the transistors were salvaged. Pots were a very strange collection of pots salvaged from old radios (I could kick myself for that misdeed)."

Plan B releases two new MMModules :)

Two new Plan B products wil begin shipping in two weeks:

1) The Model 9 Mixer/Attenuator is the forth in a series of utility modules from Plan B. A truly modular, multi-tasking 5 in, 3 output mixer, it's balanced inputs are suited for either AC signals or DC control voltages, or both simultaneously.

Along with these mixing options, each of the four main inputs channels are fitted with dedicated Attenuator Outputs which allow access to the leveled output from each channel by itself, independent of the mix. Many thanks to Plan B Norman Fay for thestellar idea of adding independent post fader outputs.

Go here for details.

2) The third in our utility module series, the Model 29 Dynamic Mult is a unique 1-to-5 signal splitter in which four of the outputs are equipped with manual level pots, allowing for both contour control and signal distribution. The perfect companion for non-attenuated VC inputs, the Model 29 requires no power supply connection to operate as it takes it's ground reference from the cables patched into it.

"Hello All!

My name is Michelle Moog-Koussa. I am the Executive Director of the Bob Moog Foundation. located in Asheville, NC. For those of you who are not familiar with Dr. Moog's work, he was a synthesizer pioneer, largely credited with inventing the first synthesizer and changing the face of music forever. Dr. Moog lived and worked in Asheville for the last 25 years of his life and passed away in August of 2005. We created the Bob Moog Foundation soon after that and received our non-profit status in March 2007.

In January of this year, we went through Dr. Moog's extensive archives, which include 50 years of prototype instruments, photos, schematics, articles, notes, correspondence, vintage recording equipment, reel to reel tapes and other historic ephemera. Unfortunately, Dr. Moog stored this unique, historic and fascinating collection in a hot, humid buidling out in the country and everything is covered with mold. Additionally, time has taken its toll on just about every item. With the help of a core group of dedicated volunteers, we have moved the most important materials into a climate controlled storage space in Asheville. We have begun to seek help in preserving this important collection.

We are presently in the midst of applying for a grant from the Grammy Foundation to help us retore the reel to reel tapes and the vintage recording equipment. The Grammy Foundation requires that we find a qualified archivist to help us with this project. If you are an interested archivist with knowledge of reel to reel tape preservation, please contact me immediately.

The grant application is due on October 1st, so time is of the essence. Please respond at your earliest possible convenience.

Thanks so much for your attention to this matter.

Sincerely,
Michelle Moog-Koussa

Limited Edition Akai MPC 4000 via Guitar Center

"GUITAR CENTER INTRODUCES HI-TECH CUSTOM SHOP FEATURING UNIQUE ELECTRONIC MUSIC ITEMS ESPECIALLY DESIGNED FOR TODAY’S ARTISTS
Limited Edition Akai MPC 4000—Exclusively Designed By Master Customizer Bruce Forat—Is Premiere Offering

Westlake Village, CA: Guitar Center, the nation's leading musical instrument retailer, announced today the introduction of its exclusive Hi-Tech Custom Shop. A new model for the retail chain, the Hi-Tech Custom Shop gives musicians unique access to rare and specialized items designed to break the homogeny of mass-market gear. The planned inventory for the Shop includes limited custom editions, exclusive product and artist-endorsed items. These will be conceived and designed by industry experts to celebrate the legacy of genre-defying pieces as well as appeal to musicians with a desire to own a piece of history.
These exclusive collaborations will be on display at select locations but can be special ordered at any Guitar Center nationwide.

To launch the Hi-Tech Custom Shop, Guitar Center purchased the last eleven Akai MPC 4000s ever made and partnered with Bruce Forat, who has been at the forefront of music electronics for the last 25 years. Forat, who has personally customized drum machines and keyboards for top musicians including Prince, Dr. Dre, Jermaine Dupree and Madonna, customized the eleven to create one-of-a-kind MPC 4000s, of which only six remain for sale exclusively through the Guitar Center Hi-Tech Custom Shop. The Akai MPC series, used by influential musicians and producers such as Kanye West, Just Blaze, and Pete Rock, has been instrumental in the development of hip-hop music and is widely regarded as the industry’s gold standard. Additional information can be found at www.guitarcenter.com/forat.

“For the launch of Guitar Center’s Hi-Tech Custom Shop, we wanted to offer something incredibly special,” said Tony Baraz, assistant buyer for Guitar Center. “The Akai MPC is iconic in and of itself, but when customized by a monster talent like Bruce Forat it is a work of art.”

“To make each of the remaining Akai MPC 4000s truly unique we headed to the Caribbean for inspiration,” says Forat. “There’s something about the atmosphere and cool breeze that gets the creative juices going—I count these Hi-Tech Custom Shop MPCs among my best work.”

Sequential Circuits Prophet-600

images via this auction.

"The Prophet-600 is a 6-voice polyphonic analog synthesizer with a 5-octave, 61-note (C-C) keyboard. Each voice consists of two VCOs, two VCFs, and two VCAs. Each of these components has its own independent ADSR envelope. Each Prophet-600 voice uses 2 sets of Curtis Chips for its architecture. The sound originates in a pair of Curtis 3340 VCOs, each with independent on/off switches for sawtooth, triangle, and pulse waveforms. VCO1 can be synced to VCO2. Both oscillators are set with a frequency knob that is notched in semi-tones, with a separate fine tune knob for VCO2. Portamento is adjusted by a single knob. The sound then passes through a pair of Curtis 3372 chips. Each 3372 contains a VCF, a VCA, and a separate volume control for mixing. The VCF is a resonant 24dB/octave filter, with its own ADSR and knob for frequency. The frequency knob is quantized into steps, not allowing you to change it smoothly. Key follow can be set to full, half or off. The LFO can modulate the oscillators (both at the same time), the filter frequency, and the pulse width on the oscillator. The Prophet-600 has mono mode with chord memory as well as two one-track sequencers and an arpeggiator. The sequencers are programmed in real-time and cannot be edited. The arpeggiator can be set to the normal up or down modes or can cycle through the keys in the order that they were played"

"Great Looking 1970's Vintage Roland SH-2000 Analog Synthesizer Keyboard. It was found packed away in storage at a local Estate Sale. I doubt the previous owner has played it within the past few years. Its in Very Good/Excellent condition cosmetically, all knobs & controls are original & intact. Its been well cared for by the previous owner. I've tested all the functions, playing it through my amp, and it works fine. You may choose to have it cleaned, since it sat unplayed for so long."
