MAM MB33 II
via this auction.
sample 1
sample 2
• 100% analog audio synthesis
• VCO : Square wave and Sawtooth
• Suboscillator
• 18 dB low-pass filter like the original TB-303
• Pulse width modulation (PWM)
• Distortion effect
• VCF IN (External audio signals can be applied to the VCF IN socket for processing by the MB 33 II.)
• MIDI In / Out / Thru
• MIDI can send/receive controls for the cutoff, resonance, ENV mod, accent, decay, distortion, and autoslide on/off
• Reso adjust
• Autoslide

Plexus Instruments CR-800

"the only trick with the triggering is the cr8000 voice boards need a downgoing (positive to negative) trigger. this can be accomplished with an inverter, such as a doepfer or analogue solutions inverter module. i wound up using an elby midi-trigger converter, with a reprogrammed pic. the upside is that THE TRIGGERING IS VELOCITY SENSITIVE. this is fantastic, and allows for subtle nuances."

Jim Patchell's DIY Synthesis

"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

Low Pass Filter pictured. He's contributed quite a bit to the synth community. You can see a bit of his work in the following three sites.

Plan B releases two new MMModules :)

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.
Go here for more details.
The 'mama massacre kein sex' project by syndrome
Click here for a number of tracks, in most cases, created by using only one synth. Warning: the title to the tracks may be offensive to some and possibly banned in Germany. I forget if that particular word is or not. I do know it was on the black list for most search engines. This one via Serge.

"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
