1972 Moog Minimoog Synth Brochure
"Extremely rare brochure from 1972. 8 1/2 x 11", 4 pages. Extremely bad graphic design. A little water damage and a pen doodle on the front. The inside features photos of Minimoog users, including Keith Emerson in full Rock God mode. I like the guy in the tux, I wish I could have caught his act."

Mattson Mini Modular Perched on a Synthesizers.com Modular

The MMM Phoenix series on top of a Synthesizers.com modular at this year's PNW Synth Gathering. Image via Carbon111 in this VSE thread. Be sure to check out Carbon111's updated Syntar page now with the MMM. The modules on the MMM are all the same size whereas the synthesizers.com varies based on the modules. The dotcom uses 1/4" jacks and is based on the MOOG modular. The MMM uses 1/8" jacks and is based on the Syntar (more info on Carbon111's site).
click the image for the full size shot.
Note the MMM pictured is the base system at 12 modules. You can add an aditional 12 modules on the right for 24 modules total. The PSU and MIDI to CV take up two spaces in the default system and are used for the additional 12 modules. You can latch on additional cabinets and each system can be folded into a closed and protected modular suitcase for on the go.

trash_audio - artists and their workspaces

Richard Devine:
"I have been working on music for almost fifteen years now. I started when I was 16 just recording tons of strange sounds and things to tape, then I eventually moved to working with digital samplers in the early 90’s. From there I progressed to working with computers and digital signal processing. I have always considered my self more of a sound collage artist. Dealing more with sound design, and creating an unusual space or experience for the..."
The Thomas Henry Mega Percussive Synthesizer
via Scott Stites on this electro-music thread. Keep an eye on the thread for updates. If images or samples come in, let me know.
"I guess I better extricate this from the Clangora thread before it derails that fine conversation. I hope I don't sound like I'm hyping this thing unnecessarily, but I truly am buzzed by this design. This one has been as hard to keep quiet about as the Mankato Filter. In fact, I often think about this as the Mankato of drum voices, it's that good. I'll start at the top:
This summer (summer 2007), Thomas quietly developed a drum voice that just sat me back in my seat. I'm not sure I've ever seen him work so hard on a single design - I'm sure he has, but in my experience breadboard testing things, I'm certain this one took more work than I've experienced with any other project. He literally designed this thing from the ground up, and we very thoroughly rung it out.
In the Clangora thread, Thomas mentioned how versatile it was (and it is extremely versatile). On top of that, the sound of this drum voice for me is simply stunning. A good deal of that is due to an innovation Thomas threw in there; it's something that I've never seen on any other drum voice. It was an idea that he picked up from an interview with Roger Powell years ago (it was Roger Powell, wasn't it Thomas? I'm kinda fuzzy here). It has to do with the impact circuit - I swear, it literally sounds like someone is striking this think with a real stick/mallet/hand/sledgehammer (depending on how it's tuned).
Just to give a rundown of the elements: the voice has three oscillators, a noise source, a balanced modulator (that can be unbalanced as well), three envelope generators, two VCAs, a noise source, a LP/BP switchable resonant VCF, and a versatile mixing section with send/receive loops. This one is a blast to tweak as it plays, BTW. It's the only drum voice I've played that can dissolve from a cowbell to a landing alien craft in a very non-seventies, non-disco-era Simmons way (though it can do that, too, if that's your thing).
Fortunately, Thomas designed it, so it is a very elegantly designed circuit (translation, it will fit on a single PCB). There are a lot of controls, so it won't be a small panel.
Right now, the target for the project is as the next electro-music PCB series, in the same vein as the Klee project. We're working on drafting a certain man from Nambucca Heads to crank out a PCB, and we're going to Klee team it to make sure what you get will be the best quality PCB we can offer. The documentation part already is very well done - can't beat those Thomas Henry schematics! I'm hoping to avoid the whole reservation process which is really a pain, but this is all in the prelim stage so far.
Expect samples. Very Happy
Cheerio,
Scott"

Jomox Sunsyn Demos and Mini Review
Matti posted the following on the Analog Heaven List. I asked him if I could put up a post and he gave me the ok along with a few more audio samples to put up. Thanks Matti! The Sunsyn is probably the one high priced synth I still really, really want. I was fortunate enough to play with one in person and I really liked the sound of it. What's interesting is it reminded me of the early Oberheim SEMs as well. That said here are some words and samples from Matti:
"In short, I love the Sunsyn. If I had to compare it to an another synthesizer, well... Like you all know, talking and writing about how one experiences sound isn't that easy, but I'll give it a shot.
IMHO, the Sunsyn has a little bit of that early discrete Oberheim sound, but the tonality also reminds me of some modular systems. I have never played an early Obie and I have only a little experience with modulars, so this is opinion is largely based on recordings and demos I've heard.
In general, the sound is clear, defined and very much "alive". It doesn't always sound very "vintage-ish", but the sound is 110% pure analogue (unless you use the RCOs). One thing that makes the sound comparisons a bit hard, is that the filter is very configurable. You can easily make different timbral variations (softer, harder) of the same sound just by tuning the individual filter poles. Here's a couple of softer, PWM Sunsyn sounds:
If you are thinking about buying a Sunsyn, I really recommend trying before buying. Although I really love the sound and interface, I know there are people who don't. Some people have even compared it to a VA. My main gripe with it is that it's very picky about the MIDI signal it's receiving. some controllers and sequencers just don't go too well with the sunsyn. Otherwise, I haven't had any problems with it. Not even with the multimode. For me, the price was totally worth it.

JH Triple Chorus Sring Ensemble Available for Order

"Hi,
I'm now ready to take orders for the Triple Chorus PCBs.
(See this link for details about the project.)
Pricing is EUR 27.00 per board,
plus a single EUR 4.00 shipping flat charge for worldwide shipping, regardless how many boards you are ordering and where you live. It does *not* include any customs fees or tax that you may (or may not) have to pay in your county.
What you get is a double-sided printed circuit board with component overlay, approx. size 160mm x 100mmm.
You have to buy the electronic components for this, and build the device, yourself. (Check the above website regularly for updates and building hints, bill of matrials etc. A PDF with the component overlay is already there.)
Most components are easily available and cheap standard parts. In addition to that you need 3 (three) TDA1022 chips. These are BBD chips that are no longer in production, but which are still available as I type this.
Important: I am having these PCBs custom-made to your order - it's likely that there will be only one single production run. If you're in, you're in - if not, you're not. I have no influence on the availability of TDA1022 chips, however, so if you place an order, I expect you to actually buy the PCB, and make sure for yourself that you get the required ICs.
I'll wait for the orders to come in for about 2 weeks from now, so you can check the availability of the ICs.
Estimated time line:
2 weeks for taking orders
2 ... 5 weeks for PCB manufacturing and verifying
Call for payment (don't pay before you get that mail!)
Shipping of boards when payment arrives
If you want to place an order, please send me an email (bottom of this page) and use the FOLLOWING FORM (fill in your data instead of [], for instance: "2 Boards" instead of "[quantity] Boards")

David Bowie - Ashes to ashes
YouTube via marychild.
The question as to what synths were used for the end of Bowie's Ashes to Ashes came up on this VSE thread. The below was uncovered. I'm curious if this is actually in reference to the main line that runs through the song. Note Steve Strange of Visage (who also included Midge Ure and Billy Currie of Ultravox fame) is the left most extra of four when they first appear.
via Marching Pig on the VSE thread:
"Wiki has this to say:
'Perhaps Bowie's most sophisticated sonic work to date, its choir-like textures were created by Chuck Hammer with four multi-tracked guitar synthesizers, each playing opposing chord inversions; this was underpinned by Bowie's dead-pan, chanted background voices.'
Though, I've also read that they recorded it, and made 4 copies on tape; 2 were played "right side up", one backwards, and 2 were played with the "wrong/bottom side" up, again, with one of these backwards. Though, just thinking about that makes me think it's just plain wrong.
the page on Chuck Hammer, it says this:
"In March 1980, Hammer recorded guitar-synth tracks for David Bowie on the album Scary Monsters (and Super Creeps), including multiple textures across "Ashes to Ashes", 'Teenage Wildlife' and 'Up the Hill Backwards", all of which marked the earliest use of guitar-synth in Bowie's catalogue. The actual instruments utilized on these tracks included a Roland GR-500 with an Eventide Harmonizer. Textural tracks such as those on 'Ashes to Ashes' exhibited a multi-layered, approach, to recording and composing with the guitar.'"
AudioWeevil07 Prototype Demo
YouTube via BugBrand.
"Here's the 1st demo of the new AudioWeevil. This demo is just using the internal speaker, so the sounds are quite gnarly! Also, the soon-to-be-released version will have a few more features in there (mainly adding to the modulation LFO).
The demo begins with no-input Weevil-ing & touchyness and then moves on to plugging a Hohner Pianet through the box for filtering and noisy ringmod action.

"The Korg DW8000 is the bigger brother to the DW6000.... It was released a year or so before the M1. Have analog synthesis sections... with very nice filters... this DW8000 model doubles the waveforms of the DW6000 to give you 16, doubled at 2 per voice to give 8 note poly of 2 osc' voices........ but..... Like the 106, you can do a Unison mode to stack the 16 oscillators !... The 8000 also has excellent Korg analog filters... they go to self-resonance for squeel-appeal. The 8000 even has an onboard arpeggiator which can clock to midi, and is velocity & aftertouch sensitive.... Other features include Midi In, Out and Thru; cassette interface; stereo outs; foot switch control for patch changing, portamento and sustain; 64 memories; aftertouch keyboard; arpeggiator and ... yup !!....a built-in digital delay unit."

Marion Systems ProSynth

"Marion ProSynth Analog/Digital Synthesizer
Built in 1996 By Tom Oberheim

I had read in keyboard magazine that Tom Oberheim was designing a new synth module. I was a fan after listening to his earlier Oberheim synths. I later saw an advertisement in keyboard magazine that the synth was completed and shipping. I called the listed phone number to order the Marion prosynth and got a answering machine. Later that day I got a return phone call and to my surprise it was Tom Oberheim. He said he would put one together for me. I asked him to sign it for me and he did. It has been in my studio ever since."

Oberheim OB-12 Review on Celiar Structures

One of the reasons claimed by those who dislike it is that "it is not a true Oberheim". That's mostly true because it seems that no one of those who worked At Oberheim Electronics was involved in the creation of this synth, but that doesn't means it's a bad synth at all."

John Bowen Solaris Upate
"From the Planetz forums...
[John Bowen]:
'An update on pricing and availability has been posted on my Purchase page.
Here's an excerpt from a message I sent to all those who had made pre-order deposits, to clarify the situation:
"Klaus is the ideal candidate to oversee the conversion and upgrade of the special Scope modules that I hoped to add to the Solaris system (even though we originally had no idea we would one day have access to these). This last point is important, in that the process is not nearly as simple or easy as I thought it would be, and in fact, has caused a bigger delay than I expected.
"When I arrived in Germany last week, it was clear that I had a choice - either release the Solaris around late December (as I've been planning) but without the Minimax, SSM, and CEM filter (and oscillator), or give it more time to get the 'goodies' from the Scope library that I had wanted...
"So, this is where we stand: I am going to take more time on it, to give Klaus plenty of opportunity to get things as best as possible, because we all desire to have a product that holds to the high quality and excellence that has been at the core of what I've always tried to represent in my products. This delay will add 3 months to the schedule, with production starting in February and delivery as soon as possible thereafter (end of Feb. or early March)."
cheers,
john b.'"

Audio was recorded on the laptop soundcard, mono since the unit FX is bypassed (the synth is mono but the FX unit is stereo). Mp3 sounds of the videos are available too and I made some extra mp3 files. I tried to upload to YouTube but so far it doesn't work, seems there servers are having pb.I'll try later or tomorrow. Meanwhile here is the link."
I will put the YouTube vids up as well, as they go up. Thanks ScillonS!

Tweaking the Paia 9700S
Sequential Circuits Prophet-5 Manual from 1979
"Written by Tom Darter in 1979, it's a loose leaf three ring binder with a clear vinyl cover. Contains patch sheets of all the factory presets, as well as several blank patch sheets, which is a bit odd considering that it was one of the first fully programmable synths. It says that this is Model 1000, so I don't know what Rev Prophet this is for. I assume it's one of the early ones."
