1386 Retro Synth Ads: Sound Master Memory Rhythm SR-88, Keyboard 1982
Sound Master Memory Rhythm SR-88 drum machine 1-page advertisement from page 67 in Keyboard Magazine August 1982. Hmmm. Not sure how I feel about this ad. There just seems to be a lot going on. For example, am I supposed to know who "The Rhythm Section" is? The fact that they include themselves in an already long ad title suggests they must be some kind of a big deal. And then you find their name again in the bottom left-hand corner: "The SR-88. Another innovative product from The Rhythm Section by Sound Master Distributed exclusively by JTG of Nashville." So, let me get this straight. JTG of Nashville is the distributor of the SR-88 which was created by The Rhythm Section which is somehow owned or operated by Sound Master. That is waaaaay to much information. Sounds like something political is going on there, and readers unfortunately get stuck in the middle of it. There also seems to be a lot of ad-copy which actually doesn t give me much information. Reason #4 gives readers the most info including instant stop/start, variable tone and output switches, and a write/play mode indicator. The most I glean out of the four other reasons put together is: 16 rhythms, clock pulse and a price of under $200. The actual specs that are probably most important to potential buyers are inexplicably shoved into the bottom right-hand corner. Luckily for me, there are a few resources on the Web with more information about this beast. Unluckily for blog readers, as soon as I started looking for more info, I got swept up in a certain SR-88/Boss DR-55 controversy. Comparing the SR-88 and Boss DR-55 One of the first Web sites I hit while looking for info on the SR-88 was Dubsounds.com. The site includes a great little write-up on the SR-88, but, more interesting was finding out about a little controversy about whether the SR-88 or the very similar Boss DR-55 came out first. The two do seem mighty similar in functionality. For comparison purposes, I did a quick search on MATRIXSYNTH to find more photos. . A great photo of a gray SR-88 can be found in this December 2005 SR-88 MATRIXSYNTH auction post and the less common, but definitely more cool, blue SR-88 can be seen in this January 2011 MATRIXSYNTH auction post. Comparing the two to the Amdek RMK-100 Interestingly, it s not just these two machines that look and function similarly. In this May 2009 MATRIXSYNTH SR-88 auction post commenter "PAC" notices: "Interesting. I have an Amdek RMK-100 (sold as kit), very similar!" Never heard of it, so I Googled "Amdek RMK-100" to see just how similar it was to both the DR-55 and the SR-88. Turns out (according to the Internet) that Amdek products were made by Boss/Roland back in 80s, and, not only that, but that the RMK-100 is actually the kit version of the Boss DR-55. Makes sense on why it would also be similar to the SR-88. I found an ebay auction for an Amdek RMK-100 going on right now with a great photo of the front panel (see below), and indeed it does share a lot with the DR-55 and SR-88 - but definitely not identical to either one. For example, it looks like the Amdek and SR-88 share a similar filler function that as far as I can tell is not available on the DR-55. And the DR-55 and the RMK-100 share a similar accent function that I don t see on the SR-88. Now where does the Electro Dynamics Corporation Programmable Rhythm SR-99 fit in? I also came across another machine with similar features - the Programmable Rhythm SR-99. No - not manufactured by Sound Master, but by Electro Dynamics Corporation. And, it too resembles the others in functionality, and especially the SR-88 in design also. I ve included a row of photos below to help make the comparison between the two. The SR-88 photo is from the 2005 MATRIXSYNTH auction post and the EDC SR-99 photo is from the excellent BigBlueWave.co.uk site. I ve also thrown in a photo from another recent E-bay listing that included both - plus boxes and manuals! Sick! Obviously, Sound Master and EDC are somehow connected, although I can t find any info on the Internet concerning these two companies. I do know that they were both advertising separately in Keyboard Magazine in late 1983, making it unlikely that one of the companies changed their name to the other. Anyone know anything? And then there is the Clef Master Rhythm... Now, I m going to throw in a late entry. It s Sunday night, and I just came across this August 2010 MATRIXSYNTH auction post for the Clef Master Rhythm. It not only shares part of the name of one of the other units ("Master"), it too has many features of the other rhythm machines, and identical innards as the DR-55, but is expanded to include even more sounds: "This is essentially a fully expanded Boss DR-55 feature-wise and tone-wise. The circuits are identical (schematically and tonally) to the Boss DR-55, but the Clef Master Rhythm gives you way more instruments than the Boss DR-55..." Interestingly, according to the post, it pre-dates the Boss DR-55 - and also came in a kit form like the Amdek. "The Clef Master Rhythm came out a little before the Boss DR-55 in late 1979/early 1980. It was sold in two versions and available in greater quantities in Europe than in the United States. One version was a kit that the user put together and another one was a prebuilt machine." A photo from the MATRIXSYNTH post really helps show the similarities in functions with the others: What does it all mean? So, looking at all five machines, its almost like there was a rhythm machine salad bar of some sort in Japan, and each company stepped up to it and picked out which features they wanted to include in their product. And that begs the question - since we know there was a kit form available and there are claims that the Clef Master even has the same circuits as the DR-55, could all five products (and probably others) have used the exact same internal parts - each company choosing which features to include and then customizing in their respective rhythm machine? And if so, were those parts supplied by Amdek, or did all five get their internal parts from some other manufacturer? And if that is the case, then the question of whether the SR-88 or DR-55 came first doesn t really matter much, since it is likely that the kit components would have been available first. Plus, we have that one auction post with the claim that the Clef Master came out before the DR-55 - making it all even more confusing to figure out. Or, am I totally off the mark on all this? Were they all created separately? Maybe I ve just been fixated on this a little too much... I ll keep on looking for more info on these companies and any connection they might have, but if anyone want to buy all four and open them up to take a look - it would be muchly appreciated. :D Posted by RetroSynthAds at 12:05 PM Labels: 1982, amdek, clef master, dr-55, drum machine, electro dynamics corporation, keyboard magazine, rmk-100, Sound Master, sr-88, sr-99 2 comments: Simon said... Here s a funny thing - I seem to remember Clef in the early 1980s as a British company that made electronic pianos (touch-sensitive ones!) in kit form. Deep in the back of my mind I recall seeing them at a music fair in London with a couple of their pianos and some drum machines including a prototype drum/bass/chord sequencer called something like a "Band-Box". But it WAS a long time ago. February 12, 2012 at 12:36 PM Simon said... Looks like (for once) my memory didn t fail me. Here is a 1982 ad for Clef Electronics showing all the products I mentioned, plus a natty-looking little monosynth! BTW, I owned an EDC SR99 drum machine in the mid-1980s, but replaced it with a Yamaha RX-21 a couple of years later. February 12, 2012 at 12:46 PM

884 jh_polykorg_clone
I have started to build a (slightly) updated version of the Korg PS-3200 synthesizer. The PS-3200 was the last of three fully polyphonic, semi-modular analogue synthesizers offered by Korg in the late 70's. (See Ben Ward's excellent Korg PS site for detailed information, including user manuals.) The concept of the PS-Synthesizers was different from other manufacturer's early polyphonic instruments. Instead of using a small number of voices and a clever keyboard assigning circuit, the "PolyKorgs" had a complete synthesizer circuit, hard wired to each key. That makes a total of 48 VCFs, 48 VCAs and 48 voltage controlled ADSRs even for the smallest of the range, the PS-3100. The largest of the range, PS-3300, even had 144 of these circuits. The sheer number of synthesizer circuits called for an extremly economic circuit design, and it's a joy to look at Korg's design ideas which led to building blocks that almost did the same as in the better known "classic" synthesizers. And after many years of engineering and reverse-engineering electronic music circuits, I have learned to look at odd solutions not as "substandard", but as a source of creativity an individual character. Here's a list of some highlights: Function Implementation Side effects Single-Transistor Waveform Converter creates triangle, saw, pulse and PWM from saw input, using one (!) transistor, one diode and two resistors per voice, plus two global control voltages Pulse height also changes with pulse width 5-Transistor-VCF (Korg-35) A Voltage controlled 2-pole (Sallen&Key) LPF built from 5 transistors rather high CV feedthru Single-Diode VC Resonance The dynamic resistance of a simple diode is used to alter the feedback gain of the VCF limited range of Q "Expand" function instead of VCF Envelope modulation depth Instead of scaling down the ADSR with a VCA, the a variable portion of the Envelope is just clipped with a single diode. It's so remarkably close to ordinary VCA function that apparently nobody takes notice. At least I have not read about it anywhere. At slow Atack times, the Envelope appears delayed at the VCF (no effect until th eclipping point is reached). Usefull for Brass sounds, and not easy to emulate with conventional synthesizers. Minimum parts count Voltage Controlled ADSR Three transistors, 1/2 of a LM324 and one CD4007 per voice. Plus some more involved control circuit, shared by several voices Transistors must be selected in 13-tuples, not just in pairs. ADSR detail (1): One-opamp control logic 1/4 LM324 is used as Flipflop, which is dynamically set by Gate-ON, dynamically reset by Gate-OFF, statically reset when the attack peak voltage is reached, and whose set/reset sensitivity is altered by a CV Very odd "Hold" function, depending on the "Attack"-value. But very useful in practise. ADSR detail (2): Single-Transistor, exponential slope VC-Decay Using a single transistor per voice for VC Attack and Release is remarkable already, even though the A and R slopes are linerar. But the Decay slope is exponential, and this is achieved with a single transistor and two resistors per voice! The Decay time range is rather limited. No ultra fast Decay, and no ultra slow Decay either. Single-Transistor VCA That's the "Korg standard" VCA, well known from other instruments like the MS-10.

727 How To Create an Antique Mirror Effect | Apartment Therapy DC
How To Create an Antique Mirror Effect Mclain Wiesand, a Baltimore-based custom furniture company, has made a name for itself by producing handcrafted pieces that capture the feel of real antiques. One of the techniques they use for aging mirror is wonderfully simple and serves as the inspiration for this how to. Creating an antique mirror effect is an inexpensive way to revamp a flea market find, or add a new layer of interest and depth to an ordinary wall mirror. Almost any type of mirror can be aged using this technique, including mirrored plexiglass. Supplies • Mirrored glass or plexiglass. Due to the type of paint applied to the reflective coating, inexpensive, craft-store mirror works wonderfully. • Latex or other gloves for hand protection. • Paint stripper. Most types work fine. For a less toxic product, Citristrip works well. • Plastic putty spreader or putty knife. • Modern Masters Metal Effects Black Patina. This patina solution is essentially an acid that eats at the reflective surface of the mirror. There are probably other products that work similarly, but Modern Masters products work well and can be found online or in most art supply stores or specialty paint stores. • 1” chip brush (or similar brush). • Silver paint of choice. Steps Step 1: (Image 2, above) Wearing gloves, place mirror face down on cardboard or other protected surface in a well-ventilated area. Apply stripper generously to back of mirror and allow to sit for a few hours, or until paint can be easily removed with plastic scraper. It is not necessary for all of the paint to be removed; generally speaking, 80-90% should suffice. When paint has been stripped, wash mirror with soap and water and allow to dry. Step 2: (Images 3 & 4) Place stripped mirror face down on clean cardboard or other protected surface. Dip chip brush in Modern Masters Metal Patina Solution and gradually apply it to the raw reflective surface of the mirror. As mirror tends to age from the edges inward, it is best to apply patina solution in heavier amounts around the edges of the mirror. In a matter of minutes (or less), the patina solution will begin to eat away at the reflective surface. Other application techniques that produce nice effects are spattering and light directional brushing of patina solution. Continue applying solution until desired level of ageing is achieved. Rinse with water to neutralize the reaction and allow to dry. Step 3: (photos 5 & 6) This next step involves reapplying paint to the back of the mirror. The color paint you choose will be visible through the spots created by the patina solution. The dark areas of aged antique mirrors tend to be a dark silver-grey but depending on the silvering technique used, can range from gold to pale silver to black. One method that produced nice results is a combination of dark and light silver paints, applied randomly (per images). Apply paint until the reflective surface is completely covered.

428 Alain Neffe and the Home-Taped Electronic Music Revolution
Alain Neffe launched his first tape label at home in Belgium in 1981. He called it Insane Music Contact and his first installment was called Insane Music for Insane People. Thus began a nearly thirty year foray into home-made, visionary and utterly unfashionable electronic music that has hardly made anyone involved a household name. Insane Music released 55 titles in its most prolific years (1981-87). Five of these were vinyl records and the rest were cassettes tapes. Why cassettes tapes? Magnetic tape was the obvious solution to the problem facing many artists working without record contracts in those days. Cassettes could be recorded at home, produced at home, dubbed at home, and sold or traded by mail. No need for tasteless outside producers and marketing mojo—one needed only leave home to buy more tapes. Says Neffe, “I could copy the tapes on demand. Releasing an LP required that you print 500 copies and 1000 copies of the cover sleeve, and everything had to be paid up front … if the buyer didn’t like the music, he or she could wipe it out and record something else on it.” Mr. Neffe was not the only one out there recording, selling and trading tapes by mail. On both sides of the Atlantic, home cassette technology was permitting the release of much groundbreaking and breathlessly beautiful work, as well as some noxious and otherwise self-indulgent wanking—that coat of many colors we call the DIY (do-it-yourself) Revolution. As early as 1974, Albrecht/d. self-released a cassette entitled Amsterdam Op De Dam in Germany. In 1976, Throbbing Gristle was distributing tapes of their infamous live recordings, and in 1977, the French electro-industrial unit Die Form began releasing tapes on their own Bain Total label. 1980 saw the release of two monumental self-released cassettes, The Storm Bugs’ A Safe Substitute and Colin Potter’s The Ghost Office. In Japan, 1980 saw the release of Merzbow’s first two cassettes, Remblandt Assemblage and Fuckexercise. And in the USA, 1981 saw John Bender’s Plaster: The Prototypes, a laconic and mysterious series of tone and vocal poems. Home taping was not limited to electronic music. R. Stevie Moore, one of the elder living ancestors of the lo-fi rock aesthetic, began releasing distributing home-made tapes via the R. Stevie Moore Cassette Club sometime in the 1970s. And tapes of live punk shows from the era continue to trade hands. Soon, cassettes were coming from everywhere: mysterious PO boxes in the Midwest, to which you sent a blank tape and three dollars and received the tape back with something on it. The Tellus Audio Cassette Magazine was a Fluxus-inspired subscription audio-journal dedicated to music as well as poetry and drama and other forms of audio-art. Zines like Factsheet Five and Unsound devoted entire columns to the material they received from bands on home-made cassette, and demo tapes began leaking to radio stations prior to official record release dates. It was a grassroots movement that marched in association with the self-publication of zines, comics, chapbooks, and other media. The medium had begun to become the message. Insane Music for Insane People (which eventually reached 25 volumes) was a series compiling all home-made electronic music made by artists from across the globe. By including in the liner notes the contact address for each artist featured, Neffe helped pioneer a snail-mail network for those interested in more of what they heard. Artists from all over Europe and the USA, from Japan, New Zealand, and beyond contributed over the years. One could send a few dollars to Insane Music Contact, receive tapes in the mail, write to artists involved and receive more cassettes. Insane Music Contact (now known as Insane Music) has always been a vehicle for Mr. Neffe’s own electronic music projects as well, many of which are periodically active to this day. Though he now makes liberal use of the CD format, Neffe’s artistic approach remains undiluted by years of underexposure. He expects very little acknowledgment of or remuneration for his efforts, which, for him, are emotional articulation, continued experimentation, and purity. It seems nothing but nothing could possibly catapult such heavily uncommercial sounds into the public consciousness–not even this thirty-year retrospective box-set entitled The Insane Box released (ironically, on vinyl) by the venerable Frank Maier of Vinyl-on-Demand Records, an outfit devoted to preserving the precious gems of cassette culture before the evidence disintegrates. For this retrospective (4 LPs + a 7” 45), Mr. Neffe has reached into dusty attic boxes, wherein lay unreleased (or hardly available) material by five projects of which he has been a part: BeNe GeSSeRiT, Human Flesh, Pseudo Code, I Scream and Subject. Each has a unique cerebral orientation and emotional vibe made possible by the combined efforts of invited guests; each runs the high fever of a man very much committed to a personal vision of artistic purity without virtuosity, and each is distinctly French. BeNe GeSSeRiT was not the first of Mr. Neffe’s projects to be recorded and distributed, but is, to my understanding, the genesis of his approach to music as “texts” or “photographs”, or as he puts it, “potlatch music”. On these early tracks we also detect a burgeoning interest in the endless expressive properties of the human voice, both explicitly human and as heavily-treated sound sculpture, both French and English At times, voices shout like besotted Celine parlor workers at each other from tenement windows; at other times a high-pitched female voice wails up and down like Catherine Ribeiro alone in her bathroom. In these tracks, one can also detect the half-digested influence of electro-rock luminaries Silver Apples, the avant-lashings a la Yoko Ono, and occasionally the thunder-beat of early Laibach. Primitive Casio electronics, stage whispers, delay echoes, tape loops, and a certain absurdist humor redolent of Erik Satie, neither dampen the fabric with melodrama, nor detract from the integrity of the grist, nor from the topical seriousness of the text’s subjects. BeNe GeSSeRiT is difficult music, even in the moments that risk elegy, yet it is still more accessible than some of the other Francophone avant-dada outfits of the day, such as DDAA and Étant Donnés, or Nurse with Wound in the UK. Human Flesh is decidedly more structurally cohesive and song-oriented than BeNe GeSSeRiT, and its predecessors and influences are less clear. Still there is a clear interest in the human voice, its textures and timbers when removed of sign value by backwards-masking, and the new textures that emerge when disassembled and reassembled. Even rock-oriented at times, Human Flesh chases a more delirious climax, for the hounds of the carnival are snapping at their heels as they run. This is also a project of varied angles and pursuits, sliding as it does into poetic electro-pop (the supple and Chicago-accented voice of the late Lydia Tomkiw, of Algebra Suicide, appears on two tracks), and moments of Half Japanese-style primitivism. The side-long track “Langsam” is more reminiscent of Piper-era Pink Floyd and Brainticket, as well as other Krautrock, yet is still distinctly French. These early and rare tracks are, in contrast to the more ambitious Pseudo Code and the more intimate recordings by I Scream, more oblique for being a mix-down of materials sent to Neffe from artists around the globe. The track “Sons of God?” is also notable for what is perhaps the first recorded sample of the American fire-and-brimstone preacher Ferrell Griswold, whose voice has appeared in music by Front 242, Phallus Dei, Pragha Khan, et cetera. The cassette medium, for all its benefits to individual artistic expression and culture, is for the selfsame reasons impermanent. Magnetic tape has a thirty year lifespan if properly archived, which means both that preserving their contents in other formats is important, and that paying hundreds of dollars for the original artifacts is a questionable collectors’ pursuit (nevertheless, you can watch it happen daily). With the advent of the mp3 and the efforts of Vinyl-on-Demand and other labels, Insane Music’s CD-r reissue program included, some of this exquisite material has been rescued from oblivion.

229 Typography Is Important - Well-Made Magazine - Techmic Studios
Typography is the art of arranging type and type design. The arrangement of type involves the selection of typefaces, point size, line length, line spacing, and the adjustment of spaces between groups of letters (tracking) and between pairs of letters (kerning). Typography comes from the Greek words typos, which means “mark, figure” and grapho, which means “I write.” It is basically the discipline of shaping written information; thus it can be applied to anything which has to do with text, including web design. Authors write the text, designers and typographers manage the typography, and users read through it.

135 all - dj accessories - Turntablelab.com
we started the Lab in 1998, our first year out of college. Turntable Lab was established in 1998 by Anthony Cattarina, Jasper Goggins, and Peter Hahn. The trio formed the idea for the Lab based on numerous negative experiences at stores that sold dj equipment: both big musical instrument chains and shady Canal Street stereo stores. Turned off by haggling, uninformed salesmen, and questionable product, Turntable Lab built its business on fair pricing, informed reviews, and a well researched selection of “Lab approved” items. Most of the Lab's employees are working djs / producers / musicians, which helps to ensure this high standard. The business model was an immediate success, establishing rapid growth and a dedicated customer base. Turntable Lab soon applied their business model to other areas including recorded music, production equipment, clothing, and books. Each expansion has been met with success, and today Turntable Lab is a recognized tastemaker in all those areas. To bring the Turntable Lab experience directly to consumers, Turntable Lab opened its first retail location in 2001. In December of 2005, Turntable opened its flagship store in Hollywood, California. Currently the Turntable Lab headquarters is located in Brooklyn, New York.
