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

Welcome To MFOS, Your Synth-DIY Headquarters. What is synth-DIY? Synth-DIY is just what the name implies. Synthesizer Do It Yourself. Many people, like me, grew up in the dawn of the analog synthesizer age (Moog, ARP, Oberheim, Buchla, RCA, EMu, Fairlight, PAIA and many others) and although we may have really wanted our very own analog synthesizer with dozens of knobs and switches they were w-a-a-a-y out of our reach financially. Now many people with a modicum of electronic skills and a renewed interest in analog synthesizers are discovering that with a schematic, a PC board and some electronic components they can do it themselves!. MFOS' mission is to help people realize their synthesizer dreams. We do this by providing analog synthesizer projects with complete schematics, assembly drawings and professionally manufactured PC boards. If you already have electronic skills... welcome! If you would like to learn more about electronics or analog synthesizers then try these links: How can I start learning about electronics?, Analog Synth 101 and/or The MFOS Book Store. It's never to late to develop a new skill, reignite an old passion or exercise your creativity. Keep imagining, keep inventing, stay ingenious.

235 MATRIXSYNTH: Alesis Andromeda A6 Aurora Mod
This was a custom mod. I originally put a post up in August of 05 here. Anyone know the website where more info on this mod is hosted? I accidentally lost the link when mucking around with Blogger's settings a while back. This image via Photobucket Update: I found the original site but it is down. Some info and additional shots pulled from the Internet Archive Way Back Machine. You can find some thumbnails there, but most give you a 404 if you click on them for the larger shot. I pulled the large pics below before they are gone forever. "Alesis made Synthesis History when they released their Alesis Andromeda A6, an analog polysynth bred with new technology and classic analog sound! Sixteen awesome voices with two types of filters, a vast modulation system, and enough bells and whistles to make the Andromeda A6 THE most highly featured analog polysynth in existence. If it only had a sloped panel... SPECS: * Take one Andromeda, lightly used (but out of warranty - very important!) * Add one black on blue BETA Panel - because the pre-production beta panels were lacking the Pre- and Post-Filter Mix VIEW buttons, either the buttoncaps must be pulled off of the switches on the PCBs OR two holes need to be carefully drilled through the panel to accomodate. I drilled the holes after measuring about fifteen times each. * Tilt that panel at approx. the same slope as the Korg MS-20. Requires the extending of a couple of ribbon cables inside, and some pop-rivetted braces. Not too hard. * Custom wood endcheeks of nice Oak, plus a wood accent over the keyboard. I chose to go with thick, high quality wood to make Aurora more of a beast. * Replace all green LEDs with red high-intensity ones. This also required changing some resistor values to increase the brightness. * Replace the LCD with a Hantronix Blue-on-White display. Also, some resistor changes are needed. * Have a very agreeable Alesis burn a custom Boot EPROM with the custom-designed bootup screen below. * Build a custom top panel, complete with several additional controls (two joysticks, several switches and knobs) as well as a full 16-channel mixer with level and pan per channel, one for each of the 16 individual outs on the Andromeda. * Add lots of careful, hard work and time, and PRESTO - you have the Aurora A6! The Name: I went with Aurora for a couple of reasons. 1. Alliteration - AurorA - AndromedA - get it? 2. There is some legend/lore as to how the Alesis Andromeda got its name. Could be related to the Greek mythos. Could be related to the Andromeda galaxy. Could be darts thrown at dictionary pages :-) In any case, Aurora fits with the mythology bent because in Roman mythology, Aurora was the goddess of the dawn (Andromeda was rescued and married by Perseus in Greek mythos). Aurora also fits the 'celestial' thing as well, as the Aurora Borealis. Either way, it kept with what might have perhaps been Alesis' reasons for naming the Andromeda. 3. I just liked it. 4. The A6 is kept because this fits with Alesis' naming convention (QS8 = 81-key QuadraSynth, A6 = 61-key Analog). There is some rumor that A6 was a play on ASICs, the custom chips within Andromeda, but I'm assured this is just rumor :-) "
