Keys of the 70s

Strings & Things Memphis advert for keyboards circa 1977.

Been looking through some mid-70s issues of “Contemporary Keyboard” (h.f. “CK”) magazine.  CK later became simply “Keyboard,” which is still in publication; it’s part of the GUITAR PLAYER family of publications.  NEways…   1976/7 was an interesting time in the development of keyboard instruments.  Affordable polyphonic (IE., you can play more than one note at a time) synthesizers were still a few years away, and realistic-sounding electronic pianos were still about a decade away.  So what you had was a very mixed bag of Electronic Pianos and ‘String Synthesizers,’ which are both basically hyped-up electric organs; some still-useful electro-acoustic instruments; and a pretty wide range of pretty experimental synthesizers, many from small manufacturers that didn’t stay around very long.  In about 6 years this would all be blown away by advanced Japanese synths with built-in programming, patch memory, and all with polyphony;  the Roland/Korg/Yamaha DX7 era; and this too would fall at the hands of the dreaded Korg M1, which ushered in the Rompler era.  Anyone out there using an M1 lately?

The ARP pro-soloist, typical of the ‘preset’ synths of the era; preset synths offered interfaces optimized for live-performance rather than endless tweaking in the studio.

The Hohner Clavinet, HIP II, and Stringvox.  The Clavinet has attained classic status, and many are still in use; not so sure about the HIP II and Stringvox.

A couple of Moogs from different ends of the spectrum.  The Minitmoog was a ‘preset’ synth; the Polymoog was not a true synth; it was closer to an organ in terms of its basic operating principle.

Oberheim Expander

A few Paia synth-kit offerings of the mid 70s: the Surf Synthesizer, The Gnome, and the classic 4700.  See this link for previous PAIA coverage on PS dot com.

An advert for the Polyfusion System A.  See this link for previous coverage of the Polyfusion line.

The RMI Electra Piano.  When we were growing up in the late 80s/early 90s, ‘electric pianos’ like these were about fifty bucks or less; no one wanted them, and that has not changed.  They sound pretty awful but they’re still heavy and cumbersome!

The RMI KC-II Keyboard Computer.  From what I gather, this device is essentially a RAMpler; not too different in basic principle from the epic Synclavier in that the user could input waveforms which would then be manipulated.  This thing apparently cost $4700 which means that… yeah… there ain’t too many out there.

Roland MP-700 electronic piano

Sequential Circuits Model 700 programmer.  I assume that this thing has a bunch of jackpoints that you would connect to various I/O points on yr modular synth…  anyone use one of these?

The Steiner-Parker Synthacon.  A rare Minimoog-esque unit.  Apparently used on IN THE LIGHT.

The Strider Systems DCS1.   I can’t find any info on this piece.  Anyone?

Synare PS synth drums

Yamaha CP-30, yet another electronic piano

The Yamaha YC-45, the flagship model of their YC series.  The YCs are unapologetic “Combo Organs,” which explains why they are still in use while the string synths and electronic pianos rest mainly in landfills.  These are great-sounding, versatile organs; they also weigh a metric tonne so be forewarned.

Want more?  Check out this site; this man has dedicated his entire blog to territory that I only dare visit.

Tomorrow: some interesting keyboard amps and FX from the era.

makin’ it

What is goin on here !?

The May 1979 issue of DOWNBEAT magazine has a short article on the subject of Do-It-Yourself synthesizer kits.  I’ve uploaded a scan of the entire article as a PDF below.  Much of the article focuses on kits from Paia.  Paia, if you are not familiar, is a very long-running company that makes audio kits.  One of my earlier experiences building audio electronics was constructing their Theremax Theremin. I got the Theremax together in about a day, and it worked right away. No issues.  I used it (mostly as a performance voltage-controller) for about a decade before I sold it at a moving sale.  It was a good, reliable piece.    I know that nowadays there are a lot of cheap theremins on the market, but 15 years ago it was a pretty unusual item.

Anyways…  PAIA still makes and sells descendants of the synth modules that are described here, and the prices are extremely reasonable.  A time-honored way of getting into audio electronics.

btw, dude in the pics here is not me, but it might as fukking well be.

Vintage Moogs in Deutscher Sprache

From the PS dot com archive/pile:  Download nine pages of German-language Mini Moog and Moog Sonic-Six catalogs from 1974.

DOWNLOAD: Moog_Germany_1974

Also includes Moog German price-list of the era.

The Mini-Moog synthesizer was introduced in 1970.  It was a truly revolutionary device.

Keyboardist Rick Wakeman says of the Minimoog’s invention: “For the first time you could go on [stage] and give the guitarist a run for his money…a guitarist would say, ‘Oh shit, he’s got a Minimoog’, so they’re looking for eleven on their volume control – it’s the only way they can compete.” Wakeman said the instrument “absolutely changed the face of music.”

(Source)

Essentially, the Mini Moog was the first widely-available ‘performance’ rather than ‘studio’ synthesizer instrument.  The distinctive sound of the Mini Moog is due its 3 available oscillators (most vintage analog monophonic synths have no more than 2) and its 24db per octave filter (in contrast to the less-aggressive 18db per octave filter of its contemporaries).

The Moog Sonic-Six was similar to the Mini Moog, but it has only two oscillators.  Its ‘institutional’ design and built-in amplified speaker highlights its intent as an educational instrument.

Music Synthesizers in Popular Electronics 1972

Download a five-page article by David L. Heiserman on “Music Synthesizers And How They Work” from Popular Electronics magazine, February 1972.  Also included is a brief description and schematic for a ‘surf synthesizer’ project.

DOWNLOAD: SynthsPopElecFeb1972

Nice images of the Putney Synth and a Moog IIIc.  This article offers a very broad treatment of the subject, and it does not discuss music or music aesthetics very much; it is interesting though because it is intended for an audience with some technical savvy.  Everything in this piece can easily be applied to gaining a greater fluency with the software synths that we use today.

Naturally, any discussion of ‘music-synthesizers’ in Popular Electronics had to be followed by some sort of audio-synthesizer project; since this is 1972, the project is a Surf Synthesizer, aka a white-noise generator followed by a randomly-modulated low pass filter in sync with a VCA.  If you know what any of that means, you might could be interested in the schematic, which you can find after the link below.  I can imagine sitting at the kitchen table during the Nixon administration, carefully soldering this mood-enhancer while my wife macrames an Owl.

Out-Of-Print-Book Report: History Of Music Machines (Smithsonian)

Came across this obscure volume in a rubbish bin several years ago.  Published by Drake Publishers in 1975 and billed as being ‘Prepared By The Smithsonian’ (No author attributed), “(The)History Of Music Machines” (hf. ‘HOMM’) is a b&w hardcover gift/coffee-table book which presents a fairly interesting survey of the history of reproduced sound.  Several copies are available for just a few bucks at amazon. 139pp.

From the introduction (by writer Irving Kolodin):

“Over the years, the debates have continued about the pros and cons of music machines, the impact of their existence on the habit patterns of society,…. their influence for good and evil on taste…  As for taste, it has been driven to the wall, and all but through it, by exploitation of the music machines’ potential for serving the lowest common denominator.  Whether in records, or in radio’s reliance on the Top Forty -those loudest, hardest, often cheapest appeals to the beetle-browed-  selectivity has since foundered on the rock of commercialism.”

Jesus Irving.  Don’t mince words buddy.  Tell us how you really feel.  Note how he allusively slips ‘Be(e/a)tle’ and ‘Rock’ in there.  Nice one.  ANYhow. Reactionary sentiments asides, HOMM is basically a chronological series of photos with explanatory captions.  I find it interesting because it does not attempt to parse recording devices, electric instuments, synthesizers, amplification equipment, choosing instead to include all of these very different (in my mind, at least) type of equipment into the totality of ‘music machines.’  This suggests the view point that music is either made ‘by man alone’ or somehow made ‘by machine.’  It’s an interesting idea.  A very outmoded binary opposition, certainly.  Here are some highlights.

The multiphone, a wax-cylinder jukebox from 1905.

The Stroh Violin.  DS mentioned  last week that he had seen a band in NYC recently that performs exclusively 1900-1930 music on all period instruments.  ‘One of those Violins with the victrola horn’ is apparently employed.  Now we know that this is called a Stroh Violin.

The much-loved Magnecord PT6 gets some praise.

HOMM ends with some (even then very-dated) images of Electronic Music Studios. Above we have the Columbia-Princeton Studio circa 1959 (see my previous post) and below some rare images of the circa ’65 studios at the Catholic University of America.
