WAVE KIT SA13 1980 DIY Analog Synthesizer

video upload by Time Tripper

"This is an analog synthesizer that I made when I was in high school.
At that time, it was a transition period from analog to digital, and soon the era of personal computers began. I think this was the last time I touched analog circuits.

German Rackmount Yamaha TG77, TG33, CPX, Synthax RACKWare RG 124 & Kawai MAV-8

via this auction

This one was spotted and sent in via M Me.

Interesting rig. You'll find a picture of the back below with the TG33. This is the first post to feature the Hybrid Arts CPX computer module. Hybrid Arts also made the ADAP SOUNDTRACK SAMPLER ADAP-1. If anyone has any info on the CPX, feel to leave a comment. Curious if it's simply a computer with an editor for the TG77 and TG33, or it's own synth/sample playback module. Take a look at the back below. The Synthax RACKWare RG 124 appears to be the monitor for the system, and the Kawai MAV-8 is a midi patchbay.

It's interesting to see the TG77 and TG33 in a different enclosure.

Williams Synthesiser?

video upload by matrixsynth via Andrew

Update: video above added along with new pics below, via Andrew.

"Explored the internals and it doesn't appear to be a Maplin kit, but looks like a DIY/Handmade."

Andrew went on to mention "It looks like a Dewtron DIY system. The controls are similar to that of the Apollo." [see this post]

This one is in via Andrew.

Note the WilliamSynthsizer on the top right, the 7 x 10 patchpay on the lower right, the massive 12 x 19 patchbay on the left, and the keyboard controller. I thought it might be a Maplin. If so, some massive custom work went into it. It could also be ralated to this synth from 1973's Wireless World magazine. There was also a custom white 5600s which has a larger patchbay compared to the standard square found on most Maplins. Note the one on this Williams Synthesiser is much larger. I could not find a matching keyboard controller.

Andrew plans to open it up and take a look at the inside. He also plans to take more pics. I'll put up a new post when they come in. Until then, if you know what this is, or have any guesses, let us know!

Vintage Drum Machine Demos & Book - RHYTHM MACHINES The Rise and Fall of the Presets

video upload by Momtnz

"RHYTHM MACHINES - The Rise And Fall Of the Presets - by Alex Graham

Rhythm machines – the precursor to what we in the modern age refer to as a drum machine. This book documents the emergence of the preset pattern electronic rhythm instruments that (for a time) were used as a viable alternative to the drummer. Contained within are the Rhythmates, Rhythm Aces, Rhythm Boxes, Rhythmers, Rhythm Kings, Rhythm Masters, Donca Matics, Mini Pops and many more. Nearly three hundred rhythm instruments are documented here, with over two hundred pictures and information provided on their country of origin, instrument sounds, patterns and features. The book is a ‘must have’ for collectors, vintage instrument enthusiasts and recording artists.

For information on purchasing this unique book, follow the links here:"

This is one massive playlist of 68 videos. You can use the player controls to skip around.
The Godwin DM32 gets my vote for best looking rhythm machine.

1969: What Is ELECTRONIC MUSIC? | Workshop | Radiophonic Workshop | BBC Archive

video upload by BBC Archive

Be sure to check out 3:59 on. I won't give it away, but it's interesting they had the same views back then. Note 7:33 for a glimpse of what would come. Finally also see this post for Daphne Oram's Oramics and her Bird of Parallax. See the Oramics label for more.

"What is electronic music? How is it produced?

Desmond Briscoe - the head of the BBC Radiophonic Workshop - enlists the help of Daphne Oram, David Cain and John Baker to explain the fundamentals of synthesised sound.

This clip is from Workshop: The Same Trade As Mozart, originally broadcast 3 August, 1969.

You have now entered the BBC Archive, a time machine that will transport you back to the golden age of tv to educate, entertain and enlighten you with classic tv clips from the BBC vaults."

Doobie Rhythmini FR-112 preset rhythm drum machine

video upload by Harry Axten

Note this is the first post to feature Doobie and the Rhythmini. If you know more about either, feel free to leave a comment at the bottom of this post.

"Thought I'd record a brief demo of what this somewhat rare machine sounds like prior to selling it - not that it's anything particularly special. It's based around the Sanyo LM8972, so will have the same patterns as every other rhythm machine that uses this IC.

Not much known about the company other than it was made in Japan, presumably in the late 1970s. Possibly related to the Newport Rhythm Sound, which looks visually similar."

Lyre Inc. FDSS Studio Additive Synthesizer + Resynthesis

via this auction

This is the first post to feature both Lyre inc. and the FDSS Studio Additive Synthesizer. It was spotted and sent in via M Me. The listing, images, and info is from, posted here with permission.

Details from the listing:

"I am offering my ultra mega rare Lyre FDSS Studio.

The FDSS is an additive synthesizer with analysis and resynthesis function from 1987

The technical data is on the last picture in the web, you can find almost nothing about it

Ultra rare , as far as I know less than 50 devices have been built , only three have been delivered to Europe .

This synthesizer was available as an 8 or 16 voice version,
The 8-voice version was always the basic version, which could be expanded to include a further 8 voices out of 16.

Like the famous Technos Acxel synthesizer, the Lyre
FDSS synthesizer also designed and built in Quebec / Canada.

You had to operate it via a terminal, similar to the

Synclavier, Synergy or Kurzweil K150FS.

Software was and is included for PC and Apple Mac

Mac could be connected directly and with the PC you needed a card (ISA is included)

price, no idea.....

with such rare things "whatever someone is willing to pay" applies :-))

or exchange for vintage synthesizer?"

Skyline Pioanotronic 61

via this auction

Controls for Tune, Bass, Pianos, Piano, Clavichord, Timbre, Phase, Phase Rate, Phase Reactance, Output Level..

"If you've never heard one, here's a nice description: 'piano sounds like a square wave mixed with a sawtooth, the clavichord is a pulse wave, and the bass is a square wave, very short and percussive and electronic sounding. Best sound....piano mixed with clav with phase on - instant Kraftwerk,'"

Note this is the first post to feature the Pioanotronic 61.

National KX-33 Panakit

via this auction

Another one spotted by M Me.

Note the only ins and outs are on the front panel. It appears to be some sort of drum machine sequencer. If you know and/or can translate the controls, let us know in the comments below.

National (Panasonic) also made the RF-1300 and SY-50 Rhythm Machines as seen in previous posts.

Update: See the comments at the bottom of this post for more.

The Surprising Musicality of a Telephone Line Simulator

video upload by HAINBACH

You can find the post HAINBACH mentions with pics here.

"Of all the instruments in my studio filled with many obscure things, this is the one that draws most peoples attention: the vintage telephone line simulator by Axel Electronics. It looks rather disco for a piece of test equipment, with its Battlestar Galactica golden color. In this video I put it through its many surprising musical applications.

via this auction

"This is by far one of the rarest synthesizers ever built! only 5 left and 1 is known to be working!

there is a high possibility that this system belonged to tangerine dream!

you will never ever have a chance to buy it again unless you decide to get it now! it works and loads all the software."

Creation Modular Systems - Red 909 & 808 Red Rack Based Modular Drum System

via @KleineMusic, via @emptyvesselnz

"Anyone know anything about this? a modular drum unit with all analogue versions of the TR909 Bass/Snare/Clap/HH and a TR808 Bass/Snare....."

Modules from left to right:

TR-909 BASS ms-9 w/ Level, Tune, Attack, and Decay knobs
TR-909 SNARE ms-9 w/ Lvel, Tune, Snap, and Tone knobs
TR-909 CLAP ms-9 w/ Level knob
TR-909 HiHAT ms-6 w/ Level, Tune, OH Decay, and CH knobs
TR-808 BASS ms-8 w/ Level, Tone, and Decay knobs
TR-808 SNARE ms-8 w/ Level, Tone, and Snappy knobs
PROFESSIONAL DRUM - SYSTEM - modular systems - blank panel
PROFESSIONAL DRUM - SYSTEM control panel with Limited logo, MAIN volume knob, ON switch, an additional knob with button, three TRIGGER LEDs w/ buttons, and a small display with an additional button.

It's interesting that the TR-909 HiHat has a ms-6 label rather than ms-9.

Note there are no patch points. It almost looks like a Clavia (Nord) prototype rack drum system. It does appear to be 3U high like eurorack. Could be a nicely done DIY system.

This appears to be the first post to feature Modular Systems on the site. If anyone knows anything about them, let us know! Thanks to @emptyvesselnz for bringing this to our attention. Whenever I think I've captured it all after 15 years of running the site, something new old pops up. See the New Old label below for more.

Update: two new pics in via @KleineMusic. You can see the brand name on back is Creation Modular Systems. You can see individual outs, main stereo outs, MIDI In, Thru, Thru-1, Thru-2, and 3 trigger outs, and AC 230 V socket on back.
