Overpriced Pair of 1970s Urei 565T "Little Dipper" Filter Set

Note: Auction links are affiliate links for which the site may be compensated.

via this auction

"This listing is for a pair of gold-trimmed Urei 565T Filter Sets in a black Tolex case (or without). These look incredible. The seller we bought them from wrote:

The 565T offers precise notching and peaking of very narrow frequency bands. The major application is to remove unwanted noises from recordings. Used extensively by the movie industry. It can also be used to create flanging, phasing and other unusual effects.

The 565T has an output transformer that can send a balanced signal to a 600 ohm load. The input level can be switched up 20db and the input impedence can be set between 600 and 10K ohms. This item came out of temperature controled editing suite. The suite had preventative maintenance done quarterly.

Having these will make you feel better in your studio, and feel better about your studio.

You don’t need to worry about the rear connections. You don’t need to make pigtails. You have an in and an out right on the front of the unit, and it takes balanced TRS or unbalanced TS.

What will you use it for? A notch filter, feedback murderer? Lowpass filtration on the 2bus for performative transitions? Nasal peaks? Dub stuff? Purist period-correct cinematic effects? Reductive sonic biopsies, additive implants?

Atomizing Acoustic Drums With Nuclear Research Equipment | Loop Pack

video upload by HAINBACH

"I wanted to spend time with an old friend of mine, who happens to be an excellent drummer. So I posed an experiment for us: what happens if you run acoustic drums into vintage nuclear research instruments? Spoiler: it sounds devastating! We liked the result so much that we made it into a 'Nuclear Drum Loops' pack, complete with single samples. Its ideal in any genre where you want something rough and different for your drums. Available now on"

Watford Electronics Rhythm Generator

Note: Auction links are affiliate links for which the site may be compensated.

via this auction

This one was spotted and sent in via M Me.

This appears to be the first post to feature the Rhythm Generator. Watford also made a Mark 1 drum machine mentioend in RHYTHM MACHINES - The Rise And Fall Of the Presets - by Alex Graham.

Details from the listing on the Rhythm Generator:

"Vintage Watford Electronics Rhythm Generator 1970s Drum Beats Machine Rare.

Built as a kit from Watford electronics parts with the UK magazine practical wireless. Basic unit but it's pretty rare. The exterior case is a little marked, the maker appears to have used it as a soldering iron rest 🤦🏻‍♀️ Would probably benefit from power and output leads / plug being rewired replaced, but it's been tested as working as far as using a pair of headphones goes with it. All the beats were heard through them and tempo/ volume change etc."

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."

How Ancient Electronics Write Music For HAINBACH

video upload by HAINBACH

"I was commissioned to write a piece for solo sax and electronics, something I have never done before. I decided I would approach the composition in the same way that I improvise with other musicians. I would compose as if I was on stage with the performer, Dr. Hall. The 'live' setup I created for this ended up writing a good part of the music for me, in a human/machine feedback loop.

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.

HAINBACH Built An Early Electronic Music Studio In His Basement

video upload by HAINBACH

"Inspired by German experimental music studios like the WDR and SWR, I build Studio B (B for basement). It is a creative playground for my "Schlaufenzeit" setup, and I am working on a live show and album there. In this video I go into details on the gear and thought process behind its, how I put everything together and the big challenge using the cellar poses. I hope this video inspires in your own music studio setup, be it big or small, or 100% DAW.

AudioThing Dials - The Massive Sound Of Vintage Test Equipment

video upload by HAINBACH

"You all have been asking me about making a test equipment based filter plugin, and now its here! Together with @AudioThing I developed DIALS, an experimental channel strip. Based on a classic American passive band-pass filter and a modified German broadcast transmitter, DIALS brings you the massive sound of test equipment music in plugin form. Whether you want to mangle signals in broad strokes or finely sift through frequencies, DIALS has you covered. If you desire to tread further, it becomes an instrument unlike anything else.

INTRO PRICE: 49$/€ REGULAR 79$/€ (offer good until end of October)

"Take a trip to the outer reaches of music production with the Hainbach Bundle. LoFi radiations from a Cold War wire recorder, the rotating madness of the Radiophonic Workshop, metallic resonances from 1930s France, Stockhausen-esque feedbacks, or a trip through Noise in all its forms, the Hainpack is as steeped in history as its full of modern music tools."

Playing Live With The Dream Collection At Willem Twee

video upload by HAINBACH

"After my first visit at Willem Twee Studios in Den Bosch I knew I had to come back. And I did, this time for a live gig at the Toonzaal. Rikkert had the idea I had secretly hoped for - to involve the studio in the live show. So I setup a patch, to which Hans Kulk and Rikkert Book added beautiful tape processing and effects.

Making Music With a Swiss Power Grid Messenger

"In which I use a Landis & Gyr Rundsteuerung transmitter to make music. Originally, this was meant to transmit commands over the power grid. Applications were manifold, but always custom engineered: control grid strength, set street lights, railway control or even as an alert for the fire department.

Early Electronic Music Techniques Explained #superbooth22

video upload by HAINBACH

"I was asked by Goethe Institut Tokyo and Gebrüder Teichmann to do a talk on early electronic music techniques, with a special focus on Stockhausen and the WDR. I had no idea how I could present the results of my research in a fun way until the morning it was due, when a friend asked me to connect the dots of what I was doing. What a better way then to create a piece, like I do on my channel anyway? Using techniques by Stockhausen and others at the WDR Studio, I assembled a piece with audience help in an 'Against The Clock' fashion.
I held this talk at Superbooth22, thanks to everyone at the stage, sound, light and film crew for making this recording.
