SYNTH-WERK Introduces SW 1630 BODE FREQUENCY SHIFTER & SW 735 Rack Version



via SYNTH-WERK

"After long and intensive research & development work we are very proud to announce our newest creation, the SW 1630 & 735 BODE FREQUENCY SHIFTER. The first batch of 10 units is already build and sold to our friends from the waiting list.

From today on the Module is available and can be ordered.

Price:

SW 1630 BODE FREQUENCY SHIFTER : 1.950 Euro + TAX
SW 735 rack version: 2.150 Euro plus TAX"

FUNCTION DESCRIPTION
A frequency shifter is an audio signal modifier which shifts the entire frequency spectrum of the applied signal by a given amount. The Model SW 1630 Bode Frequency Shifter allows the amount of shift to be accurately and continuously controlled over a span of -5000 Hz to +5000 Hz, utilizing voltage and/or manual control. The relationship between the control voltage sum and the amount of shift may be either linear or exponential. Up-shifted and down-shifted outputs, as well as a continuously variable mixture of the two, are available simultaneously and independently. Variable threshold squelch and zeroadjust fine tuning controls are provided.

The Model SW 1630 Bode Frequency Shifter changes the ratios between the frequency components of an audio spectrum, thus producing a variety of novel sound quality transformations. Applications include a wide variety of tone color modification, P.A. feedback suppression, linear frequency modulation, novel tape feedback effects, and the generation of dynamically varying clangorous tones.

MUSICAL APPLICATION
In shifting the components of the input audio spectrum by a given amount, the SW 1630 Bode Frequency Shifter changes the original ratios between the overtones and other frequency components of the input signal. Rather than being a transposing device, this instrument is a means for achieving an extremely wide variety of tone color modification. Whether the amount of frequency shift is large or small, static or time varying, or whether the input signal is simple or complex, the processed outputs will generally be musically interesting."

Moog Bode Frequency Shifter model 6552 Owned by Walter Sear


via this auction

"This auction is for a super-rare rack mount Bode Frequency Shifter Model 6552 by R.A Moog. This is from the personal collection of Phil Cirocco of CMS / Discrete Synthesizers. This is a once in a lifetime opportunity to own a rare piece of electronic music history.

This is serial #1001 and is the very first Frequency Shifter produced by R.A. MOOG. This particular 6552 was once owned by the great Walter Sear. It features ring modulator diodes that were hand selected by Harold Bode himself! It is listed in the Moog Archives http://moogarchives.com/ on the left menu select: "lists and charts", then: "custom sales" then: "frequency shifter".

There were 2 major incarnations of frequency shifters made by Moog/Bode. The first one (model 6552) is the one you see here. It is all discrete and uses actual diode rings and transformers for its ring modulator circuits. The second version (model 1630) is an op-amp chip version that uses balanced modulator ICs for its RM circuits. The second version, while being more convenient, does not sound anything like the first version.

I can say with confidence that you will never see one of these for sale again in your lifetime.

This Frequency Shifter is in excellent condition. There are no scratches on the front panel. It is #1 out of a known total of 11 units made. It was made by R.A. Moog under contract with Harold Bode. It is all original and functions perfectly. It is NOT a clone and it has a valid serial number and pedigree. It was recently calibrated here at CMS. It uses terminal strips in the back as all early Bode rack mount units do, so you will have to use a patch-bay nearby."


This one in via Keld.

Update via Michelle Moog-Koussa: I heard from Michelle Moog-Koussa, Bob Moog's daughter and Executive Directory of The Bog Moog Foundation. She stated, "I'm 99% sure that the model number and serial number are written in Dad's handwriting.

This piece was issued on August 21, 1968. Thirty-seven years later to the day the frequency of the whole electronic music community would shift as Bob's body left us......."

360 Systems 20/20 Frequency Shifter (BODE)

via this auction

"This is a very rare item, probably the first I've seen one on ebay. It is a Frequency Shifter, model 20/20 by 360 Systems.

360 Systems was (and still is) an innovative company that developed this pitch changer (as used by Synergy/Larry Fast, John McLaughlin), one of the first guitar synths (John McLaughlin) the first sample-playback keyboard and many audio post devices since. They also developed the first LINN Drum for Roger Linn. Bob Easton was/is their clever designer."
360 based their design on Harold Bode's rare "Klangumwandler" that was made and sold for Moog in the late 1960s and early '70s.

The Moog/Bode 6552 Klangumwandler ('sound-changer', in German) was an interesting concept, to modify pitch (frequency) without changing the overtone structure. Bode's invention was first created for Ussachevsky's electronic music studio at Columbia University (Bob was quite familiar with the composer and studio, as well as his various students like Wendy Carlos. Wendy and Tomita used this module on their classic albums. Club of the Knobs synthesizers now make a very accurate replica of the original Bode/Moog module and you can see it (and the similarity to this 360 design) on their website. The 360 has the same "series of 5" settings (5,50,500) as the Bode - and mixed vs. independent outputs, although the squelch is internal on the 360 via trimpot. There is CV (Voltage Control) of the frequency - great with a sequencer, CV pedal (McLaughlin) or random. These are similar to a ring modulator, but have a VERY unusual effect at the lowest settings. This is the effect I love (and why anyone should own this) - a deep phasing in stereo, without "messing up" the sonic quality of the original signal - all bass a treble frequencies remain solid, and the harmonics shift around in stereo beautifully. It's weird but not ugly - very HiFi and cool-sounding.

BODE

some text from the web):
'... the EWE, which stands for Electro Wagnerian Emancipator. There's only one of them; it was designed for me by Bob Easton at 360 Systems… That is now gathering dust in the warehouse. I tried to use it on "Big Swifty" from Waka/Jawaka - Hot Rats, but it didn't end up on the final track." (BTW synth geeks - this is mystery item was basically just an EML Polybox, same idea!)

'We also have some neat little 360 Systems model 2800 programmable equalizers, which are four-band parametric with memory storage for saving any particular settings that you may like. Those were designed by Bob Easton and are no longer available, but we have a few of them.'"

via Brian Kehew of Moog Cookbook

Update via eben in the comments: "check out the comment in that ebay auction in the questions section - none other than Tom Rhea, author of the minimoog owners manual"

via the auction:
Q: Hey neighbor, interesting that you have a frequency shifter for sale, but your description that a klangumwandler shifts without changing the overtone structure is incorrect. Pitch shifting a la the Eventide Harmonizer does this; Harald Bode built frequency shifter(s) that provide a LINEAR shift in frequency (Hz) for all partials in the input signal. This will, of course drastically change the "overtone structure," not preserve it. Sorry to be a drudge about this, but I knew Harald well, teach this stuff at a well known music College," This message purely in the interest of sharing information. Hope you get a good penny. PS, I have several Bode 1630 FS (lucky me, but just knowing Harald was the real treat!) Tom Rhea (author Minimoog Owner's Manual, etc.) Good luck in the sale! Apr-14-09
A: Hey Tom - you are likely QUITE right. I only said it was based upon the Bode - which seems quite true given the controls and front panel, steps of "5's" etc. Obviously, the audio track given shows what this very unit does exactly, so no deception is implied.

BSF-1 - Virtual Bode Frequency Shifter

"The BFS-1 is a VST emulation of the famous Bode frequency shifter.

The original unit was available as an expensive module for the Moog™ modular system.
Now you can get this special sound into your PC for a reasonable price.

The frequency shifter is not a pitch shifter, which changes frequencies by a multiplikation. Instead it shifts all frequencies/harmonics by adding a fixed amount. The sound reminds to a ring modulator, but unlike this, it is possible to get the upshifted and downshifted signal seperately.

Unlike a ring modulator, the frequency shifter is also capable of changing the signal by a low amount, e.g. 1 Hz, to obtain effects known as “Barberpole flanging”.

This plugin has some additional features like delays for each section, an LFO (all host synced), an envelope with MIDI trigger and an envelope follower to modulate shift and/or volume."

Bode Frequency Shifter cased & psu

via VEMIA

"Moog / Bode Frequency Shifter 1630 The Bode Frequency Shifter was originally designed for use with Moog modular systems. The sound of the Bode is unique – it produces highly complex waveforms by shifting not only the fundamental but all input frequencies by the same amount. The result: non-harmonic relationships between the frequencies in the output signal. This particular one comes in a nice wooden cabinet with a power supply (230 V), just as it was mounted and sold by Studio Funk Hamburg in the early seventies. Of course it can still easily be built into a modular system. The machine has been checked by a tech recently and is technically in a very good condition. The wooden cabinet shows minor signs of usage. A copy of the original (unfortunately not complete) description by Studio Funk in German language and some notes from the moog modular systems owner’s manual on the Bode are included as well."

Original Instructions & Demo Tape for MOOG Bode Frequency Shifter

Note: Auction links are affiliate links for which the site may be compensated. via this auction
via the seller: "Up for bids is a set of both Original Short Form Operating Instructions and a Demo Tape for the MOOG Bode Frequency Shifter Model #735. I used to have this modular part as part of my modular system which I bought in the late 1970's and sold several months ago. I recently found these 2 items. I'm sure that someone will find them of great interest, since this was one of the rarest Moog modules ever produced.

The instructions appear to have come directly from the Bode Sound Company, and are on their letterhead. They are the original typed instructions, and not photocopied. These instructions are two full typed pages, and a 3rd page , which is a diagram, as you can see in my pictures. (there is also a hand drawn diagram on the back page- not drawn by me)

The tape is a regular cassette tape. There is a label on the tape itself- Side A states: Demo of Bode Vocorder Model No. 7702. Side B states on the label- Demo of Bode Frequency Shifter Model 735. The cassette is checked Dolby. Please note: I have never listened to this tape (although looking back I don't know why I didn't). It was included when I bought the module many years ago. I cannot guarantee what is actually on the tape, but I have no reason to presume that it is anything other than what the label states. The tape looks to be in good condition, with no hang-ups (turns freely), but for the reasons stated above I cannot guarantee that it works, and I don't have a cassette player on which to test it. Remember.....it is 35 years old!!! So I am offering it as is, and including it with the Instructions, which I am sure will be quite interesting to you."

Bode 735 Frequency Shifter & Electronic Specifications

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

via this auction

"For auction is an extremely rare Bode 735 Frequency Shifter. This is a device designed by Harold Bode in the 60’s which was produced until the early 80s by his company Bode Sound Co.
This instrument is most well known for being repackaged and included as the Moog 1630 Frequency Shifter of the 1970s Moog Modular systems.

The Bode up for sale has been dated to 1972 and appears to use the same PCBs as the Moog 1630. These were hand assembled by Bode and are extremely uncommon outside university electronics studios.
I acquired this one in 2002 and was told at the time it once belonged to Vladimir Ussachevsky who started the Columbia Princeton Electronic Music Studio in the 1960’s.

CONDITION:

I have been collecting and repairing vintage electronics since the 1990’s, I have over 18 years experience as a restoration technician of high end and rare instruments and this is from my personal collection.
There has been no work performed on this historic device besides replacing the frayed power cable for safety reasons, the old cable will be included in the sale if the winner wants it. I found the identical vintage
style cable at an electronics supplier to keep this as authentic as possible.

There are no unexpected surprises here."

Harold Bode's Birthday & the Bode Ring Modulator Schematics

via The Bob Moog Foundation

"It’s the birthday of Harald Bode (1909-1987), German-born pioneer in synthesizer design and inventor of the Warbo Formant Organ (one of the earliest polyphonic synths), the Melochord, and the Bode Frequency Shifter, among many other instruments and devices.

Bode and Bob Moog began to work together in 1966, and this ring modulator is an indication of their partnership. Bode’s Ring Modulator and Frequency Shifter designs were implemented in R.A. Moog Co. products, and his vocoder was the basis for the Moog Vocoder released in the 1970s.

The schematic below was hand-drawn by Bob Moog himself. (Note the the “B.S.” in the “drawn by” square. In order to keep from having his initials in all the boxes when he drew up a certain schematic, Bob would use joke initials B.S.) Image: Bob Moog Foundation schematic for the Bode Ring Modulator. Many more Bob Moog Foundation archival schematics here: http://moogfoundation.org/schematics/"

"Warbo Formant Organ (1937), an archetype of today's polyphonic synthesizer, was a four voice key-assignment keyboard with two formant filters and dynamic envelope controller. Eventually it went into commercial production by a factory in Dachau, and it became one of the earliest polyphonic synthesizer products, along with Novachord (1939) by Hammond.

Melochord (1947–1949) developed by Bode was extensively used by Werner Meyer-Eppler in early days of the electronic studio at Bonn University. Then in 1953 a Melochord, along with Monochord by Freidrich Trautwein, was specially commissioned by the Studio for Electronic Music of the Westdeutscher Rundfunk (WDR Studio in Cologne, West German Broadcasting Corporation), and used by the Elektronische Musik group throughout the 1950s. (See #Melochord at the WDR Studio in Cologne for details)

From 1950, Bode designed electronic organs for the Apparatewerk Bayern (AWB) in Germany and the Estey Organ Company in the United States. In 1954, Bode immigrated to the United States as a chief engineer (later vice-president) of Estey Organ, and resumed his research at several companies and as a contractor of German companies.

In 1959-1960, Bode developed modular synthesizer and sound processor, and in 1961, he wrote a paper exploring the advantages of newly emerging transistor technology over older vacuum tube devices; also he served as AES session chairman on music and electronic for the fall conventions in 1962 and 1964; after then, his ideas were adopted by Robert Moog, Donald Buchla and others.

After retiring from the chief engineer of Bell Aerospace in 1974, he composed TV-advertising spots and gave live concerts. Also in 1977, Harald was invited as a chief engineer of the Norlin/Moog Music after Robert Moog left.

He died in New York, New York, United States in 1987."

Analogue Systems RS-240 Frequency Shifter Demo


YouTube Uploaded by pjoris2 on Aug 7, 2011

"A quick demo of the Analogue Systems RS-240 Frequency Shifter I bought a month ago and just managed to connect in my eurorack modular. Every sound in the video, apart from the delay, is made with Analogue Systems modules -- still hoping for that sponsoring contract ....

The demo starts with a basic patch of 2 RS-95 oscillators (pitch controlled by the AS Sorceror keyboard), through an RS-165 signal mixer in the RS-110 multimode filter. The lowpass output of the filter then goes in the RS-180 VCA. The VCA and the filter cut-off are both controlled by an RS-60 envelope generator, which is triggered by the clock output of the RS-200 sequential controller. In addition to the envelope output, the filter cutoff is also controlled by the triangle output of an RS-80 VC-LFO. For this the envelope and LFO output are combined in a RS-160 control mixer. The first minute of the video give this untreated sequence. I try pointing out the patch cords and signal path.

After this I plug the output from the VCA in the RS-240 Frequency Shifter. The A (downward shifted signal) and B (upward shifted signal) outputs are send to two channels of my mixer panned hard left and right. The frequency shift is modulated by the output from the RS-200 sequential controller -- so giving a different shift for each step -- and the triangle output from a second RS-80 VC-LFO.

I show the different sounds resulting from varying:
(a) the scale of the RS-240, this switch controls the amount of maximally possible shift from 0 to 5000Hz;
(b) the amount of sweep from the LFO (by varying the output level of the LFO);
(c) the amount of variation from the sequencer (by varying the range of the output of channel A of the sequencer).

After a few minutes I add some delay (courtesy of an Ibanez DM1000 early 80s digital delay) of the mixed output of the RS-240 to give further variation.

This is my first patch with the RS-240 (Bode) Frequency Shifter, but I like the sounds coming from this and there are few demos of this module on the internet so I hope you will enjoy it too."

Club of the Knobs - COTK Bode Frequency Shifter - Moog 1630 Bode Shifter Clone SN 2538

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

via this auction

"This is a used Club of the Knobs - COTK - C1630. A clone of the Moog 1630 Bode Frequency Shifter. A really stunning module that has all the behavior, quirks, and richness of the original. I just want the rack space for other modules, like a COTK envelope follower, and a couple of others I'm thinking about :)

This is used. Built in November 2013, delivered in January or February of 2014. Serial number C 2538. It consumes 3U in width and is a full height module compatible with any Moog style cabinet format.

I've been using it with a Synthesizers.com QPS5 power supply (inside is a Power One linear supply) connected to a COTK power distribution strip. I've had no problems with this setup, but you will need to provide proper power for the module. See the COTK web site for technical details.

There is no "manual", but moogarchives.com has the instruction page from the original Moog manual.

You will get what you see in the photos:

The module;
The power cable; and
Three spare lamps.

The lamps aren't hard to find. You can get them in bulk from Mouser, singles from Synthesizers.com. I just think it's handy to have a couple of spares...

The last I checked, 5/5/2018, the new price was 970 Euros, about $1100.00 - $1200.00 USD, see COTK web site for pricing."

Surrey Spectrum Frequency Shifter

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

via this auction

This is the first Surrey post. Via the listing:

"This is something special and quite unique.. The Spectrum Shifter by Surrey Electronics. Rare audio processing device from the 70-ties, not the same principle as a pitch shifter. A bit like a budget Bode shifter. The slider might need some cleaning but everything works and it is ready to play or mod into...

Please have a look at the pictures and see for yourself. Let me know if you have any questions. Please check my 100% positive, music/synth/studio related feedback. I'm a serious and professional seller AND packer.

Something about frequency shifters from the web:


'a frequency shifter will shift all frequencies additively. Thus, the spectra (overtone content) of the source will become increasingly distorted with shifting. This is opposed to say, a Harmonizer's pitch shifting. Frequency Shifters usually use a quadrature oscillator as the carrier (these were usually voltage-controlled in analog synth oriented models), and at low rates, can be used to reduce microphone feedback. The famous devices designed by Harold Bode can shift up to 5k and good carrier rejection, and were used in electronic music studios to radically alter sounds, especially sources with a lot of noise, such as percussion. FS's were featured in several analog synths, such as the Buchla, Serge (two versions, one with external carrier), and the Moog (licensed from Bode).'"

Update: some info on the module via https://synthtech.com:


"INTRODUCING THE E520 HYPERION, A STEREO EFFECTS PROCESSOR

Kickstarter campaign launches on Nov. 15th and the KS page will activate on Nov. 10th. Estimated shipping: late May 2020.

OVERVIEW

The E520 Hyperion is a mono/stereo in, stereo out effects module. It is 48HP wide and uses less than 300ma of +12V and less than 70ma of -12V.

Powered by a 480MHz ARM Cortex M7 CPU, the E520 has 64MB on on-board SDRAM for recording up to 6min of stereo audio at 48KHz sample rate. The LCD screen and optical encoder navigation uses the same 'shallow' menu scheme of our E352 and E370 modules, with the addition of 4 'soft keys' for selecting options without having to leave the main page.

The E520 uses a premium audio path not usually found in Eurorack. Crystal Semi CODECs, TI OPA-series op amps and WIMA film caps in the output stage are used along with low-noise, dedicated LDO voltage regulators for a clean, full soundstage. Audio conversion uses 48KHz sample rate, 24bit resolution with a line or synth level setting.

Please note this is a 'living document' and subject to modification at any time over the next 8 weeks.
