Oberheim OB-X8, a monster roars at Superbooth

video upload by Hispasonic

"The first instrument from the reborn Oberheim is a monster for a variety of reasons: for its size and price, of course, but above all for the heritage it carries inside, condensing the sound of four great synths: OB-X, OB-XA, OB-8 and OB-SX, covering a golden era spanning from 1979 to 1983.

We had the chance to try it out at Superbooth with Gerry Bassermann, who introduced us to its classic sound engine, its new keyboard, its filters and oscillators, and the mythical 'page 2' secrets."

Sequential Prophet-6 Sound Bank '79

video upload by Polydata

"Drawing from the earliest days of polyphonic synthesizers, Sound Bank ‘79 for the Sequential Prophet-6 finds its inspiration in synthesizer music found in documentaries and library music from the late 70’s and early 80’s.

A simple set of 30 patches for instant inspiration. Sound Bank '79 will be a series for different synths and plug-ins, so look out for future releases.


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.

1985 Roland Juno 106 (Serviced) SN 539586

via this auction

Additional SYNTH CITY Listings

"A high water mark for glassine pads, premier brass stabs, and surprisingly present basses, the Roland Juno 106 is well deserving of it's status as a classic synthesizer. All voices have been refurbished, this is a fully working specimen, with all sliders and pots cleaned and working wonderfully. Physically, this is a synth which shows it's age and use, but operationally this Juno is a superior sonic experience.

This Juno was just serviced by our in-house technician, all voice chips have been refurbished, all new tact switches and power supply has been fully recapped.

Serial number: 539586"

Waldorf Microwave XT - Non Nextel - Mint with New Knobs

via this auction

"This is the rare Non-Nextel edition and in really good shapoe.
There are not a lot of Non-Nextels around there and actually this is the only edition who doesnt get shitty colors.
Hence the price. It's also a V3 board so it can receive the voice upgrade which is still available around.

Whats the difference with the Nextel versions? Most Microwave XT versions have that that terrible Nextel paint which decays (gets sticky, flaky, dirty and grey-ish) over time and this can't be fixed. The surface on the edition listed keeps the strong orange colour. I will add some pictures in daylight this was at dawn. Also this version hold it's value if you look at the website history it sells for around this price.

Also the synths had really terrible knobs which are decaying and get sticky and just break apart. I replaced them with premium knobs who look better and don't fall apart over time.

The unit is close to mint it has a few scratch from it's age :)
Display is perfect
Latest version produced so comes with Board #3, possible to upgrade to 30 voices
Original Adapter included"

ADDAC System | ADDAC403 VC Time Signature Clock Sources

video upload by DANIELE

"ADDAC403 by ADDAC System: 8 independent trigger outputs and an easy way to incorporate standard time signatures in your eurorack modular system, along with the possibility to generate syncopation, irregular tempo ratios and phasing, all at once!

0:00 Intro
0:59 Beats output, beats p/bar and beat unit
1:26 Bars output and even output
1:45 Odds output
2:07 Divider section
2:59 Swing delay section
4:03 Phasin section
4:50 Tuplets section
5:44 7/4 Time signature
6:18 More functions"

"This is our long due Eurorack Clock module, featuring multiple sections for a combined total of 8 independent trigger outputs.

Introducing standard time signature musical notation along with the possibility to generate syncopation, irregular tempo ratios and phasing all at once in a single straight forward unit.

We started by programming an extremely stable digital clock with over time drift compensation and adjustable to any Beat per Minute [BPM] up to 1 decimal case (from 0.1 to 250.0 BPM). Also implemented a Tap Tempo button and Pingable input for syncing to external clocks using either Soft or Hard [SYNC] modes.

The Time Signature X/Y section defined as [Beats Per Bar] / [Beat Unit] and generating 4 outputs triggering at every: Beat, Bar, Odd Beat (1,3,5...) and Even Beat (2,4,6...).

A [PAUSE] button sets the Pause/Resume state of the clock also allowing different sync methods on Resume.

A [RESET] button resets either each or both the Main and Phasing Clocks

A Divider section can be set to any beat division in Linear (3,4,5,6,7,8,9,10) or Exponential mode (1,2,4,8,16,32,64,128)

The Phasing section features a totally independent clock that can run in two modes:
[TEMPO] running at a slower/faster bpm phasing in and out of tempo against the main clock.
[OFFSET] running at the same bpm but offsetted/delayed against the main clock generating a steady syncopated beat.

A Tuplet section allows the generation of Triplets, Quintuplets, Septuplets and Ninelets with adjustable [LENGTH] or Span of the tuplet to any number of Beats from 1 to 16.

4 Modes allow different [TRIGGER] and [MUTE] functionalities: they can run in a loop or one shot mode, [TRIGGER] always triggers/resets the Tuplet and [MUTE] can be set to Gate On or Gate Off. Tuplets always output irregular divisions of the Beat and allow Polybeat generation.

A Swing Delay section allow to delay 1 Beat at [Every X Beats]. The [Delay] knob sets the delay in a fraction of 1 Beat, this section also allows the generation of syncopated beats.

More specific settings can be changed in the [SHOW/MENU], menu functions are labeled in gold.

All sections feature they’re own monitor LEDs.

By default Display shows the current Time Signature status.
Pressing the [SHOW/MENU] button sequentially will display each sections settings.
After 3 seconds it automatically returns to default Time Signature status.

All settings can be saved to a single memory slot, upon startup the memory state will be automatically loaded.

All Knobs and Push-Buttons have their own CV/Trigger inputs except the [BPM] encoder and [SHOW/MENU] button."

Eurorack Module In A 5U Modular

video upload by John L Rice

"It's nothing really new, people have made these for themselves in the past, some companies have made short runs of medium sized ones, and has a couple large ones they currently sell, but I can't mention the company who made this one or any details about it, at least for now.

The eurorack module in the 5U mount is a micro Braids built by which is an 8 hp version of the original Braids by Mutable Instruments. I reviewed this system in my first breakdown video which you can watch to learn the details: [posted here] As it is now it's "old school analog" on top and "new school digital" on the bottom! ;-)"

morphagene, beads, arbhar | eurorack ambient | unexpected dream

video upload by patchesinblue

"'unexpected dream'

this might just be the shortest Eurorack ambient video here on YouTube.

a combination of textures from the mutable Instruments beads, the make noise morphagene and the instruo arbhar with rings playing a melodic line in a lower register

just like a dream that appears out of nowhere and then disappears just as vaguely, this piece is an abbreviation of a longer piece that i can't remember having either a tangible beginning or a decisive end

Befaco AC/DC, interfaz de audio Eurorack

video upload by Hispasonic

"Befaco estuvo un año más presente en la Superbooth de Berlín, esta vez con una propuesta mucho menos analógica que de costumbre: AC/DC, una interfaz de audio acoplada en continua, en formato Eurorack.

AC/DC se basa en la plataforma OWL de Rebel Technology, y aquí reside probablemente su mayor atractivo. Permite enviar y recibir tanto CV como audio a 16 bits/48 KHz, así como cargar patches de la librería de Rebel. Es compatible con los DAW y generadores de CV más populares, y también sirve como procesador de audio/CV para aplicaciones iOS."


"Befaco was once again present at the Berlin Superbooth, this time with a much less analog proposal than usual: AC/DC, a continuously coupled audio interface in Eurorack format.

AC/DC is based on Rebel Technology's OWL platform, and this is probably its biggest draw. It allows you to send and receive both CV and 16-bit/48KHz audio, as well as load patches from the Rebel library. It is compatible with most popular DAWs and CV generators, and also serves as an audio/CV processor for iOS apps."

Tesseract, módulos Eurorack desde Sevilla

video upload by Hispasonic

"Mangu Díaz es un sevillano enfrascado en una miríada de proyectos musicales. Entre ellos está Tesseract, su propia marca Eurorack, cuya lista de módulos anda ya por la veintena.

En este vídeo nos explica detalladamente el funcionamiento de Tukra, un secuenciador de 8 pistas con audio y midi que promete ser "una solución todo en uno para la batería en tu rack" y además, tiene una gran capacidad de integración con otros equipos (no sólo Eurorack). En Tukra no hay submenús, todas las funciones y vistas son accesibles en todo momento, y ofrece hasta 64 pasos por patrón, 64 patrones, 64 partes y 16 canciones por proyecto.

También nos muestra su última creación, Step Fader MkII, que estará disponible este mismo año. Como su nombre indica, es la evolución del anterior Step Fader, un secuenciador dual que presume de ser divertido de usar.

"I recently got a second 258T oscillator, all the way from Australia because they seem to be sold out anywhere else. Why? Because most Buchla designs feature a quad 'whatever' design and the 258T is 'only' dual. I could imagine a second one would open a lot more possibilities. And it did! I hope you'll have as much fun watching this video as I have working with these amazingly affordable little masterpieces. Thank you, TipTop & Buchla for bringing this to a wide audience!"

Edmund Eagan is using a Continuum Slim 70 and a Eurorack set including the Eagan Matrix module, connected to the new single body Pyramid from La Voix du luthier.
The recording was done on an iPhone and kindly shared by Antonio Machado (the audio is also from the iPhone and a bit noisy due the the environment, but also preserve the acoustic side of the performance)
The concert was mostly improvised. This is a 16 minute except of a 45 minutes performance."
