Muscarin Synthesizer demo (playing only)

Published on Apr 16, 2020 Phaneronaut

Since recording this video I've released a whole album built around the Muscarin. You can get it for free at https://phaneronaut.bandcamp.com/albu... But beware, it's strange.

This is a kind of demo of the new(ish) Muscarin drone and noise synthesizer by kNoB technology. I tried to feature some of the functionality of the synth in the improvisation. But as I only got this a day ago, I haven't explored the machine even close to fully, in fact there are some parts of the architecture that I don't quite understand yet."

"You may know or not know this one. This is the rare Muscarin by Knob Technology.
Crazy experimental synth. Great condition.

You can rack it or keep it in the original case it came with but I would recommend putting it in your own rack. It works in the case that it shipped with but that case looks to be kind of a DIY. You will see in the photos. It takes up 48HP. Solid module build."

Musikmesse: KORG Monotron Analogue Ribbon Synthesizer

"Analog synthesis returns, in the legendary KORG tradition
Korg is no newcomer to the joys of analog synthesis. Back in the 1970s, our astounding fully polyphonic PS-3000 Series and our affordable semi modular MS Series set the bar for creative musicians around the globe. Surely one of the most popular of Korg's analog synthesizers was the coveted MS-20, famous for its dynamic sound creation capabilities and its fat, snarly, expressive filter. Kept popular by dance and electronic artists, this legendary MS-20 filter came back to life using the Component Modeling Technology in Korg's Legacy software collections. Now you can experience the glorious, evocative MS-20 filter along with true analog synthesis in Korg’s new monotron Analogue Ribbon Synthesizer!!

Analog on the go!
Powered by two alkaline AAA batteries, the compact monotron can be held in one hand. Although small enough to easily carry with you, the amazing monotron is packed with KORG's legendary analog technology, generating thick and powerful sounds. Concentrating on the most important sound parameters, the controls have been streamlined as much as possible. The panel contains only five knobs and one switch. With this level of simplicity, now anyone can easily enjoy the world of analog synthesizers.

Product Highlights:

* Full-fledged, true analog synthesizer: VCO, VCF, LFO

* Inspiring, easy-to-play ribbon keyboard

* Intuitive, fun-to-tweak controls

* Features the same classic analog filter found in the legendary Korg MS-10 & MS-20

* Filter any external source using the audio input jack

* LFO can modulate either pitch of filter cutoff

* LFO Rate knob features cool LED visual indicator.

* Battery operation and palmtop size equals true portability

* Internal speaker/headphone jack lets you enjoy the sound anywhere – alone or with friends!

Ribbon controller keyboard offers easy expression
Borrowing the enjoyment of performing with a simple touch from Korg's wildly popular KAOSS products, the monotron's ribbon controller keyboard takes this ease of use even farther. Simple finger gestures can produce expressive effects such as vibrato and glide. Used in a band, you can expand your possibilities by harmonizing with another instrument – or taking center stage for a monotron solo!

1VCO, 1VCF, 1LFO – Modular synthesis building blocks
The monotron's circuit is radically simple: one voltage-controlled oscillator, one voltage-controlled filter, and one low frequency oscillator. Since each knob directly applies a specific change to the sound, the process of sound creation is intuitive, and instantly understandable. Simple is best. Gone are the deep lists of presets and parameters typical of today's synthesizers. Instead, the monotron encourages exploration and experimentation. The monotron provides the joy of sonic creativity that's at the heart of analog synthesis, making it an ideal choice for someone who is new to synthesizers, or for musicians who wants to expand their sonic palette.

The famous Korg filter
The monotron uses the same highly acclaimed VCF circuit as KORG's classic MS-10 and MS-20 semi modular synthesizers. Originally released over 30 years ago, these instruments are still coveted today for their aggressive, dynamic filters. The VCF Cutoff knob sets the frequency or tone of the filter; the VCF Peak knob adds emphasis. A powerful filter is an essential aspect of any analog synthesizer, applying dramatic tonal changes to the sound, and projecting an intense personality that will stand out in any live performance.

Semi modular satisfaction
Just as on the original MS-20, the monotron's filter can be "patched into," allowing any external audio source to be processed by the monotron's filter. The input jack (AUX input) built into the monotron's compact body inserts the AUX input into the signal path right before the VCF. This provides a great way to connect a KAOSSILATOR, a keyboard, a guitar, a digital audio player or even an un-mixed track to the monotron and enjoy tone-bending filter effects.

Versatile LFO provides audio – and visual – excitement!
You can switch the LFO to control either the oscillator pitch or the filter cutoff frequency. Both LFO Rate and LFO Intensity knobs are provided. As you turn the LFO Rate knob – featuring an embedded LED – the speed of the modulation effect and the speed of the blinking LED will change in tandem. Turning this knob can add another level of impact to your live performances.

Listen anywhere – alone or with friends
A miniature speaker is built into the monotron. Along with the battery operation and compact size, this feature allows you to enjoy the monotron anywhere, at any time. The ultimate in compactness, this system brings you new possibilities for performance. There's also a headphone output that you can use when creating sounds at home, for recording, or for connecting to an amplifier or PA system."

Synclavier Go! and Synclavier Pocket! for iOS Released

You can find some demos in the archives. The press release:

NOVA SCOTIA, CANADA: having turned heads and opened ears with a show-stopping showcase at The 2019 NAMM Show in Southern California, January 24-27, newly-formed Synclavier Digital is proud to announce availability of Synclavier Go! and Synclavier Pocket! — placing a re-creation of the seminal Synclavier® II Digital Synthesizer’s sound engine from which they take their names into the respective hands of iPad and iPhone/iPod Touch owners as awe-inspiring iOS apps, allowing all the famed FM (Frequency Modulation) and Additive (harmonic) synthesis capabilities to be brought forward forty years for all to musically marvel, at a fraction of the original’s prohibitive pricing thanks to today’s technology, while also effectively emulating the iconic instrument’s intuitive panels of easy-to-touch red backlit buttons and iconic control knob in easy-to-use user interfaces — as of March 5…

Put it this way: while the still-highly-coveted brand of Synclavier® — synonymous with high-end audio production technology that blazed a trail through the Seventies and Eighties before stalling in the Nineties — is in the midst of a galactic reboot, thanks to Nova Scotia-registered Canadian Corporation Synclavier Digital, established in 2018 to re-create a modern iOS-based version of the Synclavier® Digital Audio System, Synclavier Go!, its inaugural iPad offering, is far from being a clone, however... to all intents and purposes, it is a Synclavier®!

So how, exactly, did yesteryear’s trailblazing technology that commanded a princely six-figure sum end up available on Apple’s pocket-friendly iOS platform in true needs of the many outweighing the needs of the few style? Simply speaking, when New England Digital (NED) went bankrupt in the Nineties, technology finally having caught up with the cutting-edge company concerned, co-founder Cameron Jones — co-inventor of the Synclavier® — bought the intellectual propriety rights to the trailblazing series of synthesizers and digital audio systems sharing the notable name.

Rebel Technology CLK Demo

Published on Jun 8, 2018 Rebel Technology

via Rebel Technology

"CLK is a 4HP triple clock generator that outputs three synchronised clocks. It comprises of a master clock and two dual function multiplier/dividers. Turn clockwise to multiply, anti-clockwise to divide. The outputs are always perfectly synchronised. Use it to feed several trigger sequencers or to generate instant ‘four on the floor’ style patterns.

The top knob sets the master clock, ranging from 40 to 200 BPM. The top jack outputs the master clock as 16th notes.

The middle and bottom knobs either multiply or divide the master clock, depending on whether the knob is turned clockwise (multiplication) or anti-clockwise (division) from the centre position. At 12 o’clock they output the same clock as the master, that is to say they multiply / divide by 1.

The middle knob values are 1 in the centre, then 2, 3, 4, 6, or 8 times as you move away from 12 o’clock.

The bottom knob outputs 1, 2, 4, 8, 12 or 24 times multiplication or division.

BX-13 V3 Expanded Bus Converter Version 3

images via this auction.

"For about ten years, Roland Corporation and other manufacturers produced a range of unique, very high quality 24-pin guitar synthesizer controllers. With the advent of the contemporary Roland 13-pin standard, vintage guitar synth owners could only access the latest in guitar synthesizer technologies with the incredibly rare, hard-to-find Roland BC-13 Bus Converter.

The BX-13 V3 is the answer for vintage guitar synthesizer players who want to access modern guitar synthesizer technology while playing their treasured vintage guitar synth controller. The BX-13 V3 is more affordable than the typical "collector" prices on the Roland BC-13, and it has more features.

This diagram shows how the Roland BC-13 uses the Resonance knob to switch guitar and synth on and off. The BC-13 uses the Resonance Knob (CV#2) in a way that is very similar to the Mode switch on the vintage GR-series guitar. But rather than having a three-position switch, the knob has three "zones." The first zone is guitar only, the middle zone is guitar and synth, and last zone is synth only. Confusing? Yes.

As you can imagine, it is almost impossible to quickly and accurately turn guitar and synth signals on and off.

The BX-13 V3 improves on the BC-13 by adding two dedicated foot switches with LEDs instead of using the Resonance knob. One foot switch is for Synthesizer Output, and one is for Guitar Output. Nothing could be simpler for controlling the outputs of your Synth and Guitar signal. In addition, the BX-13 V3 in enclosed in a rugged, stomp-box type enclosure. The BC-13 is an inline design, basically a giant lump in the middle of your guitar cable, much like the AC transformers popular with some manufacturers.

Top Panel Controls
The BX-13 V3 adds top panel controls for synthesizer and direct (humbucker) guitar output, plus a switch to select from guitar or hex fuzz sound for Roland G-202, G-303, G-505, or G-808 players. All three outputs can be accessed by selecting the hex fuzz sound with the BX-13 V3 and using the 1/4” Guitar output jack on the guitar.

A look at the schematics of various Roland guitar controllers reveals that no two are wired exactly the same. Likewise, the internal circuitry of a Roland GI-10, GI-20 and GR-20 differs with each unit. As a result, maximum volume levels can change with different guitars or different synthesizers. The original BX-13 used a "one-size-fits-all" calibration like the BC-13. Now, the BX-13 V3 adds a top panel control to easily fine-tune to synth volume output for maximum sensitivity and maximum output.

The BX-13 V3 also adds a top panel control for the direct (humbucker) output of the guitar as well. With the original Roland BC-13 and BX-13 this volume was fixed. Also, if you are using a Roland G-202, G-303, G-505, or G-808 you can also select the hex fuzz guitar output instead of the direct (humbucker) output. And, by plugging a Roland EV-5 volume pedal into the BX-13 V3 you can control the volume of the direct (humbucker) or hex fuzz output.

Buffered Electronic Connections:
The early Roland Guitar synth controllers, such as the G-202, G-303, G-505 and G-808, do not buffer the output of their volume controls. Later guitars, like the Roland G-707 and the Ibanez IMG2010, added a buffer stage to their volume controls. As a result, early guitars tend to "load" the input to the Roland BC-13, resulting in only 80 to 90 percent of the full volume output.

The BX-13 V3 solves this problem by adding an electronic buffer stage for the volume signal. The electronic buffer stage isolates the volume control signal so that any vintage guitar works smoothly with any modern guitar synthesizer.

Inputs and Outputs
Like a Roland BC-13, the BX-13 V3 has a 24-pin Guitar Synth a 13-pin Guitar Synth output connector. With only the 24-pin cable plugged in, the level of the direct (humbucker) guitar sound is controlled by the top panel guitar volume knob, and by the optional EV-5 volume pedal. If you want to vary the level of the direct (humbucker) sound using the volume knob on the guitar, then a second cable is connected from the 1/4” Guitar output jack on the Guitar Controller to your mixer or amplifier.

Compatible with Vintage Bass Guitar Synthesizers:
The BX-13 V3 has also been thoroughly tested with the vintage Roland bass guitar synthesizer controllers like the G-88. To test for compatibility, the G-88 was plugged into the BX-13 V3, then the BX-13 V3 was connected to a GI-20. The Roland GI-20 supports bass guitar synths with a switch on the back panel for bass operation.

Other Roland guitar synths, such as the GR-50 may not work properly, since they were not designed to handle to lower frequencies of a bass guitar.

A sound demo of the Yamaha MODX!

And the official press release:

"Yamaha MODX Incorporates Flagship Technology into a Lightweight, Affordable Line of Synthesizers

NEW YORK, N.Y. (September 14, 2018) — Yamaha today unveiled the MODX - a line of compact, lightweight, hybrid synthesizers inspired by flagship Yamaha synth technology to offer dynamic, expressive music-making at an affordable price.

This successor to the popular Yamaha MOXF line will be available in three models – MODX6 (61 semi-weighted keys), MODX7 (76 semi-weighted keys) and MODX8 (88 weighted and graded keys) – to fit the needs of synth players, keyboardists and pianists alike.

The power of the MODX offers musicians unlimited potential to create their own unique sound. The MODX sound engine draws on the same technology powering the flagship MONTAGE synth: AWM2 (Advanced Wave Memory 2) sample and synthesis engine plus a pure FM-X (Frequency Modulation) synthesizer modernized for dynamic synthesis and complex sound design. The MODX also incorporates Motion Control, a highly programmable control matrix for dynamic sound interaction. This gives musicians unparalleled ability to direct and manipulate their sound by interacting with their Performances in fine detail.

The MODX expands on the MOXF by offering a wide array of control and workflow elements. Seamless Sound Switching has been introduced in the tradition of MONTAGE to allow switching between Performances without any sound cutoff. MODX has DSP power with up to 13 simultaneous dual insertion effects and 3 system/master effects. MODX polyphony has been increased to 128 notes of stereo AWM2 (sample-based) plus 64 FM-X (Frequency Modulation synthesis.) The control panel now includes four faders, multi-function Super Knob and a touchscreen display.

At the same time, the MODX is housed in a lightweight body that makes it easy to carry to sessions, gigs and rehearsals. Also, like its predecessor, the MODX comes bundled with Steinberg Cubase AI DAW software for creating and producing music on the computer.

Synth players and sound designers will appreciate the deep programmability of Motion Control and the MODX FM-X synth engine. The versatility of the MODX and the wealth of onboard keyboard, synth, brass and strings sounds will appeal to keyboardists needing a wide variety of sounds, and 88 weighted-action keys, designed with the benefit of over 125 years of Yamaha piano craftsmanship and over 40 years of synth innovation, will suit any pianist.
“MODX sets a new standard for mid-range synthesizer sound, control and mobility,” said Nate Tschetter, marketing manager, Yamaha Synthesizers. “With advanced flagship technology in a lightweight, accessible package, MODX excels on stage, in the studio and in a wide array of creative situations.”

Pricing and Availability
The Yamaha MODX6 (MSRP $1,649), MODX7 (MSRP $1,899) and MODX8 (MSRP $2,399) are scheduled to ship September 27.

circuit bent KORG KAOSS PAD KP1 - Red

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

via this auction

"Way back in 1999 (its seems like longer) the Korg Kaoss Pad seemed like some kind of visitation from an alien technology. Aesthetically, it looks fairly primitive today, but back then it was the first of its kind. The technology was lifted straight from the Korg Z1, which was essentially a polyphonic Korg Prophecy released in 1997, but the KP1 was certainly the first stand alone effects device with a two axis touch pad controller.

If you want to read a review detailing the full specs of the KP1, you won't go far wrong with the Sound On Sound review from 1999 that can be found HERE. Essentially the KP1 features 60 different preset effects in six banks of 10 filters, modulation effects, delays. reverbs. SFX and sampling. Each effect preset has various different realtime control parameters assigned to the touch pad, so on a delay preset you might find that the delay feedback is increased as you move your finger on the pad towards the top left, or reverb might be introduced as you move your finger towards the bottom left etc etc. Normally when you remove your finger from the pad the effect is turned off, but at any point you can press the 'Hold' button and the effect is locked on in the last pad position you used.

The 'sample' presets are especially interesting, as they allow you to sample a sound into the unit, and then the sample is continuously looped as long as you are touching the pad. On the various sample presets the pad position is assigned to such things as the sample loop point, loop length, playback speed, forward/reverse playback etc.

As you can see, we have added a new control box to the side of the KP1. The box itself is made from a translucent red plastic, and we have installed several LED's inside so the whole thing lights up when you turn the unit on....... Nice! :-)

The control box houses a 16 way 'bend bus' switching matrix, and a clock speed knob. There is also another new switch mounted on the main casing just in front of the new control box which switches between the normal clock speed, and the new clock speed knob.

The new clock speed knob controls the running speed of the onboard sample RAM. This means that it will control the playback speed of any samples, the length of both the delays and reverbs, and the depth of any other effects that use the sample RAM, such as flanging or chorus. This works independently of any other effect or pad settings.

The clock speed also appears to control the sample rate of the RAM. On the KP1 the clean input signal is always run though the A/D and D/A convertors before reaching the output as there is no true bypass. This means that even when there is no effect running, the clock speed knob will change the sample rate of the input signal. This allows you to take a normal input and take the sample rate down to give drum loops more punch and dirt, until at the bottom of the knobs range the input sounds like its playing back through some kind of underwater drug experience.

The switch allows you to quickly switch back to the standard KP1 clock. Unlike many units that can be re-clocked in a similar way, on the KP1 you can freely switch between the standard clock speed and the new clock speed knob at any time, without the unit locking up or crashing.

The 16 way 'bend bus' switching matrix allows you to apply various kinds of comb filters, pseudo ring modulation, bit crushing, distortion, and what can only be described as audio smearing™ to any affect that uses the sample RAM in any respect. Each switch has a certain effect that is usually associated with it, although its effect can be altered depending on which other switches are activated simultaneously. You have to activate more than one switch at a time for any effect to work, but when two or more switches are activated their associated effects will combine to produce something entirely new. The demos below do tend to highlight the savagely brutal end of what this machine can do, but thats only because its more fun! It is very keen on distorting sounds way beyond the outer limits of what is strictly healthy, but it's also capable of producing a range of more subtle and sometimes strangely beautiful alien sounds.

The final, and we think you'll agree, most important mod to this machine, is a new spiral backing to the touch pad. You might ask why, but it would probably be more appropriate to ask, why not? Since when have we needed an excuse to make anything look more psychedelic? ;-)

The unit does very occasionally crash and lock to one effect when you quickly change preset effects with the clock speed set low. For some reason this mainly happens with the filter effects, but with a little practise it is completely avoidable and simply restarting the thing resets it. The unit will be supplied with a power supply (240v with a UK plug), and the two page manual can be downloaded from HERE

Round the back is a midi output (sends midi control changes from the pad), atereo inputs (phono and line level) and outputs on phono sockets, a mic input so you can process a vocal live, and a direct / FX loop switch. This final switch removes the original signal to give a 100% effect output for use on a mixing desks FX sends.

Below are some demos of what this machine is now capable of. The first is a fairly long and brutal destruction of a very simple pattern supplied by a Yamaha RM1X. The second demonstrates what can be done to delays, and shows what can be created by the unit itself without an input when the mods are applied to the reverb effects. The third demo is the result of processing a breakbeat, again from a RM1X. The fourth is a stereo ambience and the final demo is a continuation of the first, only with more of a bad trip feel to it."

Rebel Technology Bit Reactor

via Control on Facebook

"NEW Bit Reactor care of the UK's Rebel Technology is now available. Bit Crusher / Down Sampler / 10HP"

"The Bit Reactor is a hardware bit crusher and downsampler. It has no program or CPU, it digitises without software. It takes whatever signal you give it and crunches it up into digital atoms.

We live in an analogue world. But most of the media that we encounter today is digital: an attempt to reproduce real-world signals with a stream of 1s and 0s.

In the realm of modern electronics there’s plenty enough processing power to create a crystal-clear digital copy of pretty much any analogue signal. The Bit Reactor, on the other hand, explores what can happen when we take all that processing power and throw it out the window. Think of an old Atari or NES in all its 8-bit glory and you’ll start to get the idea.

There are two main parameters to play around with on the Bit Reactor: bit depth and sampling frequency. Less bits means the signal levels can’t be properly reproduced, and this can result in anything from a fairly subtle to a super-clipped square wave distortion and its associated harmonics. Meanwhile the sampling frequency determines the maximum frequency that can be accurately reproduced. As it is decreased, the higher frequencies present in the input can no longer be accurately recreated. But rather than these frequencies simply being discarded, they reappear at a different, enharmonic frequency due to the phenomenon known as aliasing. These effects, on their own and in combination, create unique audio artefacts that range from subtle colouring to complete destruction.

The 8 small LEDs surrounding the middle knob represent the number of bits being used (each LED represents 1 bit); as the knob is turned clockwise, more bits are added and more LEDs are lit.

The sampling frequency increases as the knob is turned clockwise. At the fully anti-clockwise position the sampling frequency will be so low that virtually no note will pass through unscathed.

Both of these parameters can be modulated via the CV inputs and the modulation depth is also adjustable for both parameters. Modulation is positive, meaning an increase in CV corresponds to turning the knob clockwise, and vice versa.

Finally there is an input level adjustment to provide a small boost or cut as required to get the maximum tonal variance out of the bit crush. To fully exercise the dynamic range of a handful of bits the input should be high but not clipping. If the input level is low, there won’t be a marked difference when at the lower end of the bit knob. This can be demonstrated by taking a rather extreme example: at 4 bits, the output is stepped with a resolution of just over 300mV per step. That means that if the input level were 300mVpp, at 4 bits the output would already be a square wave (one step), exactly the same as when using 3, 2, or 1 bit.

On the other hand, an input level that is too high could also be undesirable. The module’s input has a limiting circuit which caps the signal at 5Vpp. With an overdriven input this limiting circuit will already be distorting the signal before it even gets put through the analog-to-digital converter. The higher the input level, the more it will be distorted. There will be those amongst you, I’m sure, who will say ‘And the problem with that is..?’ However if the goal is to only colour the sound with the crushing/downsampling and nothing else, the option is there to cut the input down to size.

Some History on the Development of the Moog Little Phatty

For whatever reason a thread cropped up on AH questioning Bob Moog's involvement with the Little Phatty and specifically whether he was involved at all. One, I remembered the project started when he became ill and two, core bits of the tech is based the Voyager! Even if he wasn't hands on, much of the technology that makes it what it is would still have come from him. I don't get it. That aside the following is an intersting insight to Bob Moog's involvment as well as the involvment of his team.

"Bob was completely involved in the genesis and design of the Little Phatty. He was actively working on the project when he became ill. He wired up the first prototype, which was built from a modified Voyager analog board wired directly to a panel of pots. The original idea was a stripped-down all analog two-oscillator performance synth, with a minimal but effective feature set and a knob per function on the panel. No MIDI, no patch memory.

This concept did not survive any opinion surveys, which all indicated that MIDI and memory were required features. Once we added a digital board to the design, the knob-per-function interface became too expensive to keep cost within our target for an inexpensive two-oscillator performance synth.

So, the final Little Phatty interface was conceived, using a knob per synth section rather than a knob per function. I believe this layout was conceived by Axel Hartmann. The Real Analog Control [RAC] system, where pots are both scanned for digital value and physically switched into the analog circuits which they are controlling, was conceived by Steve Dunnington.

So, Bob Moog brought the Little Phatty project into being, and shaped its original feature set. Most importantly for this project, he select Cyril Lance in particular to be his assistant/successor, after a very discriminating search. Cyril stepped in at the point when the project code-named "el P" was making the transition from all-analog to midi & memory, so he designed the Little Phatty digital board as one of his first projects for Moog Music. Prior to this, of course, Cyril had been a consulting engineer, a particle physicist (graduate of Cornell; same university as Dr. Moog), and of course a touring blues guitarist of some repute. Even though the digital board design was ultimately Cyril's, it was done in close reference to the digital board of the Voyager, which was rather similar to the digital board of a Memorymoog. As for the Little Phatty analogue board, it is comprised almost entirely of circuits taken directly from the Moog Voyager. The're the exact circuits Bob designed well before his untimely passing, simply configured for a different synth concept. The circuit layouts and corresponding component values for a given little subsection are generally identical between the Voyager and LP.
A notable exception is the Little Phatty's Overload circuit, which was designed and painstakingly tweaked by ear by Steve Dunnington. I think he did a good job with that circuit.

So, the LP has Bob's Voyager oscillators and Bob's Voyager envelopes (complete with quirks and circuit errors just like on the Voyager), the same implementation of the ladder filter (only times one instead of two), the same VCA design. An instrument is a whole The digital control, the RAC system, the panel layout, overload... these things were designed by other people, all of whom desired to continue Bob's legacy and to create a real, playable instrument that stood on its own merit. I should mention that the original Little Phatty firmware was written by Chuck Carlson, a programmer who had worked with both Moog and Buchla prior to working on the LP.

I have been the alpha tester for the Little Phatty firmware as it has developed, and I've gotten to make a suggestion or two along the way.

I'm writing this instead of getting sleep here at the NAMM show, so I'd better leave it there.

Hope this helps,
Amos"

Note Axel Hartmann also designed the interface for the Voyager, and a numbe of other synths. Check out this post for the list of synths. You might be surprised. He is the face of many of our modern day knob laden synths.

"A powerful bass synth with a sound source based around a vacuum tube oscillator.

The acid bass machine with the pinnacle of modulation and distortion.

Even today, when digital technology allows electronic musical instruments to simulate any sound imaginable, people seek the warm harmonics and distortion produced by analog vacuum tubes. This distinctive sound has a quality beyond words that sets it apart, and cannot be captured by a response curve; it's the unmistakable sound of tubes.

The volca nubass is the first analog synth to be equipped with a Nutube new-generation vacuum tube in its oscillator. Vacuum tube plus analog means that the sound is warm, thick, and rich. The familiar transistor ladder filter gives it the character of a classic bass machine, along with overdrive, and huge-sounding distortion.

An acid bass machine for a new generation combines classic sound with the power of modern synthesizer design. It's the volca nubass.

The fusion of a newly developed vacuum tube oscillator with a classic ladder filter

A vacuum tube oscillator circuit forms the heart of volca nubass, utilizing groundbreaking Nutube technology

The Nutube is equipped with two vacuum tubes; one is used in the oscillator to generate a sawtooth wave or square wave. The other vacuum tube is used in the drive circuit of the sub oscillator, adding depth and warmth one octave below the oscillator. This oscillator and sub oscillator provide a circuit structure that brings out the harmonic character that only a real vacuum tube could provide.

A transistor ladder low-pass filter that produces a distinctive sound

The low-pass filter defines the sound of this bass machine; it uses a transistor ladder design found on classic analog bass synths. This filter is uniquely dynamic in the way it affects a sound more than just ranging from bright-to-dark. Its wide range of timbral possibilities makes it ideal for a broad variety of dance music; you can use it to create the distinctive modulation that can be heard in acid house, or increase the resonance to bring out a sharp character that's appropriate for techno.
Analog driver circuit

nubass is equipped with overdrive that uses an analog circuit reminiscent of a classic stompbox. Turning the knob toward the right compresses the volume while causing mild distortion, adding thickness to your bass sounds. The tone knob also lets you adjust the crispness of the high-frequency range.
