micro wavepatterns [Busy Circuits ASQ-1 & System J Transcendant Filter]

video upload by zack dagoba

"This is my first experiment with the Busy Circuits ASQ-1

I'm using it in quantizer mode and sending it voltages from the 2 182 sequencers. It works by quantising any incoming voltage to whatever notes you select on the keyboard. Cool effect!

Also in the patch is the System J Transcendant Filter - lovely sounding m-m filter!! Thanks to James at System J for sending it to me ❤️❤️❤️

The other interesting thing about this patch is that I'm using a Kenton CV to MIDI converter so I can tigger any midi synth from the euro-rack rig. Neato!

In this case I'm triggering the Waldorf Microwave 2 made in the mid 1990s

Bye for now!"

---

Note this is the first post to feature System J and the Transcendent Filter. The following is some info via the System J website. You can find additional posts on the Busy Circuits ASQ-1 here.

"After recently designing some custom circuits for a client I've decided to make a few of them available as limited run eurorack modules - the first of these is the Transcendent VCF. Modules are custom built using mostly NOS through hole components in keeping with the original circuits and style. Panel is screen printed anodised black aluminium. This module is fairly deep at 67mm so please make sure that it will fit in your modular case. Limited run of 20 production units only. Available from June 25th. Demo clips coming soon...
if you are outside the U.K please select International Tracked & Signed shipping option during the checkout process.
Module Details:
The Transcendent VCF takes its inspiration from the classic British mono synth of the 1970s and, while not a direct clone, it brings the distinctive and unique character of that well-loved machine to the eurorack world.

The filter is a 2 pole, 12db/oct design with selectable low pass and band pass response. The resonance behaviour is quirky and unpredictable and is key to the unique sound of the Transcendent - as you advance the resonance control there are many sweet spots to explore, from subtle harmonics to howling resonant peaks.
At high resonance levels the filter will self oscillate and can be utilised as a sine wave oscillator.
CV1 input is scaled for a v/oct response and can be used for key follow effects as well as standard modulation. It has its own attenuator.
CV2 input has a wider range and is suitable for deeper modulation duties - from an LFO or envelope generator for example. It also has its own attenuator.
Two audio signal inputs are available, both with dedicated attenuators.
The final output also features a level control.



Specifications:
Width: 16hp
Depth: 67mm
Current draw: +12v 20ma, -12v 20ma
Frequency: <8hz - 18khz"

Jordan Rudess plays the Megawave, Obie One, CATO, and Triptych from Syntronik 2

Jordan Rudess plays the Megawave modern virtual synthesizer from Syntronik 2
video upload by ikmultimedia

"Watch Jordan Rudess plays one of the classic synths of Syntronik 2 - the Megawave. The Megawatt features the powerful wavetable synth sounds of the original Waldorf Microwave, a classic digital/analog hybrid. The Microwave was the heir to the PPG Wave legacy with its sweepable digital wavetables and Curtis chip analog filter. The unit we recorded is the most coveted Rev A version."

And a few more:

Jordan Rudess plays the Obie One modern virtual synthesizer from Syntronik 2


"Watch Jordan Rudess plays one of the classic synths of Syntronik 2 - the Obie One. The Obie One is our recreation of the innovative Oberheim OB-1, excellent at creating classic and fat sounding bass, pad and lead sounds. The new 4-pole slope in our O-Type state variable filter model in Syntronik 2 now captures the distinct difference between the 2- and 4-pole filter sounds of this excellent hardware synth."

Jordan Rudess plays the CATO modern virtual synthesizer from Syntronik 2


"Watch Jordan Rudess plays one of the classic synths of Syntronik 2 - the CATO. The CATO captures the distinctive analog sounds of the Octave Cat SRM and its SSM filter. The pure-analog tonality of this synth is huge, and its modulation capabilities allow for truly unique and stylized timbres. Able to create gigantic Moog-style basses, the CAT can also go in its own sonic direction with its clever oscillator sync implementation."

Jordan Rudess plays the Triptych modern virtual synthesizer from Syntronik 2


"Watch Jordan Rudess plays one of the classic synths of Syntronik 2 - the Triptych. The Triptych is based on the warm sounds of the classic Korg Trident with its separate synth, string and brass sections. The Trident was basically a 2-oscillator Korg Polysix combined with a convincing string machine with dedicated ensemble chorus and a paraphonic brass synth. It is a beast of a synth capable of a wide range of classic analog synth and stringer sounds."

"This great filter is the early 9v AC version, with the SEM filter, very raw and powerful sounding"

SEM filter? The SEM is a state variable 2-Pole. Via Wikipedia: "The SEM featured a two-pole filter that could operate as a lowpass, high-pass, bandpass, or band-reject filter, giving it a different sound than the filters of the Moog or ARP filters popular at the time."

Analog Renaissance Tests Out the New Sound Semiconductor SSI2164

You might recall Sound Semiconductor announced the availability of the SSI2164 QUAD VCA chip back in March of 2018 (data sheet here). The SSI2154 is technically an updated design of the classic SSM2164 found in the Octave Voyetra Eight, Siel DK 600, Opera 6 & Kiwi, and the full blown Waldorf Wave. Analog Renaissance was commissioned by Sound Semiconductor to write an application note on the chip in practical use. The following are some of his findings including a couple of demos and a cool oscilloscope synth cat. :)

via Analog Renaissance:

"Sound Semiconductor (basically SSM risen from its ashes) hired me a few months back to write an application note AN701: 'Designing Voltage Controlled Filters for Synthesizers with the SSI2164' for them.

This job quickly escalated because while analyzing this IC's design, it became apparent that it is far more capable, due to its advanced design over its predecessor the SSM2164 (and its cheap knockoffs), than what I expected from reading the datasheet.

Its exceptional THD and noise specs allow building ultra clean filters that are virtually distortion and noise free, its excellent channel tracking means that it is very suitable for multi-mode filters which rely on precision and inherent in its design is the same type of asymmetric distortion responsible for the legendary SSM2040’s sound and more.

The 32-page manuscript is now being reviewed and edited to match their house-style, and should be made public soon. Imho it's quite extensive and covers next to SSI2164 specific content quite a bit of VCF design in general, circuit history and some novel stuff.

As there are already more than enough datasheets, application notes and books filled with non-working (read: tested in spice) nonsense, I accepted this job on one condition: build, test and since it's about synthesizers, hear everything before writing about it.

The small building blocks were breadboarded, but as this type of construction quickly becomes impractical for larger designs, certainly when they need multiple sources and control voltages, and impossible to do meaningful measurements on beyond a certain level, due to coupling and EMC issues, I built 3 filters in eurorack format, which also allows for quick connection to other synth and audio equipment.


SSI2164 - 2040 VCF Published on May 5, 2019 dnaab136

The first one, on the left, is an ultra-clean 4-pole VCF with a SNR better than 107dB (A-weighted) and THD is less than 0.0066%. Both these numbers are the limit of my current test equipment.

The second one, in the middle, is a VCF that employs the SSI2164's SSM2040-like non-linearities and for the first time since the early 80's done monolithically.

The 3rd one, on the right, expresses my contempt for what can and can't be done by ignoring a few mathematical constraints and is a self-oscillating 6dB/oct (1-pole slope) VCF.


SSI2164 - Mathematically impossible self-oscillating 6dB/oct VCF Published on May 6, 2019 dnaab136

Math wasn't happy with this, so it sounds a bit angry and, one of its main features is its capability of transforming sine waves into cats.
one of its main features is its capability of transforming sine waves into cats.

All 3 modules borrow 2 things from power electronics: A FET-bridge that allows plugging in the power cable in any orientation, without the voltage drop associated with diode bridges, and an S-Curve dimmer, originally intended for incandescent lamps but here used for a reversing attenuator with a dead zone in the middle.

The first 2 are multi-mode and have next to the standard 4-pole output a few extra outputs: 2 & 4-pole band-pass and a 2-pole low-pass. All outputs have the exact same phase response and can be mixed to obtain variable slope filters.

I'll bring these to Superbooth in one of these waldorf KB37 keyboards, with some basic VCO, LFO, ADSR and mixer modules for you to play with along with a printout of my manuscript and what is already edited (about 2/3rd) for publication."

Waldorf to Introduce New KYRA - All FPGA VA Synthesizer Based on the Exodus Valkyrie at NAMM 2019

Yes, this is real. Waldorf is teaming up with Exodus Digital on their recently announced Valkyrie FPGA synthesizer. It's worth noting the Novation Peak is also FPGA based, however not fully, as it utilizes analog filters. There are also some DIY FPGA synths. A fun side note is that this is the earliest NAMM post to go up for a single year's event. :)

Here's the press release:

Waldorf Music makes world’s first fully FPGA powered synth fit to fly for full production launch at The 2019 NAMM Show

REMAGEN, GERMANY: hot on the heels of having turned heads and opened ears with its innovative flagship, Quantum, a high-class hybrid synthesizer showcased to widespread critical acclaim at The 2018 NAMM Show in Anaheim, California earlier this year, high-quality synthesizer developer Waldorf Music is proud to announce a full production launch and general availability of Kyra — the world’s first fully FPGA (Field-Programmable Gate Array) powered synthesizer featuring 128 voices (regardless of settings and effects), each with 10 oscillators per voice, and eight-part multitimbrality (with each part having its own dedicated nine-module effects unit) — at The 2019 NAMM Show, January 24-27, in Anaheim, California…

As an extremely powerful VA (Virtual Analogue) synthesizer literally like nothing else out there — thanks to leveraging the latest FPGA technology to significantly outperform legacy DSP (Digital Signal Processing) powered competition, Kyra’s crowning glory comes courtesy of its state-of-the-art audio quality: think 32x oversampled hardware with dual wavetables providing over 4,000 waveshapes! With 10 oscillators — that can be doubled to 20 by using two voices — each offering a wide range of features, including true stereo operation, hard sync, FM (Frequency Modulation), and ring modulation, Kyra starts shaping up as a serious sonic force to be reckoned with... without even factoring filtering into an already seriously impressive-sounding instrument! Indeed, Kyra’s resonant filters are accurate oversampled emulations of classic analogue ladder filters with 2- and 4-pole configurations (offering -12dB/oct and -24dB/oct of magnitude decrease, respectively). Saying that, two linked or independent filters can be used in Dual Voice mode, making for even more creative options. On top of that, there are three envelope generators, three stereo LFOs (Low Frequency Oscillators) with 64 shapes and MIDI (Musical Instrument Digital Interface) clock sync, an arpeggiator, full keyboard microtuning, and true polyphonic portamento, as well as a comprehensive 18-channel modulation matrix to Kyra’s notable name.

Notably, Kyra comes highly specified for effects, each of its eight parts featuring a three-band EQ with sweepable mid, dual tube limiters, formant filter, distortion, six-stage phaser, stereo digital delay, comb/flanger/chorus/doubler unit, and a programmable reverb. All effects units on all parts can be used simultaneously and run at Kyra’s native 96kHz sample rate.

Kyra clearly delivers when it comes to connectivity by boasting four assignable, balanced 32-bit/96kHz stereo outputs, a headphone output, low-latency DIN MIDI, a fully class-compliant USB2 implementation for MIDI, and a stereo 24-bit/96kHz audio stream for each of its eight parts. Production-wise, there is also a USB (Universal Serial Bus) audio return feature, so Kyra can render final DAW (Digital Audio Workstation) audio under ASIO (Audio Stream Input/Output). An ASIO driver is provided for Windows users while Mac support is out of the box.

But if any aspects of this impressive instrument already have a ring of familiarity about them then Musikmesse 2018 in Frankfurt am Main may have played its part. Put it this way: Waldorf Music CEO Joachim Flor found himself transfixed there. “It was more of a coincidence to have discovered Valkyrie during a tour of this year’s Frankfurt Music Fair, but I was immediately aware of the fact that this was probably one of the most exciting synthesizers of recent years,” he admirably admits. “I got into conversation with its independent UK developer, Manuel Caballero, and I’m now looking forward to working with this talented, innovative individual, who is also a great guy! Under the direction of Waldorf Music, Valkyrie flies forth into a joint production project called Kyra, which will be shown and delivered at NAMM in 2019.”

Fortunately for Manuel Caballero, the feeling was clearly mutual — Musikmesse mission accomplished. “After nearly four years in the making, I went to Musikmesse with the intention of finding an established partner for Valkyrie,” he reveals. “There's little doubt that Valkyrie's reveal at Musikmesse caused quite a stir in the synthesizer world and I had set the bar high for potential partners to bring the instrument to market. As a result of this, I'm pleased to announce a partnership with Waldorf Music. Few companies can match their track record of innovation and delivery spanning several decades. Working with Joachim Flor and his technical and design team to achieve this is an exciting and efficient partnership as we work together to launch the instrument at NAMM in 2019. Waldorf's proven heritage in product design, manufacturing, and distribution leaves me to do what I do best, which is applying the most advanced technologies to the art of music, and I look forward to a continued deep working relationship with the Waldorf team.”

Kyra is initially scheduled for full production launch at The 2019 NAMM Show, January 24-27, in Anaheim, California, competitively priced at €1,899.00 EUR as a desktop/rackmount model (with a keyboard version to follow later in 2019).
