IK Multimedia UNO Drum First Impression Jam | haQ attaQ

Published on May 8, 2019 Jakob Haq

"What’s this? UNO Drum? 🥁 Yup, it seems that IK Multimedia has added an analog and digital drum machine hybrid to their arsenal of musical hardware tools and some how ... I’ve gotten my hands on one. First impression drum jam anyone?"

Critter & Guitari - LFOmlog for Organelle

Published on May 8, 2019 Critter & Guitari

"Download patch here: http://organelle.io
LFOmlog is a synth with different LFO control of Cutoff, Resonance, Attack, and Release! Set the rate of each LFO and let the patch modulate. Use the built-in sequencer or latch function to play some notes while you vary the rate, depth and offset of each control. Send the two oscillators in and out of tune with each other for extra weirdness."

Dual Volca Modular | Dark Ambient Session

Published on May 8, 2019 littleBIGsynths

"Hey guys! Sooo, I couldn't help myself and ended up purchasing a second Volca Modular! After playing with my first vModular for awhile, I kept thinking about how much fun it would be to have 2. 😁

The vModular alone is a ton of fun and capable of some very interesting sounds; adding a second one opened up tons of extra modulation and sound possibilities. Once I started playing with them, I then thought it would be a good idea to pick up a dual tier stand, for ergonomic and visual purposes. 😏

For this jam, I went for some dark cinematic/ambient vibes. I didn't include any other Volcas or PO's this time around, in order to get more of a standalone, micro "modular" experience. 😉

Anyways, I hope you guys enjoy this video. As always, thank you for watching, littleBIGsynths. 🙂"

Analog Arpeggiator / Groovebox/ Synthbox with Yusynth Metalizer

Published on May 8, 2019 Andreas Remshagen

"A Demonstration of another Synthesizer-Component i`ve made.
It Incudes 4 VCO`s, each contains Square/Sine/Triangle and Saw-Wave. Every Wave can be mixed into the Main Signal.
The VCF is a Steiner-VCF. Two ADSR drives the VCF and the VCA.
The Metalizer can be feeded with each Waveform that is mixed to
the main Signal. The internal clock drives 4 switchable arpeggiator-sections. the arpeggiator can be set from 1 to 10 Steps.
Internal clock and external clock is possible and there is a gate-out. In the arpeggiator-section i added an "Akzentuator", it gives out an adjustable Accent on selectable positions (1-0-1-0; 11-00-11-00; 111-000-111-000 etc) The accent sets the VCF frequency.
The box can also be used as a normal analog-synthesizer with each VCO-CV in and a master/all VCO-CV in

VCO, VCF, VCA and Metalizer-Design comes from Yusynth (www.yusynth.net)
ADSR-Design comes from Rene Schmitz
(www.schmitzbits.de)
The Arpeggiator and the Akzentuator are modified 4017 countercirquits modified by myself"

Rubicon & Dixie FM Routing With Planar

Published on May 8, 2019 Intellijel

"Planar is a fantastic tool for routing modulation. In this example Rubicon and Dixie are cross modulated by feeding the A and C inputs with FM modulation being sent from the B and D outputs. This means that quadrant B modulates the Dixe's FM1 input with Rubicon, D modulates the TZFM of Rubicon with Dixie, and the other quadrants fade out the modulation.

A sequence from Scales is sending a melody to Dixie, which is also clocking Steppy, and Steppy's OUT A is providing the TRIG in to clock the Quantizer.

#intellijel, #eurorack, #modular, #synthesizer

Planar's X and Y outputs are controlling Scales Pitch inputs, so with the XY button off, no new notes are quantized for Rubicon. With it active, new notes are sent to Rubicon and things become more chaotic."

Elektron Digitone Keys Sounds

Published on May 8, 2019 Perfect Circuit

"Read our article about the Digitone Keys here: https://www.perfectcircuit.com/signal...

Elektron has a new version of the Digitone that has a built in keyboard as well as a few other extras including individual stereo outs for all four channels and extra modulation controls. There are 8 knobs above the keyboard that control a preset set of voice controls as well as a set of 8 user programmable controls. The mod wheel and pitch bend as well as aftertouch and velocity from the keyboard can be routed as modulation sources to multiple destinations at once.

The synthesis of the Keys version is the same easy to use but great sounding FM engine from the original Digitone that also features the filters of subtractive synthesis.

Digitone Keys available here: https://www.perfectcircuit.com/elektr..."

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."
