Two important new releases from Sound Semiconducto

Two important new releases from Sound Semiconductor today!

The SSI2100 is a new generation bucket brigade delay, developed on a modern IC process for performance improvements and new features while preserving the “mojo” of such beloved and quirky analog delay circuits.

A 512-stage bucket chain allows a wide range of delay times from a clock frequency of 1kHz to over 2MHz. A novel circuit (patent pending) allows easy connection of multiple SSI2100’s for longer delay times without having to recalibrate inputs and outputs.

An additional benefit to daisy-chaining is access to intermediate feedback taps for interesting reverb and other psychoacoustic effects.

An integrated clock driver greatly simplifies external clock sourcing and is TTL-compatible, making a companion BBD clock IC unnecessary.

Also on-chip is a tetrode bias voltage generator that eliminates the need for externally providing the legacy “14/15 VGG” supply voltage.

The SSI2100 is available in a super-compact 8-lead SOP surface-mount package.

-------------

The SSI2160 is a budget single-channel VCA building block for high-performance audio applications. Voltage control of current-mode inputs and outputs allow an exponential gain range of +20dB to 100dB, with control provided by a ground-referenced 33mV/dB constant.

The device offers considerable flexibility for a wide range of design goals and applications. A unique mode control allows selection of Class A, Class AB, or in-between using a single resistor. The SSI2160 can be used as a high-quality building block for a variety of applications such as dynamic range processors, voltage controlled filters, exponential generators, and antilog converters.

The SSI2160 will operate on supplies as low as +8V for battery-powered devices such as guitar pedals, or up to ±18V in systems where maximum headroom is desired.

The SSI2160 is part of a family of affordable high-performance VCA’s from Sound Semiconductor.

Welcoming Decade Bridge to Thonk! TRIAD is an aff

Welcoming Decade Bridge to Thonk!

TRIAD is an affordable 3 oscillator square wave drone/noise/glitch synth, capable of generating a range of tones and sounds from strong lead type sounds to glitched out clicks and pops.

The 3 oscillators drive and reset each other in different ways depending upon the switch/button settings, and an external trigger, gate or clock can also be used to reset 2 of the 3 oscillators.

TRIAD works great as part of a drone or noise setup, makes for excellent sample fodder, and thanks to the neat “reset” input it can play along with drum machines and sequencers (especially when paired with a little low-pass gate).

TRIAD is powered by a 9V center-positive power supply or batteries.

A hands-on rhythm engine with a minimalist interface. Available from thonk.co.uk now!

The Drum sequencer from @ericasynths and @moritzklein0 is the latest edition in the mki x es.edu DIY Eurorack range.

Most drum sequencers are complex machines – packed with buttons and LEDs, all driven by a microcontroller. For this DIY Drum Sequencer kit, MKi and Erica have decided to take the opposite approach: a hands-on rhythm engine with a minimalist interface, built from just a handful of logic chips.

Each of the sequencer’s four channels is programmed in real time using a single button. Patterns loop automatically, can be shortened on the fly, and support half-time playback for slower, evolving grooves. Accents are handled using synced LFOs, while a simple resistor-DAC turns patterns into stepped control voltages – perfect for modulating pitch, decay, or other parameters.

Whether you’re looking to learn about sequencer design, sharpen your soldering skills, or just want a drum sequencer that plays like an instrument, this DIY kit packs surprising depth into a refreshingly simple interface.

A monster recreation of the original 1970s Elektor

A monster recreation of the original 1970s Elektor Formant modular system featuring 27 modules! Available now at Thonk.co.uk!

@ericasynths have pulled out all the stops and recreated an extended version of the legendary Elektor Formant synthesizer, a complete modular system that was originally released as a DIY kit by Elektor Magazine during the late 1970s.

Working in collaboration with Harald Antes of haraldswerk.de, Erica Synths have developed a modular system based on the original designs while also adding some new modules to take its functionality to the next level. The unique internal normalisation of the original system has been preserved, so the Formant system can also be played without patching, exactly as described in the original Elektor Formant manuals.

We thought this was really cool and we had to stock it.

The Hakai Labs / Danesi Designs Colour Vision Deficiency (CVD LED) is a high quality custom designed bi-polar 3mm Red/Green LED that’s been manufactured for the inclusivity of colour vision deficient (CVD) individuals without any sacrifice to those without a colour vision deficiency.

A small colour shift was made to the wavelength of the green side of the LED to push it closer to blue in the visible spectrum. This slight shift is enough to enable colour vision deficient individuals to fully distinguish between the red and the custom green/teal colours emitted by this LED.

IMMUTABLE MARBLES from @cctvfm is a black panel fu

IMMUTABLE MARBLES from @cctvfm is a black panel full-sized clone of Mutable Instruments’ best-selling open source Random Sampler. In stock now at Thonk.

Much like the interplay of its metamorphic namesake, Marbles specialises in random responses to an initial impact. The module is organised as three sections: the t section generates and processes clocks and triggers, the X section generates and processes voltages, and the DEJA VU section imposes structure, in the form of repetition, upon all the events generated by the two other sections.

Though thoroughly concerned with chance, the UI leaves plenty of options for imposing some semblance of structure. Sync it with external clocks, manipulate the orientation of generated elements, or introduce external CV and gate sequences! No matter what source causes the initial impact, Marbles will respond with elegant randomness.

This kit has the SMD parts pre-assembled, leaving only the through-hole parts to solder. These boards are also PRE-CALIBRATED, meaning no fussy computer nonsense is needed, just build it and go.

DIY Kit at thonk.co.uk now!

At its core, Hive is a four-channel stereo mixer with CV-controlled panning per channel, but like any other Vostok module, Hive comes with several quirks that make it a handy module for every system.

Each channel can boost incoming signals to perfectly match the level of your different modules, as well as bring pro-line level devices, such as desktop synthesizers or drum machines, into your rack.

The panning works with a custom panning-law slope of -1.5dB attenuation at the center position, ensuring smooth balance transitions either manually or with CV.

Several modules can be chained together using the dedicated connectors located at the back, allowing the use of other Hive modules as channel expansions or submixes.

Hive packs a bunch of useful features into a compact 10HP layout, making it a perfect stereo mangler, FX sub-mix system, end-of-the-line mixer, and much more.

Introducing a limited edition re-release of this i

Introducing a limited edition re-release of this iconic electronic instrument in DIY Eurorack format.

In stock now at thonk.co.uk - limited edition.

This module is a tribute to the pioneering work of Dutch musician and instrument maker Michel Waiswisz (1949 – 2008), who first invented the Cracklebox with Geert Hamelberg in the late 1960s.

The Cracklebox was a small, handheld device designed as a way to explore new sonic territories. It was one of the first electronic musical instruments to use circuit bending techniques in the creation of electronic music. It allowed musicians to manipulate and control electronic circuits in real-time, creating a wide range of unique and experimental sounds. Waiswisz used a circuit from a toy piano as the basis for the instrument, and then added a series of touch-sensitive pads that were connected to the circuit. When a player touched one of the pads, the circuit would be completed, producing a crackling sound.

The Cracklebox was probably the first commercially available portable self-powered alternative ‘keyboard’ analog electronic instrument with inbuilt loudspeaker. In the 1970s about 4000 Crackleboxes were built and sold by STEIM in Amsterdam. Nowadays many people refer to the The Cracklebox as the archetype of ‘glitch’ or ‘circuit bending’.
