Timiszoara is a stereo, Eurorack compatible, voltage-controlled multi-effect signal processor based on the popular Spin Semiconductor FV-1 DSP chip. It features a full stereo signal path with two adjustable audio inputs, two outputs, and a stereo voltage-controlled wet/dry mixer. In addition, there is a microSD memory card slot on the front panel that allows for loading factory and custom effects without any restrictions or copyright protection, which means you can use many effects available on the Internet and even create your own.

Effect programs are organized in banks of 8 and can be selected using a rotary encoder, as well as CV and trigger signals. Timiszoara features a crisp OLED screen that displays the program parameters and its name. It also facilitates navigating the list of banks. Up to three parameters per effect can be controlled from the front panel with illuminated slider potentiometers and dedicated CV inputs.

We have prepared quite a few banks of algorithms (176 in total) that cover most effects needs: delays, reverbs, filters, modulation effects (such as choruses and flangers), pitch shifters, and, of course, shimmers (no multi-effects unit would be complete without its share of those). However, we wanted to ensure that users had access to some more adventurous programs, so we created some special banks to allow you to take a walk on the wild side.

DESCRIPTION

The Odessa is an advanced additive oscillator module that allows you to create a wide range of sounds by adding up to 2560 sinusoidal components (harmonic partials). This lets you create everything from classic saw, square, and sine waves to completely unearthly sounds. The module offers a set of controls for shaping the harmonic spectra, including the number of partials and their distribution in frequency and amplitude. A spectrum analyzer with 12 multicolor LEDs provides visual feedback on your settings.

The series of harmonics can be manipulated to create different effects, similar to flanging and phasing. All partials are related to a common fundamental frequency, which is controlled by a single V/Oct input. The signal can also be modulated by exponential or linear (through-zero) means. Up to five detuned voices can be spread apart for a fuller sound.

Erfurt is a bi-directional digital counter, frequency divider, and component of our 8-bit Leibniz Binary Subsystem. It has multiple applications: the output of the counter may be used as a phase source driving a digital wavetable, connected to other Leibniz modules it may scan waveshapes in Jena, produce stepped voltages useful for making interesting glissandi with Drezno and any VCO, generate gate patterns animating the spectrum of Odessa harmonic banks, spawn pseudo-chaotic sequences when fed back to Lipsk, etc.

It can also operate standalone (without other Leibniz components), and act as an 8-output clock and audio frequency divider.

Since Erfurt is based on CMOS logic (no CPU!), it can be clocked at very high frequencies (exceeding audio rate) without any aliasing or frequency interference. It also features its own internal HF clock source that may be used with clockless data sources.

Lipsk facilitates the inversion of the individual bits produced by Drezno (or any other module connected to its input header at the back), and delivers the resulting code to its output header. Bit inversion can be manually controlled by pressing any of combination of its eight illuminated buttons, or it can be automated by patching gate signals into its gate input sockets. An active (5V) gate flips the state of the respective bit. If the button is active (bit already flipped), then the gate flips the bit again yielding double inversion (no inversion). The corresponding LEDs show the combined effect of both manual and gate actions. The bit processing logic is hardware-based, so there is virtually no latency, allowing the binary signals to be manipulated at extreme rates.

FEATURES

• Element of the universal subsystem for creating and processing analog signals in the 8-bit digital domain

• Suitable for CV and audio processing with no aliasing

• Bit inversion with manual and CV gate control

• No latency logic processing

Jena is a digital module that may be used as a flexible waveshaper for CV and audio signals, a wavetable oscillator, a Walsh function generator, or a rhythm generator. Jena is a new member of the Leibniz Binary Subsystem which operates on signals and voltages by manipulating binary 8-bit numbers. The Leibniz subsystem offers direct access to all individual bits of data which can be mixed and cross-patched (like in the popular circuit bending experimental technique, but without the risk of damaging your device). Please note that for analog inputs and outputs it needs to be paired with other Leibniz modules, such as Drezno. Complex chains will be possible as more components are added to the system. For example, you can use two Lipsk expanders (one before Jena, and another one after Jena in the chain) for unlimited patching.

Kamieniec is an analog signal processing module directly inspired by a range of classic phaser effect units from 1970s that helped to define entire musical genres. Most of these classic devices contained a fairly small number of phase shifting stages, but made up for that lack with tons of character! However, what was initially intended for guitars is not necessarily sufficient for synthesizers. Therefore, our intention is to preserve the classic sound as we transport it to a new tonal space while prioritizing flexible modular usability.

Just like many of the famous OTA-based phasers of the 1970s, Kamieniec sports four tunable stages. However, we’ve included two additional fixed stages so as to increase the number of notches, and ultimately offer two versions of the mixed signal (that may be used as a stereo pair) at the two outputs of the unit. While the general topology is similar to a certain very classic phaser pedal, the circuitry has been redesigned with modern components and low noise opamps to bring down the noise floor, improve the bandwidth, and offer a wider range of tuning. The feedback control can be set extremely deep, which results in a very high resonance that is capable of self-oscillation. This produces a unique sound otherwise unreachable for typical phasers, that can vary from subtle and creamy to utterly brutal and grinding. On top of that we’ve included switchable feedback paths, individual stage group outputs, CV inputs, built-in LFO, and daisy chaining ability to provide a comprehensive integration with a modular synthesizer system. For detailed description, please refer to the manual.

FEATURES

• Analog 4/6-stage phaser inspired by the 70s classics

• Simultaneous four and six-stage outputs

• Onboard voltage controlled wide range LFO

• Additional external modulation input

• Independent LFO output

• Two feedback modes

• TECHNICAL DETAILS

• Eurorack synth compatible

• 9hp, skiff friendly

• Current draw: +40mA / -40mA

• Reverse power protection

EXPANDABILITY

Unlike any other phaser module, multiple Kamieniec units can be chained together to achieve a more radical response with many notches. The general idea of chaining is to pass along the phase shifted signal to subsequent units before it is mixed with the original version in the last unit of the chain. This approach has a very different effect than plain cascading (connecting multiple phaser units in series), because a long chain of allpass sections yields a dense and uniform pattern of multiple notches, exactly like in a long phaser.
