In this article, we explore the combination of the Sputnik Variable Waveform Generator, Xaoc Devices Erfurt, and more in creating excellent Eurorack builds. The Sputnik Variable Waveform Generator is a Buchla-inspired oscillator with five dedicated audio outputs and various animation controls. It offers a range of waveform manipulation options, such as wave folding, sawtooth animation, and overdrive.
The Sputnik Variable Waveform Generator features a discrete triangle core oscillator with a hard sync, which is a departure from the typical soft sync found in triangle core oscillators. With its 5 dedicated audio outputs (sub, pulse, sine, saw, and triangle), it allows for versatile sound shaping possibilities. Additionally, it includes animation controls like a built-in waveshaper, saw animator, and drive circuits with attenuation amount inputs.
When it comes to waveform manipulation options, the Sputnik Variable Waveform Generator offers specific controls for each waveform. For the sine waveform, there is a wave-folding slider that controls the level of wave-folding. The module also provides options for symmetrical and asymmetrical wave folding, allowing for a wide range of timbral possibilities. The sawtooth waveform features a slider that controls the position of additional saw waves for an animation effect. It offers options for double and triple sawtooth waves, allowing for unique and complex sawtooth animations. The triangle waveform includes an overdrive control, which produces standard triangle waves when the slider is down and full overdrive effect when the slider is all the way up.
In terms of modulation, the Sputnik Variable Waveform Generator offers various modulation inputs, including linear and exponential FM inputs with attenuators for precise control. It also features a V/OCT tracking FM input, allowing for accurate frequency tracking. With its hard sync function, the Sputnik Variable Waveform Generator can create interesting and varied sync effects when used with other waveforms.
Moving on to the Xaoc Devices Erfurt, this module is a versatile tool that can function as an 8-output clock and audio frequency divider, a binary counter, or a programmable digital oscillator. The Erfurt features an 8-bit register that holds its current state, which is an 8-bit number representing digital values from 0 to 255. This state is reflected by the 8 status LEDs on the front panel.
When operating alone, the state of the Erfurt changes by 1 at each impulse from the clock inputs, allowing it to count from 0 to 255 in a cycle (modulo 256). This provides frequency division options at various intervals, including divisions by 2, 4, 8, and up to 128. These divided clock outputs can be used to create complex rhythmic patterns in your Eurorack system.
By patching two different clocks to the inputs, the Erfurt alternately increases and decreases its state, resulting in a counter that counts with a rate proportional to the frequency difference between the clocks. This allows for even more rhythmic diversity and possibilities in your modular setup. A third clock can be patched to the reset input to shorten the sequence and create incomplete cycles, further expanding the rhythmic potential.
One of the unique features of the Erfurt is its integration into the Leibniz binary system, which allows it to interact with other Leibniz modules. When connected to a Leibniz data source, such as Lipsk, the Erfurt's state increases or decreases in larger steps depending on the data present at the Leibniz bus. This results in more complex patterns and opens up a world of creative possibilities.
The Erfurt can be utilized in various ways within your modular system. For example, it can be used as a phase input to a digital waveform table when connected to other Leibniz modules. It can also generate gate patterns, animate the spectrum of harmonic banks, and create pseudo-chaotic sequences when fed back to Lipsk. With its ability to be clocked at high frequencies, the Erfurt offers exceptional versatility and flexibility for sound exploration.
In addition to the Sputnik Variable Waveform Generator and Xaoc Devices Erfurt, we also discuss the Analog Computations AC3-1U, Erica Synths Black Stereo Reverb, and Jolin Ascolta modules in this article. These modules provide additional functionalities and enhance the overall versatility of the Eurorack system.
The Analog Computations AC3-1U is a module that performs simple computations of two analog signals, offering inversion, addition, average, and subtraction functionalities. It can be used for offsetting or transposing CV signals, creating new waveforms from VCOs, or combining modulation sources or axes from a joystick. The AC3-1U is a versatile tool for manipulating and processing signals within your modular system.
The Erica Synths Black Stereo Reverb is a powerful and versatile FX module based on a custom DSP engine. It offers selectable reverb sources, including Tape, BBD, and "dirty BBD" digital emulations, with three modes: Room, Hall, and Cathedral. With controls for room size, feedback, feedback tone, and stereo spin, this module allows for designing delicate and diverse reverberation effects. It also features CV control over various parameters and the ability to save up to 10 presets, making it a valuable addition to any performance-oriented Eurorack setup.
Lastly, we have the Jolin Ascolta module, a dual high-fidelity input preamp with envelope followers and peak detector outputs for each channel. This module is designed to amplify stereo line-level signals up to modular levels and extract envelopes and peak detector CV from any given signal. It is an excellent choice for integrating external audio sources, such as laptops, phones, dynamic microphones, external synths, and passive instruments, into your modular system. The Ascolta module features customizable internal normalization, audio-graded potentiometers, and a versatile power connector.
