SEOK - PLUTNIK – Complex Dual VC-LFO [DEMO no talk]

video upload by SEOK synthesizers

"This is a pure modulation party in a small footprint. The Morph and Merge functions provide access to complex waveforms for a wide range of modulation. Distribute them across your rack via nine outputs.

Each LFO offers fast or slow cycling, with selectable square and triangle shapes. The fast cycles reach into audio territory at around 100 Hz, making it useful for percussive modulation and low-end movement. In slow mode, cycles extend up to ~35 seconds. With external negative CV, this can be pushed into the range of around 10 minutes.

Blend the LFO signals, or any external signals (including audio), in the Morph section. Or use the signals in the relational logic section, Merge, which opens up a wide set of derived waveforms by slicing, combining or rectifying. Pseudo waveshaping.

Designed and hand-built in Sweden."

SEOK synthesizers Introduces BOUNCE – One-Shot Event Generator Eurorack Module

video upload by SEOK synthesizers

"Bounce is a compact event generator built for percussive envelopes, bouncing modulations and rhythmic control. It creates trigger-driven one-shots with 8 distinct waveforms that can range from sharp clicks to rounded contours.

Repeat function with a ”bouncing ball” effect, making the bounces naturally fade within the cycle. Length, repeats and delay shape the result from tight hits to rolls, flams and clustered rhythms perfect for kick and bass.

Full CV control + inverted output. Designed and hand-built in Sweden."

"BOUNCE One-Shot Event Generator

This is a compact event generator built for percussive envelopes, bouncing modulations and rhythmic control signals.

Bounce creates trigger-driven one-shots with a set of 8 distinct waveforms selectable via the large control knob. From sharp, click-like hits to softer, rounded contours. This offers fast access to clearly different envelope characters.

Repeat function with a ”bouncing ball” effect, making the bounces naturally fade within the cycle.

The length control sets the length of the waveform while repeats add repetitions of the wave, and delay sets the time between those waves.

These features in combination makes it easy to move from single tight envelopes to rolls, flams, clustered impacts and creative rhythmic patterns.

All main parameters got CV-inputs. A dedicated inverted output adds instant polarity flip.

Background

We like techno. For us its about solid kicks with defined transients and a fundamental low end that moves air without collapsing the mix.

Bounce is built to be performative and work at the source. By shaping events, accents and repetitions already at the control stage – it lets the mix breathe and leaves space where it matters most. Perfect for basslines, drums and transients."

New SEOK Eurorack Modules - DRIPS, AT, M22, & ROTARIES

SEOK - DRIPS – Voltage Controlled Analog Filter [DEMO no talk]

video upload by SEOK synthesizers

via SEOK Eurorack Modules

DRIPS

A warm and bubbly 12 dB/oct analog Eurorack filter with dual voltage control of frequency. Low-pass, band-pass, and high-pass outputs in one compact 8 hp module.

With external signals, the filter stays soft, clean, and precise. Adding resonance gives a liquid acid tone (like a good filter coffee). When driven into self-oscillation, it produces sine waves perfect for deep bass, kicks, and percussive sounds.

An integrated VCA placed after the filter lets you shape both tone and dynamics in a single path – precise when clean, saturated and raw when pushed.

Raise the offset to move seamlessly from rhythmic sequences to heavy drones.

Background:
We wanted to build a versatile Eurorack VCF/VCA with a balanced function-to-HP ratio. For us, ergonomics are as important as function – it should feel intuitive and spacious around the core controls.

And since we’re from Sweden, we couldn’t resist adding a little warmth.

SEOK x ARTIST

A collaboration where an artist unleashes their creative madness on our gear. They dive in, explore, and shape their own workflow within a set time. In the end, they create something - be it a live improvisation, a track, or pure experimentation. We capture it all, letting the artist share their insights and experience along the way. Raw, fun, and authentic. The way good music should be made!"
