Notes: SetonixSynth Ancient Scroll Voltage-Controlled Decay Envelope

The SetonixSynth Ancient Scroll is a Voltage-Controlled Decay Envelope for 1U modular format. In a small 10hp package, the Ancient Scroll delivers a snappy and musical envelope with its Output level switchable between 0-5V and 0-8V for use with any VCA or effect.

Critically, this envelope features both manual and voltage control over its Decay time, making it perfect for "intelligent" percussion, hi hats, and morphing West Coast bongos.

If you're looking for a small yet voltage-controllable 1U envelope to relieve some burden from your larger specialty modulators, the Ancient Scroll is a fantastic option!

Width: 10 hp (Intellijel 1U format)

Peak Current Draw: 25 mA @ +12V, 20mA @ -12V
Time Range: 6 mS - 15 seconds (approx)

Notes: SetonixSynth Arcane Knowledge Vintage VCA / Overdrive

The SetonixSynth Arcane Knowledge marries two classic audio circuits to create a "utility flavour" module. First up is a discrete transistor core VCA stage similar to those found in very early modular synths: not the cleanest or most precise amplifier, but rather full of harmonic richness and color to bring a little kick to those squeaky clean waveforms.

This VCA may be used on its own or through the switchable Drive circuit, which slaps a high-gain Tube Screamer-style soft clipping overdrive stage on the audio signal. Unlike the Tube Screamer, however, the Arcane Knowledge's drive stage uses different diodes in the forward and reverse position, creating asymmetric clipping with more emphasis of even order harmonics. Using the rear trimmer, this stage can be configured to give the VCA output signal anything from a tasty boost to fully crunched sonic mayhem.

For those looking to liven up their sound, sometimes the old ways are best. Enlighten yourself: it's the Arcane Knowledge!

Notes: The SetonixSynth Boing! is a Light Dependent Resistor-controlled low pass filter. It takes its primary inspiration from ultra-simple yet delightful passive Vactrol Low Pass Gate modules such as the PassiVac and DPLPG, but adds JFET transistor input and output stages and an active LED control circuit, thus enabling the introduction of wonderful Feedback and Trigger functions, LED brightness offset, and a second filter stage. Combined, these features allow for incredible variable-cutoff overdrive and low pass filter sounds in addition to bouncy LPG Bongos and more.

Notes: The Noise Complaint! is a passive utility module which provides a bank of four passive attenuators which can be used with audio or CV. Each of the Noise Complaint’s four inputs are normalized (left to right), so that with nothing patched to a channel’s input it can be used as an attenuated mult, distributing up to four versions of one input signal and opening up myriad control possibilities, such as use of Channel One as a Macro control over the three other outputs. Channels 1-3 also have muting switches for performance-friendliness and preservation of settings.

The Noise Complaint! has proven to be a very useful module for attenuation of all kinds, and adds a nice-feeling, sturdy set of performance controls to what is often a cluttered rack full of densely-packed jacks and tiny attenuation knobs.

Current draw: 0mA @ +12V, 0mA @ -12V (Passive)

Notes: SetonixSynth Sands Of Time 1U Filtered Noise Source Module

The SetonixSynth Sands of Time is a compact 1U noise source which contains two separate noise circuits: a transistor-based analog noise generator similar to those used in many classic modular synth systems of the '60s and '70s, and a CMOS logic-based fixed oscillator bank as found in some of the great drum machines of the '80s, particularly of the TR series.

Either or both of these noise sources may be routed to a sweepable active bandpass filter, perfect for shaping the noise into many different "flavors," from low-frequency rumble, to chest-thumping midrange snare source, to hissing raw hi-hat noise and everything in between.

In a very small package, the Sands of Time provides a full palette of audio frequencies and Noise-like sounds which are useful in many popular patching techniques, especially analog drum patches and "Noise Walls" along with the generation of pseudo-random voltages for use with Sample & Holds, slew generators, and more.

Though it demands just 10hp of 1U rack space, the Sands of Time is still a useful and diverse noise source with some "oomph," a crucial yet often overlooked addition to any setup or patch.

Notes: The Solar Gravity from SetonixSynth and Tidbit Audio is an analogue vactrol-based VCA designed to bring the lovely response of optocouplers into the realm of clean, performance-based Eurorack VCAs. Starting with this simple concept, the Solar Gravity utilizes some neat active circuitry to significantly reduce the bleed inherent in vactrol-based VCAs and to provide the user with lots of control over the level, direction, and response of incoming control voltage.

Though it's primarily designed for use with audio signals, the Solar Gravity can also be used to control the level of CV such as envelopes or stepped voltages with a unique vactrol response through its DC-coupled input.
