Casting spells on every boring clock signals, The Time Wizard got a bag full of arcane time-warping tricks. All his magical feats are based on 6 dividers with selectable division factors and 4 switches providing 81 routing variations.This module's occult powers have been harnessed to easily clock and reset other sequencers with odd time signatures, provide weird clock division/multiplication ratios, and create complex poly-rhythmsFeatures:• Sextuple clock divider divided in two sections A and B• Dedicated potentiometer acting on the division factor for each divider• Clock multiplying and weird div / mult ratio abilities for the first section, first section incoming clock can be multiplied by 3 or 4, allowing to get easily triplets from a 16th clock or mult / div association as x4 / 7• Independant clocking or divider association abilities for the second section, so B5 and B6 can get their clock in internaly from B4. For example, associating B4 = /7 and B5 = /16 provide a hit at each clock begining of 4 bars with a 7/4 time signature• Auto-reset available for the first section or the whole module, the autoreset is provided by B6• Additional logic functions for divider A2 : A2 output can provide the following functions : A2 AND B5 or A2 OR A3• Jumper on the back for Trigger or Gate selection for B5 and B6• User replaceable firmware chipDIY-Kit-Type:SMD-Kit-1.

The Battering Ram is a bass drum synthesizer based on an original design by Marc Nostromo. This module offers precise control over various parameters, including decay, tuning, depth, click amount, and drive. These controls have been thoughtfully mapped to provide sweet spots at every combination of potentiometer settings. The drive section can seamlessly transition between two distinct wave-shaping modes, ranging from smooth drive/compression to hard-clipping distortion for core music lovers. For smooth modular integration, there's an additional output that mirrors the amplitude envelope or its inverted shape.The module also boasts other convenient features, such as storing and recalling potentiometer settings, a 3-pole high-pass filter, and the option to use gates instead of triggers. Despite its compact size, the Battering Ram delivers a diverse range of bass drum sounds, from long sub-bass drums to aggressive techno kicks.Features:• Kick drum module based on an original design• Expansive sonic palette spanning from 808-inspired sub-bass to assertively distorted kicks• Dual drive options: a subtle fold for gentle saturation or a high-gain distortion with clipping• Amplitude envelope output with inversion switch• CV control over different parameters including a V/oct pitch input• Dynamic phrasing through velocity input.• Pitch locking functionality transforms the tuning potentiometer into an octave switch• Gate mode• Switchable 30Hz 3 poles high pass filter• Store and recall panel parameters feature• Select bus compatibility with 16 presets• Djtechtools rubber injected knobs• Skiff friendlyDIY-Kit-Type:SMD-Kit-1.

Mal-2 is a random signal generator mainly intended as CV modulation source. It has 2 modes of operation to provide you with smooth random goodness. Imagine Eris herself lends you a third hand to keep your patches interesting.In the first mode the CHANGE knob morphs from a cubic interpolated (sine like shaped) random signal to a random walk function that could make a wallstreet broker delirious with joy.In the second mode the CHANGE knob sets the self similarity. On the minimum setting the signal is completely random. On the maximum setting the random sequence is locked to a repeating, identical 8 step sequence. In between the sequence seamlessly morphs to new shapes over time.This gives you a random CV where you can shape the bounds in which the chaos unfolds and goes far beyond a slew limited white noise.DIY-Kit-Type:THT-Kit-1.

Horrorscape Synthesizer - sculpting feedback into sonic art!Audrey II is a horrorscape synthesizer designed for fearless exploration of feedback. Unpredictable yet compelling, it transforms chaotic sound into immersive soundscapes. From deep, haunting drones to screeching, otherworldly tones, Audrey II is a sonic beast like no other.Feedback Synthesis?What is feedback, really? It’s that magical moment when sound loops on itself, evolving into something wild. With Audrey II, we’re taking feedback to the next level using Karplus-Strong synthesis—a fancy term for turning short bursts of noise into rich, self-sustaining tones. Think digital strings, but way cooler.Digital WitchcraftSome say analog is the only way to get that sound… We were surprised too when we heard the first burst of noise coming through our headphones. That warmth, the grit, the unpredictability—it was all there. But here’s the twist: Audrey II is 100% digital, running on the almighty Daisy Seed platform.Built from the ground up to emulate analog chaos, digital bits power every nuance of Audrey II’s feedback, distortion, and reverb-drenched echoes. It’s pure digital magic that doesn’t just imitate analog—it embraces and amplifies it. What you hear isn’t just a close approximation; it’s a whole new breed of sound that pushes digital synthesis into uncharted territory.Pristine SoundPowered by the Daisy Seed microcontroller, Audrey II delivers 96kHz / 24-bit audio with the speed of an ARM Cortex-M7 at 480MHz. Equipped with 64MB of SDRAM, it handles complex feedback, drones, and effects seamlessly, pushing digital synthesis into rich, analog-like territory.The Signal Flow01. Karplus-Strong Synthesis & DistortionThe signal begins with Karplus-Strong synthesis, a method of string synthesis that creates resonant, droning tones—adding layers of harmonics to emulate organic vibrations, while feedback and distortion weave in raw, aggressive edges.02. ReverbNext, the signal passes through a rich, spacious reverb, allowing the drone and feedback to bloom, creating haunting and immersive atmospheres.03. FiltersFollowing the reverb, Audrey II utilizes high-pass and low-pass filters with a body control to shape the sound further, revealing hidden overtones and harmonic textures that can add either warmth or an eerie sharpness to the feedback.04. Tape Delay EmulationFinally, the signal reaches a tape delay emulator that further degrades and expands the sound, adding layers of movement, modulation, and a classic tape echo feel that’s both nostalgic and unpredictable.05. Stereo OutputTo top it all off, Audrey II’s stereo output widens the soundstage, creating a sense of depth and space that immerses you in rich, layered textures. With stereo feedback flowing through the chain, each element takes on new dimensions, allowing you to push the boundaries of sonic space.Driven & Open SourceAudrey II is a collaborative project born from the Synthux Academy community, where music technology enthusiasts, designers, and engineers come together to push creative boundaries. Developed by Nick Donadson from Infrasonic Audio and designed by Roey Tsemah, founder of Synthux Academy, Audrey II embodies the spirit of exploration and innovation that drives this community.Audrey II’s firmware is available on our GitHub, inviting anyone to dive into the code, make modifications, or build upon its foundation. This open-source approach empowers makers not only to experiment with Audrey II’s sound but to shape its future, contribute enhancements, and share discoveries with the Synthux Academy community. Audrey II is a testament to the creativity that can emerge from collective knowledge and a shared passion for instrument design.Features:• Karplus Strong synth engine• Reverb amount• Reverb size• High and low pass filters• Tape delay emulation• Stereo out• Built on the Daisy Seed• Open sourceDIY-Kit-Type:THT-Kit-1.
