The Coiler Multi-mode Filter and Rectifier packs an entire nest of sound-shaping features into a single 8HP Eurorack module. It's a two-pole state-variable filter based on a unique integrator design which stores energy in both inductors and capacitors depending on the frequency range. The transition region between the two components, and the saturation characteristics of the traditional OTA-based amplifiers, offer warmth and ever-shifting timbres in the midrange, along with hissing highs and slithering lows. This is a somewhat unpredictable filter.With simultaneous low-pass, band-pass, and high-pass outputs, the Coiler works well in traditional subtractive patches. But its built-in full-wave rectifier is also great for adding harmonics and distortion in patches from the other coast. When combined with low-pass, the rectifier allows the Coiler to serve as a basic envelope follower, for compression and external-signal patches. It's a lot of bite for the buck, and for the rack space.The MSK 009 Coiler VCF is available as a pre-built 6HP Eurorack module or a DIY kit.

North Coast makes the Eurorack four-knob utility mixer sound great again with this minimalist design featuring just six transistors. Where a conventional mixer would typically require at least five operational amplifier units each containing a dozen or more transistors, we cut the complexity and distill mixing to its essence. This is a new design made with current components and modern manufacturing quality; but its Class A amplifiers operate on principles that go all the way to the dawn of electronic signal processing.Suitable for both audio and control voltages, with bonus features that don't compromise the minimalist philosophy: positive and negative offset; simultaneous DC- and AC-coupled outputs; maximum gain a little over unity for when you need that extra push over the cliff. It can also function as a transistor distortion effect, by offsetting the signal until it clips and then using the AC-coupled output.Features:• High-quality potentiometers with bushings fastened to the panel for wobble-free operation; conductive plastic for smooth feel• All-new design, not a clone or imitation of anything else• Classic discrete-transistor design style; DIY kit ships with silicon 2N5088 transistors for a clean modern sound, easily modifiable to use other recent or "vintage" types• No ICs!• Through-hole for easy hand construction and maintenance• No compromises on build quality: real aluminum panel, not PCB material, with colour printing; nickel and gold plating on the circuit board; film output coupling capacitor; close-tolerance metal film fixed resistors.• Fully open design - no lock-inDIY-Kit-Type:THT-Kit-1.

North Coast's complex VCO is comfortable on a journey to the East or the West, while providing a stable foundation at home in any Eurorack. The module contains two triangle-core VCOs, each with four waveforms and standard V/octave control. As basic VCOs running independently these can be the heart of a traditional subtractive East Coast synthesizer. But the Middle Path's oscillators can also be used together, with or without sync, to drive its unique multi-output Gilbert-style sine shaper. The shaper, which can also take external input, offers wave shaping, distortion, folding, phase modulation including through-zero, and imitation stereo. These effects take the sound into West Coast territory.The design emphasis is on harmonious combination of simple principles. The exponential converter uses premium analog multipliers and a transistor array to ensure temperature stability without fiddly adjustments or hard-to-control "tempco" resistors; it should provide consistent tracking, and especially between the two oscillators, without needing to warm up. The triangle cores are intrinsically frequency-accurate without needing extra circuitry to compensate for reset time. The sine shaper includes our own novel quadrature modification which can be used to generate a stereo signal or in combination with other modules to create frequency shift effects. The sync circuit joins the oscillator cores in another way with a selection of soft and firm modes.Features:• High-quality potentiometers with bushings fastened to the panel for wobble-free operation; conductive plastic for smooth feel• Normalization to the Eurorack bus allowing it to receive pitch control without needing an input patch• All-new design, not a clone or imitation of anything else.

The Threetom Modular Doppio is a compact stereo amplifier, drive, and soft limiter module. Doppio helps complex and dynamic stereo sounds to find their place in a modular synthesizer context, where signals are hot, and headroom is extremely limited. Doppio does this by implementing a compact, yet flexible, soft-knee limiter. The limiter is specifically designed for eurorack levels and avoids the need for unnecessary make-up gain, resulting in a lower noise floor.Doppio offers three different gain settings (x1, x5, x21), and three different ratios (linear, drive, and limit). In addition to this Doppio has gain and volume knobs for more precise control. Different combinations of these settings cater to applications like saturating complex stereo signals without turning them into mush, end-of-chain limiting, and boosting line level signals to eurorack level, while still retaining enough oomph to also saturate them nicely. Finding the right settings is made easy by DOPPIO’s unique coffee-bean-shaped indicator lights.Even though Doppio’s architecture is stereo, that doesn’t mean it has no uses on mono signals: Either process two mono signals with identical settings, or chain the two channels to form a two-stage high-gain mono drive. Finally, it’s important to note that Doppio is DC-coupled and can also be used to process CV signals.In summary: Doppio is to your signals what a double espresso is to you – it makes you bigger and bolder – and you know you’re hooked when the withdrawal symptoms kick in.Features:• Three different maximum levels of gain: x1 (0dB), x5 (+14dB) and x21 (+26dB)• Three different soft-clipping modes: Drive mode, Off / linear mode and Limit mode• Caffeine knob for fine control over the gain applied to the inputs• Volume control for post-gain attenuation• Coffee-bean-shaped indicator lights make finding the desired settings easy• Reverse power protection• 4-layer PCB design with completely separate of audio supply rails and groundDIY-Kit-Type:SMD-Kit-1.

The Threetom Modular “Mixing Flask” is a utility mixer offering mix-bus limiting and a cornucopia of indicator lights integrated behind a unique chemical lab-inspired front panel.I designed Mixing Flask as a solution to my main three gripes with conventional utility mixers:• Mixing too hot is too easy, leading to hard clipping on the mix-bus. And even when there’s an indicator light to warn you when this is happening, there are no features to actively prevent it.• Utility mixers usually only offer unity gain, so when you have a weak input signal (like a MTM Radio Music), you’re out of luck• They’re nauseatingly boringMIXING FLASK provides solutions to these annoyances in the following ways:• I’ve implemented a soft-clipping limiting circuit on the mix-bus (inspired by DOPPIO). The highest setting prevents the mix-bus from hard clipping altogether in favor of warm saturation.• All inputs have a gain of +6dB allowing you to better equalize between volumes while maintaining a hot mix-bus output• The myriad of indicator lights and front-panel graphics make you feel like a mad scientist in your modular chemical lab. I bet you won’t find another utility mixer that makes mixing more exciting than Mixing Flask!Use cases:• Mix oscillator waveforms without the risk of hard-clipping• Mix CV signals while keeping an eye on what’s coming in and going out• Give a gentle boost to weak input signals (e.g. from a sampler module)• Have a utility mixer in your case that’s interesting to look at, and doesn’t bore you to death!Features:• Three different flavors of saturation on the mix output (hard clipping, soft/hard clipping, or soft-limiting)• Three inputs with up to +6dB of gain, and bipolar monitor lights• One mix output with three-stage bipolar monitor lights (signal present, signal nominal, hard-clipping warning)• Backlit chemical-lab-inspired front-panel graphicsDIY-Kit-Type:SMD-Kit-1.

Strakal Orsel is a tube distortion module that injects organic, vintage character into a modular setup. True to Touell Skouarn tradition, control labels use Breton terminology, while input and output are marked with arrows for clarity.The unit’s topology offers flexible tonal shaping: the Triodenn selector changes the left tube between pentode and triode operation, altering the core sound. The Boukl Retroaktiñ control combines a feedback engage switch with a level pot that ranges from subtle thickening to full, screaming self-oscillation. Gounid sets the balance between the first and second stages. Ampled governs the amount of saturation. A dedicated CV input, Enkas Modulañ, lets external control influence feedback and overall level even when feedback is not engaged.Beyond straightforward distortion, the circuitry produces rich secondary behaviors. With feedback pushed wide the circuit behaves as a powerful effect oscillator whose pitch responds to CV (not calibrated to strict 1 V/oct tracking). With feedback off and conservative level settings, the unit exposes its tube noise floor and can operate as a raw, characterful VCA.Features:• Tube distortion module• Exposes tube noise floor for characterful texture• Can function as a crude VCA• Compatible with 6j1P, 5654, 6AK5 and EF95 tubes• Boutique construction, made in Plougastel-DaoulasDIY-Kit-Type:SMD-Kit-1.

The Foldiplier is a 4 HP odd/even harmonics generator with 2 different oscillating feedback paths. The folding core of the design originates from the odd harmonics (middle)section of the Serge Wave Multiplier. But the Foldiplier adds voltage control over the symmetry and offset as well as a switch for feedback, jumper selectable between, a transistor based oscillating fuzz inspired by the Hemmo Bazz Fuss with a lot more low harmonic content and a passive oscillating half wave rectification circuit with more high harmonic content. When these feedback oscillations mix with an incoming waveform some unpredictable and unique nonlinear timbres can be achieved. The module can also be used as a no-input experimental oscillator with the feedback switch engaged. All diodes in the module are silicon.The Fold knob controls the amount of times the waveform is folded in on its self (indicated by the red led window below the knob). The C.V. knob below is an attenuator for incoming control voltage corresponding to the Fold jack(indicated by the red led window above the jack, it only responds to positive voltage). So, the Fold knob acts like an initial amount of folding depending on its position. For example, with the Fold knob fully clockwise you can get even more folds with a control voltage in at the Fold jack. The Offset knob controls how much positive DC voltage(0 to 5v, clockwise) or negative(0 to -5v counter clockwise) DC voltage(indicated by the led window above the Offset jack, red for positive, yellow for negative) injected into the waveform via the Symmetry knob. With the Offset knob position at noon(0v) there will little effect from the Symmetry knob. The Offset jack is expecting +5v to -5v with knob position at noon to scan through the positive and negative voltage. The Symmetry knob controls the amount of negative or positive offset voltage(dependent on the Offset knob) mixed with the waveform(indicated by the yellow led window above the Symmetry jack). If positive voltage is mixed with incoming waveform more folds will occur on the positive troughs of the waveform, likewise, when negative voltage is introduced more folds happen on the negative troughs. This part of the circuit can also be broken down by thinking of the Offset as a voltage controlled crossfader swinging between positive and negative voltages into a VCA controlled by the Symmetry knob and jack. When a voltage is present at the Symmetry jack the Symmetry knob becomes an attenuator. The Symmetry jack only responds to positive voltageDIY-Kit-Type:THT-Kit-1.

VC F3DB stands for Voltage Controlled Fixed Filter Feedback Distortion Bank. The simplest description is it’s an analog 16hp six band voltage controlled fixed filter bank. But with the additions of so much gain, clipping, feedback, and self-oscillation it becomes a very flexible and unique gestural sound sculpting tool capable of; graphic equalization over 6 octaves, multi-band distortion, spectral processing, crude vocoding, multi-frequency envelope following, self-modulation, and even as an instrument on its own. With no input it can be used as a pseudo chaotic “harmonic” feedback oscillator.The filter frequencies were specifically chosen to emphasize more ambiguous and dissonant intervals. Although the frequency bands are spread out over many octaves I purposely tried to leave out “3rds” besides a major 10th at the top frequencies to even out all the dissonance below. But the frequencies aren’t exactly equal tempered, so it’s relative. The bands roughly equate to F2, B3, F#5, C6, F7, A8.The design is based on the Moog 914 filterbank, which it borrows the frequency bands from. But this circuit uses active filters with opamps inspired by YU Synth opposed to passive cells using inductors on the original. The 88hz is a low pass -24db/oct and 7k is a high pass -24db/oct, the rest are -12db/oct band pass filters all with a Q around 4.The hard and soft clipping circuit on the input is fairly standard which appears in many different iterations of classic guitar pedals. But it has a lot of gain and can even boost line level signals. What makes it a bit unique is the feedback on the clipping circuit which needs to be turned on by the GFB(gain feedback) switch and the amount can be controlled by the Gain FB pot which can add some fuzz/bite to the signal depending on which clipping switch is engaged or at the extremes it will self oscillate from audio rate to LFO sort of clicking range. All the clipping stages in the module are using silicon diodes.Consult the Signal Flow Chart to the left for a rough visual breakdown of the controls,in/outs,normalizations, and optional settings for the module.Each band can also be muted by the top toggle switches or clipped(at the VCA) by the top slide switch which makes this design a bit different than other filter banks. As well as the overall feedback section(bottom middle) takes the sum/all bands out through a VCA(controlled by the feedback pot and FB CV) back to the input gain/clip circuit. and you can also tap into this using different sends/bands to the FB In jack to break the normalization. With this extra feedback “resonance” you can get more whistley and howly filter sounds kinda like the Serge res eq, which can also go into self oscillation.All CV ins are expecting +5v to open the VCAs (they wont respond to negative voltage), once you get closer to +8v or so it can clip the VCA regardless of the gain settings or clip switches. Output amplitude in high gain settings will exceed 10vpp and can get up to 20vpp. The envelope followers tend to stay around 0-5v out, but with clip switch active they can go up to 10v.Since this is a high gain module there can be bleed between the bands in certain configurations and situations. Also in high gain modes with higher frequencies the 2.8k and 7k bands can bleed a little with the VCAs closed.This is a highly involved DIY all through hole project.
