North Coast's Transistor ADSR is a four stage traditional envelope generator for Eurorack synthesizers. With full control of four stages, it can shape percussion notes like an AR envelope, organ notes like an ASR, but also the complete range of acoustic-style and classic-synth notes which the simplified envelopes in some popular multi-modules just cannot handle. Use it in subtractive patches for amplitude or filter cutoff, or branch out into controlling other functions, like vibrato amount.At a svelte 6HP and only 33mm deep, the Transistor ADSR can fit in almost any rack. A Schmitt-trigger input allows it to trigger from slowly changing voltage sources, opening the door to special effects like gate delay when the MSK 012 is triggered by another envelope (or another MSK 012). Three timing ranges controlled by a rugged front-panel toggle switch cover a wide range of musical applications, with the fastest settings allowing the envelope to run well into the kilohertz range for audio-rate effects and signal conditioning. The smooth conductive-plastic potentiometers are a tactile joy to play and pay for themselves with increased lifespan.Features:• High-quality potentiometers with bushings fastened to the panel for wobble-free operation; conductive plastic for smooth feel• All-new circuit, not a clone or imitation of anything else• Classic discrete-transistor design• 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; poly film timing capacitors; 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. Innovative quadrature sine shaper offering through-zero phase modulation with a range of up to 1080°• Genuine AD633 and THAT320 chips in the exponential converter; sockets on all DIP ICs• Through-hole for easy hand construction and maintenance• Connectors between boards, and panel controls mounted on a board - no flying wires• No compromises on build quality: real aluminum panel, not PCB material, with colour printing; panel screwed solidly to both the PCBs and the pots and jacks, for maximum ruggedness; nickel and gold plating on the circuit boards; close-tolerance metal film fixed resistors.• Fully open design - no lock-in.DIY-Kit-Type:THT-Kit-1.

Crum Drum is a 4-voice drum machine with built in randomization and probability based sequencing designed by NYSTRÖMRhythms can be created and manipulated using the internal random sequencer or externally via MIDI USB. Press the beat button to generate new rhythms, adjust the probability to create continuous variations, and increase the randomness to modulate the sound of your beats! Generated sequences can also be sent out via MIDI USB and Crum Drum can also sync via analog clock in and out.The four voices of Crum Drum are Kick, Snare, HiHat and Bass (FM). There are 8 parameters knobs to sculpt the character of each voice allowing for wide variety of tones. It’s easy to create varied and organic sequences by adding modulation via the Probability and Randomness controls. Probability sets the chance that the selected voice will play per step of the sequence, while randomness increases the parameter modulation for each voice. The higher the randomness, the more each instrument parameter is modulated per step. Some of the instrument parameter controls have different behaviours depending on which voice is selected, so make sure to check the user manual for full details.Crum Drum features four global effects which are: Overdrive, Reverb, Delay and Swing. The delay-time is tempo synced and the subdivided differently dependent on the BPM.Power is provided via micro usb cable (not included)Features:• 4 instruments: Kick, Snare, HiHat, Bass• 8 sound parameters per instrument• Overdrive, Reverb, Delay & Swing• Send & Recieve Analog & Midi USB clock• Send & Receive Midi USB sequencing• Randomised and probability based sequencing

This is the V3 Version of HatzHi-hats are typically rich in complex, inharmonic frequencies that create a metallic, shimmering sound. Hi-hats rely heavily on noise components to create the "sizzle" effect. While analog circuits can generate white or colored noise using transistors or diodes, it's difficult to get the noise characteristics just right for hi-hats. Designing a noise source that consistently produces the right quality and amount of noise can require fine-tuning and careful component selection. Hi-hats need very fast attack and controlled decay to emulate the sharpness of a real cymbal. Achieving precise control over these fast transients is challenging in analog circuits.Hatz v3 is an analog circuit that includes 2 types of noise: "Metals" generates stable, high-frequency square wave oscillations that are essential for the metallic, bright sound characteristic of hi-hats. "Texture generates a unique, digital form of noise that has a slightly "stepped" quality, adding a texture that's not as smooth as white noise, but has a desirable grain.Independent envelopes for precise transient shaping and a bandpass filter for frequency control contribute to a complex, high-quality hi-hat sound. This design approach provides flexibility, realism, and sonic richness that elevates the hi-hat beyond basic analog percussion.Features:• Analog hi-hat module combining 2 kinds of noise heart ❤ complex (LFSR) noise and (LOGIC) noise metals• 2 pole filter for each individual channel with CV• Vintage drum machine accent style• Choke switch• Linear and exponential fall selection in both channels• Open hat decay control with CV input• Decay control for the closed hat• Hold input for manual envelope opening via gates and CV• 2 LED indicators• Accent input with level/accent attenuatorDIY-Kit-Type:SMD-Kit-1.
