Oscillator hh / analog hi-hat and noise generator / 4 HP ⇣ HH is a very simple, but handy little module that completes any modular drum rack. 1/3 key features Analog Hi-Hat and Noise Generator Internal Decay Envelope Internal VCA CV Control over VCA Offset CV Attenuator Adjustable Noise Colour: Brown, Pink, White Illuminated ST Modular Logo specs & downloads width: 8 HP depth: 28 mm power: 35 mA @ +12V / 25 mA @ -12V documentation videos description / manual HH is an analog Hi-Hat and Noise generator with an internal VCA and decay envelope. The Module can be triggered by a trigger signal at the TRIG Input. Using the DECAY potentiometer you can open and close the Hi-Hat. The ST Modular logo will flash according to the decay envelope. This may also be voltage controlled with any CV signal at the CV input. The voltage changes the internal VCA offset, but does not affect the decay envelope. The incoming voltage can be attenuated using the dedicated attenuator potentiometer. An LED indicates the current state of the voltage. Additionally you may also change the colour of the noise being generated with the COLOUR pot. Fully counter-clockwise the noise will equal Brown Noise with reduced high frequencies. At noon it will sound like Pink Noise, which is a bit louder at the low-frequency end of the spectrum, and softer at the high end. Almost fully clockwise it will be White Noise, broadly spread across the sound spectrum, sounding like a waterfall. Fully clockwise the noise will be boosted on all frequencies to have a more present noise spectrum. prev Up next

KRAKONG is a duophonic generative synthesizer with a sequencer per voice, FM crossover modulation, an additional random modulation sequencer, one multimode filter with VCA, a buffered multiple and a resettable LFO. The design includes a collection of manual controls and connections for patching and CV control. "Krakong fits seamlessly into a series of well-known generative semi-modular synthesizers. It invites you to lose yourself in hours of sound design and keeps surprising you with new sounds and sequences." MAIN FEATURES KRAKONG is a duophonic generative synthesizer with a sequencer per voice, FM crossover modulation, an additional random modulation sequencer, one multimode filter with VCA, a buffered multiple and a resettable LFO. The design includes a collection of manual controls and connections for patching and CV control. It fits into a standard Eurorack case with at least 80 HP (3U). Each of the unit's two voices consists of a triangle and a square wave oscillator, a shift register sequencer, a decay envelope generator and a filter-based gate. In addition to the two synthesizer voices, which can be manually distributed in the stereo field, a third ring-modulated output of the two voices can be mixed to the main output. The tempo of all sequencers is determined by a clock generator, which can be controlled internally or synchronised externally to any voltage (audio and CV). This musical instrument has a complete structure that allows for a wide range of sonic possibilities, from rhythmic drum patterns and tamed sonic chaos to textural and rough synth-sounds. The essence of this unit lies in the exploration of the interplay between the elements of the synthesiser, using the three sequencers and filters, manual controls and modulation patch points. It can be powered by a standard Eurorack PSU or a small ST Modular PSU PCB that can be built separately.

Oscillator chiasso v2 / analog fm drum synth / 14 HP ⇣ CHIASSO V2 stands as an exceptional oscillator, perfect for generating dynamic Techno sounds that consistently captivate through each knob adjustment. In its V2 iteration, it retains the same exceptional sound foundation found in V1. However, V2 introduces innovative enhancements like CV decay inputs and an added noise source for oscillator A, promising even more sonic possibilities. 1/3 key features Two Analog VCOs Two LFOs SQUARE and TRIANGLE Waveforms for OSC and LFO Cross Modulation CV Decay Fade Potentiometer to adjust the Oscillator Mix Trigger and Pitch Normalization Wrong Polarity Protection specs & downloads width: 14 HP depth: 28 mm power: 55 mA @ +12V / 35 mA @ -12V documentation videos description / manual The module has two oscillators that can generate square or triangular waveforms that you can seamlessly crossfade with the WAVE potentiometers. Each oscillator has its own CV decay envelope, a pitch potentiometer and can be triggered with a trigger signal patched to the left TRIG input as well as individually via the left and right TRIG inputs. A fade potentiometer offers the possibility to manually fade between both oscillators to adjust the mix. Noise can be added to the left oscillator A to make it a little dirtier. There are PITCH CV inputs with attenuators for each voice which, although they don´t track exactly 1 V/OCT, are very useful for changing the mood of each signal to create very organic and moving sounds. The audio output of each side is normalised to the PITCH CV input of the opposite side. The left side is connected after the VCA and the right side before the VCA to achieve different types of cross-modulations and to apply modulation according to incoming trigger signals. In addition, the module has two individual LFOs with square or triangular waveforms that can be fed to the oscillators for further frequency modulation synthesis. Both LFOs have an attenuator to adjust the strength of the modulation and a RATE potentiometer to change the speed of the LFO cycle. The signals of the two oscillators are mixed and output at the OUT socket. prev Up next

Mixer & VCA cuerly / 3-channel stereo mixer with cue / 6 HP ⇣ Cuerly is a compact 3-channel stereo mixer with cue functionality, allowing you to pre-listen to signals before sending them to the main mix. It’s the perfect mixer for live performances in a small Eurorack setup. 1/4 key features 3 Stereo-Channels Level Control per Channel Cue Buttons for Pre-Listening Heaphone Output Headphone Level Control Mix to Headphone Control Max. Gain +20dB Wrong polarity protection specs & downloads width: 6 HP depth: 40 mm power: 43 mA @ +12V / 35 mA @ -12V documentation videos description / manual Cuerly features three stereo channels, each with independent level control. You can connect a stereo signal to any of the three inputs: IN1, IN2, or IN3. The level of each channel is adjusted using the corresponding VOL1, VOL2, and VOL3 knobs. Mono signals can also be processed by patching a cable into the left input, which will automatically normalize the signal to the right channel. The final mix is sent to stereo headphones via the TRS PHONES output. You can control the headphone volume using the VOL HP potentiometer. To preview a signal, simply press the corresponding cue button. The cued signal is removed from the main mix and routed exclusively to the headphone output. The VOL1, VOL2, and VOL3 knobs continue to function as level controls, even when the signal is cued through the headphones. The LEDs serve as level indicators for the cued signal only. For direct comparison, turn the MIX TO HP knob to the right. This routes the main mix to the headphones along with the cued signal, allowing you to compose and patch new sounds while still monitoring the main output - without needing to remove your headphones. You can cue any combination of the three channels. If all three cue buttons are active, no audio will be sent to the main output, and the signal will be routed only to the headphones. Additionally, the cue buttons can function as mute controls for the main mix. Cuerly offers a maximum gain of +20dB, with independent gain adjustment for each of the six inputs. Gain levels can be fine-tuned using the trimmer potentiometers located on the back of the module. Cuerly is designed specifically for live performances, where sounds are improvised and created on the fly. Its compact size makes it the ideal addition to your small performance case.

Effects singer / feature-rich delay with extensive parameters / 8 HP ⇣ Probably SINGER is one of the best equipped DIY PT2399 Delays available. It is the consequence of years of development of other delay effects such as DELAY V2 and GRITZNER and now combines new and old functions in one module. Why another PT2399 Delay? Well, because the PT2399 is a very special kind of delay with its own and very unique character we all love and we want CV control over most parameters. In contrast to DELAY V2 and GRITZNER, SINGER was made to explore the boundaries of the PT2399 chip and is able to create all sorts of crazy delay, glitch and noise sounds. It is rather specialized on short delay times, but can create some really nice delay and feedback craziness. 1/4 key features Analog Delay CV Control over most Parameters Two Inputs Internal LFO WET Output Wrong polarity protection specs & downloads width: 8 HP depth: 45 mm power: 95 mA @ +12V / 45 mA @ -12V documentation videos description / manual SINGER has two audio inputs IN A and IN B, whereas IN B includes a high pass filter that attenuates frequencies below 320Hz. Especially for effect sends it is helpful to only introduce a high pass filtered delay effect to the mix. You can switch between IN A and IN B by using the A/B switch (switch MAN / LFO set to MAN) or by introducing a CV gate signal to the A/B GATE input jack. When the CV gate signal is high, only IN B will be routed to the delay circuitry indicated by the IN B LED. It is also possible to switch between both inputs using the internal LFO (switch MAN / LFO set to LFO). This way you can create some really unique delay cascades using two different audio signals. The DELAY TIME can be changed with the large DLY TME knob. The range is set to be too large for the PT2399 chip to handle. Consequently turning the knob from 2 o´clock on clockwise will create crazy glitches and noise artifacts. Cleaner delay times can be achieved by settings from 7 to 12 o´clock. The delay time can be changed via CV at the TIME CV input jack. A dedicated DLY CV attenuator let´s you decrease the amount of CV that is being applied. Additionally an internal LFO can control delay time if nothing is patched into the TIME CV jack and the DLY CV knob is turned to the right. The LFO rate can be set with the LFO RATE potentiometer and the LFO cycle can be reset by a CV gate or trigger signal that is patched to the LFO RESET input jack. You may choose to use a triangle or square wave LFO with the help of the TRI/SQU switch. The LFO is normalized to delay rate and feedback via the dedicated attenuators if nothing is patched to the corresponding CV input jacks. The LFO rate LED only indicates LFO waves controlling delay rates after attenuation. The LFO is also normalized to the A/B input switch if the MAN / LFO switch is set to LFO. A DRY/WET potentiometer sets the amount of delay effect that is applied to the OUT jack. On top the level of the wet signal can be changed with the IN attenuator. Hence if the DRY/WET pot is fully clockwise and the IN attenuator is fully counter-clockwise, no signal is audible at the OUT jack. FEEDBACK may be changed with the help of the FEEDBACK knob and can also be controlled via CV at the FDBK CV jack and the dedicated FDBK CV attenuator. If nothing is patched to the FDBK CV jack you can also route the internal LFO to control the feedback amount if you turn the FDBK CV attenuator to the right. VCA CV provides the opportunity to control the level of amplification of the wet signal via control voltages such as an envelope or an LFO. The WET output supplies the pure delay signal at any time.
