Modulation & Random wave / cv generator with four connected triangle lfos / 4 HP ⇣ This LFO, harnessing four interconnected LFOs, offers a powerful tool for dynamically altering CV destinations in rhythmic patterns. Its synchronized modulation brings intricate rhythmic control to your creative endeavors. 1/3 key features 4x LFO Out 4x LFO Rate Rate Switch Skiff friendly Wrong polarity protection Illuminated Wave -Logo specs & downloads width: 4 HP depth: 28 mm power: 34 mA @ +12V / 25 mA @ -12V documentation videos description / manual The rate of each LFO may be adjusted with the dedicated potentiometers. Each LFO signal is supplied on the four outputs on the bottom side of the module. Depending on the potentiometer settings also slopes or square- wave s can be generated. Please refer to the demo video below. The fours LFOs are connected to each other creating an LFO-chain. If the first LFO reaches its highest value, the second LFO starts to rise. And when the first output reaches its lowest voltage, the second channel starts to decrease and so on. Each potentiometer controls the time it takes for the LFO to reach its maximum voltage, which also controls the time it takes to reach 0 volts for its inverted counterpart (1&3 and 2&4). Simultaneously the pots control the time the other two LFOs hold their maximum voltage level. Patching all LFOs into a VCO´s sound shaping functions you can create wave -like sounding effects that will repeat periodically. This module is very good for generating very slow cycles when the RATE switch is set to SLOW. Conversely, it can also generate fast cycles when the switch is set to FAST. The state of each LFO is being indicated by the illuminated letters W A V E on top of the module. Each letter will light up when its dedicated LFO outputs a voltage. 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.

Modulation & Random zeitreise / sample & hold, slew limiter and meandering cv generator / 6 HP ⇣ ZEITREISE is about the slow sequence of events that helps to take voltage on a journey through time. Its your perfect tool for creating slow and unpredictable parameter changes via control voltage. 1/2 key features Clock Generator Sample & Hold Slew Limiter 3x Slowly Meandering CV Noise Generator Internal Normalizations Skiff Friendly Wrong Polarity Protection specs & downloads width: 6 HP depth: 30 mm power: 60 mA @ +12V / 45 mA @ -12V documentation videos description / manual ZEITREISE is the German term for "time travel" and the time in this context is a clock signal that is set using the S&C CLK potentiometer on the top of the module. It´s rate can be as slow as 0.2 Hz ( approximately 12 bpm) and as fast as 21 Hz (approximately 1,236 bpm). This clock signal is sent to the internal Sample & Hold (S&H) circuit. A S&H circuit in modular synthesizers captures and holds voltage samples at specific intervals, usually triggered by an external clock, creating a stepped output that is useful for generating random or sequenced voltages for modulation. With ZEITREISE, any voltage applied to the S&H CV input is sampled, held and output to the S&H OUT socket with each clock pulse received, either externally via the S&H CLK input or, if this input is not patched, via the internal clock generator. You can reduce the voltage applied to the S&H CV input with the corresponding attenuator. The S&H output is forwarded to a slew limiter. A slew limiter smoothes or limits abrupt voltage changes and ensures controlled slew rates of the input signals, resulting in smoother transitions and curved waveforms for modulation and sound shaping. The amount of slew rate that attenuates the voltage changes can be increased by turning the SLEW IN potentiometer to the right. You can also feed external CVs, such as pitch voltages, into ZEITREISE via the SLEW IN socket. This allows you to create a portamento effect for tonal sequences. Below the S&H and slew limiter you will find three meandering CV outputs REISE EINS, REISE ZWEI and REISE DREI that slowly change their voltage levels (+0V to +8V). The voltages come from different stages within the same circuit. Take these voltages from the REISE outputs and reduce their voltage levels with the appropriate attenuators. Please note that the LEDS display the voltage levels before the attenuators to provide better feedback on the status of each REISE output. These voltages are great for slowly controlling external parameters such as sample playback points in samplers, filter cutoff frequencies or timbre and harmonics in oscillators. There is an additional output at the bottom, which supplies either the clock from the S&H CLK input (patched or normalized) or white noise. You can select one of these outputs using a jumper on the back of the module. ZEITREISE QUICK START GUIDE: ZEITREISE_QUICK_START .pdf Download PDF • 566KB prev Up next

Sequencer serial / shift register sequencer / 8 HP ⇣ Serial is a sequencer that generates random gates and voltages, allowing for seamless looping with a specified step length. It excels at quickly creating and cycling through random voltages while simultaneously producing up to 8 gates. 1/3 key features 8-Step Analog Sequencer Outputs 8 Gates and 1 CV Signal Sequence Randomly or Looped 4 Different Lengths Length CV External Clock Manually Add or Delete Notes/Gates CV Out Level Control Wrong Polarity Protection specs & downloads width: 8 HP depth: 30 mm power: 55 mA @ +12V / 21 mA @ -12V documentation videos description / manual The CLOCK input takes any voltage (CV & audio) and generates clock pulses according to a voltage threshold that can be adjusted by a trimmer on the back of the board. Turn it to the left to lower the threshold and increase the probability that low voltages will generate a clock signal. This clock is used to drive an internal shift register that reads a voltage level generated by an internal noise generator and synchronises it to the clock. The generated noise can also be taken from the NOISE output. If you plug something into the CV IN socket, this voltage is mixed with the noise source and locked to the sequence with every clock pulse. This way you can influence random notes with an external CV. When voltages are locked to a clock, a gate corresponding to that clock signal is generated and passed in series to the GATE OUTPUTS. In addition, a main trigger pulse is available at the PULSE socket. At the same time, the locked voltage is passed on to the CV OUT socket (e.g. to be routed to a 1V/OCT input of an oscillator). Adjust the level of this voltage with the AMOUNT knob. Use the ADD or DEL button to manually set or remove locked voltages in the sequence. You will notice that you can only add a note if you press ADD at the same time as a clock pulse. By pressing the LENGTH button, you can choose the step length of the sequence between 4, 6, 7 or 8 steps (the picture shows step 5, which was later changed to step 7). You can also change the length via CV. Please note that changing the step length can also lead to different output voltages at CV OUT, as it reads the voltages from different clock pulses. Use the RNDM/LOOP button to loop a sequence or create a random new series of voltages and gates. SERIAL QUICK START GUIDE: SERIAL_QUICK_START .pdf Download PDF • 532KB prev Up next

The LFO is internally linked to the Filter CUTOFF, modifiable using the CV1/TRI and SQU/CV2 knobs. These waveforms can be simultaneously utilized and reset via an external trigger. The automatic normalization of each LFO waveform disengages upon connecting an external CV source to the CV1 or CV2 input jacks. Adjust the LFO Rate using the designated potentiometer, with its speed indicated by a dual-colored LED. For waveform layering, a transistor-based 3-channel mixer is conveniently situated at the module's base. The mixer's sum directly feeds into the filter and is also routed to the MIX output jack. Precisely control input volumes per channel (VOL1-3) and collectively adjust them along with the filter INPUT potentiometer. prev Up next

Sequencer shikensa / cv and trigger sequencer / 12 HP ⇣ SHIKENSA is a 5-stage CV and trigger sequencer with some nifty features. 1/3 key features 5-Step Analog Sequencer Outputs 3 CV and 1 Trigger Signal 3 Different Track Lengths Internal Clock with Swing and Tempo CV External Clock, Reset and Hold ADD Input for Sequence Transposition LEVEL Control via CV for LVL OUT Wrong Polarity Protection specs & downloads width: 12 HP depth: 28 mm power: 55 mA @ +12V / 41 mA @ -12V documentation videos description / manual Shikensa offers the flexibility of an internal clock set via the tempo potentiometer or synchronization to an external clock. Its internal clock enables swing effects through the CLK CV attenuator, allowing tempo adjustment using external CV signals at the CLK CV input. Additionally, CV control permits sequence reset or hold actions. It is possible to change the length of the sequence from a maximum of 5 steps to 4 or 3 steps using a toggle switch. There are five sliding potentiometers that allow fine changes in CV values per step. There is a trimmer on the back of the PCB to adjust the maximum voltage from +5V to +10V. SHIKENSA has a total of four outputs. OUT is the standard CV output that you would connect to a 1V/OCT input of an oscillator. If you apply a control voltage to the ADD input, you can transpose the output of OUT. IN/CK outputs either an inverted signal of OUT or the internal clock signal (this can be changed by swapping two resistors). LVL OUT carries the same signal as OUT, but its level can be changed via CV. An attenuator allows control over the amount of change. When nothing is connected to the LVL CV input and the attenuator is turned up, an internal pitch envelope is added to LVL OUT, which is great for creating percussive sound sequences. These three outputs can be used simultaneously to change not only the pitch of an oscillator, but also other parameters such as waveshapers, filters or effects according to the sequence. TRIG provides a trigger signal that can be activated or deactivated per step. Five latching push-buttons on the bottom allow you to create rhythmic patterns. An LED indicates whether a trigger signal is being output. SHIKENSA QUICK START GUIDE: SHIKENSA_QUICK_START .pdf Download PDF • 716KB prev Up next
