Modulation & Random influencer / multiple random cv generator / 14 HP ⇣ INFLUENCER offers a versatile collection of CV tools and creative unpredictability, divided into five distinctive sections, each serving a distinct purpose. With an array of modulation sources and an added touch of uncertainty, INFLUENCER stands as your comprehensive CV powerhouse. 1/3 key features 5x CV Generators Internal Clock & LFO CV Fall Envelope Sample & Hold/Track A/B Comparator Smooth Random CV Noise Out Input Normalisations specs & downloads width: 14 HP depth: 28 mm power: 110 mA @ +12V / 65 mA @ -12V documentation videos description / manual The TOP SECTION is the VC INTERNAL CLOCK and TRIANGLE LFO. The rate of the clock and LFO can be controlled by the RATE knob or CV. The clock signal is normalised to the trigger input of the FALL section. The TRIANGLE wave at the WAVE socket is also routed to the WAVE/RNDM SWITCH of the FALL section. When the switch is in the upper position and the attenuator is turned to the left, the wave will affect the FALL length. In the lower position, the FALL CV is slowly randomised. The SECOND SECTION is a FALL ENVELOPE GENERATOR. It can be triggered internally or externally and its fall time can be controlled by the FALL TIME knob or by CV. An inverted version of the fall output is also available. The THIRD SECTION is the SAMPLE & HOLD section. In one mode, it can sample and store a voltage from the FALL CV socket and output it at the SP OUT socket when the gate at GATE is high (Sample & Hold). In another mode, it can pass through the incoming voltage when GATE is high. It then samples and stores the last voltage applied when GATE is low (Sample & Track). The modes are selected by the MODE switch. The STEPPED potentiometer controls the level of the incoming CV signal. Internally the CLOCK is normalised to the GATE input. The CV input can be fed by an external signal, an internal SMOOTH RANDOM CV or by internal NOISE. Please note that this section may produce noise bursts in Sample & Track mode. The FOURTH SECTION is an AND / OR COMPARATOR that compares two mixable inputs and outputs the MAXIMUM CV and MINIMUM CV of both. It also generates a GATE at B-GATE if IN B is greater than IN A. Note that MIN LED barley flashes with low CV levels.The LAST SECTION is a DUAL SMOOTH RANDOM CV GENERATOR. It provides a constantly changing CV at SMOOTH I and SMOOTH II, slowly meandering in about 60 second cycles. The SMOOTH CV input will affect the SMOOTH outputs in unpredictable ways, sometimes not at all. Internally there is another SMOOTH RANDOM GENERATOR which is normalised to the RNDM switch position of the FALL section, the CLOCK CV and the SOURCE switch of the SAMPLE & HOLD section. Like the others, this SMOOTH GENERATOR may or may not be influenced by the INFLUENCE input. NOISE OUT allows access to the internal NOISE GENERATOR. You could also use the module as an OSCILLATOR.

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

Effects clipping cat / vactrol distortion with diode clipping & lpg / 4 HP ⇣ CLIPPING CAT will make your sounds meow! It's a Vactrol-based distortion that will easily cram a lot of filth and grit into your tone. From sine waves to kick drums, this cat won't miss a scratching post! 1/3 key features Vactrol Distortion Diode Clipping Soft & Hard Clipping „Diode Playground“ for Easy Replacement of Soft Clipping Diodes Vactrol LPG Skiff friendly Wrong polarity protection specs & downloads width: 4 HP depth: 30 mm power: 20 mA @ +12V / 20 mA @ -12V documentation videos description / manual Based on the passive and very simple WORKMATE CLIPPING CAT, this souped-up 3U module now features three main controls. GAIN determines the amount of distortion applied to your signal. LEVEL decreases the signal level that is fed into the circuit and the CAT/NO CAT switch activates or deactivates the additional diode clipping function. You can choose whether you want hard (CAT) or soft clipping (NO CAT). Depending on the diodes you solder in, the clipping behaviour and sound will change drastically. CLIPPING CAT will only blink and meow if you set the switch to "CAT" and have set a good amount of gain. The amount of gain can also be voltage controlled using the CV GAIN input socket. Each incoming CV signal can be attenuated with the corresponding potentiometer. The overall gain range can be adjusted using a trimmer on the back of the board. This CV functionality also allows CLIPPING CAT to be used as a low-pass gate with the smooth vactrol-based behaviour we all love. Another trimmer allows the circuit to be optimised for LPG or distortion purposes. To simplify the exchange of diodes for soft clipping mode, there is a "diode playground" on the back of the board where you can easily exchange through hole diodes . Feel free to experiment with different types of diodes and discover novel distortion sounds. Purr! prev Up next

Three 1 to 4 Buffered and Attenuverted Multiples & Voltage Source lange anna & anna´s langer arm / three 1 to 4 buffered and attenuverted multiples & voltage source + sattelites ⇣ LANGE ANNA might just be the lengthiest treat in the DIY Eurorack universe! It sprawls across a substantial 84 HP, essentially taking up the bulk of standard cases. The core idea is to effectively carry CV and audio signals throughout the width of a Eurorack case. The satellite modules, ANNAS LANGER ARM, offered in both 3U and 1U format, play a crucial role in further distributing signals across your case. key features 3x 1 to 4 Buffered Multiple Attenuverter per Channel Constant Voltages Normalized to Inputs LED Indication Optional Satellite Modules with Summed Output in 20HP 1U and 4HP 3U Wrong polarity protection Skiff friendly specs & downloads width: 84 HP / 20 HP / 4 HP depth: 28 mm power: 65 mA @ +12V / 50 mA @ -12V documents description / manual This buffered multiple has three channels that multiply each signal to four outputs. For each channel there is a bipolar attenuator to adjust the signal level and polarity. LEDs above and below each output indicate whether a positive or negative signal is present. When nothing is connected to an input, a constant voltage is normalized to the inputs. There is a switch to select the maximum voltage of +10V or +5V. By utilizing the attenuators, you have the capability to employ these voltages for the manipulation of various other module parameters. ANNA'S LANGER ARM was conceived for journeys to distant destinations. Its purpose is to transport signals to unexplored corners, places within your cabinet untouched by any other CV or audio signal. This module establishes a direct link with the LANGE ANNA and eliminates the need for a separate power connection. It offers an additional multiple output per channel and a cumulative output that combines signals from all three channels. The module can be positioned at a considerable distance from your LANGE ANNA unit, effectively spanning the entire width of your modular setup. LEDs positioned above and below each output serve to indicate the presence of positive or negative signals, simplifying the task of assigning an output to a corresponding LANGE ANNA input. Theoretically, you can add as many satellites to LANGE ANNA as you want, as each module has its own buffers. However, there may be some negative side effects when transmitting the signals over very long distances. videos Up

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

Oscillator cyllene V2 / classic analog vco with three sub-octaves and internal FM / 10 HP ⇣ The Cyllene module is a fully analog oscillator that stands out with features like three sub-octave layers and internal frequency modulation. It's a versatile sound source designed to deliver rich and complex tones for your modular system. 1/3 key features Classic Analog VCO 4 Waveforms: PULSE, TRIANGLE, VARIABLE WAVEFORM, SAWTOOTH (MOD) 1V/Octave tracking Internal VCA Pulse Width Modulation with Attenuator Internal Frequency Modulation via Modulation Oscillator Up to 3 Sub-octaves Attenuator for each Sub-octave Wrong Polarity Protection specs & downloads width: 10 HP depth: 28 mm power: 26 mA @ +12V / 19 mA @ -12V documentation videos description / manual Cyllene offers four waveform options : pulse wave triangle wave variable waveform (which blends between sine and pulse via trimmer on the back) modulation sawtooth wave. You can select the active waveform using the SELECT knob. This can be done manually or controlled via CV input. An LED shows which waveform is currently selected. To tune the oscillator, use the COARSE knob for broad pitch adjustments and the FINE knob for precise tuning. The V/OCT input allows Cyllene to track pitch from sequencers or keyboards accurately across at least five octaves (1V per octave standard). For added depth, you can blend in up to three sub-octaves with any waveform: The BASE function adds a pulse wave three octaves below the current pitch. The SUB section introduces two additional sub-octaves: one and two octaves below the main pitch. Use the SUB -2 / SUB -1 control to mix between them. In the center position, both are equally present; turning fully left or right isolates one sub-octave. A NOISE control lets you mix in white noise to enhance texture and add grit to the signal. Cyllene also features internal frequency modulation (FM) . Use the MOD FREQ knob to adjust the pitch of the internal modulation oscillator, and the MOD AMT knob to control how strongly it modulates the main waveform. The MOD SYNC switch allows you to unlink the modulation oscillator from the V/OCT input for more experimental FM tones. The pulse width of the pulse wave can be shaped manually with the PULSE WIDTH knob or modulated externally via the PWM CV input with its dedicated attenuator. Lastly, Cyllene includes a built-in VCA , which lets you control the oscillator's volume using an external envelope or control voltage, eliminating the need for an extra VCA module and saving valuable rack space.

Effects stereo compressor / feedforward stereo compressor / 6 HP ⇣ STEREO COMPRESSOR is a classic analog feedforward compressor, which takes its sidechain split directly from the input signal. It is based on the THAT4305 Analog Engine® single-chip with integrated Blackmer® VCA. 1/3 key features Analog Compressor Stereo Signal Path THRESHOLD, RATIO and GAIN ON/OFF Switch for Signal Comparison Up to +20dB Make-Up Gain STEREO SUM Compatible Skiff friendly Wrong polarity protection specs & downloads width: 6 HP depth: 28 mm power: 35 mA @ +12V / 26 mA @ -12V documentation videos description / manual STEREO COMPRESSOR has two independent signal paths in order to process stereo signals. The left input is normalized to the right, if you want to compress mono signals instead. The module has three controls and a switch: THRESHOLD determins the level at which the compressor starts working. This can be set from -40dB to 20dB. RATIO sets how much the compressor turns down the volume when the threshold is reached (INF:1 to 1:1). GAIN regulates the amount of make-up gain (-20dB to +20dB) that is applied to the signal. Additionally there is an ON/OFF switch that makes it easy to compare the dry and compressed audio signal. Please note that if you turn THRESHOLD counter-clock wise to the left, you reduce the threshold from 20dB (fully cw) to -40dB (fully ccw). Hence the compressor starts working earlier. If you turn RATIO counter-clock wise to the left you increase the amount of compression from 1:1 (fully cw, no compression) to INF:1 (fully ccw, infinite compression). So turning the knobs down corresponds to compressing the signal. The pictures below show the knobs in a neutral position where no compression is applied. STEREO COMPRESSOR has a similar design as the STEREO SUM CHANNEL modules. If you want to add some compression to your mix STEREO COMPRESSOR is a perfect addition to your STEREO SUM Mixer. prev Up next

Additionally there is a MIX out, where both sides are available at a single output jack. Using the Pan knob or the CV IN you can pan between both sides. If there is only one audio source connected to IN L this signal is multiplied to the other channel in order to provide a crossfade functionality. prev Up next

Utilities & PSU cv expert / dual polarizer, offset & gain with LFO / 4 HP ⇣ CV EXPERT is a very compact yet powerful CV tool that is equipped with all the important functions you need to customise your control voltages. With its internal LFO, it is immediately ready for use without further patching. 1/3 key features 2x Polarizer 2x Offset 2x Gain Triangle or Square Wave LFO Internal normalizations Low HP format Skiff friendly Wrong polarity protection specs & downloads width: 4 HP depth: 30 mm power: 50 mA @ +12V / 32 mA @ -12V documentation videos description / manual CV Expert (Cve) is a versatile dual-channel tool for customizing control voltages. Its internal LFO is normalised to both inputs and allows you to choose between a triangle or square wave via a jumper on the back. The LFO connection is automatically interrupted when an external CV is inserted. Adjust the LFO rate with the LFO RATE potentiometer. The signal received at the DC-coupled inputs IN ① and IN ② passes through three CV tools: Polarizer The PLRZR potentiometer enables voltage attenuation and inversion. At the midpoint, the signal is eliminated. Turning to the right allows the original voltage to pass through (as with an attenuator). Turning to the left inverts the signal, e.g. positive signals are converted into negative signals. Offset Adds or subtracts voltage from/to the passing signal. OFFSET control determines the offset range. In the center position, there is no voltage offset. Turning the control to the right shifts the voltage to the positive range, while turning it to the left shifts it to the negative range. Gain Amplifies the signal with a maximum gain of 2 at the GAIN control's maximum position, effectively doubling the applied voltage (e.g., +1V becomes +2V, +3V becomes +6V, or +4V becomes +8V). The voltage is capped at a maximum of +/-10V. CV EXPERT QUICK START GUIDE: CVE_QUICK_START .pdf Download PDF • 422KB prev Up next
