Modulation & Random envoltura / dual analog envelope / 14 HP ⇣ Experience the classic charm of analog envelopes based on the Roland System 100M 140 Dual ADSR module, made snappier with intuitive visual controls. Furthermore, thanks to its built-in VCA, manual level controls, potent cyclical gate generator, and user-friendly trigger buttons, ENVOLTURA elevates your sound-sculpting prowess to new heights. And when you double it up, prepare for twice the thrill! 1/3 key features Based on System 100M 140 Module Dual ADSR CV Level Control Inverted Output Retrigger Input Push Inputs Short and Fast Switch Manual Trigger Buttons Cycle Functionality Skiff friendly Wrong polarity protection specs & downloads width: 14 HP depth: 30 mm power: 89 mA @ +12V / 56 mA @ -12V documentation videos description / manual ENVOLTURA boasts a highly responsive analog envelope with controls for ATTACK, DECAY, SUSTAIN, and RELEASE. When a gate signal is applied to the GATE input, the envelope is triggered, and a corresponding CV signal is produced at the OUT, with an inverted version available at the INV output. Furthermore, an end-of-cycle GATE signal can be accessed from the EOC socket, which outputs a gate signal when the sustain phase of the envelope ends. The signal remains high until the start of the next attack phase. The gate is indicated by an LED. You have also the flexibility to retrigger the DECAY phase of the envelope by applying a trigger signal to the RTRG input. IN addition to manual level adjustment via the slider level potentiometer, you can modulate the envelope's level using an internal VCA by patching a CV signal to the VEL input socket. An exclusive attenuator enables precise control over the level modulation. For dynamic modulation, simply patch any CV source to the PUSH inputs and manipulate both the envelope's length and level. Fine-tune the overall length range with the SLOW/FAST switches, and if desired, activate the CYC switch to let the envelopes cycle within specific ranges. Please note that cycling may stop for very fast cycles and that the envelope doesn´t restart from 0 volts. Finally, you can also trigger each envelope manually. Please note that both ADSRs are normalised to each other, so that pressing a button always triggers both envelopes, unless a patch cable is connected to the gate input of the other.

It can be used as a control voltage, clock source or patched into the audio path for drum synthesis. The frequency and the frequency range can be controlled by turning the frequency knob and rate switch. Additionally the width of the pulse wave may be manually adjusted. An LED indicates the current speed of the LFO. On the bottom of the panel you will find two touch plates. Using these you can “play” the LFO and become a part of the circuit. By pressing your finger onto the HOLD plate you will be able to stop and reset the LFO cycle. It will start over again when the finger is released. The second touch plate PUSH is altering the frequency of the oscillator. Roll your finger from the top side of the plate to the bottom and the rate will be increasingly speeded up. Or directly press you finger an all plate parts and go crazy! After releasing your finger from the PUSH plate the frequency will smoothly recover to its original speed set by the frequency knob. prev Up next

Oscillator klangmaschine / dual digital fm synthesizer / 16 HP ⇣ KLANGMASCHINE is a powerful tool for creating a wide range of sounds, from simple sine waves to complex and evolving textures. It combines two simple frequency modulated synthesizers to create a very powerful and versatile digital sound source. 1/3 key features 2 Voice FM Synthesizer plus Noise Generator CV over all FM Parameters Tone Control Internal VCA Internal Mixer Individual Outputs Wrong Polarity Protection specs & downloads width: 16 HP depth: 28 mm power: 98 mA @ +12V / 56 mA @ -12V documentation videos description / manual FREQUENCY MODULATION (FM) SYNTHESIS is a method of sound synthesis that uses the modulation of the frequency of one waveform by another waveform to create complex and evolving timbres. FM synthesis uses a modulator waveform to modulate the frequency of a carrier waveform. The frequency of the modulator is usually in the audio range, while the frequency of the carrier determines the pitch of the resulting sound. On both sides of the module are the parameter controls for the FM voices. The sliding potentiometers control FM AMT, FM FREQUENCY and PITCH. Each parameter can be voltage controlled. Attenuators control the amount of incoming CV. If nothing is connected to the CV inputs, the above CV attenuators change the response curve of the parameter sliders. Above the sliders is a TONE control, which lets you emphasize either low or high harmonics, and a VOLUME control, which affects only the MIX OUT. Connect your pitch CV to the V/OCT to play notes. The left V/OCT input is normalized to the right. In addition to the two synthesizer voices, there is a volume control to add white noise to the MIX OUT. You can either listen to the oscillators individually at the OUT jacks, or tap a mix of all three sound sources at the MIX OUT. If you connect an envelope CV to the VCA CV input, you can control an internal VCA. If no envelope CV is connected to the VCA CV input, the LED lights dimly to indicate that all three voices are being output at the MIX OUT. As the level rises, the LED indicates the volume level. If a patch cord is connected to VCA CV without CV, the LED is off to indicate that no signal is being output. If the VCA is opened via CV, the LED again shows the volume level. In the "Just a Minute - Live Techno" videos shown above I use KLANGMASCHINE for the lead sound. Have a listen!

Oscillator pyxis / adaption of mutable instruments "plaits" / 8 HP ⇣ PYXIS condenses all of Plaits' functionalities into a more compact hp footprint, while further pushing the principle of "simplicity first" to unparalleled heights. 1/3 key features Please check out the original module by Émilie Gillet which is an all time Eurorack classic already Illuminated Pyxis Logo Wrong Polarity Protection specs & downloads width: 8 HP depth: 28 mm power: 50 mA @ +12V / 5 mA @ -12V documentation videos description / manual In order to easily tweak and change the sounds there are four main potentiometers that will change Timbre, Harmonics, Morph and Variant, which is any possible mixture of OUT and AUX. Freq has been put onto a small trimmer potentiometer to avoid any accidental change in pitch. On the bottom of the panel you will find all necessary jacks to control Pyxis via CV. Timbre, Morph and Freq have dedicated attenuverters to adjust the incoming CV signals. Yeah…but…where are the LEDs? Instead of always directly jumping to chord mode and watching the LEDs change, isn‘t it much better to listen and trust your ears to choose the right sound? Tweak the four potentiometers, change the program with the two buttons (Sound and Percussion Mode) and listen to the wide range of sounds Pyxis is able to generate. Let yourself be surprised what is hidden behind the programs you would usually not choose following the LED indicators.

Filter & EQ natural state / dual envelope ducking filter / 16 HP ⇣ Natural State consists of two 24db filters with a CV decay envelope and an internal LFO. It is designed to filter two waveforms in the most ear-friendly way possible to create natural and organic sounding grooves and soundscapes. 1/3 key features Dual Filter Dual Envelope Decay CV Filter CV Filter Ducking Internal LFO normalized to Filter CV Envelope Output Slider Pots Wrong Polarity Protection specs & downloads width: 16 HP depth: 28 mm power: 81 mA @ +12V / 55 mA @ -12 documentation videos description / manual Each of the two channels has a DECAY slider that adjusts the decay length, an OPEN slider that adjusts the filter cutoff, and a FORCE slider that adjusts the amount of decay CV that affects the filter. The STRIKE input takes any CV from +1 volt and triggers the decay envelope. Both the decay and the filter cutoff can be controlled via the CV inputs DECAY and CTRL. Attenuators can be used to change the strength of the applied CV. The decay attenuator also acts as a DECAY CV offset. A subtle internal LFO can be routed to the filter cutoff, which is attenuated with the CTRL controls. The LFO range is rather slow to create smooth filter sweeps. The resonance of the individual filters can be changed with the PEAK potentiometers. When the DUCK control is turned to the right, the decay of the left channel increasingly suppresses the signal of the right channel, creating a ducking effect. Both decay envelopes are also routed to the ENV sockets for further external processing. NATURAL STATE QUICK START GUIDE: NATURAL_STATE_QUICK_START .pdf Download PDF • 764KB prev Up next

Utilities & PSU stereo total / mono to stereo converter, stereo width controller and imager / 4 HP ⇣ Mono: the original black and white movie. Stereo: the epic 3D blockbuster. Let's face it, mono might be the classic, but stereo is where the party's at! STOTAL_BACK.jpg 1/3 key features Mono to Stereo Converter Stereo Width Controller Stereo Imager Buffered Input Multiple Two Separate Stereo Processing Blocks Wrong polarity protection specs & downloads width: 4 HP depth: 25 mm power: 15 mA @ +12V / 10 mA @ -12V documentation videos description / manual STEREO TOTAL is a Mono to Stereo Converter, Stereo Width Controller and Imager. It consists of two building blocks. The first block A is a Stereo Simulator that creates a stereo signal from an incoming mono signal. This is done by splitting the mono signal in two separate signals, passing the left through an R-C network to reduce mid range frequencies and the right through an operational amplifier in differential mode to obtain an output as a difference to L. Knob A STEREO DEPTH controls the depth of stereo, but also places the signal within the stereo field. Because the signal is filtered, mid range frequencies will be changed as you turn the knob. Additionally the incoming mono signal is multiplied (buffered) and a lossless copy is available at the MONO OUTPUT jack in order to allow further mono signal processing. The second building block B is a Stereo Width Control that allows you to change a stereo signal from mono to wide stereo. This is achieved by summing both signals L and R to create a mono signal when knob B STEREO WIDTH is turned fully counter-clockwise and by splitting them via complete negative crosstalk, when the knob is turned fully clockwise. Fully clockwise the stereo signal contains no centre image at all. Initially the module was designed to be used with mono signals only, but you may also use both building blocks separately. You can convert a mono signal to stereo with block A while you can also change the stereo width of another stereo signal with block B. You can also independently convert two mono signals to stereo using both blocks at the same time (you need to patch a dummy cable to the right channel of stereo input B to disconnect both blocks). A mono signal to block A will run through both blocks when nothing is patched into the block B stereo input jacks. prev Up next

Sequencer isi wren / repeatable random gate and cv generator / 4 HP ⇣ ISI WREN is a great sequencer to quickly generate random sequences and lock them on repeat to create catchy and pounding techno synth lines. 1/3 key features Random CV and Gate Looped Sequences Change Sequence Length Adjust Sequence Range Repeat Different Sequences CV Loop ON/OFF CV Length, Range and Repeat Sync to external Clock Skiff friendly Wrong polarity protection specs & downloads width: 4 HP depth: 30 mm power: 35 mA @ +12V / 12 mA @ -12V documentation videos description / manual ISI WREN is a digital sequencer that generates random gate and CV signals synchronized to a clock connected to the CLK input. Depending on the CHANCE slider potentiometer, it either generates random gate and CV signals in the center position or locks the sequence in the upper or lower position. The closer the knob is to the center position, the more frequently the signals change. When a gate signal is patched to the RPT input, the sequence is repeated regardless of the slider position. If you repeat a sequence in the upper position of the slider, two different sequences are repeated alternately. In the lower position, only one sequence is repeated. With the MODE potentiometer you can set the length of the repeated sequence, the CV range and the repetition of the sequences. Set the mode toggle switch to STP and adjust the sequence length from 4 to 16 steps. Switch to RNG and adjust the CV range (octave range). In RPT mode, you can adjust how many times an alternating sequence repeats when the CHANCE slider is in the up position. Mode settings can also be voltage controlled. Patch a CV signal to MODE and adjust its level with the attenuator in order to change the length of a sequence, its range and the repeat mode externally. If no cable is patched to MODE the attenuator acts as a response adjustment of the MODE knob (e.g. smaller range of steps with one turn of the MODE knob if the attenuator is turned to the left). Use the GATE output to control an external envelope generator and connect the CV output to the 1V/OCT input of any oscillator. prev Up next

Utilities & PSU once in a while / 3-channel mono, 1-channel stereo CV click-less mute / 6 HP ⇣ Tired of muting with all the drama of a Shakespearean tragedy? Say goodbye to the click drama with our click-less mute module. It's like giving your modules a chill pill – no more dramatic exits, just smooth audio bliss. 1/4 key features 3-Channel Mono Mute 1-Channel Stereo Mute Click-Less Muting based on Vactrols STRIKE Buttons for Performance Mutes LED Indication MUTE or GATE Mode for Channels 1-3 Wrong polarity protection specs & downloads width: 6 HP depth: 35 mm power: 25 mA @ +12V / 14 mA @ -12V documentation videos description / manual ONCE IN A WHILE is a 3-channel mono and 1-channel stereo mute switch with CV control. Any audio or CV signal fed into the IN jacks and taken from the OUT jacks can be muted and unmuted with a latching MUTE button per channel. If a channel is not muted, you can also mute it momentarily with the dedicated STRIKE button. Conversely, you can unmute a mono channel with the same STRIKE button if it is muted (this is not possible with the stereo channel). LEDs indicate whether a signal is being passed. You can also use CV signals to mute channels. Just connect a gate, LFO or envelope to the CV inputs and the channel will be muted from a voltage of about 2 volts. Even if you apply a control voltage to the CV inputs, you can mute the signal with the MUTE (latching) or STRIKE (momentary) buttons. Before soldering the module, you can decide if you want to use one of the mono channels alternatively as a low-pass gate. It's a single resistor you need to change and a mono channel becomes an LPG when a CV signal is patched into its CV input. So if the channel is muted, it will be unmuted again when the CV input is high. Mute mode = CV mutes the signal when it is not muted. LPG mode = CV unmutes the signal when it is muted. The first input is normalized to the other inputs. Therefore, you can also use ONCE IN A WHILE as a 1 to 4 buffered multiple with individual mute switches. ONCE IN A WHILE was designed to provide click-free muting for audio signals, but has become much more performance-oriented with the addition of momentary STRIKE buttons and CV inputs. It was optimized to be used with the VTL5C9 Vactrol. You can also use other vactrols, but then you may get clicks when muting audio. prev Up next

Oscillator yaksha´s fate / mutable instruments "rings" adaption / 8 HP ⇣ In this rendition, the emphasis was placed on showcasing all the adjustable parameters prominently while concealing those that could impact tuning and harmonics. This design approach allows you to immerse yourself in uninhibited live performance, without the concern of inadvertently altering frequency or structure, ensuring a seamless experience for both you and your audience. 1/3 key features Please check out the original module by Émilie Gillet which is an all time Eurorack classic already Illuminated Yaksha´s Fate Logo Wrong Polarity Protection specs & downloads width: 8 HP depth: 38 mm power: 125 mA @ +12V / 12 mA @ -12V documentation videos description / manual It has all the functionality of the original module except for the two Outputs Odd/Even, Frequency CV (also Fine Tune) and Structure CV (Harmony). You may switch Filter CV or Decay CV to control Harmony via jumper though. The two outputs Odd and Even are mixed together on the OUT jack, but you can fade from one to the other using the Partial Knob. This way you get an additional sound shaping option and some kind of trigger control when two or four notes polyphony is selected. In contrast to the original Yaksha´s Fate will rather act as a VCO producing a constant tone (through very fast trigs) if you plug a CV source into 1V/OCT without a trigger at the TRIG input.

Meet the Swiss Army knife's ambitious cousin – the multitasking marvel that sits in front of your Eurorack, ready to unscrew musical conundrums, slice through soundscapes, and twea-zor its way into your sonic heart. workbench / usb powered multi utility tool / 0 HP ⇣ Meet the Swiss Army knife's ambitious cousin – the multitasking marvel that sits in front of your Eurorack, ready to unscrew musical conundrums, slice through soundscapes, and twea-zor its way into your sonic heart. key features Multiple LFO Attenuator documents Fader Swap USB-Power description / manual Multiple 1 to 3 multiple with one inverted output. The multiple is normalised to the swap unit of the module. LFO The LFO provides a triangle and square wave and can be reset by an external gate or clock signal. The LFO signal can be attenuated with the slider pot and its rate may be varied with the RATE potentiometer. An inverted copy of the triangle wave is normalised to channel A1. An inverted copy of the square wave is normalised to channel B1. These connections are independent from the LFO attenuator and may be interrupted by patching a cable into the channel A1 or B1 input or by the normalisation selection switches. You can choose to normalise the LFO or a fixed voltage of 0V to +5V adjustable with the VOLTAGE knob for all channels at once. Attenuator/Mixer WORKBENCH has four channels A1, A2 and B1 and B2. Any signal (audio or CV) patched into the inputs are attenuated by the slider pots. The channels of each section are daisy-chained, thus they can be mixed or the second channel can act as an offset (CV). The normalisation switch selects which voltage will be fed into the input if no cable is being patched (LFO or fixed voltage 0V to +5V). Fader The Fader mixes between two sources with a single slider. Both channel sections A and B are mixed into a fader circuit, if no cable is inserted into their outputs and the fader inputs. The fader output can be attenuated with the LVL knob. Swap The Swap unit exchanges the destination of one or two sources with the push of a button. This way you can route two signals to the corresponding destination of the other input. Anything patched into the Mult will also be multiplied to the Swap inputs of nothing is patched here. USB Power WORKBENCH is powered by standard USB power (+5V) and is fully compatible with your Eurorack system. You can choose to power it with a Mini B, Micro B or Type C USB cable. You can solder all USB connect or just one of them, if you have a favourite USB cable you want to use. Up
