ADDAC System - 203 CV Mapping

available

This is a new revision of one of our first modules, back from 2010. Now more compact in 6 HP and with an Offset CV input.The incoming signal amplitude is controlled by a [GAIN] attenuverter circuit allowing to attenuate the signal as well as invert its phase. A back jumper can set the maximum gain amount to either x1 (unity gain) or x10. DIY modifications can be made by changing its resistors. After the Gain an offset can be added to the signal, displacing the signal up or down (-5V to +5V) this can be adjusted using the [OFFSET] knob and CV input.When using no input using the [OFFSET] knob and CV input will generate an output between -5V and +5V.DIY-Kit-Type:SMD-Kit-1. This is a Do-It-Yourself kit, not an assembled module. The kit includes all parts to build the module. All SMD parts are pre-soldered, only trough-hole parts to solder.

ADDAC System - 309 CV To Expression

available

ADDAC309 CV to Expression allows a simple and straight forward connection between modular and effect pedals that features expression pedal TRS inputs.Instead of using an expression pedal into the effects pedal the user can use this module in between a CV source and the effects pedal to be controlled. This is a great way to control the available parameters on the effects pedals straight from a CV source.ADDAC309 features 2 channels each with a CV input with attenuator and a 1/4" jack output.This is a passive module, the power needed for operation is taken from the pedal power instead of the modular frame, this allows for perfect matching of the pedal’s operating voltage which can range from 3,3 V to 9 V.DIY-Kit-Type:THT-Kit-1.

Chair Audio - Ilse

available

Ilse is an elegantly minimal, yet fully functional synthesizer voice in a compact 10 HP Eurorack module. The only thing you need to let it meow is a CV source to trigger its 1V/Oct frequency input (or a MIDI to CV converter and a MIDI sequencer) . Because it has a low part count it is ideal for Eurorack beginners or entry-level DIY projects.Ilse is named after a cat, living in the legendary “Villa” in Weimar, Germany. The “Villa” was a place where a community lived and came together. Many underground concerts and parties took place here before the house got sold, renovated, and the mayor moved in. We created the graphics on the aluminum face-plate in her memory. Ilse (the synth) makes great acid sounds, so it was only logical to illustrate a cat tripping. Turn the knobs to make her look around or roll her eyes.Ilse is designed to be affordable, easy to build, yet flexible, and feature rich. It is a synthesizer voice for your Eurorack, but can even be driven without a rack using two 9V batteries (not included).Ilse is fully open source (KiCad schematic and layout is available in a git repository) and inspired by Syntherjack’s single-chip synthesizer Totoro. Check out his website with nice explanations, e.g. on the filter (we use the same filter on Ilse). We extended the design for external voltage control on filter, oscillators and LFO. Unlike Totoro, Ilse is designed around a unique oscillator design, which integrates the exponential conversion directly into the oscillator core. This results in an efficient circuitry saving you build time, parts and costs.PCB and face-plate are manufactured in the EU.Features:Functions• Two saw tooth oscillators• Bridged-T low pass filter with resonance control• Triangle LFO with speed control, and routing to filter and/or oscillators• Simple mixer and detune for oscillatorsControls• LFO Speed, Filter Modulation, Osc Modulation• Filter Cutoff, Filter Resonance• Tuning, Osc2 Detune• Osc1/Osc2 (Filter in)• Output volumeInput/Output• 1V/Oct CV for oscillators (0-5V)• Gate (0-5V)• Filter cutoff (0-5V)• External filter input• Volume controlled output• LFO Speed (linear, via solder pad on back, 0-8V)• Oscillator 2 detune (linear, via via solder pad on back, 0-8V)DIY-Kit-Type:THT-Kit-1.

Frequency Central - Akropoli

available

Akropoli is an extension and enhancement of our successful Little Melody and High Towers modules, offering the features of both of these modules as well as some of it’s own unique features such as mute buttons per channel, manual transpose knob and 1V/oct transpose CV input. Akropoli operates using our proprietary TOOL V2 code, and can count in integers as well as multiples for even more subtle and evolving variations:• top of the dial is /1• clockwise from the top are /2, /4, /8, /16, /32, /64, /128• anticlockwise from the top are /3, /5, /6, /7, /9, /10, /11Akropoli is a generative sequencer based around clock divisions and a chromatic quantiser, used to create in-the-moment licks and riffs. It is more that the sum of it’s parts.Akropoli’s internal operations can be considered as 4 clock dividers patched into a CV mixer via attenuators. The attenuators select notes over a 5 octave range, the clock dividers determine how often those notes are added to the mix. The final output of Akropoli is quantized chromatically for fast set up and continuously pleasing results. Akropoli has an onboard transposition knob, as well as a 1V/oct transposition CV input.The 4 clock dividers are labelled A, B, C, and D. They all receive clocks from the same source, the divisions may be selected using the presets and the individual division selectors. The clock dividers can be set to count up, down, or to one of a variety of modes that move between counting up and down. For further information on Presets and Modes see the Little Melody User Guide.Additionally, each clock divider has it’s own binary output (either high or low), these 4 outputs can be used to clock/gate/trigger other stuff on other modules to great effect.DIY-Kit-Type:THT-Kit-1.

Frequency Central - Berlin School

available

Berlin School is based around the classic CD4017 Johnson counter chip, under the control of a 16F1765 PIC which provides a few novel features.So what can Berlin School do? Well, it’s lots of fun, and far more fully featured than any old Baby 8, courtesy of being under PIC control. For example:you can externally control the length of each individual step via the DIV.CV input socket, by using another CV source, such as another Berlin School, an LFO, or evena sample and hold module – so any step can last for any clock length from 1 through to 8.You can externally control transposition of Berlin School via the TRANS.CV input socket, by using an external controller, such as another Berlin School (running at a slower speed), a 1V/oct keyboard (love this!), of any other CV source such as Little Melody for example.You can also do both of the above manually by using the DIV knob and the TRANSPOSE knob.Live tweaking of note information for each step in real time, secure in the knowledge that everything is accurately quantised.Berlin School has a 5 octave range (0V to 5V). A fun little feature is that if you’re running a sequence and then transpose it, any notes which end up beingtransposed above 5V are transposed down by one octave (rather than ‘clipping’ against the 5V ceiling), thus preserving the melody!All told, it’s hands on, tweakable, and lends itself perfectly to on-the-fly live use courtesy of the variations that are available from the use of the onboarddivider, transposition features and quantiser.Berlin School is perfectly partnered with Little Melody, and can be clocked and reset from an suitable external controller.Features:• 8 inputs (1 through to 8), each with micro-attenuators (which can be set with a small screwdriver)• 8 buffered inverted outputs (A through to H) which are 180o out of phase with the inputs• 8 buffered normal outputs (A through to H) which are in phase with the inputs• A switch matrix of 64 push on/push off switchesDIY-Kit-Type:THT-Kit-1.

Frequency Central - Polygraf

available

Polygraf is a step sequencer that features record/edit and playback functionality across 32 different patterns of up to 16 steps.Polygraf has four binary outputs (can be High or Low), labelled One, Two, Four, and Eight. During playback, Polygraf outputs a combination of High and Low for each of those outputs. The combinations can be edited by setting Polygraf to write mode and following the necessary procedure.Patterns: Polygraf has 30 Patterns (Patterns 1 to 30) that can be overwritten/edited, and 2 Patterns (Patterns 31and 32) that cannot be changed. Patterns are composed of up to 16 Steps (but can be recorded to be shorter).Steps: Polygraf has four binary outputs (can be High or Low), labelled One, Two, Four, and Eight. A Step outputsa specific combination of High/Low for each output. During playback, clocking advances Polygraf to the nextStep (or wraps around to Step 01 if there isn’t one). Individual output configuration can be uniquelyrepresented as a 0 to 15 number known as the State.State: A unique combination of On/Off for all of the outputs. There are 16 possible combinations thus 16possible States. We number these 00 to 15. A State’s identifying number can be determined by adding the valueof the outputs that are On. E.g. if outputs One and Four are On (and Two and Eight are Low) then the number is05 (because One + Four = 5).Pattern chaining: When in Play mode, Polygraf’s STATE potentiometer is used to determined the pattern chaining mode. Thepotentiometer acts as a four position switch. When changing between positions on the switch, Polygraf’s 7 segmentdisplays briefly indicate which position you are in, eg briefly showing ‘02’ to indicate the second position.DIY-Kit-Type:THT-Kit-1.
