ADDAC System - 104 VC T-Networks

available

Following our ADDAC103 T-Networks this new module is also inspired by Twin T-Networks circuits used in many legendary drum machines. A simple 4 voice module with frequency controls for each of the voices. This new module also features CV inputs with attenuverters for each voice Frequency. Due to the specificities of the circuit and to keep the module at a low price these inputs are not calibrated to 1v/octave.At each voice input there’s a gate to trigger converter so any input source is possible.Audio inputs can also be used as an input, in this case and due to the nature of the gate to trigger converter, each voice can be used as very destructive filters.The top 2 channels feature a higher frequency range, the bottom 2 channels feature a lower frequency range.Features:4 voices each with:• Frequency control with CV input and attenuverter Frequency Range Switch, Low/Mod/High• Trigger Input• Audio Output• Summing Mix output with Volume controlDIY-Kit-Type:SMD-Kit-2.

ADDAC System - 105 4 Voice Cluster

only 2 left

Following our ADDAC103 T-Networks this new module is inspired by its simplicity. This is a 4 voice Square Oscillator with VCA, FM switch and a slew decay for the incoming Trigger IN. All voices are then sent through a Multimode Filter.Each voice has its own VCA input where any input is accepted (Trigger, Gate, CV). The [DECAY] controls the slew decay applied to the incoming signal, if [DECAY] is fully anti-clockwise then it works as a Mute. The [FM ON] switches activate/deactivate the FM input coming from the previous voice: Voice 1 FM comes from voice 4, voice 2 FM comes from voice 1, and so on, so you can FM all of them in a FM loop.All 4 voices are summed and sent through a filter with controls over [CUTOFF] with an Attenuverter for the CV input and [RESONANCE]. Three filter outputs are provided [LOWPASS], [BANDPASS] and [HIGHPASS]The [EXTERNAL IN] input can be routed through a jumper on the back of the module allowing the incoming signal to go to:1. the filter input for processing an external audio source;2. all of the 4 voices Frequency control allowing for some experimental CV control over pitch of all 4 voices at the same time (due to the specificities of the circuit and to keep the module at a low price these inputs are not calibrated to 1v/octave).DIY-Kit-Type:SMD-Kit-2.

ADDAC System - 106 T-Noiseworks

available

This is the last module in our T-Networks series, a straightforward 4 voice module with frequency and decay controls for each of the voices. As the name already unveils we added a noise source and created 2 different circuits that explore the timbre of a t-network when used to filter noise.There are 2 different circuits in this module: voices 1 to 3 have a pre-vca t-network filter while in voice 4 the t-networks filter applied post-vca.At each voice input there’s a switch that sets which type of input to use; this signal will be used to control an internal VCA hence why the type of setting defined here is important:1. Trigger - Any incoming CV will be converted into a 1ms trigger as soon as it crosses its fixed threshold.2. Mute - This disconnects then incoming signal effectivelly muting the voice.3. Envelopes - This can be used with CV sources as well as Gate sources and simply follows the input signal.This incoming signal will then be processed by a slew circuit which adds a decay factor allowing the user to set the “Tail” of each voice.Trigger mode is mostly dedicated for percussive sounds while the Envelope mode is open to any external envelope control and able to control noise swooshes, swirls, crackles and pops simply out of t-networks filtered noise.Audio inputs also welcome use as a Trigger/Envelope input, in fact the results of using this method had us all extremely surprised, so please do try it out!Diferences between voices:The first 3 voices also feature a Timbre selector switch: Hat/SnareIn Snare mode all frequencies coming from the t-networks filter pass through to the output .In Hat mode it adds a High Pass circuit which removes the mid/bottom frequencies (characteristic of the snare strike) creating a higher spectrum output which is closer to a Hat timbre.All of these 3 voices are also differently tuned from each other to offer more timbrical options.Voice 4 is closer to a typical t-networks circuit but this time a peculiar one where the noise is gated by the vca and then sent through the t-networks filter.Hat and Snare are terms used very loosely here; they are timbrical references and do not in any shape or form try to effectively replicate the complex timbres of a real world Hat or Snare.Features:4 Voices each with:• Frequency control• Decay control• Timbre type, Hat/Snare (Voice 1 to 3)• Frequency Range Switch, Low/Mod/High (Voice 4) Input• Audio Output• Also and overall Summing Mix output with Volume control and 2 diferent output types (Normal/Dirt)DIY-Kit-Type:SMD-Kit-2.

Befaco - Kickall

only 2 left

Kickall is a 6HP compact synth voice that features everything needed to make a big fat Kick sound. A stable VCO that tracks V/Oct, a couple of VCAs, envelopes for volume and pitch and an aggressive waveshaper.The module has been designed with a kick synthesis patch in mind.The audio path consists of a sinewave oscillator that passes across a Square Waveshaper and two VCA’s. The first VCA is for the Volume envelope. The second VCA is dedicated to general volume. Thanks to his CV input, it is possible o apply accents or affects the dynamics of notes. Feeding this input with audio generates a basic AM operation expanding the sonic range of the module.In the control path, KickAll has two envelope circuits to modulate the first VCA oscillator’s pitch. Both envelopes are fired at the same time manually or via dedicated trigger input.Through its Tune input, KickAll tracks eight octaves with high accuracy. Plug your favourite sequencer or CV source to create patterns out of the kick range, or feed it with an audio signal, for frequency modulation Fx.Features:• Accurate V/oct tracking.• CV controllable Sine to Square waveshaper.• CV controlled envelope decay for main VCA.• CV control over General volume (after VCA).• Wide range pitch envelope control.DIY-Kit-Type:THT-Kit-1.

MRG Synthesizer - KICK

sold out at the moment

The MRG KICK is a clone of the TR-808 Bass Drum. The major difference with the original circuit, apart from some adjustementfor working at Eurorack levels and voltage, is on the trigger and envelope trigger mechanism.The MRG KICK has two trigger inputs (TRIGGER1 and TRIGGER2). Each of them has a different accent level, and can be usedindependently to generate kicks at different accents that can be changed dynamically. This trigger works eiter with gate signals(e.g. square LFOs) or proper trigger (impulses) signals.As the original, MRG KICK has control for TONE and DECAY. The DECAY in particular can be stretched to a longer decay than the original.Technically, this is not a simple module. Based on a four layers PCB, it uses a rail-to-rail opamp, capable of full 24VPP output signal.This makes the MRG KICK a loud, powerful 808-like BD, perfect for saturation and distortion.DIY-Kit-Type:SMD-Kit-1.

Music Thing Modular - Chord Organ

sold out at the moment

Chord Organ is the easiest way to get chords from a modular synth!• It's perfectly possible to create chords on a modular synth, but its a pain - lots of tuning and messing about. I wanted to create something as simple as a home organ with chord buttons. Chord Organ is exactly that; the top knob chooses a chord shape, the bottom a root note.• The full story of Chord Organ, including how it was inspired by a Bontempi Organ found in the street, is in this article over on Medium.• Chord Organ and Radio Music are identical modules; you can convert one to the other by installing new firmware over USB - details on how to install the firmware - and go back just as easily.• This video shows what you can do with a Chord Organ in a simple little case. Here the chord shape and root note are sequenced by an expanded Turing Machine and filtered through a God's Box Humpback Filter.• The top knob chooses the chord shape (Major, Minor, Drop 3 9th). The bottom knob chooses the root note. Both can be CV controlled.• The latest firmware now includes:• A choice of 12 waveforms (the original just had four) Program chords by uploading MIDI files Easy to use configuration page. Alternative tuning support by dropping standard Scala files onto the SD card (installation details).• There’s a long history of press-button-to-get-chord instruments; accordions, the Suzuki Omnichord, the Autoharp, or all those auto-accompaniment electronic keyboards that you used to see.Basically Chord Organ is a new firmware for the Music Thing Modular Radio Music module. It gives the module a completely different function. Instead of playing samples from the SD card, it synthesises chords. This is the full Chord Organ kit with dedicated Chord Organ silver Alu panel and button.Note: you need to purchase a MicroSD card and a Micro-B USB Cable elsewhere to set up this module. The Micro-B cables are the smallest type shipped with Kindles and many Android phones. You also need a card reader to write files to the SD card, many laptops and desktops already have them built in now. The very cheap $2 MicroSD cards are not worth the trouble they will cause you, buy genuine SanDisk or Kingston branded MicroSD cards from Amazon or elsewhere. 32Gb maximum… that’s 108 hours of lossless audio in 16bit 44.1khz. Total file limit per card is 1200 files.Features:For the build guide the process is identical to Radio Music, you just program with a different hex file – http://github.com/TomWhitwell/RadioMusicChord organ now tracks 1v/Oct if you use the latest software downloaded here! – http://polyfather.com/chord_organ/Details on how to load firmware onto the module can be found under the Software header here – https://github.com/TomWhitwell/RadioMusic/wiki/Preparing-the-TeensyDIY-Kit-Type:THT-Kit-1.

Nyström - Crum Drum

available

Crum Drum is a 4-voice drum machine with built in randomization and probability based sequencing designed by NYSTRÖMRhythms can be created and manipulated using the internal random sequencer or externally via MIDI USB. Press the beat button to generate new rhythms, adjust the probability to create continuous variations, and increase the randomness to modulate the sound of your beats! Generated sequences can also be sent out via MIDI USB and Crum Drum can also sync via analog clock in and out.The four voices of Crum Drum are Kick, Snare, HiHat and Bass (FM). There are 8 parameters knobs to sculpt the character of each voice allowing for wide variety of tones. It’s easy to create varied and organic sequences by adding modulation via the Probability and Randomness controls. Probability sets the chance that the selected voice will play per step of the sequence, while randomness increases the parameter modulation for each voice. The higher the randomness, the more each instrument parameter is modulated per step. Some of the instrument parameter controls have different behaviours depending on which voice is selected, so make sure to check the user manual for full details.Crum Drum features four global effects which are: Overdrive, Reverb, Delay and Swing. The delay-time is tempo synced and the subdivided differently dependent on the BPM.Power is provided via micro usb cable (not included)Features:• 4 instruments: Kick, Snare, HiHat, Bass• 8 sound parameters per instrument• Overdrive, Reverb, Delay & Swing• Send & Recieve Analog & Midi USB clock• Send & Receive Midi USB sequencing• Randomised and probability based sequencingDIY-Kit-Type:THT-Kit-1.
