ADDAC System - 605 Spectral Tilt

available

The TILT EQ concept was first introduced in the 1970's by Quad Ltd, featured on the company’s model 34 preamplifier. The tilt control tilts the frequency spectrum of the audio signal by simultaneously boosting the treble and cutting the bass frequencies, or vice versa, making it a simple to use but powerful EQ.As stated by Quad Ltd, it was designed to produce a very gradual change in balance across the musical spectrum without changing the overall subjective level. This gradual fall from Bass to Treble, or vice versa, means there’s no sudden change and hence no ‘coloration’ added to the sound, the sound will remain entirely natural but with a slight added bottom or high end. In practice, it rotates most of the audio-range frequency response around a 1kHz axis, so as to change the overall balance of the sound from warm to cool without affecting either the apparent volume or the "color" of the sound.Here we introduce this idea into the modular world in a stereo configuration. CV input with attenuverter was added for the Tilt control as well as a Spectral Motion switch that allows stereo spectral matching or inverted spectrum use of the Tilt control: Left = Right matches both channels direction, i.e. when left channel is tilted to the low end the right channel will also be tilted to the low end. Left ≠ Right inverts the Right channel spectrum, i.e. when left channel is tilted to the low end the right channel will be inversally tilted to the high end, or vice-versa. This possibility is extremely interesting when applied as a stereo effect, in other words, a spectral EQ panner.DIY-Kit-Type:SMD-Kit-1. This is a Do-It-Yourself kit, not an assembled module.

Befaco - Hexmix

only 2 left

Hexmix System is a six channel performance mixer specially designed for Eurorack.The system has two separate modules, the core of the mixer: Hexmix that has six channels with three band EQ, mute, pan and EQ section on the master, and Hexpander that add three auxiliar sends per channel, PFL, individual outs and balanced output.The mixer has a strong inspiration in classical DJ mixers, providing sharp EQ’s for enhanced performance, auxilliar send for effects and individual outputs to record your performance per channel.The system is designed to be placed in 6U, instead of the traditional 3U paradigm in Eurorack. So we will have every feature for each channel vertically as a conventional tabletop mixing deck.Six channel mixer with three band EQ, vactrol mutes, pan and volume control per channel.Inputs for every channel are located at left side of Hexmix. Each jack is normalized to a VCA Expander connection in the back, so if you have a Hexmix VCA , you will have the output of each VCA to every input. connecting a jack in any input will disconnect whatever is coming from VCA.Gain is set to unity, so it will act as an attenuator of the input signal. Mutes are clickless, as they are vactrol based. This circuit provide some decay on the mutes, rather than a sharp cut.Swithces have latch position and momentary ones to unmute the channel, providing some really nice performative capabilities.EQs are quite sharp (12dB) inspired in classic dj mixers to aggresively cut selected frequencies.Master section has it’s own EQ and volume control for the mix of all channels. Master EQ is softer than individual channel’s (6dB) and it’s meant to provide control over the final mix.It’s possible to change output level from line to synth with a switch located in the back.This will be pretty useful when used in combination with hexpander, that provides a balanced out at line level. Like this its possible to have a mix at synth level to re-route the master signal while having an output to PAFeatures:• Six Channel Performance Mixer• Three Band EQ per channel inspired in classical DJ mixers• Vactrol based mutes with momentary action.• Pan and Volume control• VCA Expander connection to plug every channel of an Hexmix VCA directly.• Selectable Line or Modular output level.DIY-Kit-Type:THT-Kit-1.

Befaco / Divkid - Stereo Strip

sold out at the moment

Stereo Strip takes the idea of a channel strip and makes it modular. We hope that by bringing this long-established component of the audio engineering world into the Eurorack environment and by adding CV control over its key parameters that you will find new, creative ways to use it in your patches!It features stereo inputs and outputs for audio or CV with EQ, voltage controlled panning, stereo VCA, performable mute and input/output level switching for Eurorack or line level uses. Abusing the input level switching allows for some musical, modulate-able and highly shapeable distortion sounds too.Stereo Strip was designed to be a creative part of a modular patch. Creating stereo images from mono sources, shaping and modulating existing stereo images, synthesising stereo pseudo ring modulation, sweetening FX with EQ or drastically wave shaping your oscillators, creating send FX routings with benefits or it can simply be used as a channel strip at the end of chain in a patch.The addition of line level gain boosting (for the input) or reduction (for the output) allow it to work as a stereo input or output interface for external gear with the advantage of the VCA, panning and the EQ to shape the sound. Experiment with bringing external gear into the Eurorack format and then shape and modulate those sounds them on the way in!Try patching Stereo Strip anywhere you would place a VCA in a system and/or explore its EQ and voltage controlled panning, which are rarer additions to the sound sculpting options for the Eurorack format.This module is designed in collaboration with Ben Wilson aka Divkid.Features:• 3 band EQ• Panning (manual and voltage controlled)• VCA level control (manual or voltage controlled)• 3 way performance muting (on-off-momentary)• Soft clipping limiter (distortion!)• Line level input and/or output adjustmentDIY-Kit-Type:SMD-Kit-1.

Zlob Modular - VC F3DB

sold out at the moment

VC F3DB stands for Voltage Controlled Fixed Filter Feedback Distortion Bank. The simplest description is it’s an analog 16hp six band voltage controlled fixed filter bank. But with the additions of so much gain, clipping, feedback, and self-oscillation it becomes a very flexible and unique gestural sound sculpting tool capable of; graphic equalization over 6 octaves, multi-band distortion, spectral processing, crude vocoding, multi-frequency envelope following, self-modulation, and even as an instrument on its own. With no input it can be used as a pseudo chaotic “harmonic” feedback oscillator.The filter frequencies were specifically chosen to emphasize more ambiguous and dissonant intervals. Although the frequency bands are spread out over many octaves I purposely tried to leave out “3rds” besides a major 10th at the top frequencies to even out all the dissonance below. But the frequencies aren’t exactly equal tempered, so it’s relative. The bands roughly equate to F2, B3, F#5, C6, F7, A8.The design is based on the Moog 914 filterbank, which it borrows the frequency bands from. But this circuit uses active filters with opamps inspired by YU Synth opposed to passive cells using inductors on the original. The 88hz is a low pass -24db/oct and 7k is a high pass -24db/oct, the rest are -12db/oct band pass filters all with a Q around 4.The hard and soft clipping circuit on the input is fairly standard which appears in many different iterations of classic guitar pedals. But it has a lot of gain and can even boost line level signals. What makes it a bit unique is the feedback on the clipping circuit which needs to be turned on by the GFB(gain feedback) switch and the amount can be controlled by the Gain FB pot which can add some fuzz/bite to the signal depending on which clipping switch is engaged or at the extremes it will self oscillate from audio rate to LFO sort of clicking range. All the clipping stages in the module are using silicon diodes.Consult the Signal Flow Chart to the left for a rough visual breakdown of the controls,in/outs,normalizations, and optional settings for the module.Each band can also be muted by the top toggle switches or clipped(at the VCA) by the top slide switch which makes this design a bit different than other filter banks. As well as the overall feedback section(bottom middle) takes the sum/all bands out through a VCA(controlled by the feedback pot and FB CV) back to the input gain/clip circuit. and you can also tap into this using different sends/bands to the FB In jack to break the normalization. With this extra feedback “resonance” you can get more whistley and howly filter sounds kinda like the Serge res eq, which can also go into self oscillation.All CV ins are expecting +5v to open the VCAs (they wont respond to negative voltage), once you get closer to +8v or so it can clip the VCA regardless of the gain settings or clip switches. Output amplitude in high gain settings will exceed 10vpp and can get up to 20vpp. The envelope followers tend to stay around 0-5v out, but with clip switch active they can go up to 10v.Since this is a high gain module there can be bleed between the bands in certain configurations and situations. Also in high gain modes with higher frequencies the 2.8k and 7k bands can bleed a little with the VCAs closed.This is a highly involved DIY all through hole project.
