Mailbag 10 - Feedback Modules VCZIII Oscillator

video upload by ranzee

"We are checking out the Feedback Modules VCZIII VCO Oscillator - both type A and B. The VCZIIIA and VCZIIIB are modelled after the EMS VCS3 synthesizer and have similar design and functionality as the original.

The mailbag series are videos where I receive parcels and open them for the first time. Plug the item in and test it out, showing you my first impressions of the items. These generally aren't reviews, nor are they a polished product demonstration. I'm more after the raw end user approach here."

Feedback Modules LFO100 - VCF2600 modulations

video upload by Feedback Modules

"VCF2600 is set in resonance mode and modulated by the LFO100.
All the waveforms and functions are tested one by one."

LFO 100

Complex analogue LFO from a vintage Japanese modular system!

We injected some steroids in this LFO and the results are lot of features.
Not only you can use individually the 8 waveform outputs, but you can use the
alternative two linked outputs for which you can select any of the waveforms.

This alternative output has a VCA so you can fade in the LFO signal in a

defined duration with a potentiometer.

The stairs like waveforms can be changed from 16steps, 8steps, 4steps or mangled.
All of these are seasoned with cv control and waveform reset.

2600 VCF

This filter is based on the classic 2600 from the seventies and uses the LM3900 Norton opamp chip.

It has an audio inputs, two CV ins and an audio out.

You can control audio input level, CV levels, frequency cutoff and resonance.

It has a beautiful sound and it can go from relatively clean to dirty and screamy depending on audio signal level and resonance.

Feedback Modules VCZIII EMS SYNTHI Based Voltage Controlled Oscillator Modules

VCZIII - Bass Sequence video upload by Feedback Modules

"VCZIIIA SAW is mixed with VCZIIIB SQUARE and with SUB modules.
All three are mixed to the VCF2600. The end of the patch is VCA2600 controlled by the ENV100.
You can hear the bubbly sound of the VCOs, these VCOs made with transistors are not so linear as other VCOs."

VCZIII - FM Modulation

video upload by Feedback Modules

"VCZIII VCOs modulating each other. The shape of the waveform is changed by the 4 slow sine LFOs combos of CMS SLOSINES. You can hear how the FM timbre is affected by the waveform nature."

via https://feedback-modules.myshopify.com

"The VCZIII voltage controlled oscillator modules are our latest creation and are based on the VCOs of one of the most revered analog instruments, the famous British pin matrix synth released in 1969. The VCZIII series VCO is a result of the collaboration of Feedback modules and CMS-LAB and is a modern re-creation of those temperamental, organic and beautiful sounding VCOs from 1969 but with enhancements and adaptations to the Eurorack needs of 21st century.

There are two type of VCOs, VCZIII A based on VCO1 with variable shape SINE & SAW waveforms, VCZIII B based on VCO2 & VCO3 with variable TRIANGLE & PULSE waveforms. Also, each VCO comes in two versions, one with normal fine tune potentiometers and one with precision multiturn potentiometer."

ALM Introduces BXx2 - ALM043 & STEREO SUM - ALM038

video upload by ALM TV

"The BXx2 is a dual channel preamp, EQ and mixer based on the classic Boss BX series mixers. Well loved for their unique character and musicality, the sound of the BX is found throughout countless techno records from the 80s & 90s.

With the inclusion of both input gain and level controls, each channel can be overdriven, producing the signature saturated and lively sound the BX mixers are known for. The EQ controls provide the channels with simple but great sounding high and low shelf EQs for emphasising and shaping sounds as well as the tonality of the drive. An additional Aux input allows another mixer or extra sound source to be chained in.

The BXx2 is a simple but powerful sound shaping tool, adding colour and warmth to anything patched through it.

It was designed in collaboration with Feedback Modules – based on their single channel PRE BX module and has a limited release of only 300 units. Visit Feedback Modules here: https://feedback-modules.myshopify.com/"

Introducing STEREO SUM - ALM038

video upload by

"The ‘STEREO SUM’ is a unity gain summing mixer that features four stereo input pairs summed as pairs to two independent mix outs or all as a single combined mix. It is a useful utility for efficiently combining outputs of multiple stereo sources, such as the MEGA-TANG and Jumble Henge mixers or multiple MFX returns.

The inputs accept stereo or mono signals (via normalisation) which can be audio or CV (module is DC coupled) and the top mixer’s outputs are normalised to the bottom mixer section meaning if the upper output is left unpatched the two upper inputs will be added to the lower output."

Feedback Modules MIX BX / MIX CR / MIX KM / eurorack mixer sound comparison

video upload by BRiES

"In this video I run different patches and sounds through these three mixers by Feedback Modules in an attempt to highlight the sound differences between them.

MIX BX, MIX CR and MIX KM have gain to spare and excel at saturating sounds, but they can do clean sounding mixes as well. The channel strips host an equaliser, a gain knob, two auxiliary mono sends (with stereo returns), a panning knob, clickless mutes and a volume control.

For a detailed overview of the features of the MIX BX (which has the same features as the other two mixers) you can take a look at this extensive playthrough video:"

Feedback modules MIX BX / eurorack mixer / extensive playthrough


"In this video I do a complete rundown of all the features this 6 channel eurorack mixer by Feedback Modules (a eurorack maker based in Romania) has to offer.

The MIX BX is perfect for making submixes for your drums or mix (and glue) together synths that benefit from some nice sounding saturation.

I demonstrate how to chain 2 channels to make hardstyle(?) kickdrums and how you can make use of the 2 aux sends to create a bus for parallel saturation.

At the end of the video there's a long 'no talking' segment where I systematically run through different sounds while tweaking the parameters... this might feel like an unnecessary boring part of the video but I really think getting to know what it sounds like is the most important thing... feature-wise the MIX BX is 'what you see is what you get' so there's not a lot of fancy tricks that you can pull of with it, apart from adding tons of character to anything you put through it.

correction: it is capable of amplifying line level signals to modular levels but there's no guarantee that the signal will stay clean

0:00 intro
0:31 hi
2:08 front panel features
12:55 distorted kickdrum trick
18:27 parallel saturation
24:13 no talk runthrough

I was thinking about what to type between 'MIX BX' and 'extensive playthrough' and the things that came to mind were '6 channels of bonkers', 'eurorack 90s grunge mixer', ... but none of that really serves the MIX BX justice. It does all the glue, grit and grime of the Boss BX era range of mixers, but the thing that stood out to me the most, compared to other eurorack mixers I've tried, is the amount of low end on this thing (what I would consider as 'warmth').

You can support my channel at http://ko-fi.com/BRiES - there's some exclusive content and downloads. This includes several patch breakdowns and some designs I made. There's also a seperate shop where I sell virtual instruments (ableton live) and sample packs. If you're interested in getting one on one feedback, guidance, in-depth explanations, etc please contact me at briesmodular at gmail dot com - I just started doing this 1 on 1 thing so it's still very much in its infancy. Send me a message if you're curious!

DISCLAIMER: Andrei from Feedback Modules sent me this mixer because I insisted that he should make some kind of demo to showcase the character (sound) of this mixer, since that's its main feature. I was genuinely interested in the MIX BX and I'm really happy I got the chance to make this video so everyone out there wondering about how it sounds can watch my video and at least get some idea about what it's capable of."

Feedback Modules 1 BIT MULTITAP DELAY / second patch / eurorack stereo delay

video upload by BRiES

"I wanted to upload a first patch, but that clip was too short so I uploaded it to Instagram instead (@bries_from_earth). This upload is the second patch I made. The 1 BIT MULTITAP DELAY is connected to the aux send of my mixer and I'm using both outputs as a stereo pair. There's a little bit of reverb on a seperate channel as well coming from the FX Aid.

Andrej focusses on sound and build quality and this module isn't any different. As I'm used from Feedback Modules the 1 BIT MULTITAP DELAY is very well constructed, the knobs feel sturdy, there's absolutely no wobble. The beefy knobs on this unit are just great."

FEEDBACK - 106 Chorus

Published on Mar 14, 2017 DivKidVideo

"FEEDBACK modules are onto a winner with their range of modules! Just wanted to start off by putting that out their. Not only are the Two59 oscillators and shaper killer but the range of pre-amp channel strip modules are great too alongside the utilities CP3 based mixer and attenuator / offset module. But ... this 106 Chorus does the business giving us a mono input and stereo output from an analogue chorus circuit based on (or is it exactly the same, we should ask!) the classic Roland Juno 106. It's fat and warm and the input level gives some killer overdrive too at higher settings.

The video uses Mutable Instruments Braids to give us loads of oscillator tones to throw at it before sending in some PO-12 pocket operator action from Teenage Engineering."
