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."

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."

Our system allows buttons, rotary potentiometers, fader, pressure sensitive pads, leds, encoders, sensors, and other analog devices to be connected through Livid and third party modules.

Cases

Our Elements cases come in multiple sizes, giving you the flexibility you need to mix and match modules. These cases are crafted in our Austin, Texas facility with strong aluminum and hand finished mahogany end caps. We’ve designed them with standard Eurorack sizing, which allows them to work with many existing Eurorack analog synth gear. An optional power supply panel can also be ordered to replace the MIDI ports panel to accommodate analog synth power supplies. These cases also have removable backs for easy access to your modules."

Polytik Synths Now On Kickstarter

Published on Jan 31, 2017 Polytik Synths

You might remember the previous posts on Polytik here and here. This is a project from Dirty Electronics/Mute Synth & Jack Featherstone. Below are some additional details captured for the archives, via the Kickstarter campaign here.

"Polytik is a collection of beautifully designed hand-held synth modules. Born out of a DIY ethos and the maker community, they have been crafted into something very different – a series of beautifully designed objects in their own right. We have used open-source hardware and software and encourage users to make new modules and hacks."

Playlist:
Polytik Synths
Polytik designers Jack Featherstone and John Richards in conversation
Polytik Synths x Jas Shaw

"The brainchild of John Richards and Jack Featherstone in collaboration with Artists & Engineers, these hybrid analogue/digital devices can produce a palette of sounds ranging from angular rhythmic sequences to abstract noise, pads and drones. The synths are designed to be tactile, to be held and touched when playing.

Polytik comprises four separate, colour-coded, battery powered modules. Every Polytik system needs a Core module and at least one sound module. The sound modules connect to the core with ribbon cables, these carry audio and control data to connect the system together giving you a single audio output for all modules. You can have up to three sound modules connected at one time.

The Starter Pack comprises a Core module and a Combi module, which we think is a really good way to start using Polytik.

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 ALM TV

"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."

3 Modules #1: Maths, STO, Rings

Published on Apr 15, 2017 Comparative Irrelevance

"My current eurorack setup looks like this: https://www.modulargrid.net/e/racks/v...

Disregarding the 1U row, there are 10 separate modules. This means that there are a total of 120 different three-module combinations possible with my setup. In this video series I intend to explore each and every one of those combinations.

To start it all off: Here’s a drone piece featuring Maths, STO and Rings. I’m using a feedback loop through Rings, which is in «sympathetic strings» mode, over a low drone from the STO. And, of course, Maths provides some complex modulations of the sounds.

Patch illustration: http://imgur.com/a/0hbNA

In principle, each patch will consist of only the three modules in the given combination. HOWEVER, the 1U row is «fair game». Some combinations may necessitate mixing, attenuation or an input clock signal, and this is why I won’t count the bottom row of utilities as separate modules. I’ll be happy to take requests as to which combinations to try out next."

JU60-VCF is an analog 4-pole low pass filter adaptation of Roland Juno-6/60 using a vintage IR3109 chip with a BA662 OTA chip in the resonance feedback loop. This topology was also used on the Jupiter-8, with a switch for tapping the 2-pole mode. Resonance will self-oscillate and produces a nice sine wave alone. JU60-VCF won’t turn your system into a polyphonic synth, but it has a classic sound at a sweet price.

Details on the Upcoming anAmoNo X Synthesizer From Gotharman

You've seen the videos, we now have full details on the upcoming anAmoNo X synth in directly from Gotharman. You'll find the full details on a new anAmoNo X site here, and captured below for the archives. Take a look at the specs. This is going to be one powerful synth, complete with swappable filters and more.

"Modular synthesizer with memory, swappable analog filters, sampler and granular effects.

Please notice: anAmoNo X does NOT work with the expansion box series. Instead it has replacable analog filters.

The most flexible Gotharman synthesizer ever!

I was really happy with the flexibility of my Eurorack system, but since I spend most of my time running Gotharman's, and do not have very much time for playing music, I was not really happy with the lack of preset storage on this. I always ended up spending a huge lot of time tweaking knobs and rearranging cables, and not really getting any tracks composed (inportant or not :-)). This actually became a bigger and bigger annoyance to me, and in my Christmas holidays 2015, I decided to do something about it.

At first I started to design a module with 32 audio inputs, 32 CV inputs, 32 audio outputs, 32 CV outputs, 64 knobs, a display and memory. The idea was to connect everything of all my eurorack modules to this (hmmm...actually I am not sure if this module would have had enough connections...), connect the modules via an internal cross-bay, and adjust all the CV and audio levels on the 64 knobs. It did though, pretty soon, become clear to me, that this module would be huge and really expensive to produce. On top of that, not all parameters are CV controllable on all modules, so it would require quite a bit of soldering to get this connected to everything.

So I took a few days of brainstorming with myself, and came up with a new idea: The most important sound shaping thing (to my opinion), is the filter. So if I just could scramble things a bit down, and make a box with oscillators, VCA's, modulation sources, and maybe some effect modules, and just made the filters replacable, it would theoretically give almost the same possibilities as my eurorack system, but with added patch storage. And if I one day got tired of its sound, I would just have to replace one or both of its filters, and then I would get new sounds, without having to design or purchase a completely new synth. The design of anAmoNo X began...

Super Synthesis is Shutting Down Dec 31 w/ Big Sale & Two New Modules

via Super Synthesis

"It is with bittersweet excitement I announce that Super Synthesis is closing Dec 31st, 2024. That will be right around 11.5 years, and it's been a total blast. I started Super when I was 23 years old making format-less kits and noise boxes instead of finishing my EE degree. I still am pretty sure that was the right move lol... ask again when I'm 120! I will keep supporting all of my modules forever, and the current lineup will live on as DIY kits from Synthcube, and as open source designs on the Super github. I'll probably keep putting new stuff there too as it gets finished, as open designs and synth education have been my goal and priority since day one.

On Jan 1, the Super store will close down for good. Until then, everything is discounted in an effort to liquidate stock. Right now your whole order is 40% off. If anything is left by the holidays, that discount will get deeper! I really just want this stuff in people's racks.

This is a good and happy thing. If anyone is curious about anything, starting or running or closing Super, it's one of my favorite things to talk about.

After this post on reddit, I sold out overnight:

'Enough people have reached out wanting to know about a final run or hidden stock that I've decided to try something that I've strictly avoided the past 11 years: a pre-order.

I totally want to do another run, but I can't justify buying stuff that may end up undoing the magic of selling out of my stock!

Between now (Friday night, 9/27) and a week from now (next Friday night, 10/4) I have enabled purchase of all modules (including two new modules that no one has ever seen!). At the end of the week, I'll shut down ordering and get everything made. It will take about 4 weeks to get boards made by robots and modules assembled by homie Matt (Matt rules), then I'll ship them all out. If this is too long, I understand! I think it's the only way I can really go about this, though. Since I'm going to start spending the money on production immediately following this 1 week period, there will be no refunds once it closes. If you need to cancel your order, make sure you reach out before then!

I have been working on a reverb and a chorus for the past couple of years. I love them, but funds and time and various things got in the way of actually releasing them. They're both kind of noisy, mono, sort of imperfect, and totally badass. I'll try to get some demos up, but at $59.40 ($99 at the 40% discount), you could just grab one or both and support j'boy! This reverb was a blast to develop. I got to learn all about vintage resource-constrained reverbs and came up with an original algorithm that is super tasty and useful. The chorus module is a little less exciting, I guess, but the delay time goes up to about 1/3 of a second so it's really just badass modulated delay. Check them both out:

https://www.supersynthesis.com/products/room
https://www.supersynthesis.com/products/chorus"

"ROOM is a simple reverb effect boasting much tasty character comprised of modulated all pass delay lines with high and low pass filters in the main feedback path.

FEEDBACK controls the overall feedback around the loop. At max, the verb will sustain nearly indefinitely.

LP and HP control the cutoff frequencies of the high-pass and low-pass filters in the main feedback path. Adjust LP for darker, danker, sounds. Adjust HP to remove boom, simulate smaller spaces, or create long twinkly sizzles.

SIZE controls the length of the internal delay lines. At minimum you get little cabinets or bathrooms, at max you get deep halls and spacious canyons.

ROOM is retro. It's kind of noisy. It is deliciously useful.

DOEPFER A-188-2 TAPPED BBD DELAY

via this auction
"A-188-2 is another module that is based on a so-called Bucket Brigade Device (BBD). If you are not familiar with BBDs please refer to the A-188-1. There you can find some details about this special type of circuits.

The main difference between A-188-1 and A-188-2 is the type of BBD circuit that leads to completely different module principles and sounds. The A-188-1 uses different single BBD chips with one signal input and one signal output only. In contrast the A-188-2 uses as so-called tapped BBD that has available six outputs - the so-called taps after the BBD stages 396, 662, 1194, 1726, 2790 and 3328. In the A-188-2 we use this special BBD circuit (MN3011) to obtain these module features:

The module has available two separate mixing sub-units. For both mixers the levels and polarities of each BBD output can be adjusted to obtain two different mixtures of the BBD outputs. A new type of potentiometers with center detent and center terminal is used for the BBD mixing controls to have a better feel for the neutral position. Each mixer has a wet/dry control at its output that allows choosing between the pure input signal (original), the BBD mix or anything in between. The two outputs can be treated as stereo outputs but it is also possible to use one of the outputs for other applications (details in the next paragraph).

The A-188-2 has a feedback section available that is very similar to the one in the A-188-1. But as we now have 6 different BBD outputs available 6 different feedback types are possible. The feedback input socket is normalled to the "396" output (not to "1194" as shown in the scheme, the front panel is correct). But by patching the feedback socket to any of the single output sockets another BBD tap can be used for the feedback to obtain different sounds. Even external feedback processing is possible (e.g. with a VCA for voltage controlled feedback). The feedback control has polarizer function, i.e. the neutral position is at the center. Left from the center the feedback signal is subtracted from the input signal, right from the center it's added (negative/positive feedback). Even for this potentiometer the new version with center detent is used.
A special feedback can be obtained if one of the mix outputs is used for the feedback function. In this case for each tap the positive or negative feedback share can be adjusted. This leads to multiple peaks and/or notches in the frequency response of the module.

For each tap of the BBD a separate output socket is available. These sockets can be used for changing the feedback loop - as mentioned above -, for voltage controlled mixing of the taps - e.g. with the voltage controlled mixer A-135 or other applications that require access to each single tap.

The A-188-2 uses the same high speed VCO (HSVCO) for the BBD clock as the A-188-1. The clock and consequently the delay time can be controlled manually (delay control) and by the two control voltage inputs CV1 and CV2. The sensitivity of CV1 is approximately 1V/oct. CV2 is equipped with a polarizer (a new type of potentiometers with center detent). The HSVCO has a clock output available that is normalled to the clock input socket. These sockets can be used to link different BBD modules and to run them with the same clock. But even other applications with frequency dividers (e.g. A-163) or PLL (e.g. A-196) are conceivable. A voltage composed of the manual delay control, CV1 and CV2 is available at the CV out socket, e.g. to control an external clock suppression filter as the A-188-2 is not equipped with such a filter (same as for the A-188-1)." more info on the Doepfer website.

AMSynths March News Letter

"Newsletter March 2013
Latest News: At last a new AMSynths newsletter after nearly 6 months! We can only say we have been really busy....here is the latest news and plans for 2013.

Xmas was a busy time and we shipped over 25 modules to customers and completed the design of the AM8328 Mirage Filter - which has been shipping since early January. Customer demand has increased in 2013 , so we are we have restarted our sales to the SDIY market with panels, and blank PCB's now in stock and on sale in the online store. We have also added a free online reservation system here from the web store, so customers can be sure they will get a module. Production volumes have slipped back in February due to various holidays and a busy day job, but March and April will see more modules shipping and new products arriving.

Module Plans
The popular AM8012, AM8075, AM8071 and AM8109 filter modules are in production but there is a queue of reservations to satisfy before they will appear in the online store in large volumes. The new AM8328 Miarge Filter will see another 10 modules built in March, along with the arrival of the AM8044 VCF & VCA which has cleared testing and is going into production. It is the first module we have implemented with both a filter and final stage VCA, so all it needs is a dual ADSR and dual VCO to create some fantastic sounds. A special Dave Rossum tribute VCF, the AM8040 will be launched as a PCB sets for the SDIY market initially. It will have both 2 and 4 pole modes, and can use either a rare SSM2040 chip or the HM2040 replica. If there is sufficient customer demand it will be introduced as a completed EuroRack module based on the HM2040 chip, it will have the same panel design as an AM8109 JP8 VCF and provides the sounds of the SCI Prophet 5 early models as well as the original E-mu Systems Audity 16 voice synthesizer.

The versatile dual SVF filter, the AM8060SE, is completing it's first production PCB build this weekend and if this goes ok we can start manufacturing modules for a 24 March 2013 launch. I have put some photos of the prototype on the web store, and I will add some new demos soon. The Dual ADSR AM8140 is the other product launch for late March, with a first production build to check everything is ok. Then there is the AM8005 Diode VCF to finalise on 12V and get into production, I know alot of customers are waiting on this module, so it is top of the list!

The dual VCO's remain in development with the ARP version (AM8027) about to go into a final production stage, the reason for the delay is we had to find some switched vertical jack sockets that fit the design, which we now have. The JP8 Dual VCO is at design stagee with a few more months work to get all the extra features loaded, such as the quantiszed picth knob (using a PIC) and the in-built analog LFO. The VCO designs have been switched to dual rather than single to reduce the overall costs of 2 VCO's, which everyone needs.

A set of new modules planned for 2H2013 are waiting on the arrival of the right log response vertical pots from Small Bear. This includes a dual linear and expo response VCA (AM8164) and the AM83272 Ambient VCF (using the CEM3372). The AM8706 LFO can now more forward with the right vertical jack sockets, so expect this module and the AM8019 ARP style VCA to appear by mid 2013.

Customer Feedback
AMSynths really appreciates customer feedback and ideas. Just send an email to me at sales@amsynths.co.uk. The recently launched AM8328 Mirage Filter was all down to one of our customers, Adam, asking us to make this module using CEM3328 chips. This had led onto the idea of a Key Track pot on some new modules (AM8040) which enables filter cutoff to be varied up or down by the note played on the keyboard. So do let me know of the features and modules you would like to see. For example we have new ideas floating around at AMSynths HQ, for an audio mixer, ring modulator and noise source module, which kinda replicates the middle of an Roland SH-5 (AM8002) and a programmable ADSR with 64 patches which can be voltage controlled (AM8056). And if anybody on the list writes coolt DSP code, we would love to launch a Z-plane digital filter.

Future Plans
Our biggest problem is manufacturing enough modules to meet the increasing customer demand, and that is before we do any press marketing or shows! So we are completeing reaseach into larger scale assembly and manufacturing for some modules, to see what it does to the margins and retail prices. AMSynths have launched a partnership with SynthCube, where you buy my designs in MOTM, FracRac and other non-Euro formats. The AM4023 2 pole OTA filter is the first SynthCube module to hit production, but many more will follow in 2013. The web store will move to a new platform in late 2013 to provide a better presentation and more features. We will continue to operate 2 web sites, one as a secure store and one as a blog and information portal. And Finally, many thanks to all our customer for purchasing AMSynths products and your patience in trying to buy more. I will get more newsletters out this year, timed with product launches."

This is a PCB kit for the AM8328 Mirage VCF which enables you to build a EuroRack Module with a 16-pin 12V Doepfer Bus power connector. It may also work on 15V but I have not tried it out.

The AM8328 is a 4 pole Low Pass Filter that uses the CEM3328 filter chip to produce a amazing sounding VCF.

Project Notes:

Kit Components
The AM8328 PCB kit contains:
AM8328 POT PCB (ROHS compliant, blue solder mask).
AM8328 VCF PCB (ROHS compliant, blue solder mask).
You can also purchase Pot Brackets (x7), Jack PCB and an AMSynths factory AM8328 EuroRack panel.
Kits EXCLUDE the CEM3328 chip. You will need to locate one on eBay. An Ensoniq Mirage has 8x inside."

Above: "AM8328 The Mirage Filter

This module is based around the CEM3328 4-pole Low Pass Filter chip that was released in 1984, as one of the last filter chips and with some great features. It has differential signal inputs, an accurate exponential scale over 14 octaves and voltage controlled resonance. It has a unqiue feature, the signal level is automatically increased as the resonance goes up, thereby avoiding the usual signal level dropping off as resonance comes in. The CEM3328 was late onto the analog stage, just before digital filters appeared, so it only made it into the BIT01 and Ensoniq Mirage (and a few drum machines). So this chip has never really seen action, and was never under analog pot control, just lonely digital parameter access! In the Mirage it was not even allowed to oscillate…..We just love giving it a new lease of life in a new analog module!"

Video Feedback Visualizer Modular Patch
YouTube Uploaded by ionraygun on Jan 5, 2009 (previously posted)

"I create live real-time video feedback sets on occasion and this is one of my favorite starter patches for audio visualization... wanted to demonstrate the patch while everything is still in this configuration from a New Years Eve gig.

This example uses an ebay telephone carbon microphone as an audio source going into a Doepfer A-119 input module filtered by Livewire and Plan B VCFs into an MFB VD-01 VideoScope module that is then keyed over a live video feedback signal path with a Videonics MX1 video mixer and processed by a Korg KAOSS Pad Entrancer... wow is anybody actually reading this?

Shot on a Nikon D90 for no other reason then it was handy and my Canon XHA1 is loaned out to a friend... plus who else would dare use their new DSLR for video feedback looping?

Watch in HD!"

Percussa announces beta version of SYNTHOR: digital modular synthesizer for AudioCubes

"Los Angeles, CA (USA) December 10, 2015 - Percussa announces the launch of the beta version of SYNTHOR, the digital modular synthesizer application for AudioCubes, its successful modular hardware interface for electronic musicians.

Using SYNTHOR, existing AudioCube users are no longer required to use additional software to make sounds with the AudioCubes, and musicians who haven’t discovered AudioCubes yet now no longer have to MIDI-map synthesizers to the AudioCubes to take advantage of their possibilities.

SYNTHOR is the first software digital modular synthesizer in the world with a dedicated hardware interface, allowing users to patch wirelessly by placing AudioCubes next to each other, and to change synthesis parameters simultaneously, while changing distance between AudioCubes.

SYNTHOR lets you create different configurations of synth modules, which can be saved, recalled and shared with other musicians. Imagine being able to switch modular synth configurations for every song you play live, something that is impossible to do with traditional modular synths.

In SYNTHOR, each AudioCube can be assigned to a synthesizer module (such as oscillator, sampler, LFO, step sequencer, etc). When AudioCubes are placed next to each other, connections between modules are automatically made. For example, by placing 4 AudioCubes around a 5th AudioCube, 4 connections can be instantly made. The more cubes are placed next to each other the more connections are made, all without needing real hardware patch cords.

Distance between the cubes is automatically linked to amplitude of modulation signals. By moving cubes closer to each other or further away from each other or by slightly rotating them relative to each other, the amplitude of the modulation signals can be changed. Additionally, it’s possible to sense distance from the cubes to your hands and use that distance information to change sound synthesis parameters in the modules.

Last but not least, the user automatically receives colour feedback from the cubes when assigning modules to the cubes. For example, an oscillator cube can be yellow while a noise generator can be cyan. The signal outputs of all the modules can also be linked to the brightness of the light of each cube for additional feedback, and it’s possible to mix your own colours and override the default colours.

The SYNTHOR beta is available for download in the download section of the Percussa website, and works with the recently released Percussa Wireless AudioCubes PRO as well with the older Percussa Wireless AudioCubes. SYNTHOR runs inside the MIDIBridge application for AudioCubes and requires no drivers to access the AudioCubes hardware interface. SYNTHOR and MIDIBridge are available free of charge for Mac OSX and Windows.

Percussa is working closely together with artists who provide feedback on this beta version of SYNTHOR, continuously adding more modules and rapidly releasing new versions, all in preparation of the release candidate version which is planned to be announced in the first quarter of 2016. Visit https://www.percussa.com/ to download the software and participate in beta testing.

Feedback Patching with Tape & Microsound Music Machine

video upload by MAKEN0ISE

"Pete from the Make Noise Instagram channel returns to the channel to share an uncommonly beautiful feedback patch!

Some notes:

The basic idea of this patch can be applied to any combination of modules: patch the output of one to an input on another, and then patch the output of that second module back to an input on the first. Mult and monitor one of these outputs as well and you are officially feedback patching.

This particular patch (one I find myself going back to often) centers around QPAS paired with an echo or reverb module— in this case a Mimeophon (although an Echophon or Erbe-Verb would work as well).

The types (and number) of modules you use in this feedback loop will drastically change the results, as will any parameter adjustments on either/any of the modules in the loop!

Feedback Patching is an experimental technique— embrace the uncertainty! Patch freely, experiment and have fun!

What are some of your favorite module parings to patch as a feedback loop? Let us know in the comments! Happy patching!
