M(IDI)bira

The original build
Update #1

So here’s another update to the M(IDI)bira – a kalimba (or mbira) based MIDI controller. The redesign:

  • Is still based on the Le Strum controller
  • Uses an actual kalimba bridge
  • Uses a piezoelectric disc to convert the vibrations of the kalimba tines to MIDI velocity – this allows a little more expressiveness in a user’s playing stlye
  • Is more modular, so I can make updates to specific components
  • Uses less material – 3d printing took a few hours, as opposed to days
  • Can be played by left handed people, as a tabletop device or as a guitar, and includes labels for notes and advanced chord features

Just to recap, i wanted a MIDI controller that i could use primarily for bass and pads, and that could be played in a manner similar to how i play guitar, an instrument that i am intimately familiar with. I bought the Lestrum kit a few years ago, and only got around to building it recently.
Anyway, here are some images of the process:

A Tribe Called Red Remixes Sonic Stereotypes

Sounding Out!

The Wobble Frequency2

Welcome back to “The Wobble Continuum,” a three part series here on Sounding Out!. When we last left you, Mike D’Errico had brought us to the intersection of patriarchal cultural norms, music production practices and aesthetics, and the Military Entertainment Complex. His particular focus was on the sounds and practices of brostep (be sure to check out D’Errico’s  SO!Comment Klatsch from last week on gendered sounds, too), and some of those sounds leak through to today’s post from Christina Giacona. Giacona turns her ear to the group A Tribe Called Red in order to hear how they reappropriate and redress the sounds of colonization and racism.

As the series’ title suggests, her essay entails another journey to the low end, where things will once again get wobbly.

Queer Noise

As a part of my course at the London Met, I’ve been exploring the aesthetics of noise, which includes the social contexts that give rise to a certain “noise aesthetic” that some musicians use. Through this process, I’ve also been noticing the representation of prominent LGBT artists in the experimental and noise music I listen to. Here is an incomplete list to illustrate this:

  • Genesis P-orridge (Throbbing Gristle/Psychic TV)
  • Coil (both the members)
  • Lou Harrison
  • John Cage
  • Harry Partch
  • SOPHIE
  • Cecil Taylor
  • Bob Ostertag
  • Julius Eastman
  • Xiu Xiu
  • Wendy carlos

In the artists I listed above, there are a range of ways in which this “noise” is formulated and performed – John Cage constructs performances within existing systems of chance from which music can arise – such as using the I Ching, or by tuning radios through geographically and temporally variable transmissions. Cage would probably not like the label “noise music” – but the unpredictability of the sounds that emerge through his carefully choreographed performances are nonetheless a source of inspiration for noise musicians that have emerged since. Harry Partch and Lou Harrison utilize polyrhythms and tunings that are undefined in the conventional western 12 tone harmony system. Genesis P-orridge and Coil imbue heavy drones and industrial rhythms with an erotic (and often frightening) mysticism and newer internet era artists like SOPHIE and Arca imbues their glossy hyperpop with glitch and sounds of digital failure associated with the PC music scene. 

As I seek art that I relate to in a personal manner, I perhaps create a feedback loop whereby I listen to a disproportionate percentage of LGBT musicians whose work I enjoy as compared to the average listener. Despite this confirmation bias, I don’t think it is surprising if queer people are more equally represented in experimental spaces – the avant garde is a fertile ground for the expression of the otherwise ineffable or repressed, and there’s definitely an overlap between the aesthetics of queerness and noise.

Taking a prominent queer figure as an example – Alok Vaid Menon’s aesthetic seems to verge on a simulacra of different forms, styles and identities that clash together to create something wholly new and initially (to my eyes) visually disjointed and noisy. This visual incoherence belies a deeper clarity in the message of their art – that we should be breaking assumptions and stereotypes associated with gender expression in society. Accepting the discomfort of what lies in between our ingrained dichotomies leads to a greater understanding of who we are as people. Simiarly, noise music involves becoming comfortable with a new kind of listening, and a new kind of being that involves an awareness of these distinctions of “normal” and “noisy”, and often in trying to exist beyond these distinctions.

Noise and experimental music are fairly nebulous terms that just cover everything that isn’t represented in the mainstream. Just like the word “queer”, which is (by one definition) an umbrella term covering a number of identities within the LGBTQ+ spectrum. The boundaries of these terms seem to be given definition by what they are excluded from, rather than by what they include. The forms of music considered “experimental” are always in flux, and dependent on numerous factors, from the intent of the artist to a larger narrative about their space in the world of music. I see a similarity here to the fluidity inherent in our gender and sexual identities, which are constantly evolving based on how we wish to perceive ourselves, and how society perceives us.

The playlist I shared above contains a bunch of noise music made by queer artists, covering a gamut of noise forms – generally improvisational, sometimes loud, sometimes containing distinctly unmusical sounds. But hopefully this brief sampling, will give an idea of the kind of ways noise can be used to simulate or express the queer experience, or how queerness translates into distinct noise aesthetics. 

CV Foot controller

This is something I put together to allow a user to control instruments with their feet. I wanted to control the specific interval of my EHX Pitchfork pitchshifting pedal, as well as the recording and overdub functions of my WTPA2 looper. I actually had a very specific use case in mind – to be able to record a loop on the WTPA2, and then shift the pitch of the loop by a specific pitch interval with the Pitchfork.

This was my hack – a pedal consisting of three footswitches to control the recording, bank change and overdub operations of the looper over a DIN cable, and a separate arduino controlled circuit which sent a control voltage to the pitchfork depending on the user input on a resistive ribbon.

How it works

I programmed the resistive ribbon to have 8 “zones”. Depending on which zone is touched, a different note is triggered via CV. Using the rotary selector, one can choose assign different scales/chords to these zones. For example, selecting “dom 7” would mean the user could pitch shift by any of the intervals of a dominant 7 chord: selecting the left most zone would mean no pitch shift (root position), selecting the third zone would mean a pitch shift of 4 semitones (a third), and so on. In some cases, multiple zones represent a single note, so that the player has more space for their feet.

In case all the whitener fluid didn’t make it obvious, this is still a work in progress. I plan to add the following:

  • A proper digital-to-analog converter (DAC) to make some of the code cleaner, and to make it easier for me to add features
  • An arpeggiator function
  • MIDI sync in for the arpeggiator OR MIDI CC gate outs to control VCV Rack on my laptop (I can only do one of these due to arduino micro limitations)
  • User editable scales

There were some interesting things i learnt through this project:

  • As I didn’t have a dedicated DAC at hand at the time, I used an Arduino Pro Micro to generate a 16-bit PWM voltage which varies from 0-5V. The PWM pins on the Arduino (which the AnalogWrite() function utilizes) are only 8 bit which makes assigning exact note frequencies difficult. As a result I had to use a technique to modify the atmega timer pins to output a 16 bit PWM.
  • A PWM output isn’t a smooth, continuous voltage, but dips from 0-5V in regular intervals which gives an “average” voltage output close to what you want. This control voltage can work in certain scenarios like controlling the brightness of an LED (since our eyes can’t detect a flickering greater than 30 times/second), but the voltage fluctuation is very easily registered by the expression input of the EHX pitchfork.

    In order to make this output usable, I added a simple RC filter in series with the output to smooth it out. This worked in making the voltage more stable and accurate for the intended pitch tuning purposes. It had the additional effect of adding a portamento to every note change, as the capacitor introduces a slight time-delay when it charges up. This is actually pleasant in certain scenarios, and gives a nice dreamlike “warble” to whatever I’m playing.

Boss AB-2 power mod

The Boss AB-2 is a pretty basic footswitch for switching an input between two outputs or vice versa. It has the annoying feature of being only battery powered, and that the circuit stays on as long as a cable is plugged into the “In/Out” jack – which leads to them draining out pretty fast.

In addition to this annoyance, a leaky battery that stripped paint off the enclosure. removing my dependence on batteries seemed like a relatively easy fix compared to other things in my life, so I went ahead with it. Here’s how to do it:

Witness Me!

Here is a track that emerged from the last jam I did with my DIY loopstation, before I managed to burn out the axoloti board that was central to its loop sequencing capabilities.:

It’s built around a few loops:

  • A short 4-note motif with of my guitar
  • A drum break sample from Archangel Thunderbird by Amon Duul
  • A sample of Faiz Ahmed Faiz reciting “Hum Dekhenge”. Here, Faiz recites the words in a way that fits nicely with how revolutionary the words actually are, in contrast to the moving Iqbal Bano rendition that got popularized during the anti-CAA protests.

“Witness Me!” is a call uttered by Warboys as they prepare for heroic, kamikaze-style deaths in battle, in Mad Max: Fury Road. “Hum Dekhenge” translates to “We shall witness” (this link has the full translation).

I liked the juxtaposition of these two phrases – In Mad Max, Nux acts alone, asking his peers to passively observe him as he hurtles to oblivion in the service of power and those who have it. In Faiz’s poem, the act of “witnessing” is more active – it’s a call to action to those who are denied power, towards the very clear end of attaining justice.

WIP: The Signal Mangler

This is a noise effect box for adding digital or tape emulation artefacts to an input signal in a (hopefully) musical way.

Section A (yellow knobs):

  • A simple bitcrusher/sample rate reducer circuit. This is the original design: link
  • It has a control voltage (CV) input for the sample rate.

Section B (white knobs):

  • A single-repeat envelope controlled delay delay. Based on the clari(not) pedal
  • The envelope of the incoming signal is fed into the delay time of the circuit, which can create a wide range of pitch bendy sounds. 
  • The delay time can be controlled by CV. 

I made this for a friend, and this was a little guide I prepared for him.

Instruments of Error

The “noise” produced by an instrument, once had a very qualitative meaning – it was the unusable, non musical aspect of its signal. Specific types of noise that were generated in the early days of certain music technologies often become characteristic that define certain genres. Sometimes, they frame the aesthetic of those genres –

  • The sound of “timestretching” a sample became common as samplers were used in drum and bass;
  • The use of distortion and fuzz (particularly on a guitar )in rock
  • “Scratching” in hip-hop.
  • Robotic vocals via Autotune – everywhere after “Believe

These tropes evolved in a similar fashion – practitioners began exploring the instruments of their medium, and learnt to extend their capabilities by exploiting flaws, or re-purposing features in an instruments design. Through repeated usage by the artist, and exposure to the listener, the “noise” becomes normalized to the point that it becomes an intrinsic feature of an instrument. Over time, noise in a certain context transforms to become a signal of a different one, and the instrument becomes inextricably tied to the development of an artform.

Seize the means of antiproduction

This is now a full blown aesthetic of its own right, and noise music, glitch art and various other genres have emerged over the last few decades to mirror and exploit our relationship with this technological failure.

Glitch is trope of electronic music that has been slowly entering the mainstream consciousness since it’s introduction via IDM in the ’90’s -to the point where it’s crossing over into other genres. The context in which it exists is a bit of a contrast to how “errors” that previously came to define genres came to be. To create controlled errors is a pretty difficult production job, and it requires access to fairly hi-fi production grade equipment, such as DAW’s like ableton, or samplers. This “lofi” pedal cost $369! Which creates an interesting dichotomy – that people are actually willing to spend what would be the rent of a pretty nice 2BHK house in central Bangalore on something that makes them sound (to some ears) – worse! It does seem access to a lo-fi aesthetic is now a decidedly luxury phenomenon.

While glitch may have had it’s roots in IDM and more unabashedly “electronic” music, it’s an aesthetic that’s intrinsically abstract. Since most music production now occurs on DAW’s, a glitchiness can be overlaid over pretty much any genre of music – so why hasn’t it caught on? A part of the answer lies on how inaccessible some of these tools still are to the general public, but also the aesthetic itself. It’s a decidedly hi-fi form of lofi, where even your conception, your understanding of the aesthetic is couched in a theoretical framework that requires some exposure before you truly “get it”. Sometimes, you have to get counterintuitively get accustomed to a codification of a form of noise – glitch begins by attempting to subvert expectations, but once you’ve heard Ryoji Ikeda a couple of times, you begin to know what to expect.

Another form embraces the inherent noisiness that emerges from not having access to “production grade” tools. This approach to the noise aesthetic is a reaction to the sterility of industrialized mass production of music, and uses it as a means by which to connect to listeners. This thinking is entering the design of some modern instruments. For example, Todd Bailey’s WTPA? sampler (which I use pretty extensively) is designed to exploit the digital noise that is inherent to the process of converting an analog signal to a digital one. Glitch and stutter pedals are now a dime a dozen – 1 2 3 4. All of these tools enable controlled usage of “errors” that could occur in music technology so that traditionally unmusical sounds can enter the musical lexicon.

One thing I thought that was interesting – all the key sounds I listed as being intrinsically linked to genres are now much more free to move around between genres. One narrative for the progression of 20th century Western art has been that of a a growing acceptance in including what was once thought of as culturally “noisy”. This acceptance of “noise” is immediately apparent in music. Artistic advancement in music is inextricably tied to technological and conceptual advancements in the field. In a sense, the only truly universal characteristic of any genre of music is its antithesis – noise, or something that makes you go “whatever that is, it isn’t music”. It could then become the aesthetic of music genres and movements – a type of noise – or “not music” becomes a symbol for rebellion, and over time, normalized and incorporated into the mainstream.

(This is an old piece I had written, I just thought I’d put it out there)

Here’s a lofi mix i made about a year ago with some of these ideas in mind: Experimental Hour

M(IDI)bira – update 2

I’ve been working sporadically on a better enclosure for the Mbira MIDI controller. Here’s a quick update.

  • 3D printed in translucent PETG
  • I discovered these heat inserts, which have simplified the assembly a great deal
  • Instead of the janky GI wire I was using earlier, I’m going to fit this kalimba tine kit I found an amazon
  • I’m trying to see if I can get the tines to output midi velocity – I may need to combine midi streams before the output using an arduino since I can’tmess with the Le strum code (I’d prefer not to break something).

Restricted Economies

For some of us, our existence is defined by processes that entail an excess of production when compared to how we are naturally inclined to consume, and the raw materials we have to produce with. This colossal production activity is at the control of a disproportionately small number of people,  and the control exists on many levels, extending to our psyches and imagination – well beyond the tangible processes we originally associated with production.


Seguing from that cheery intro, here is a quote from Bataille:

“…. any “restricted economy”, any sealed arrangement (such as an image, an identity, a concept or a structure) produces more than it can account for, hence it will be inevitably fractured by its own unacknowledged excess and, in seeking to maintain itself, will, against its own rationalized logic, crave rupture, expenditure, and loss. More specifically…. the term expenditure describes an aspect of erotic activity poised against an economy of production.”

Reading this (quoted in a section of Nechvatal’s Immersion into Noise), I started to think about how this relates to the idea of open source, and how open source can be a “noise” that breaks exisiting flows of control  within the restricted economy of ideas we exist within. Taking patents as an example of an existing form of control, we cansee that they aretools for codifying flows of intellectual property, often in directions that are advantageous to the entities controlling the flow. When intellectual property extends the metaphor of physical ownership into the intangible space of ideas, it disrupts the very meaning of the word – bounds are placed on what ordinarily exists outside the definition of being a limited “commodity”. This extends the concept of a present, quantifiable ownership into an infinity of possible applications of a given idea or technology. The excess here is in the desire for control, not in the means of production themselves, which are actually being limited. 

The flow can then be controlled to enable monopolies around ideas – which is what patents are set up to do. They can (for a limited amount of time) then be bought and sold like any other commodity. It is immaterial that it only takes a reasonably observant and skilled person with similar training to recreate something covered by a patent – the legal machine actively supports the creation and sustenance of monopolies. The initial intention of the law may have been to protect even smaller inventors from larger industrialists who may steal an idea because they have the means, while enabling the smaller creator to have enough control to monopolize his/her idea for their lifetime. However all this has enabled is a new breed of monopolies, where creators know how to misuse this decentralization by spreading their eggs in multiple baskets, as with the trend of tech giants developing decentralized online platforms. 

Once the metaphor has been extended, institutions and tools to enable this commodification and control, such as Sony’s DRM (Digital Rights Management), can be implemented. Our legal and economic structures are built to support this form of centralized flow of property – and this dystopia is now extending to the realm of intellectual property:

  • Youtube’s algorithm allows automated “takedowns” of videos which contain copyrighted material, but it does not recognize the fair-use laws that protect this use of content.
  • The kindle store effectively limits the ownership of any book you purchase – lending is limited as are your means of accessing the published content.
  • Aggregators like JSTOR charge exorbitant amount to access research papers that can be freely obtained from the authors. The researchers themselves rarely see this money.
  • An especially egregious example is the recent attacks on the “right to repair” that many companies such as Apple and certain automobile manufactureers are undertaking – which extends the concept of ownership almost indefinitely in favour of the company that produces a product.
  • Copyright law has been extended to 99 years (effectively indefinitely for a single generation), which means an author (and potentially his/her estate once they pass away) has default ownership over anything that even vaugely resembles their idea, as seen in a bunch of recent lawsuits.

There have been a few recent high-profile cases of mainstream corporate culture adopting public domain practices (Tesla releasing their patents, Microsoft buying Github). It’s perhaps more accurate to cynically view these actions as a form of virtue signalling – while they may signal a growing awareness of the need for public domain innovation, these would not have happened if not for other ulterior motives (marketing stunt/data collection) that exist, and are hence still firmly embedded in the current imagination of techno-capitalist hegemonies.

Open source breaks this trend by creating a break from the current means of production, by allowing for more graded variations of IP. This allows alternatives to the current centralization of power – now, the means of (intellectual) production are accessible to everyone. Instead of concentrating on control, focus is shifted back to power over the means of production. Ideas are free to be regenerated, remixed and reconstituted until they become something new and wholly detached from their sources. Indeed  the whole concept of ideas as “capital” is free to be done away with. There is no conception of loss, as the power remains in the hands of those that develop and release their inventions under public domain license – but it can no longer be concentrated there. 

I have often come across a misconception that people have of open source being inherently anarchic. This isn’t wholly true, as these licenses require strong publicly funded institutions that recognize and support them, and it is in the Public’s interest to protect these licenses. This way, when an erroneous claim is made by a third party, the onus to defend the IP no longer falls onto a single individual, who may not have the resources to do so. Additionally, as open source still allows for graded degrees of ownership, it still allows for the creation of a monopoly. These monopolies are still limited to a niche, so there isn’t a great deal of competition, or people vying to recreate a product. 

Open source licenses are not merely a negation of the concept of intellectual property, and are hence not limited by its definition. In the long run, a distributed concept of ownership (and power) can only result in more resilient, trusting communities. I am hopeful that over time societies will default to releasing work into the public domain, although I doubt this will happen without a significant rupture to our current mode of thinking. It needn’t be apocalyptic, but it is easy to imagine how this might be a possibility. Taking our current large scale environmental degradation as an example: the cornucopian would view it as only being addressable by the development of appropriate technology – however, this may only be possible with wide-scale distribution and adoption of said technology as well – something that is hard to imagine when the designs for the technology are not freely available to those who may want to implement it.

Viewing it like this enables one to reimagine the future in a new light: as inevitable as rupture may be, perhaps it can even be desirable. Intellectual property in its current imagining is an attempt to create structure around the fundamentally unstructurable – where a limited notion of control enables short term gains. A limited world view allows for you to see patterns that emerge by the virtue of its randomness, but which belies the true nature of the system that is visible upon zooming out. I don’t know what that looks like, but I’m hoping our inevitable rupture will lead us to it.
