Source code for Christmawave – overlap, duration and repetition

This is the fourth part of a series of posts about how I created my album Christmaswave. Previously, part 1 posted a list of questions and answered the first two of them: ‘What sample am I going to play?’ and ‘How many times am I going to divide it in half?’. Part 2 answered the question, ‘Once it’s chopped into little (or not-so-little) pieces, which one of them am I going to play?’. Part 3 talked endlessly in the meandering way of hangovers about playback rates.

One thing I have not addressed is how I picked which parts of source material to use. Unless the words were compelling in some way, I tended to go for phrases that were instrumental. In some songs, this left me only the intro and the outro. This is why most of the pieces have source material taken from multiple versions of the same song.

How much should an event overlap whatever comes after?

Normally, you would do this by setting the \legato part of the event, which is ‘The ratio of the synth’s duration to the event’s duration.’ I set this to 1.1 in most of the pieces, which helped make up a bit in case the slicing was in slightly the wrong place.

Most I varied:

\legato, Pwhite(0.8, 1.5)

Some depended on the duration of the it of sample I’m playing. This is what I did with Sledge Trudge

\legato, Pfunc({|evt|
var dur, legato;
dur = evt[\dur];
legato = 1;
(dur < 0.01).if({ legato = 2}, { (dur < 0.07). if({ legato = 1.5}, {legato = 1}) }); legato })

How long should I wait before going to the next thing (which might be a repetition of what I just did)?

This is a question as to what to put for the \dur part of the event, which depends on the number of frames of sample that we're playing, the sample rate of it, and the playback rate.

I pulled a lot of my source material from youtube - by using a browser plugin to download and convert to mp4 and the using audacity to convert to wav files. These files were often 48k, which is the standard for film, but audio is generally at 44.1k, so I did have to take the source file's sample rate into account.

It makes sense to calculate the start frame and duration together. This example is from Out in the Cold:

[\startFrame, \dur], Pfunc({|evt|
var buf, startFrame, dur, div, start, frames;
start = evt[\start];
div = evt[\div];
buf = evt[\buf];
frames = buf.numFrames;
startFrame= frames * (start/div);
rate =evt[\rate];
dur = (frames / buf.sampleRate) / rate * div.reciprocal;

[startFrame, dur]

How many times should I repeat this thing?

The glitchy repeating of the same event multiple times is a repetition of the entire event, not just some parts of it. I did this with Pclutch, which has a slightly weird syntax.


The pattern is just your Pbind or similar, but the connected part is slightly odd. If it's true, the Pbind is evaluated to produce a new value. It's it's false, the previous event is repeated. It's possible to use a pattern to control this.

This is the pattern I used for Walking in a Winter No Man's Land. 0 is equivalent to false and 1 is equivalent to true.

Pseq([0, 0, 0, 0, 1,
Pseq([Pn(0,2), 1],1),
Pseq([Pn(0, 3),1],1),
Pseq([Pn(0,4), 1], 1)

Starting with the Pseq means that the Pclutch will repeat 4 times, then make a new event. After that, it picks randomly from 3 Pseqs. The first repeats twice, the second 3 times and the third 4 times. It will randomly pick between these repetitions for 100 times and then stop.

Source code for Christmawave – picking playback rates

This is part 3 of a series about how I created my album Christmaswave. Previously, part 1 posted a list of questions and answered the first two of them: ‘What sample am I going to play?’ and ‘How many times am I going to divide it in half?’. Part 2 answered the question, ‘Once it’s chopped into little (or not-so-little) pieces, which one of them am I going to play?’

One thing I’ve talked about in both posts is balancing a desire for predictability in running the code and in allowing for random variation. This may seem strange for a studio album, but with my previous Christmas album, 12 Days of Crimbo, I did end up playing one of the pieces, Little Dubstep Boy live at an algorave in Birmingham, so it is possible some of these pieces may have a live afterlife.

Perhaps more importantly, allowing for variation allows the discovery of good juxtapositions, which can be made more likely in subsequent revisions of the code. It also makes making the pieces themselves more interesting. Listening to the same thing over and over again in a DAW can get tedious, but subtle changes give something to listen carefully for, keeping one’s ears fresh. I have way more skill in coding pieces than trying to piece them together manually and allowing randomness is an important part of my process.

What speed am I going to play the next bit at?

Having decided which sample to play, how small to chop it up and which subsection of the sample to play, the next question is what speed to play it back at. This is a question the rate at which I playback the buffer, such that both speed and pitch are effected.

A lot of the Vaporwave I’ve listened to seems to play back their samples at slower than the original speed. It also sometimes switches speeds, so that both pitch and timing jump. I like this effect and chose to copy it.

I thought of the timing changes in terms of scales. In Just Intonation, scale steps are given as fractions between the ratios 1/1 and 2/1, where 2/1 is one octave higher than 1/1. Because I wanted slower speeds, I adjust downwards, so that the ratios I used were either between 1/2 and 1/1 or between 1/4 and 1/2. These ratios can then be used directly as the rate parameter in a ugen.

Obviously, almost all of the source material is in 12TET – that is to say: 12 tone equal temperament, the tuning one finds across the white and black keys of a standardly-tuned piano. Any tuning I apply on top of that is more or less in conflict with the original. This can be minimised by only using one rate at a time and repeating it across several subsequent bits. By sticking to one rate for a while, a change later on becomes roughly analogous to a key change. It would have been possible to have a set of sensible key changes that work with the standardised harmony conventions of the original song, but this is not what I did.

Long story short: I picked some scales and tunings

The first piece I worked on, Have Yourself a Scary Christmas is based on Have Yourself a Merry Little Christmas, sung by Judy Garland. That piece and especially that performance of the piece has quite a bit of emotional complexity. The ambiguity of the piece is apparent even in the title, which is not ‘Have a Merry Christmas’, but a more emotionally strangled ‘Have Yourself a Merry Little Christmas’, like someone trying unsuccessfully to be friendly to an ex they’re desperately not over. The music itself is ambiguous about whether it’s in a major key or in it’s relative minor. Garland’s performance adds to this further, soundling slightly drunken and sliding the tuning around in a way that sounds like she’s papering over crushing unhappiness. This effect is especially apparent if you listen to the song slowed down by a factor of 4 with Paulstretch.

In order to draw out the sadness a bit, I used a Romainian minor scale. This is part of the included scale library that comes with the SuperCollider Scale object. I then randomly picked ratios from the scale.

\scale, Scale.romanianMinor(\just),
\rate, Pfunc({|evt|
var scale, degree, rate;

scale = evt[\scale];
degree = (Array.series(scale.ratios.size, 0, 1) ++ [0, 0, 0, 0, 1, 1, 1, 2, 2, 3]).choose;
rate = scale.ratios[degree] * [0.25, 0.5, 0.5].choose;

Support for scales is built into Patterns, but it’s most commonly used to compute frequencies, not playback rates.

Almost all the pieces I made used minor scales. I used trial and error to pick which scale worked best with which samples. For all the pieces, I picked degrees randomly and never used anything like a Finite State Machine or a random walk, even those are usually well-suited to picking scale degrees.

In most pieces I repeated the chosen rate, using Pstutter. This is code from Santa Loves You:

\scale, Scale.hungarianMinor(\just),
\degree, Pstutter(8, Pfunc({|evt| evt[\scale].degrees.size.rand}),1),
\rate, Pfunc({|evt| evt[\scale].degreeToRatio(evt[\degree])}) * (2/3),

The Pstutter on the scale degree repeats the degree 8 times before picking a new one with the Pfunc. The rate is calculated from the degree. Because this piece uses voices, I’ve decided to stay closer to a normal playback rate. Using 2/3 instead of 0.5 or smaller means that the samples will sometimes play out faster than their original pitch.

Source code for Christmawave – what segment do I play next?

Previously, I talked about the method I used for creating the Christmaswave pieces and the issues this raises. My last post answered the questions ‘What sample am I going to play?’ and ‘How many times am I going to divide it in half?’ and, alas, the answer for the latter of those was hopelessly over complicated. Doing everything in terms of powers of two was not always a good approach, even for this project. Some songs are in 3/4 time and won’t do well with these divisions. Also, a lot of Christmas classics are performed in a jazz style and thus have a strong triplet feel. Play any Bing Crosby Christmas song at 1/2 speed and the swing becomes extremely apparent. It becomes ludicrously strongly swung at quarter speed. Well, get back to these issues a bit later on.

Once it’s chopped into little (or not-so-little) pieces, which one of them am I going to play?


Over the course of the album, I tried a few approaches. For several of the songs, I just picked randomly. This did work, but this means that some runs of the code come out with much better results than other runs of the code. Random number generators in The Santopticon (He Sees You) meant I had to try recording that piece 14 times before I found the version I wanted to use.

In order

Another approach I used was to start at the beginning of the sample and move towards the end of it. This copies the arc of the original and makes the playback/recording more reliable, although it does remove some opportunities for serendipity.

this is the code I used for Der Tannenbaumherumtanz:

\env, Pseg(Pseq([0, 1]), 200),
\start, Pfunc({|evt|
var frac, start, div;
div = evt[\div];
frac = evt[\env];
start = frac * evt[\div];
start = start.asInt;
"div is %, start is %, frac is %".format(div, start, frac.round(0.001)).postln;
}) + Pwhite(-1, 1),

\env has a value in it that goes from 0 to 1 over 200 seconds, which was the length of this section.

\start holds the number of the division to start on – for example, if there are 4 divisions, it might hold 0, 1, 2, or 3. It computes this by first getting the \div, computer previously in the event. Then it looks at \env, which, as it goes from 0 to 1, is a fractional representation of how far we are through the section. A quarter of the way through, it should be 0.25. At the half way point, it should be 0.5, etc. It puts this in the variable frac.

I multiplied frac by the number of divisions. Then, because this number will always be a fraction, I convert it to an integer, so as to get a good index number. This rounds it.

Finally, in order to make this slightly less predictable, I take the result of that calculation and subtract 1, do nothing or add 1.

Random Walk

In Lettuce, No, I picked a section adjacent to the one just played. This tends to meander around the middle of the sample, but the content of the neighbouring divisions are always related to each other, so the results tend to sound good without being too predictable.

\start, Prout({|evt|
var div, start, pos;

pos = 0; // starting position{

div = 2.pow(evt[\pow]).asInt;
start = (pos*div).asInt;

// figure out pos for next time
pos = start + [-1, 1, 1].choose; // tend to increment
pos = (pos/div).abs.min(1);

evt = start.yield;

The Prout returns the start index, but also, while doing so, computes the position. This position is a fraction, like \env above. However, instead of moving from 0 to 1, it meanders around, tending to move towards 1.

It does this calculation based partially on the number of divisions. So if the sample is cut in half, it will tend to jump from 0 to 0.5 in a single step!

The pos must be between 0 and 1, so it takes the absolute value and then compares it to 1 and takes whichever of the two values is smaller.

It would have been possible to do this in a way less dependant on the divisions, for example, by deciding the position should be an integer between 0-127 and then computing a faction based on that. This would meander quite differently as it would be freed from the divisions actually used in the piece. I have no examples of this approach from this album, but will give it a try the next time I’m cutting samples!

Source code for Christmawave

If you follow my podcast, you’ll note I put out a vaporwave-ish Christmas album, Christmawave. It’s a free download on Bandcamp, but I’m asking those who can afford it to donate to the Hackney Winter Night Shelter.

Almost all of the pieces are constructed using variations on one algorithm. I found hoary, old baby boomer Christmas favourites and then took the instrumental sections, which was sometimes just the intro or the outro. All of the songs were in 4/4 and most of the instrumental parts where cut into either in 2 or 4 bar phrases. This means every sample is divisible by many powers of 2 and can be cut in half several times before it loses musical/rhythmic meaning.

I made these cuts, played the section of the sample with some stuttering and then went on to another section of the sample. This method requires some decision making:

  1. Which sample am I going to play?
  2. How many times am I going to divide it in half?
  3. Once it’s chopped into little (or not-so-little) pieces, which one of them am I going to play?
  4. What speed am I going to play that bit at?
  5. How much should it overlap whatever comes after?
  6. How long should I wait before going to the next thing (which might be a repetition of what I just did)?
  7. How many times should I repeat this thing?

All of the pieces answered these questions in slightly different ways. (Or very different ways, in the case of question 1!) Some of the structuring of how I thought about these questions and how I solved them have to do with how the Pattern library works in SuperCollider.

What sample am I going to play?

In almost every case, I switched samples based on how much time had passed since the start of the piece. I used Ptpars to start different sections.

How many times am I going to divide it in half?

Another way of asking the question is, ‘what power of 2 am I going to use?’ I did this a few different ways. In most cases, I stuffed this into part of the event I called pow. Here are some ways I figured out what power of 2 to use:

\pow, Prand([0, 0, 0, 0, 0, 1, 1], inf)

Then later, on I could go from that to powers of two:

\div, Pfunc({|evt|

(Usually, I would compute the \div in a larger Pfunc that figures out more things.) The advantages of figuring out the power of 2 instead of just having a Prand full of 1, 2, 4, etc are that this is harder to screw up. I don’t need to worry about a stray 3 sneaking in, and, if a sample is longer, I can add some number to the \pow to make the \div bigger.

Another way I computed the \pow was using a Finite State Machine. This was completely overkill, but I’ll walk you through how it worked.

What I wanted was to have a possibility of a \pow being as small as 0 or as big as 8, but not to jump from one of those numbers to the other. Instead, I wanted a route going through intermediate numbers, in which it could potentially get to an 8 and have a path back to 0. I wanted a way for it to wander from one extreme to the other.

A FSM offers a way to give a path. This is what the code looks like from Funky (The Slow Jam):

\pow, Pfsm([
#[0], //start
2, #[3], //0
Prand([0, 0, 1], 1), #[1, 2], //1
Prand([0, 1, 2]), #[1, 2, 3], //2
Prand([1, 2]), #[3, 4], //3
Prand([0, 1, 2]), #[3, 5], //4
Prand([2, 3]), #[4, 3, 5, 6], //5
Prand([3, 4]), #[4, 3, 5, 7], //6
Prand([3, 4, 5]), #[4, 3, 5, 6] //7
], inf),

Pfsm is the pattern library that does state machines. It takes an array. The first item in the array is an array of what states it can start with. Next comes pairs. Each pair is a state. The first pair is state 0. The second pair is state 1. The third pair is state 2, etc. The first item in a pair is the output. In the example above, the output of state 0 is 2 and the output of state 1 is Prand([0, 0, 1], 1).

The second item in the pair is an array of one or more integers. The numbers in the array are the states you can go to next. So with state 0, the array is ‘#[3]’, so it goes on to state 3. When it gets to state 3, it produces the output, which is Prand([1, 2]) and then looks where it can go next, which is ‘#[3, 4]’. That is, it can go state 3 again, or it can go on to state 4.

I could draw a map of this (which would reveal that there is no path to states 1 and 2 – oops).

The FSM described in the code above
In the graph, you can see a lot of arrows pointing up and few pointing down, only along a path that goes through all the states. Thus, it’s relatively unlikely to reach state 7.

Because Pfsm is just another pattern, I could add 1 or 2 to the output of it in the case of a particularly long sample and it would gracefully handle the maths.

Answers to the other questions will be forthcoming in following posts!

The Dead Shopping Mall Project

For various regions, shopping malls across America (and in other places) are dying. Many have only a few shops left in them. A few, somehow, manage to thrive.

Many Gen-Xers spend their formative years in shopping malls, walking endlessly in circles. The experience of these malls was not only a visual panorama of their shiny flat surfaces, but also very much their acoustics. The indoor stores separated themselves from the indoor mall by using piped in music, which informed shoppers that they were entering a different space. The music used was chosen to signal what demographic the store hoped to attract. Stores for teens played the top 40 that appealed to that age group.

Department stores and the mall itself played more neutral music, trying to signal a more broad appeal. All of this was set in space full of talking, foot traffic, and young people, set against very reflective surfaces. It was not just the music chosen, but the acoustic that differentiated spaces.

Smaller stores had nearby walls, dampened with hanging clothes or other wares, and thus their reflections were different than the more open mall.

As malls disappear, their unique sonic environment disappears also. It’s impossible to recapture what they were like when filled with people, unless you somehow entice people to come in. But the echoes of the sonic space and the dimensions of the architecture can be archived in a form that’s usable for people who would like to experience what being in such a place sounded like.

This usable archive can be made via a short audio file called an Impulse Response. It is a recording of the echoes of the space. Below, you can find instructions on one way to make such a recording.

These recordings should be made, as a form of acoustic ecology and of memory. So the sounds can still be used even as the spaces themselves vanish.

How to take an impulse response with two mobile phones.

  1. You will need software for your computer: audacity and fscape
  2. You will need to decide which of the phones has the better microphone. Put a good-quality audio recorder on it. This is your recorder-phone.
  3. Put this audio file on to the other phone. This is your player-phone.
  4. Before you head to the mall (or whenever you switch phones), take a calibration recording.
    1. Play the file from the player-phone while recording it with the recorder-phone. Hold the recorder-phone so it’s microphone is as close as possible to the player-phone’s speaker.
    2. Always record at the best possible settings. Try to use a non-compressed file format like WAV or AIFF.
    3. Make a note of which file is your calibration recording.
  5. Go to the mall and pick out what spaces you would like to take an IR in, then take them.
    1. Decide how far away you want the two phones to be from each other. If the phones are further apart, you get more of the sound of the space. If they’re closer together, the IR will be more intimate. If the spaces is noisy, it might be hard to record at further distances. (If you’re unsure or want options, you can do recordings at multiple distances.)
    2. Play the sound from the player-phone while you are recording with the recorder-phone. Always record at the best possible settings and try to use an uncompressed file format like WAV or AIFF.
    3. Make a note of what mall that you’re at (ie ‘Valley Fair, San Jose, California’), where in the mall you are (ie ‘food court’) and an estimate of the distance (ie ‘2 meters’). Make a note of which recording you’re referring to (either by writing it down or editing the file name).
  6. When you get home, transfer all the recordings to your computer. If you have not already given them descriptive names (ie: ‘ValleyFairFoodCourt2mRec.wav’), do so now.
  7. Open your calibration recording in Audacity, normalise it and reverse it. (These options can be found under the effects menu). Then export it as ‘callibration-rev.wav’. (Export is under the file menu)
  8. Repeat the following process with all of the mall recordings you made:
    1. Open the recording in Audacity, and normalise it. Export it with a descriptive name (ie ‘ValleyFairFoodCourt2mNrml.wav’)
    2. Open Fscape. Under the menu ‘New Module’, select ‘Spectral Domain’ > ‘Convolution’
    3. For the input file, select the mall recording
    4. For the ‘Impulse Response’, put the reversed calibration file, callibration-rev.wav.
    5. Give the output file a descriptive filename (‘ValleyFairFoodCourt2mConv.wav’)
    6. Select Render
    7. Open the output file in Audacity. In the middle of the file, there will be a loud part. Use your mouse to select just the loud part (zoom in to get it as tight as you can. If there’s a bit of lead in and a bit of fade-out, get that too).
    8. Hit the ‘z’ key to slightly adjust your selection
    9. Under the file menu, select ‘Export Selection’. This is the finished impulse response! Give it a descriptive file name (‘ValleyFairFoodCourt2mIR.wav’)
    10. You can erase your source files when you’re done if you want. Be sure not the erase the reversed calibration file until you’ve created all the finished IRs
  9. Now that you’ve got the IRs, please send them to me! Or, better, post them to and send me the links.
  10. You can use them on recorded audio to make it sound as if it took place in the mall! If you have reverb software, you can use the IR you just made as the IR, or you can use Fscape. Do a convolution with your source file, using the IR you made as the Impulse Response. The output will have the sonic characteristics of the mall!

Teach about trans people

In our current political climate, I think it’s important for teachers and academics in every discipline to take a stand in favour of diversity and inclusion. One important way we can do that is to highlight contributions in our field by members of minority groups. One way into this in any discipline is by including some history. So in computer science, teachers could mention that Alan Turing was gay and that Grace Hopper, inventor of the compiler (and, indeed of the idea of compiling), was a woman.

When teaching music and presenting a piece of music to students, I give a few biographical notes about the composer which are mostly related to their musical background and influences. This is also a good time to mention any minority status. This is important because students will otherwise tend to assume that everyone is a cis, straight, white man. It can seem a bit weird to mention that someone is gay, for example, without other context. There are a few ways to address this.

If a person’s minority status is known to effected their opportunities, then this is is a good way to bring it up. To take an example, Milton Babbit was going to be the first director of The Columbia-Princeton Electronic Music Center. When they realised he was Jewish, they rescinded the offer and hired someone else. After a year, they came back to Babbit and re-offered him the job. It’s good to tell students about this and condemn it, to let them know that discrimination was more recent and widespread than they may have imagined and to give the idea that it was wrong and should be opposed.

Another way to bring up somebody’s status as a minority applies if they were a member of a milieu at least partly defined by minority participation. So, for example, a lot of jazz musicians are black and, indeed, some American forms of free improvisation were called “black music”. In general, mentioning milieus is good because it gives students a sense of larger scenes and places they might do additional research. It also communicates that minority involvement was significant and larger than the few individuals discussed in class.

Otherwise, a way to bring up a person’s membership in minority groups is to just tell students you think it’s important to mention it so they know the field is diverse. This is also good because it demonstrates that inclusion is valuable.

It’s important not to make somebody’s status as a minority the defining thing about them. They’re a topic for the class because they relate to the subject the class is covering, not because they’re a minority. One must strike a balance so as to communicate that minorities have historically been part of a discipline and contributions are important and will continue. Over-emphasising their minority status can backfire and make it seem like they’re being highlighted for being weird and different. I try to bring minority community membership up just once and then not mention it again unless it’s relevant in their work.

With contested identities, such as trans people,talking about their background models how to speak respectfully. It’s important that if a student starts giggling or otherwise treating this as a joke, that they’re told to stop. Here is a guide for how to talk about trans people in the classroom.

  • If the person is not living, you should definitely mention that they were trans.
  • If the person is living, you can only say they were trans if the person has consented to this by being public about their trans status.
  • If a person has transitioned to being a woman, the term to use when talking about them being trans is “trans woman” and the pronoun to use is “she”. If they have transitioned to being a man, the term to use when talking about them being trans is “trans man” and the pronoun to use is “he”. If someone has transitioned to a non-binary gender identity, the term to use when talking about this is “enby” (which is a pronunciation of the initials N.B.) and the pronoun to use is “they”. In every case, if the person has expressed a different label or pronoun, you should follow their preferences.
  • Always use their current pronoun, no matter when in their life you are speaking about them.
  • Do not bring up somebody’s previous name without a good reason. Mention it as little as possible.
  • If any of this makes you feel awkward, practice this part of your classroom presentation on a friend until you feel normal about it.

To give an example of how I might talk about this:

Wendy Carlos has done a lot of work on spatialisation and has some good blog posts about it – I’ve put the links on Moodle. She is an American composer who started out at Columbia-Princeton, but then went in a less experimental/more popular direction. She’s best known for working with Moog synthesiser and worked directly with engineers there to design modules, which she used to do several film sound tracks, including Tron and A Clockwork Orange. She initially made her name with Switched on Bach which was a recording of Bach pieces done on synthesiser. This album was hugely popular, made her famous and made a lot of money. She used some of the proceeds of the album to fund her transition, which she kept secret for nearly a decade- dressing up as a man when she appeared publicly because she feared discrimination. Fortunately, when she finally did disclose in 1979, nothing much bad came of it, but it must have been miserable to spend so many years in (reasonable) fear of a backlash.

The popularity of her work shows a strong popular appetite for new timbres, but in a familiar context, like Bach. We’re going to listen to a piece by her …

When you’re talking about a member of any minority group, it’s best to assume that at least one of your students in a member of that community. the intent is to be respectful and to make that student feel included, while at the same time giving other students the idea that members of this minority groups belong in their field. Never be neutral about discrimination.

It’s impossible to get this right every time. Sometimes talking too much about discrimination can traumatise the students who also experience it, or glossing over it can fail to condemn it forcefully enough. The important thing is to keep trying to include this and to get a feel for the students you’re teaching, as every group and every institution will be different. You may find, for example, that student comments about works by women tend to be more negative than works by men. One way you might address this is to present the works first and ask for comments and only talk about biographies afterwards.

Keep trying things out. We can make a positive difference in our teaching, no matter what our subject it.

Militarised Police

In his drive to undo every single Obama policy, Trump has lifted restrictions on police getting military combat gear. This ban was put in place after images came out of the militarised response to protests in Ferguson. The problem with police having military gear is that they will use it in interactions with civilians.

Without a doubt, this is a national issue. However, it is also a local issue. Every police force has it’s own rules about what it can and can’t purchase. Your city can direct it’s police not to buy military hardware.

Many cities are organised into districts, so that every district elects a council member. I used google and my city’s web pages to find my district and from there, found the phone number for my council member’s office. The following is roughly what I said:

Hello, I am a registered voter in [District X] and I’m calling because Trump has just lifted the ban on police forces acquiring military hardware. I’d like to ask that our city police do not get an military equipment and get rid of any military equipment that they might already have.

I vote in Berkeley, and the person answering the phone had not heard of the new rules and was unhappy to hear of them. She assured me that my council member was in agreement and expressed hope that the whole council would feel similarly. It may seem like it’s unnecessary to make this call in Berkeley, but my concern was that some people might think that military kit would be an appropriate way to respond to the fascist violence that’s been rising in the city. However, I would argue that the danger of fascism is part of why we must ensure our police are de-militarised.

Because local politics are smaller scale, our voices are much more easily heard than they are in national politics. Calling about this issue can help make a difference in your community. Moreover, this does have a national effect. Cities refusing this hardware will help repudiate Trump. And keep our cities safer from police overreaction.

Tell congress you’re against nuclear war

Dear [Congress Person],

The constitution states that war can only be declared by congress. Launching a nuclear first strike is certainly an act of war. I urge you and members of congress to make clear your necessary role in declaring war and to remove from the president the ability to make unauthorised first strikes.

Best Regards,

[Your name]

[The address at which you are registered to vote]

You can fax your senators for free: You do not need to create an account, but you do need to enter your email address. You should contact both senators.

You can also fax your representative for free: You only have one representative. You can find out who they are here:

If you are a US resident who cannot vote, you can, of course, still contact your local senator and representative. If you cannot vote in the US and do not live in the US, you should contact your local government representative and express your concerns. Especially if you government is a NATO member or allied with the US in some other way, this could be helpful.


There’s already a bill in congress on this topic, the Restricting First Use of Nuclear Weapons act of 2017. Here’s a sample phone script if you want to call congress:

Everybody’s Free to Feel Good: Gay Clubs and Liberation

Listening to club mixes on Gaydio, I was struck by how often the word ‘free’ came up in the music, as a long, held, emphasised word. While some of this is undoubtedly due to the lure of endless granular stretching of the ‘eee’ sound, this is clearly an idea that resonates still within the gay club scene. For example, in Outrage’s 1996 hit, Tall N Handsome a low-pitched voice first says ‘I’m looking for a good man’ and then sings, ‘He’s got to be tall n handsome. and he’s got to be free.’

But what does it mean for the good man to be ‘free’? While an obvious interpretation would be ‘single’, when this song is played in a long set of club mixes, a more clubby interpretation of ‘free’ is suggested.

Although by 1996, gay men in England, where the song was recorded, had more freedom than previously, they still had much less than straight people. The song itself, however, is not a strident call for freedom or action. Freedom is an individual project – the good man must be free as a pre-requisite for the narrator. Again, the precise meaning of this is not specified, but the onus for attaining this freedom is squarely placed on him. Indeed, the vocal tones of the man-seeker suggest a political safeness. The spoken part sounds theatrical and light, as if they were spoken by a dame in a panto. The speaker says ‘Now, I’m looking for a good man, but not just any man. He’s got to be someone special.’ And then, as far as I can tell from the recording, he says, ‘Someone in like Popye.’ The sung part follows.

The version of this song that I heard twice on Gaydio yesterday, mixed by Paul Morell, removes a lot of the comic ambiguity of the original. The original narrator is replaced by Boy George who sounds more typically like someone speaking over a love song, says, ‘Now, I’m looking for a good man, but not just any man. He’s got to be someone special. Someone who can light my fire.’ Of course, it’s possible that the lyrics are actually the same in both versions, but of the two, the newer one is clearly intended in earnest. The update suggests that some took the original song seriously from the 90s.

The repetition of the good man’s requirements, centres the importance of his freedom – a long held word at the end of the chorus. The good man’s individualised freedom, in a 90s context, may refer to a personal authenticity. A free gay man then was free of the closet – at least some of the time in at least some circumstances. This suggests he does not have a woman in his life acting as a ‘beard’ – he’s not married nor in a sham straight relationship. As to his outness more generally, then, as now, people make choices about how gay they feel they can act in various circumstances. I’m reminded of a shop in San Francisco’s Castro District in the 1990s called ‘Does Your Mother Know?’ Like the original song, this uses humour to get at a truth. Many gay people at that time were not out at work and had not told all or sometimes any members of their birth family. The freedom required was likely not this kind of political freedom – instead the good man was somebody who was liberated in certain circumstances.

I remember stickers and chalked slogans (again in California) from the mid 90s which said variations of ‘free your mind and your booty will follow.’ At the time, I took this to mean that free-thinking would lead broader horizons in one’s physical circumstances, but other interpretations are possible. One’s booty is, of course, one’s arse. This can be used to mean one’s whole, grounded physical self (‘get your ass out of here’), or it can refer more specifically to one’s undercarriage (‘shake your booty’). Another interpretation of the slogan is that a free mind will lead to a sexual freeing. It’s likely that the narrator wants somebody who is tall and handsome and who is not overly sexually inhibited.

However, the word ‘free’ is not unique to this song. Someone at a club would hear it several times in several songs over the course of an evening. The type(s) of freedom and paths to freedom may lead towards sexual openness, but that is a destination, not an origin. Indeed, given the distinct lack of personal freedom most gay men experienced most of the time, they could only be free in safe, gay spaces. Freedom thus comes from the club.

This extremely personal sense of release and liberation – a temporary reprieve from a hostile outside, is exhilarating. The club offers a chance to be as gay as one wishes to be, without significant risk. This is in stark contrasts to public outdoor spaces, which were really only safe on Gay Pride Day and sometimes not even then. Freedom in the club and the bedroom gave one enough space to exist and to live. It called for celebration and repetition in song.

However good it felt, though, it contained an inherent contradiction. Someone who was actually free, as this is understood in straight society, would not need to rely on clubs and bars to experience their freedom. Therefore, freedom while it is celebrated is also redefined to fit the circumstances. In 1991, Rozalla released the prototypical anthem to the freedom of the club, Everybody’s Free (to Feel Good). The chorus of the song lingers on a long held ‘free’, resolving with the less prominent but still affirming parenthetical. This is not a freedom of the mind, but a physically embodied sensation of drink, drugs and dance.

The circumstance and ritual of the clubs and bars does not lessen the temporary sensation of freedom, quite the contrary. The transient nature of the experience makes it al the more compelling, as the feeling of camaraderie, community and sexual possibility relies on physical access to the space. For decades, activists complained that most gay people were only interested in this temporary freedom and not doing the work to secure a more enduring political freedom. These spaces, however, provided a launchpad for gay culture, like the charting Tall N Handsome to enter straight spaces and slowly normalise the idea that a man might be looking for a good man who is tall, handsome and free.

Domifare – still a rough draft

Today’s diff. Everything compiles, but most things aren’t tested!

Today, I wrote the functions for most of the language structures, except the scheduling ones. And the shaking one, which I’ve just realised I’ve forgotten to include! For the variable classes, I am borrowing a lot of code from DubInstrument in AlgoRLib. Probably, this project and that should be folded into one repo or one should directly depend on the other.

For DubInstruments, asking for a random pattern can trigger the creation of a new one, but not here, as all patterns are entered by the performer.

I need some GUI, including sliders for thresholds and a text print out of entered stuff. Ideally, there should also be a record light for when the performer is entering loops.

As far as shaking goes, that’s sort of straight forward for the rhythm lines. For the melody lines, I might be looking at BufferTool. It’s designed to split up spoken text rather than played notes and relies on pauses. Another possibility is to keep onset data for melodic loops and use it to decide where cuts should be. I’ll need another trigger that gets sent by the recording synthdef when it’s gate opens, so I can relate the onset timings to the position in the buffer.

Tomorrow my wife is having a party and I’m doing marking on Monday and Tuesday, so it might be a few days before I can test properly.
