).play(protoEvent: samplerEvent); See Literals for information.. For handling multidimensional arrays, there … Here we will look at these in some depth: The play synth Basics The very basics of the play synth has been covered briefly in the player object intro section but will revisited here. \decayScale, Pseq([6, Pn(1, inf)], 1), Environmental variables are not necessary, although they can be useful, and this book will not use them extensively. The final thing we need to learn in this chapter is looping. This demonstrates what a minimal amount of musical material can … See /usr/share/SuperCollider/Help/MIDIFile/MIDIFile-samplepatches.rtf for example usage. Say we want to generate 1000 synths at once. p.stop; \dur, 1 \amp, 0.2, So in a C scale, 0 would be C, 2 would be D (two half notes above C), 3 would be E flat, and so on. "done recording".postln; }); In the Pattern library there isn't a defaulting to 'loop'-based musical structures as is the default in DAW environments such as Ableton live. SynthDef(\multiSampler, { |out, bufnum, bufBase, baseFreqBuf, freq = 440, amp = 1| SynthDef(\sampleSource, { |freq = 440, bufnum| The primary goal of this residency is to explore … { ExpRand(400, 1600) } ! buf2 = buf1 + 1, This spans one bar = 4 beats, so the duration of one beat is 2.781356 / 4 = 0.695339 seconds/beat. For checking references to a method (which classes support it), type Shift + Apple + Y - poll, UGen.dumpSubclassList // UGen is a class. If you need to use frequency in Hz, use this function in place of indexInBetween.f = { |val, array| DetectSilence.ar(sig, doneAction: Done.freeSelf); basefreqs = Index.kr(baseFreqBuf, [buf1, buf2]), The above code will work in Java, C, JavaScript and many other languages. var initPulse = Impulse.kr(0), It will introduce the basic concepts needed for further exploration and it will be the only silent chapter in the book. They are used to encapsulate algorithms or functionality that we only want to write once, but use in different places at various times. inf), So in SuperCollider we can simply do: On Fedora Linux, use MIDIFile.sc(installed in /usr/share/SuperCollider/Extensions/MIDIFile/ by Planet CCRMA package supercollider-midifile). For example: if it is raining and I’m going out, I take my umbrella with me, else I leave it at home. \decayScale, 0.1, originalTempo = beatsInLoop / (end - start); Now is the time to dive into making sounds and explore the synthesis capabilities of SuperCollider. if( hungry, { eat } ); You can see that true and false are keywords in SuperCollider. Note that of course the values in the string (inside the quotation marks) could be anything, we're just posting now. We could represent those values as MIDI notes, where 60 is the C note (~ 261Hz). Many SC users go straight into the documentation when they start writing code, using it as a template and copy-paste the examples into their projects. Additionally, it will add an iterator. }); Note that the • sign is where the interpreter finds the error. This is where we can store bunch of data (whether pitches, scales, synths, or any other information you might want to reference). The ‘m’ array is still intact: you haven’t scrambled that one, you’ve simply said “put a scrambled version of ‘m’ into variable ‘x’.” So the original ‘m’ is still there. You can now change the value of the variable to something like 500, and it the frequency will ‘automatically’ be turned into 500 Hz in the left channel, 502 Hz in the right, and the cutoff frequency will be 2000 Hz. if( condition, { then do this }, { else do this }); From Wikibooks, open books for an open world < Designing Sound in SuperCollider. (Those frequencies would be passed to the oscillators as they are expecting frequencies and not MIDI notes as arguments). SinOsc.openHelpFile, https://en.wikipedia.org/wiki/Object-oriented_programming, For checking the sourcefile, type Apple + i (or cmd + i) when a class is highlighted (say SinOsc), For checking the implementations of a method (which classes support it), type Apple + Y - poll. b = Buffer.allocConsecutive(~midinotes.size, s, 44100 * 2, 1); Comments are information written for humans, but ignored by the language interpreter. To avoid this, either use Node objects (which use the default node as their target) or (when using messaging style) use a target nodeID of 1. fork { Let’s open up this input channel, by drilling a hole into the black box, and let’s name this argument ‘freq’ as that’s what we want to put in. Synth(\sampleSource, [freq: ~midinotes[i].midicps, bufnum: buf]); This class is the information needed to build the car. True is associated with 1 and false with 0. ... (s. sampleRate / s. options. }; p = Ptpar([ You can call the arguments whatever you want of course. ( Or to use an analogy: let’s say we have a class called Car. SynthDef(\sampler, { |out, bufnum, freq = 1, amp = 1| It’s enough to know where to fill up the beans and water, and then how to operate the buttons of the machine (strength, number of cups, etc.). Should I make a Synth-making function and use that inside the routine's loop? if(div == 1) { i } { \instrument, \bell, The Large Hadron Collider (LHC) is the world's largest and highest-energy particle collider and the largest machine in the world. Frequency is controlled by the rate parameter. Because you can’t reverse a number. Workshop An Introduction to SuperCollider SuperCollider is an open-source media programming language that can be used for sound design, generative composition, performance, … If the loop boundaries are wrong, then the musical result will not make sense. You use it to add something to the end of a string. The key point is that you don’t need (or want) to know precisely how all this happens. p.stop; We will explore this later in the chapter about Object Orientated programming in SC, but for now it is enough to think that the object (an instantiation of the class) has relevant methods. \dur, Pwrand(#[0.25, 0.5, 0.75, 1], #[2, 3, 1, 1].normalizeSum, inf) Out.ar(out, (sig * env).dup); In SuperCollider, patterns are best for tasks that need to produce sequences, or streams, of information. The ++ means concatenate, by the way. ) So try to run this code (by double clicking behind the first bracket). \amp, Pseq([0.3, Pn(0.1, inf)], 1), Loop 2017 - To view your own schedule, hover over your profile picture and choose "My Sched". && stands for and These files are compiled every time SuperCollider is started and become the application environment we are using. Often when writing SuperCollider code, you will experience errors whose origin you can’t figure out. ), var i = array.indexOfGreaterThan(val); loop / repeat. More on that later. post just means print without a new line at the end. Real-time audio synthesis engine and music programming language. We have now seen things as 100.rand and a.reverse. // identify the buffer numbers to read 4, ... input = Pan2. This car can then have some methods, for instance: start, drive, turn, putWipersOn. Environment SuperCollider version: 3.10 Operating system: Linux (doesn't matter) Steps to reproduce Two crashes with very similar input code. // for fun, change tempo Example: Another looping technique is to use the for-loop: We might also want to use the forBy-loop: This is enough about the language. Let’s take one example that should demonstrate clearly why they are useful: As you can see, the ‘freq’ variable is used in various places in the above synthesizer. fork { Try dumping LFSaw for example, UGen.browse // examine methods interactively in a GUI (OSX), SinOsc.dumpFullInterface // list all methods for the classhierarchically So to really understand a class like Array or List you need to read the documentation and explore the methods available. \rate, Pfunc { thisThread.clock.tempo / originalTempo } TempoClock.default.tempo = 1; beatsInLoop = 4, s.sync; Help.gui or simply Cmd+D or Ctrl+D (uppercase D). Then you can jump back and forth in the array, scratching, cutting, break beating or whatever you would like to do, but the fact is that this is all done with data (the samples of your soundfile) stored in an array. != stands for not equal \accent, Pseq([2, Pn(0, inf)], 1), sig = Klank.ar(`[ // which equals ) 0, Pbind( If you add a new class to SuperCollider, you need to recompile the language (there is a menu item for that), or simply start again. \time, Pkey(\dur) / Pfunc { thisThread.clock.tempo }, But note that we're only posting after we've done the 10000 iterations. For that, Phasor and BufRd are probably the best choice. You can think of this like names for values. The segment beginning (0.404561) and ending (3.185917) are important. It is up to you how you format your code, but you'd typically want to keep it readable for yourself in the future and other readers too. So this following code: will not work unless you highlight all three lines. \dur, Pwrand([0.25, Pn(0.125, 2)], #[0.8, 0.2], inf), The semicolon ";" is what divides one instruction from the next. Why not? Note that this argument has been put into the right position inside the calculation. }).add; var a, b, div; Sequence individual loop segments alongside other patterns. Loop 10 – 12 Nov 2017, Funkhaus Berlin. Often these are numbers, but they don't have to be -- patterns can generate any kind of object. So if you highlight the word Array in an SC document and hit Cmd+d or Ctrl+d (d for documentation), you will get the documentation for that class. It includes introduction tutorials, overviews and documentation for almost every class in SuperCollider. In many programming languages this is done with a [for-loop] (http://en.wikipedia.org/wiki/For_loop): The above code will work in Java, C, JavaScript and many other languages. You have already posted into the post window (many other languages use a “print” and “println” for this purpose). SuperCollider contains quite a lot of examples of “syntax sugar”, i.e., where you can write things slightly differently for the sake of brevity (or perhaps aesthetics?). 2) If the original tempo is, as above, 86.289 bpm and you want to play at 72 bpm, you have to scale the sample's rate down by a factor of 72 / 86.289 = 0.83440531238049. A variable with the name ‘myvar’ could not be global – only single lowercase characters. MIDI note numbers are used for these calculations because it's a linear frequency scale and linear interpolation is easier than the exponential interpolation that would be required when using Hz. \dur, 1 Compare that with: We can now play a little bit with that function that we pass to the array creation: You might wonder why this is so fantastic or important. 0.5, Pbind( m is here an array with the following values: [ 0, 2, 3, 5, 7, 8, 10 ]. ~baseBuf = Buffer.alloc(s, ~midinotes.size, 1, { |buf| buf.setnMsg(0, ~midinotes.midicps) }); We will learn the basic key orientation practices of SuperCollider, that is how to run code, post into the post window and use the documentation system. \time, Pkey(\dur) / Pfunc { thisThread.clock.tempo }, Comments are red by default, but can be any colour (in the Format menu choose ‘syntax colorize’). Note: SuperCollider versions from 3.5 on have the default sound files that come with SuperCollider in a different location. \bufnum, Pfunc({ |ev| ~midinotes.indexInBetween(ev[\freq].cpsmidi) }) Fig 14.28: recirculating schroeder reverb . Break from a loop. On other systems, such as a Mac, you can simply copy MIDIFile.sc into your SuperCollider Extensions directory (typically [$HO… Reich built it from just five pitches arranged in a twelve-note pattern and performed on two instruments. A common thing a novice programmer typically does is to create lots of variables for data that could be stored in an array, so let’s dive straight into learning how to use arrays and lists. }).add; \accent, -0.6, \instrument, \bell, There is however a style of SC coding used for Tweeting, where the 140 character limit introduces interesting constraints for composers. }.play; doneAction: Done.freeSelf); It's no more difficult to play the layers in the independent event stream players, using the quant argument to ensure the proper synchronization. There is a method of the Integer class that is called isPrime which comes in handy here. What happened is that it loops through the command 10 times and evaluates the function (which scrambles and posts the string we wrote) every time. if(msg[1] == recorder.nodeID, { A part of rhythmic electronic music that SuperCollider isn't so great at dealing with are loops. To add a session to your ... SuperCollider is an open-source media programming language that can be used for sound design, generative composition, performance, interactive music applications and more. Steve Reich’s Piano Phase (specifically the first movement as under discussion here) is a seminal work of early Minimalism. We can now put in any frequency and get the relevant MIDI note. Pfindur(4, Download SuperCollider for free. Yes. bufCount = ~midinotes.size; How does .rand and .reverse work? Unlike other… p = Pbind( There are two exceptions, all lowercase letters from a to z (note that ’s’ is a special variable that is by default used as a reference to the SC Server) can be used without declaration, and so can ‘environmental’ variables (which can be considered global within a certain context) and they start with the ‘~’ symbol. Also, if you want to read and browse all the documentation, you can open a help browser: var bufCount; SynthDef(\oneLoop, { |out, bufnum, start, time, amp, rate = 1| In the example above you could simply do ‘a = a.add(100.rand)’ if ‘a’ was an array, but many people like lists for reasons we will discuss later. o.free; Playback tempo: In principle, you can choose any tempo you like. s.sync; \instrument, \bell, Since there isn't an instrument sample in the SuperCollider distribution, we will record a frequency-modulation sample into a buffer before running the pattern.// make a sound sample Here, keys are keywords that are identifiers for slots in the collection. supercollider; audacity; loop; swa_ June 25th, 2016 33 downloads 0 comments The 2013 International SuperCollider Symposium, May 20-24, 2013 in Boulder, Colorado USA SC Symposium 2013 Submission Deadline Non-standard Synthesis: Techniques, Aesthetics, Extensions (seminar led by Luc Döbereiner) Here we will use PlayBuf, which doesn't allow looping over a specific region.
