Because we’re using a reverb effect, we never want to free the effect while we can still hear sound. Please read the SuperCollider documentation if you’d like to know more. Output: 34 Congratulations! To do this, we declare a SynthDef and send it the .add message to temporarily add it to the server. Similarly, we do not always want to free everything at the same time. To create a TempoClock, the first argument it takes is the tempo in beats per second. ), // And a pattern to play it: ~notes = [34, 31, 27, 29]; //midi notes If you set the \quant argument to an array, the first value will tell the Pbind on what beat  to schedule its first event (in number of beats, starting at 0), and the second value will tell the Pbind how long to wait before scheduling it: Pbind().play(t, quant: [0, 3]); //schedules on next division of 0 beats (i.e. In this workshop, Joanne Armitage will show participants how to get started making music with code in SuperCollider. envelope = EnvGen.kr(Env.perc(), doneAction: 2); //doneAction of 2 frees this synth when the envelope finishes Intro This tutorial assumes that you have a basic understanding of programming languages, have SuperCollider installed and running on your machine, and are familiar with the SuperCollider interface (including important keystrokes, compiling/executing code, etc.). As you can see, the limiter effect is structured the exact same way as the reverb effect. ] While we do so, let’s add another audio effect–a limiter, which prevents clipping–and route it after the reverb using a second bus: Pbind( SuperCollider Workshop in Mexico City | Algorithmic and Stochastic Music The 2013 International SuperCollider Symposium, May 20-24, 2013 in Boulder, Colorado … \amp, 0.9, amplitudes = Array.fill(5, {| i | amp * (1/i)}); //amplitudes of partials arr2 = Array.fill(n, { rrand(1, pi) }); trate = MouseY.kr(2,120,1); \addaction, 0, ), Audio clip: Adobe Flash Player (version 9 or above) is required to play this audio clip. So, to run audio through this effect, all we need to do is line up the output of the sound generator to the input of the audio effect. \outbus, ~reverb_bus, This music-making method relies heavily on the relationship between the Client (you, your code, and the interpreter) and the Server (make sure it’s booted with s.boot!). sustain=0.3, amp=0.1; When you create an object–specifically a synth–on the server it exists until it is freed, manually or otherwise. Then, we define a Group and add the synths in the correct order, the final order being: Tonal synth –> Reverb –> Limiter–>Speakers. A node is the allocated space for the synth, and is where the synth runs. This channel is actually a what is known as a “bus”, which routes audio signal from one place to another. s.queryAllNodes; //server can always be accessed as the variable s unless you overwrite it So, we specify the location of the tonal synth’s node to be before the node of the audio effect’s Synth using Synth.before(). var input = In.ar(inbus, 1); ( Knowing how exactly the .play function works (Event streams, etc.) Out.ar(outbus, final); //outputs to given channel or bus audio music programming-language c-plus-plus sound supercollider synthesis Now we have our synths and effects all hooked up correctly. * 400 + 500, 0.03, 0.003)}!2) frequencies = Array.fill(5, {| i | freq * i}); //frequencies of partials To declare a SynthDef, we give it a name argument (as a symbol or string) and a function that defines what the synth should do. Audio clip: Adobe Flash Player (version 9 or above) is required to play this audio clip. SynthDef(\tonal, { |freq = 440, amp = 0.5, outbus| dur = 1.2 / trate; Now let’s make some rhythm! At the end, of course, we remember to free everything. arg out, freq=440, prate=180, pwidth=0.5, It runs just about anywhere (thanks to everywhere SuperCollider runs – macOS, Windows, Linux and Linux platforms like Raspberry Pi) You can use it with the most popular live coding tools, so for the live code / algorave scene, it’s a breakthrough (they’ve got … When you route audio signal to an output channel (remember Out? (This is simple wrapper around writeSuperCollider that may not work well on all platforms.) 3.wait; //don't cut off the reverb! LFSaw.ar([1,0.99],[0,0.6],2000,2000).trunc([400,600])*[1,-1] z= Atari2600.ar(tone0, tone1, freq0, freq1, 15, 15); ),0.98)).dup*0.1}. node2.play; fork { x.free; //synth is gone! Patterns are the simplest way of creating music in SuperCollider because we can very easily convert arrays of frequencies or MIDI note numbers into played notes using Patterns. ~bass_durs = [4, 4, 4, 4]; writeSuperCollider "test.sc" $ scat [c,d,e] openSuperCollider:: HasSuperCollider a => a -> IO Source. ( SuperCollider syntax grammars for VSCode. Even if the code is not very sophisticated, it offers some possibilities not widely available in commercial sequencers, like arbitrary polyrhythms and some control over generated timing and amplitude variations. \freq, arr3 @@ i, Run and record SuperCollider code from within the IDE 2. 31 ~sounds = Group.new(); //Use Patterns to create music in real time. Add comment. Line.kr(pwidth, 0, sustain) My goal is to make this walkthrough as clear as possible while not dwelling on topics not directly related to the code. In this example, we define an output bus and a group, create bass line MIDI note and duration arrays (all the durations are 4 seconds, but will be converted to beats in our desired tempo later), and then use the arrays in Pseq creator functions that we pass into the correct arguments of the Pbind. The sc-users mailing list provides the main place for SuperCollider users (newcomers and old hands) to discuss all aspects of using SC.. sc-users mailing list; Other community resources: sccode - an online code sharing service; SuperCollider wiki - with code examples and other useful information…; Swiki - the old wiki; The newscores SC forum - an online forum with an area for SuperCollider users In our case, it is essential for the unit generators in the tonal synth to execute before the unit generators in the reverb effect–if this doesn’t happen, the reverb effect will not be applied properly. frequencies = Array.fill(5, {| i | freq * i}); //frequencies of partials If you feel you need a refresher, consider checking out this small tutorial. */ //Create your own sound generating synths (instruments),and sound… arr3 = Array.fill(n, { 1300 + 100.rand2 }); alright: Pieces that I don't care for too much. ~reverb_bus.free; if(i % 64 == 0) { arfill.value }; node2 = NodeProxy.audio(s, 2); ~limiter_bus = Bus.audio(s, 1); Then I generated the score with the following two lines of Python code: for i in range(0, 240): print 'i 1 ' + str(i * 2.8) + ' 33.6' The Csound csd is available for download here. Here’s the Processing code… way to make music in supercollider by defining synths and effects, routing audio correctly, and then playing the audio using patterns. 56228375. home url a-touch-of-music.blogspot.com. The .stop statement stops that particular Pbind from playing. ~limiter_bus.free; Now we’re cooking! In that code, a is a function, so a.release does not tell the synth to stop playing. Simply select-all and evaluate. Write music as a SuperCollider code string and open it. Having to free everything manually gets annoying and tiring pretty quickly. }).add; x = Synth(\tonal); //creates a default Synth on the server, plays it, and frees it. x.set(\freq, 550); //client sends a message to the server, telling it to change the frequency of x Otherwise, your audio output in the above example would come out mono instead of stereo, as the SynthDef will not have “reserved space” for an array of values.
