The SuperCollider synthesis server (scsynth) runs in a separate process or even on a separate machine so it is ideal for realtime networked music. As usual, I chose to use a base Debian “Wheezy” with all updates applied. Listing 1 has exactly the same effect as the one-line instruction, but it is much easier to read. The most interesting two are scide and sclang, but just for the record, sclangpipe_app is used by scvim, which in turn is a Vim-like front end for sclang, and scsynth is the server proper, which I’ll address shortly. In Debian, for example, you would do # apt-get install jackd1. In the second example, you just have to press Ctrl+Enter once while your cursor is on any of the lines to get both words of output. There seems to be a problem with JACK. If you look at the top left-hand corner of Figure 2 again, you’ll see that the wave starts at 0. If this is the case, you can download the contents of the following SuperCollider script: foxdot.scd. Figure 1: The SuperCollider IDE on startup. SuperCollider has been up and running on Linux since shortly after it was released as open source software. Most Linux distros contain precompiled packages of Jack in their repos, so you can usually just install it using your software manager. SuperCollider language environments (see below) are typically used, but other OSC-aware systems can be used such as Pure Data. Nearly all SuperCollider “commands” are really functions with a return value, and in this case, the only value the interpreter can find is the content of a. Once downloaded, open the file in SuperCollider and press Ctrl+Return to run it. To get a list of Quarks, type Quarks.gui in the SC IDE, press Ctrl+Enter, and click the Update Quarks Listing button in the window. The default multiplier of the sine oscillator is 1, so in the second argument of Pan2 (SinOsc.kr(0.5)), you only have to specify the frequency. Before you can begin, you have to run the SuperCollider server by entering. Extra care has to be put in working on this platform, especially with headphones, because programs can produce unexpectedly loud sounds regardless of system volume settings, potentially causing ear damage. To create a scope so you can use ab, you have to group the commands between brackets: Now when you place your cursor anywhere within the brackets and hit Ctrl+Enter, the value is assigned to ab correctly. This will make SuperCollider start listening for messages from FoxDot. Chromium-based MS Edge browser will soon be available for testing on Linux. Go to the folder with source, create a build folder, and cd to it: In the past two years, it has become really easy to install on Linux, and is packaged in distributions such as PlanetCCRMA and Pure:Dyne. I could go on, but writing about SuperCollider's programming language deserves a book in itself, and there a plenty of good ones online for free. If nothing happens in a reasonable stretch of time, check the SC IDE Post window for errors. The higher the number, the higher the pitch (261.26, by the way, is middle C). This program recycles the sinewave SynthDef seen earlier and, from lines 9 to 31, creates a simple window with three elements – a slider, a knob, and a button – to control the wave. In the first example, you have to press Ctrl+Enter on each line for each word to output. Figure 3: The scope method shows the wave as it plays. It features 400+ unit generators (“UGens”) for analysis, synthesis, and processing. Figure 2: Different types of sound waves. Building/compiling. As for the executables, SuperCollider installs scide, sclang, sclangpipe_app, scsynth, scvim, and supernova. By default, SuperCollider on Linux uses JACK, and the audio device selection is managed by the JACK server. instead of shutting them all down with the Ctrl+. The simplest sound you can generate with SuperCollider is an unfiltered and unmodulated wave, and the shortest way to do that is with an unnamed function (curly brackets enclose functions in SuperCollider): The SinOsc object calls a sine wave oscillator, similar to the image in the top left corner of Figure 2. It is now maintained and developed by an active and enthusiastic community. ServerOptions cannot override JACK's selection of audio hardware. Check for any errors in the Post window and make sure the volume of your headphones is up, but not too high: Mistakes in SC code tend to make SuperCollider's output very noisy, indeed, and you don't want to damage your headphones, speakers, or, worse, your eardrums. Now call the SynthDef (line 1) and pass it some parameters (line 2), or change the tone and volume as it plays: Although the SynthDef structures are very useful, they have certain limitations compared with functions. Emperor-OS is a new Linux distribution focused on programming, developing, and data science. In the past two years, it has become really easy to install on Linux, and is packaged in distributions such as PlanetCCRMA and Pure:Dyne. The first value, 261.26, is the frequency or pitch, measured in hertz (i.e., phases per second). The Easy Way: SuperCollider for Ubuntu can be installed from the SuperCollider PPA at Launchpad. You can use it for algorithmic composition and sequencing, finding new sound synthesis methods, connecting your app to external hardware including MIDI controllers, network music, writing GUIs and visual displays, or for your daily programming experiments. You can declare a single-character variable (which are all objects) just by setting it to a value: Note the semicolon that ends a command. Parameters appear within brackets. for example, you'll see a whole second of the wave instead of the default 100th of a second. 76% Upvoted. The community is very active and helpful, the center of activity. In Debian, for example, you would do. Interestingly, SuperCollider installs just fine without the package that contains the Jack daemon (jackd) proper; it’s only when you try to run the SuperCollider server (more about this below) that it will bomb and inform you that Jack is missing. Your SynthDef will then be loaded into the server every time it boots. To run SuperCollider commands, type them into the workspace and press Ctrl+Enter while the cursor is on the same line. Several workspaces can be accessed via tabs across the top of the window. SuperCollider is tested with: Windows 10 (32- and 64-bit) and MSVC 2017; macOS 10.13 with Xcode 9.4 and Xcode 10.1; Ubuntu 14.04 and … An intensive but gentle introduction to SuperCollider This five-day workshop welcomes participants of any discipline with or without prior programming or musical experience. Although described as “… an environment and programming language for real time audio synthesis and algorithmic composition,” it is much more than that, as you will see. It may instruct you to erase a directory, such as /home/[user]/.local/share/SuperCollider/quarks and run Quarks.gui again. It is free and open source software available for Windows, macOS, and Linux. After installing or deleting Quarks, you might have to update the libraries and help systems by clicking Language | Recompile Class Library. You can run it by entering sclang in a terminal window. The solution is quite easy: cd up out of the build directory and run. SuperCollider has been up and running on Linux since shortly after it was released as open source software. Installing on Linux If you are familiar with midi notation, you can give the value using the .midicps attribute: The second value in SinOsc is the phase offset in radians, which is the position from which the wave starts. It features 400+ unit generators (“UGens”) for analysis, synthesis, and processing. For starters, a SynthDef is compiled, then the server runs the compiled, static version every time it is called. To do so, use the var keyword. As with particle physics, sound creation and manipulation is difficult. The beta version for Ubuntu’s latest release is now available for testing. Submitting a new RFC or discussing an existing one is a great way to get involved, especially if you are looking for a way to contribute that doesn’t involve writing code or using a terminal. Please do drop by. The Button widget in line 16 creates a multistate button (with the values "Off" and "On") and starts and stops the sound depending on whether it transitions from one state to the other or vice versa. modifies the multiplier (volume) parameter of the sawtooth wave (Figure 2, middle row, far left; a twangy, guitar-like sound), with the sine oscillator. The scope at the end lets you see what’s happening. If your SynthDef is really useful, you can save it for future sessions by changing add to writeDefFile and executing the block. The following, for example, pans the sound from one speaker to the other: The Pan2 function is used to pan between two channels – the Pan4 function handles four-channel output – and takes as arguments the audio signal and a number between -1 (left) and +1 (right).
