BuboQuark: Simple, hassle-free live coding
This repository is a collection of methods and hacks that I found to make live coding easier on SuperCollider. A secondary goal is to make that setup easy to install on other computers. This Quark is not bringing a lot of new features and it twists the langauge in a way that is highly personal. Internally, it relies a lot on JITLib, Patterns and NodeProxies.
Installation
To install the BuboQuark, simply run the following command in your favorite SC editor:
Quarks.install("https://github.com/Bubobubobubobubo/BuboQuark")
To make use of the existing synth definitions, you will have to install the mi-Ugens, a collection of SuperCollider UGens taken from Mutable Instruments module designs. Note that it is also preferable to install sc3-plugins, the official UGen extension suite for SuperCollider.
All the other dependencies will be installed automatically when installing the Quark.
How to use BuboQuark?
The main goal of BuboQuark is to provide everything you need to live code right out of the box. It is a balance between staying close to the initial language features while offering convenient shortcuts when possible:
- boot the server with a suitable configuration for live coding
- facililate the use of patterns and blending with audio functions
- simplify the use of
NodeProxyroles for FX and mixing - synchonize the clock with other applications
- share the audio signals easily with other applications
SuperCollider already possesses everything you need to do so. It is just not pre-arranged by default. It is a programming language after all, you have to do some work to get it right.
Booting the server
There is a Boot() pseudo-class that acts as a configuration file. This configuration file is rather classic:
- raises the conservative options of
Server.defaultto allow more connexions, more buffers, etc. - set the ProxySpace clock to use
LinkClockfor syncing with other applications - make the default environment a JITLib
ProxySpace - Set custom default paths for sample and SynthDefs loading
- Install a
StageLimiternot to blow up the speakers
The Boot() constructor takes three arguments:
configPath: path to a.scdconfiguration file that will be automatically loadedsamplePath: path to a folder containing your audio samples (in sub-folders)soundDevice: name of the sound device to use
All of these arguments are optional. However, they will default to my
configuration if not set. If you want to set one option but not the others, use
keywords arguments or nil values: Boot(soundDevice: "BlackHole 16ch").
Controlling the clock
The LinkClock is accessible through the c global variable. Be careful not to
override it. It behaves like a regular TempoClock with the usual methods.
There are a few useful methods to control it and to use it efficiently:
c.tempo: set or get the current tempo (will change other peers tempo)c.beatDur: duration of a beat
I use these methods very frequently when writing delay lines and time-based effects.
Events
I am using some Events as pseudo-classes to store some things I want to keep track on during the session (FX templates, SynthDef reference, etc). I am using :
-
d: Definitions (SynthDefs)d.list: list all the available SynthDefsd.params('synth_name'): list the parameters of a SynthDef
-
f: FX templates (DSP functions accessible through a simple name)
To use one of the effects, you can use the following syntax:
~my_ndef.fx(100, 0.5, f[\vardel]);
These are not really hard-coded. They are in my .scd configuration files. You
can ignore this section entirely if you do things differently!
Simplified Server/Gui Control
I like when SC panels stay on top of other applications by default:
Panic(): shortcut forCmdPeriod.run.Scope(): a scope that always stays on top!FScope(): a frequency scope that always stay on top!Gui(): a server GUI window that always stay on top!
Pattern tweaks
Patterns are powerful but writing them is long and can lead to a lot of typing errors. Moreover, they are often centered around list manipulation. BuboQuark defines a few helpers to transform a regular Array into various patterns:
[1, 2, 3, 4].pseq
Consider the source as a documentation. You will find all the additional methods
in BuboString or BuboArray. I am not entirely convinced by shortening the
most complex Pattern types because they are complex after all. Consider blending
the regular syntax with shortcuts when necessary.
Pbind
I don't like using keys because of the backslash (\), a symbol that is really hard to type on AZERTY keyboards. For that reason, I much prefer the ["my_pattern", instrument: 'plaits', dur: 2] syntax. I added a .pat method to convert an array into a Pbind. There are optional arguments to specify the fadeTime and quant for that pattern. Demo:
(
[
"name_of_pattern",
instrument: 'sinfb',
rel: Pbrown(0.1, 0.5, 0.125, inf),
note: Place([Pxrand([0, 3, 7, 10], 12), 0, 3, 5, 0, 12, 0, 7, 5, [5, 10, 7].pwhite(1)], inf),
octave: [Pxrand([5, 6, 4], 4)].pxrand(inf), dur: Pbjorklund2(6, 8, inf) / 2,
legato: 0.1
].pat.play;
)
.pat take a few optional arguments:
quant(defaults to4): pattern quantization (LinkClock)fade(defaults to0.05): fading time (NodeProxy)
There is also the .p function that will just turn the array into a Pbind without any additional behavior. This is useful when dealing with classic NodeProxy Roles like \set and \xset.
NodeProxy
The NodeProxy roles are sometimes a bit verbose to my taste. I have tried to make the syntax easier on the eye by creating the fx, wet and infx methods. Here is a demo of how I use it:
(
// Adding a tiny bit of reverb on slot 10 with a wet of 0.2
~test.fx(10, 0.2, {
arg in; GVerb.ar(in)
});
)
~test.wet(10, 0.5) // bring the reverb up with the wet method
There is also .fxin and .wet functions, shortcuts for the \filter and
\filterIn NodeProxy mechanisms. I have also added some rather shady functions
that automatically pick up a slot for a specific fx: fx1, fx2, up to fx9.
