Data-flow programming for SuperCollider?

sndflo allows to program SuperCollider using the Flowhub visual data-flow IDE.

Status

Proof-of-concept working for wiring up Synth's.

Install

Note: Only tested on GNU/Linux. Should work fine on other platforms with minor adjustments in install.

Prerequities

• SuperCollider (version 3.5 or later)
• node.js

Install

git clone https://github.com/jonnor/sndflo.git
cd sndflo

# Install as SuperCollider extension, ref http://doc.sccode.org/Guides/UsingExtensions.html
# On Linux
mkdir -p ~/.local/share/SuperCollider/Extensions || true
ln -s `pwd` ~/.local/share/SuperCollider/Extensions/sndflo
# On Mac OSX
mkdir -p "$HOME/Library/Application Support/SuperCollider/Extensions" || true
ln -s `pwd` "$HOME/Library/Application Support/SuperCollider/Extensions/sndflo"

npm install -g node-gyp
npm install

Running

# For Mac OSX only, specify where sclang is
export PATH=$PATH:/Applications/SuperCollider/SuperCollider.app/Contents/Resources/

node sndflo.js --verbose --user MY_FLOWHUB_UUID

Will start up SuperCollider, loading the sndflo runtime and FBP protocol bridge. On success should output something like

Listening at WebSocket port 3569 
OSC send/receive ports:  57120 57122
Registered with Flowhub, should be accessible in UI

Go to http://app.flowhub.io, refresh the runtime list. You should see our sndflo runtime listed, be able to create projects for 'sndflo' and connect.

Note: on GNU/Linux sclang might fail with a segfault if X11 is not available. You can use xvfb-run to work around this.

Vision

• Program audio pipelines visually, by Synth's wiring together with Busses
• Program synths visually, by creating SynthDefs by combining UGens
• Do not replace sclang, integrate with it
  • Allow to use SynthDefs created in sclang in visual pipelines
  • Allow to drive visually created Synth pipelines using sclang Events/Patterns
• Seamless integration with other FBP
  • MicroFlo for communicating with microcontrollers (sensing/acting)
  • NoFlo for general-purpose use, and generating composition/scores
  • Combined audio processing with noflo-webaudio
• Program scores visually, using Streams and Patterns

Usecases

• Generative & algorithmic composed music
• Reactive and interactive art installations
• Audio effect pipelines, processing sound inputs
• Audio and music analysis, feature extraction
