The video below shows some screenshots of the visual representation of sound objects created in Processing.

1. Setup

The code in Processing, which is available in this folder, works with Processing version 4.3 and requires the oscP5 external library to be installed in Processing, which is available in this folder or directly from the Internet.

In order for the sound data in SuperCollider to be transmitted via OSC in Processing :

1. The ~visualizeProcessing variable must be equal to 1 in the _0_Init_Live4Life.scd file. It is therefore necessary to evaluate the line after changing the variable to 1. See the start of the installation process in the ReadMe for information on how to evaluate a command line in SuperCollider.
2. The _3_Init_Pattern_182.scd file must be evaluated, either by selecting the whole file or simply with this line in the _0_Init_Live4Life.scd file. If this line has already been evaluated, stop the execution of certain language functions via Stop in the Language menu or the keyboard shortcut Control (on Windows) / Command (on Mac) + . and re-evaluate the _3_Init_Pattern_182.scd file as indicated above.

2. Details of sound data generated from SuperCollider and transmitted via OSC to Processing

Broadly speaking, two types of sound information are transmitted to Processing:

2.1. High-level information :

1. on each of the sound events (controlled by the GUI) coming from the language, such as :

• the track number or sequence number,
• the duration of the event,
• the number of the type of synthesis used,
• the amplitude,
• the type of volume envelope (percussive, Gaussian, etc.),
• the playback speed or frequency,
• the sound folder number, the sound folder type, the sound file number,
• the playback start position in the sound file,
• the type of spatialisation,,
• the send to speaker numbers or other spatial parameters depending on the type of spatialization,
• the send to effects tracks,
• as well as certain parameter variables associated with the type of synthesis.
