I’d like to now use the p5.sound.js library in conjunction with p5.svg.js, however, the latest version seems to not work with p5.js that is compatible with p5.svg.js.
The p5.js-svg seems to require and comes bundled with p5.js version 0.4.13. You could try using the p5.sound.js version that came with that version of p5.js.
