Online piano works but I want to eliminate static sound

p5.js Libraries
1

This code works(just copy and paste the sketch.js code below into the online p5.js editor: https://editor.p5js.org/ ) but every note plays emits a static-sound when the synth turns on. Can anyone suggest a way to eliminate the static sound? Maybe leave the synth running all the time and switching frequencies as notes are needed? Thank you.(to run this on your own editor you need p5.js and p5.sound.min.js files in your project folder.)
