The sketch demonstrates how to shape the p5.Oscillator class using an Envelope in order to create short “windows” of sound.
The sound is processed further with the p5.Biquad and p5.Delay class demonstrating how to “chain” effects.
Moving the mouse along the x-axis changes the biquad filter’s “center frequency” making the note sound brighter or more muffled.
Try to process sounds with other effects such as the p5.Reverb, p5.Panner, and p5.PitchShifter to create different effects.
