hi,

beginner here. how can i create a low frequency oscillator with adjustable frequency?
i am trying soundloop but i cant figure out how to adjust the tempo from a function with a slider.
other examples very welcome? maybe with pulse and amplitude?

thanks a lot for any help

Sound library included frequency examples

yes, thanks, i cant find it there. how can i change the soundloop interval from a function or change the bpm from a function?

osc = new p5.Oscillator(‘sine’);
osc.start();

soundLoop = new p5.SoundLoop(strt, interv);

soundLoop.start();

env = new p5.Envelope(0.1, 0.1, 0.1, 0.1);

}
function draw() {
background(220);

}
function strt() {
let r = random([1, 2, 4]);
let soundLoopinterv = r;
???
env.setADSR(0.1, 0.1, 0.1, 0.1,);
env.play(osc);
}
