My aim is to hook up a midi device to my computer to create and manipulate shapes in p5.js. I'm still learning code so have a few questions regarding arrays and keys.
Is there a way to say if any of the values in noteC, noteE and noteG are triggered then 'something happens'? But in a sort of combo as that is a chord as a opposed to say noteD and noteE which is not a chord.
Essentially I am trying to manipulate the shapes via chords being played but I am unaware of if "noteC + noteE + noteG" would do anything.
For example:
var noteC = [24, 36, 48, 60, 72, 84, 96, 108]
var noteE = [28, 40, 52, 64, 76, 88, 100]
var noteG = [31, 43, 55, 67, 79, 91, 103]
function keyPressed();
if (value ===noteC, noteE, noteG) {
ellipse(200, 200, 25, 30);
ellipse(200, 200, 50, 60);
ellipse(200, 200, 100, 100);
To do it without chords I imagine it would go something like:
function keyPressed() {
if (value ===36) {
ellipse(200, 200, 25, 30);
} else if (value === 40) {
ellipse(200, 200, 50, 60);
}
}
However manually transforming shapes separately away from any combination of chords feels static and I would like there to be a relationship between the manipulation if a chord is being played.
I would like it so that the scale of the ellipse is determined by the velocity of the keys being played but if it is part of a chord the x and y parameters will be the same.
Not asking for someone to do the code but if anyone could help me understand or point me in the right direction that would be great! Thanks!
