Smoothing MIDI CC with Ani

bennigraf

Hi there!

I'm using the Ani library (http://www.looksgood.de/libraries/Ani/) to smooth out MIDI CC values I get from my QuNeo. I'm basically using the code below...

x and y are being smoothed out a little, but there are still many "bumbs". Is this the right way to do it? Are there just too many calls to this to be working effectively?

Are there other ways of smoothing this kind of data (without writing my own pseudo low pass filter)?

Thanks, Benni.

void setX(float _x) {
    Ani.to(this, 3.5, "x", _x);
}
void setY(float _y) {
    Ani.to(this, 3.5, "y", _y);
}    
void draw() {
    ellipse(x * width, (1-y) * height, 100, 100);
}

Try something like this: Ani.to(this, 3.5, "y", _y, Ani.EASING_MODE); where you replace Ani.EASING_MODE by any of the modes in this cheat sheet: http://www.looksgood.de/libraries/Ani/Ani_Cheat_Sheet.pdf. Not sure what the default behaviour is but picking a smoother curve might get rid of the bumbs.
