Use an Array of mp3 files which when on keyPressed plays a random selection from it at the same time

vincepat

I know it seems convoluted, Im struggling to play more than one track at a time using minim. I would like to know how to set up an array of maybe 10 tracks I have (bass,chords,melody etc), then on a key command to play a random selection of maybe four of the ten tracks at the same time, ?

Is this difficult to do? Any pointers very much appreciated.

Thanks GoToLoop

I read it but don't fully grasp it.

I need to add an array of mp3's

then on key press play a selection of them at the same time.

Ive managed it with images using PImage and for loop but the sound files I can't figure out.

Any pointers?

I assume you already call play() in order to play an AudioPlayer from your array.
My advice is to also call rewind() before play().

@vincepat Are you wanting to play a synchronized mix of selected tracks - as if using a multichannel mixer? If so I'm not sure Minim can do this. I looked at it as that is what I wanted to do a while back, but could only find a way to play single files.

Hi Hudson - yes I'm trying to play maybe 3 tracks simultaneously on a key press. Then an another key press would play another 3 tracks, all randomly picked from an array of 10+ .mp3s.

GotoLoop - thanks I'll give that a go.

Genuinely appreciate the support thanks

Just had a quick look at the minim docs and think that it may be worth trying AudioSample instead of AudioPlayer?

Im struggling

Minim minim;
AudioSample[] songArray = new AudioSample [10];

void setup()
{
  size(100, 100);
   minim = new Minim(this);
 for (int i = 0 ; i < 3 ; i++) {
  songArray[i] = minim.loadSample("sound" + i +".mp3");
 }
  for (int p = 0 ; p < 3 ; p++) {
  songArray[p] = minim.loadSample("sounds" + p +".mp3");
 }
  for (int s = 0 ; s < 4 ; s++) {
  songArray[s] = minim.loadSample("soundss" + s +".mp3");
 }

}

void draw()
{

}

 void mousePressed(){

 .play();

 }

This is what I have so far.
