CC Particle World Question

I am trying to make it particles look like they are shooting out from the large circle like shape at the bottom, and I am using CC Particle World due to it having the look I am going for. The particles' emitions are tied to music, and this is causing me an issue. I can set the producer to be the shape of the large particle so that the particles shoot off at the correct angles, but then the travel for those particles is very long making it not actually match with the music when the particles appear. I can set the producer to be smaller, but then the particles shoot off at the wrong angles. I wanted to ask if anyone had any advice or solutions to fix this problem. Thank you!
