Concentric circles

Hi all.

I’m struggling to get ‘clone to particles’ to emit a steady, even stream of particles…

I’m trying to constantly emit ‘rings’ from a central logo ring either towards the camera or uniform scaling…
These ‘rings’ also need react to a live audio input as they grow.

We’ve created a version using just cloners but we really need the rings to ‘emit’ from the centre of the screen.

Is it best to use clone to particles for this?

Many thanks
