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
Patrick
