Multiple audio, particle system onto a single window

Hello,

I am new to max and trying to figure out the software as I move along with my project. I recently found the recipe for particles and now I am tinkering with it. I want to use multiple audio inputs and generate particles for each of them separately. My problem is I couldn't figure out how to show them on a single window. I tried using drawto messages to the jit.gl.mesh objects but then I lose the trail effects. I am a little bit desperate at the moment so any help would be much appreciated.

Thanks.
